ECONOMIC EVALUATIONS OF TAR SAND AND OIL SHALE RESOURCES IN THE STATE OF UTAH

FINAL REPORT ON PHASE I

EXECUTIVE SUMMARY

Managing public lands for maximum social benefit is becoming an increasingly complex task. The growing need for domestically produced mineral raw materials and energy, and the conflicting interests over the use of public lands, have added new dimensions to the management issues.

This report covers the first phase of a long-term program initiated by the Division of State Lands to improve their capability to evaluate the tar sand and oil shale resources in Utah. The scope of this phase of the study was limited to the examination and analysis of existing information and to the develop­ment models for data processing and resource evaluation. The study has been effective in identifying problem areas and demonstrating the potential value of the proposed systems for the management of state lands. The more important findings and conclusions are summarized below:

1. Data Storage and Retrieval

Ready access to information is an essential prere­quisite to effective land management. A demonstration model computer storage and retrieval system has been developed and is now available for use by the Division of State Lands. The acquisition of data and its insertion in the data bank in the required form is a long-term, ongoing project. For example, all drill hole sampling data should be stored as it becomes available so that land valuation will always be based on continuously updated information.

The scope of the data bank program should be further refined as the needs of the Division become clearer. In addition, the potential should be considered of extending this service to other departments and to include other types of mineral and energy resources in Utah.

2. Resource Characterization

Resource characterization defines the basic geologic data required for evaluation, namely, the quality and quantity of the resource. The economic resource includes only that portion of the geologic resource

v

that can be extracted at a profit. Hydrocarbons in tar sands and oil shales occur in interbedded beds of varying richness. For the purpose of evaluation it is necessary to identify the particular zone of beds (thickness) .that should be mined to yield optimum returns on investment capital. While significant work has been done to establish geologic resources in Utah, no provision exists for optimizing the commer­cially recoverable resource under varying physical and economic conditions. It is recommended that top priority be given to the development of reliable methods of quantifying the recoverable resource in defined land areas. This work will involve the analysis of all existing raw drill core data to demarcate economic horizons, and the application of geostatistical methods of estimating the recoverable resource from the sampling data of surrounding boreholes.

During the course of this study further work was completed on the analysis and interpretation of existing geologic data on the P.R. Spring tar sand deposit, which is mostly under state ownership. The total resource was calculated at some 1.9 billion barrels of crude oil in six different geological horizons. It is important to follow this work with an evaluation of the economic significance of this resource.

The work done on the P.R. Spring tar sand deposits demonstrates the potential value of further analytical study to define the resource boundaries. Another benefit is the identification of favorable areas for additional core drill exploration to extend the boundaries of known deposits or to discover new deposits. It is recommended that this program be continued to establish the State's resource base as an asset capable of supporting a major oil extraction industry.

3. Resource Evaluation

The term 'value' has many interpretations. In terms of public interest it may include qualitative values, such as aesthetic and recreational considerations, as well as the quantitative values such as direct and indirect contributions to the fiscal base, social benefits of job opportunities and infra-structure development, and the provision of essential mineral raw materials and energy.

For the purpose of this analysis 'value' has been interpreted as being the optimum amount of front end bonus that a prudent investor would bid to acquire a mining lease. A computer program has been developed and made available to the Division of State Lands

vi

that has the versatility to compute this value under a wide variety of resource, production, and economic conditions. However, the derivation of the data input to the computer program demands considerable technical expertise. The methodology of preparing estimates is demonstrated in this report by means of a model evaluation exercise. It is clear that the estimator must be experienced in mining and processing engineering, company accounting and costing, and computer applications.

Sensitivity analyses of the model evaluation indicates that the 'value' is very sensitive to estimates of resource grade and crude oil prices. In these circumstances it is suggested that the method of lease allocation should be reviewed to avoid the need for a front-end bonus based on such a volatile assessment of land value.

4. General

It is anticipated that effective evaluation of the oil shale and tar sand resources in Utah, supported by readily accessible physical data, will lead to improved management both in policy and in legislation so that a greater return to the public may be realized without discouraging hydrocarbon development. The use of these methods may be extended to other mineral resources and other departments to address regulatory, environ­mental, and social issues as well.

SECTION 1

Introduction

This report covers the work completed under the one-year contract awarded to the University of Utah commencing July 1, 1979. The contract called for the implementation of the research program, specified as Phase I in our proposal, which outlined a long-term program consisting of three consecutive phases:

"Phase I: An introductory study designed to identify gaps in current knowledge and to develop a methodology of evaluation. This program will occupy a period of one year and will include the following work:

Acquisition and consolidation of information held by various government agencies, such as the U.S. Bureau of Mines, the Department of Energy, the Utah Geological and Mineralogical Survey, and the U.S. Geological Survey. Also included will be information that may be released by the private sector. Missing and unavailable data will be identified and a program for the acquisition and generation of this data will be prepared.

Development of a suitable method of evaluation for a selected type of deposit which will serve as a model for the evaluation of other occurances.

Phase II: Implementation of the programs developed in Phase I, namely:

Acquisition of critical data. The program is expected to require some coring and sampling. Laboratory tests will be conducted on individual samples, both existing and newly acquired, on the basis of pre-established priorities.

Standard tests for the evaluation of oil shale and tar sand samples will be developed. Formal cooperation between state, federal, and private interests for coring and resource characterization is a possible option.

Extension of the methodology developed in Phase I to. evaluate all significant occurrences of tar sands and oil shales under state jurisdiction. This phase will take cognizance of the different chemical, physical, and special characteristics

- 2 -

of the various deposits as they affect the selection of mining method and extraction technology, with due regard to state policies regarding environmental protection and leasing conditions. The scope and time frame for Phase II, which is the heart of the program, will be established on the basis of the results obtained in Phase I.

Phase III: This is the final coordinating and documenta­tion phase. The ultimate objective will be to establish a comprehensive data bank which will serve as a base for future decision-making at state level regarding the development and optimum use of state lands in the public interest. While primary end users will probably be various state agencies, it would be the intention of this research to provide sufficient in-depth evaluation for the use of private industry in assessing commercial end^uses."

During the course of this contract it became apparent that continued funding to cover Phase II and Phase III of the proposed work program would not become available as originally planned due to current budgetary con­straints. As the result of discussion with senior executives of the Division of State Lands, it was agreed that every effort would be made during the remainder of the Phase I contract to enhance the immediate practical utility of the investigative work in progress with special reference to:

The development of the economic evaluation model to the stage where the computer program and valuation methodology could be used by personnel of the Division of State Lands for the practical evaluation of oil shale and tar sand resources in the State of Utah.

The development of a prototype computer data storage and retrieval system with the capability to be used by Division personnel as a basic data bank for pertinent surface, geological, and economic information pertaining to defined land areas underlain by tar sands or oil shale in the State of Utah.

The development of suitable methodology to conso­lidate existing data characterizing the oil shale and tar sand deposits in a form convenient for resource estimation and valuation.

We are pleased to report that the original purpose of the Phase I program has been accomplished while concurrently we have met the augmented objectives re­quested by the Division. The technologies outlined above have been developed to the stage of practical utility, and their application has been tested in relation to specific areas of state land selected as demonstration models. A more extensive application has not been possible in the limited time available, but detailed operator instruction manuals have been prepared, and are included as Appendices to this report. This will enable Division personnel to extend the applications to cover other relevant areas in the future. It must be emphasized, however, that these are first generation prototypes. Further developments and improvements should be made as experience is gained in their applica­tion to meet the needs of the Division of State Lands. In addition, we have endeavored to identify areas where long-term benefits may be gained by additional fundamental analysis and research. Specific recommendations are included under each section of this report to identify the work that remains to be done to achieve the full benefits from this progressive development program initiated by the Division of State Lands.

SECTION 2

The Economic Evaluation Model

In terms of the provisions of Section 65-1-18 of the Utah code, the State Land Board may issue mineral leases including, without limitation oil, gas, and hydorcarbon leases for prospecting, exploring, developing, and producing minerals covering any portion of the state lands or the reserved mineral interests in state lands. All mineral leases issued by the Board shall contain such terms and provisions as the Board deems to be in the best interest of the State of Utah. The mandate of this assignment was to develop a practical methodology to assist the Director of State Lands to assess the "value" of oil shale and tar sand resources located on state lands for the purpose of adjudicating mineral lease applications in the public interest.

2.1. Principles

The meaning of the word "value" of a mineral property is open to diverse interpretations. In this context, we will assume that a lease will be allocated on the basis of simultaneous competitive bidding plus a royalty of 5 percent of product sales revenue. Under these conditions, the "value" of a mineral resource can be measured in terms of the highest bonus bid that may be expectd from a responsible developer. Such a person would expect the proposed venture to generate a certain minimum return on capital investment under commercial exploitation conditions. The evaluation methodology, therefore, is designed to determine directly what level of bonus bid could be supported by the resource without destroying the investment incentive of the prospective developers.

The computer program DOSLOI simulates a comprehensive discounted cash flow calculation based on input data specific to the resource characteristics. It is fully described in Appendix 2.1., which includes a copy of the Fortran IV program, a standard pro forma for data input, a copy of the computer printout detailing the cash flow for each year in the life of the mine, and an operator instruction manual that will enable the program to be used as required by staff members of the Division of State Lands. Four principle criteria are calculated:

The venture capital required to bring the mine to the self -financing stage (measured in constant dollars as at time zero).

- 5 -

The pay-back period (PBP) calculated from the time of risk commitment (time zero).

The internal rate of return (IRR) on investor's funds (sometimes called the discounted cash flow rate of return).

The net present value (NPV).

The discount rate used to calculate the NPV is critical to the evaluation. Conceptually, it should represent the minimum rate of investment funds required to motivate a responsible investor to place his money at risk in the venture. The effect of inflation may cause some confusion. In this particular case, the computer program is designed to compensate for inflation internally; therefore, the discount rate used should represent the real rate of return expected by the investor assuming noninflationary circumstances (refer to Appendix 2.1 for a full explanation of the computer program). For the purpose of demonstration, we have used a discount rate of 15 percent. However, the computer program will accept any discount rate specified in the input data.

The conceptual meaning of the NPV suggests a conveni­ent method for calculating directly the maximum front-end expectation for a given property. To illustrate, let us make a preliminary assumption in the input data that no bonus payment is made. If the calculated NPV is zero, it means that the developer would only just achieve his minimum required rate of return provided he is not obligated to a front-end bonus commitment; if the NPV is negative, he would logically not wish to pursue the investment further; if the NPV is positive it means that a maximum front-end bonus equal to the NPV could be paid, and the investment would still satisfy the investor's required return on investment equal to the discount rate. A positive NPV, therefore, is a direct measure of the maximum amount of bonus that a responsible investor is likely to offer, and by definition it becomes a fair assessment of the "value" of the resource.

The above evaluation is based on the premise that the resource base under consideration is at least suffici­ent to support a viable mining venture. A mineral resource in the ground has no value whatsoever if it cannot be extracted economically, either because the grade is too low or because the quantity of available ore is not enough to support a viable mine. For example,

- 6 -

much of the state land in Utah is in the form of isolated 1 mile x 1 mile sections, any one of which would have zero commercial value unless the resource were suffici­ently well developed to support a mine on its own. However, such a section would immediately assume "value" if it could be mined in conjunction with contiguous areas. Three basic methods of valuing isolated sections of land may be adopted, dependent on the following assumptions:

Value each section on its own capability to support a feasible mining unit.

Assume that the section will be mined as part of a larger mining area comprising contiguous sections of exactly similar characteristics, together aggregating a total resource base large enough to support an economic mining unit, say producing 50,000 barrels/day of refinery crude oil for a life span of 20 years.

- Assume that the section will be mined as one .unit in a cooperative mining venture comprising a number of relatively nearby sections, where each section will produce crude shale oil which will be transported to a central upgrading unit capable of producing say 50,000 barrels/day of refinery'crude oil.

The computer program has the capability to handle virtually any variety of conditions. The input data format is designed for flexibility to cover different types and combinations of mining, retorting, and upgrading technologies. Consequently, the computer facility provides not only a means of valuing specific project proposals, but is also a quick and effective facility for optimization to identify the condiitons most suited to the public interest. Furthermore, the amount of detail provided in the very comprehensive computer print-out provides a sound basis for analysis and negoti­ation because cause and effect can readily be traced through the matrix of year-by-year figures. For example, the effect of changes in leasing conditions (bonus and/or royalty) can be clearly seen when comparing the print-outs for alternate proposals.

The format for data input is fully described in Appendix 2.1. (Specimen A2.1.3). It is comprised of the most likely estimates of quantities, costs, and revenues for the particular project under considera-

- 7 -

tion. The reliability of the valuation can be no better than the quality of these estimates. It must be stressed that all estimates at this time are purely analytic in nature because no viable oil shale project exists. Although present methodologies may be adapted for oil shale exploitation, the sheer magnitude of the undertaking renders extrapolation uncertain. Estimates for surface retorting and upgrading are even more uncertain since no precedent exists and only very general plant layout guidelines are available. In addition, technological improvements can be expected in process designs. These will improve conversion efficiencies and reduce costs by better utilization of energy by-products, such as waste heat and combustible gases, and increase revenues by the production of other by-products. Spent shale disposal, environmental protection, provision of water, and product transportation also present major cost uncer­tainties. Added to the above cost uncertainties are the imponderables of product selling price and inter­national monetary instability. As a result, any assess­ment of resource value is indicative rather than defini­tive. As uncertainties are resolved through agreed-upon assumptions, the economic value takes on practical significance.

Unfortunately, the existing system calls for some measure of value to be made at the present time when insufficient data are available to make the evaluation with some degree of confidence. The same problem faces both the developer and the land owner. In both cases the quality of the estimates can be improved by basing them on detailed technological studies and engineering design work. The Division of State Lands should have access to facilities at least comparable to those avail­able to the developer if equivalent estimates are to be made. Failing such facilities, the public interest may perhaps best be served by considering alternative leasing arrangements not dependent on an a priori valu­ation of mineral property. For example, a method of calculating lease payments as a proportion of operating profits would be self-adjusting to the ultimate commercial value of the property. Such methods have been success­fully applied to mineral leases in other parts of the world.

2.2 The Model

To demonstrate the evaluation methodology, we have selected a typical section of state land underlain by commercial quality oil shale. Section 32 of Township 11 S Range 24 E contains high-grade oil shale strata of which 60 feet averages 25 gallons/ton (Ritzma^) under

- 8 -

approximately 500 feet of cover (Casion ' ).

The first requirement in the evaluation procedure is to identify the best method of exploitation. While many different mining methods may be used, the preferred ones can be broadly identified by reference to two principle parameters, the thickness of the expected pay zone and the depth of cover over this zone. A broad classification is made on this basis in Table 2.1., but it must be recognized that the class boundaries will overlap appreciably. Mined oil shale will be retorted on the surface unless otherwise stated. We have selected room and pillar multiple-cut underground mining combined with surface retorting and surface disposal of spent shale as the preferred exploitation method.

TABLE 2.1: CLASSIFICATION OF EXPLOITATION METHODS

Let us assume that this section of state land can be combined with contiguous sections with exactly the same characteristics to form an economic unit capable of producing 50,000 barrels of refinery crude oil per day for 20 years. The total resource requirement is calculated allowing 6.25 percent dusting and retorting losses, and 4 percent loss in volume in upgrading.

The planning of the commercial exploitation of this resource would normally require the full-time attention of a team of highly qualified mining and process engineers for a period of years. Even then, a prudent early developer would enter the field with caution, bulk testing new technology before final commitment of major funds for expansion to ultimate capacity targets. Such a program has been developed by the White River Shale Project as a Detailed Development Plan for commer­cial exploitation of the ,U-a and U-b federal oil shale lease tracts. This is a most comprehensive analysis of prototype underground mining and surface processing plant design, and we have, therefore, based our economic analysis on this program. In particular we have made the following assumptions:

The entire project will be energy self-sufficient. That is, the production of high Btu gas will meet the requirements of the upgrading plant; excess high and low Btu gas will be used to generate the electric power requirements of the entire operation at a direct operating cost of 0.70 per KWhr; sufficient diesel fuel will be produced to meet the requirements of all diesel-operated equipment.

- Refinery grade crude oil will be sold at a net realization price ex-tankage on-site. That is, no provision is made for product transportation. (No by-product sales are included.)

- 10 -

Water requirements will be drawn from underground dewatering at approximately 700 gpm, and the balance will be purchased at commercial rates from the White River Dam. Provision is made for local storage and reticulation on the mine.

No provision is made for off-site road improve­ment and off-site employee housing.

It is assumed that the technology has been fully proved in practice so that no provision need be made for prior prototype testing.

The crux of the evaluation lies in the estimation of capital expenditure and working costs on a year-by-year schedule for the life span of the mine. For the purpose of demonstrating the evaluation methodology, cost estimates have been made (Appendix 2.1). The computer data proforma has been filled out (Specimen A2.1.2-5), and the program run on the University of Utah UNIVAC 1108 computer. The computer printout (Speci-nen A2.1-1) details the year-by-year cash flow and gives the following evaluation criteria:

Venture Capital = $866 million

PBP = 10 years

IRR on Venture Capital = 14.66%

NPV on Equity Capital = -$19.2 million

PVR on Equity Capital - .96

2.3 Sensitivity Analysis

The computer provides the capability for rapid mathematical processing of input data according to rigidly specified program instructions. In practice, it is often desirable to examine the effect of changing the values of specific input data because estimates are uncertain and because of the need to consider differ­ent design concepts. The sensitivity of the performance criteria to a change in the value of a selected parameter can be tested by repeated calculations, each time altering the value of the parameter concerned while keeping all other data constant at a standard value which repre­sents the control condition. In this analysis we have used as the control reference the values determined for the demonstration model, namely,

Average depth of overburden 500 feet

Figure 2.1 indicates how the net present value will be affected by a change in the net product selling price. The break-even value appears to be at about $26 per barrel, but it is noteworthy that $3 per barrel either way will make a difference of $10Q million in the NPV. As explained earlier, the NPV is a measure of the amount of front-end bonus a responsible developer can justifiably offer. The extreme sensitivity to product price makes it unrealistic to base the lease consideration on such a valuation, both from the point of view of the State and the developer. The developer must protect his interests in the event that the selling price of crude oil does not meet expectations, whereas the State will not receive a fair return if the selling price exceeds expectations.

2.3.2. Grade of Ore

The NPV is also very sensitive to the grade of ore (Figure 2:2), although not quite as sensitive as the previous.case. It must be remembered that the standard production rate is 50,000 barrels per day of refinery quality crude oil. This means that the scale of mining and retorting will vary in relation to the average grade of the ore mined. A further implica­tion is that the area of land required to provide the necessary resource base will increase as the grade decreases. If it is required to determine the pro­rata value of any portion of the total land involved, it will be necessary to adjust the NPV for the acreage concerned.

2.3.3. Size of Production Unit

The size of the production unit in terms of barrels per day of syncrude produced affects the NPV as shown in Figure 2.3. The NPV is, of course, influenced by the size of the capital investment, and it must be remembered that a greater area of land will be utilized for a larger size mine. However, Figure 2.4. shows that the NPV value per acre increases monotonically in sympathy with the size of the mine. This effect is a direct result of the extremely high fixed capital investment required for this type of enterprise.

In Figure 2.5., it is seen that the NPV is relatively insensitive to the depth of overburden, This is because the total investment in mining operations, which are dependent on depth, is relatively insignificant in comparison to the very large investment in other facili­ties.

The thickness of the mining zone, within the limits applicable to room and pillar mining methods, is not very critical to the NPV provided the requisite resource is available (Figure 2.6.). However, the NPV value per acre of ground will, of course, be highly sensitive to the thickness of the resource.

2.4. Recommendations

The evaluation of a mining project is a complex operation requiring the services and technical expertise of experienced personnel with practical backgrounds in mining and processing engineering, company accounting and costing, and computer applications. While the computer operation can accept data in stardardized form, the derivation of the data will always demand an individual with technical expertise to prepare realistic estimates. It is recommended that the Division of State Lands acquire the services of such a person if it intends to undertake responsibility for mineral land evaluations.

Even with competent estimating the sensitivity analyses confirm that the land "value," in terms of a potential front-end bonus payment, is extremely sensitive to imponderables such as predictions of future crude oil price. Under current conditions oil shale and tar sand exploitation is a high-risk venture, and it can be expect that potential developers will be cautious in pitching their bids for lease allocation.

- 17 -

Even if the bids appear to be satisfactory today, it is possible that very high profits in the future may make today's bids look like a "give away." Under these circumstances it is strongly recommended that the method of lease allocation should be critically reviewed to avoid the need to base a front-end bonus on such a volatile estimate of land value. In principle, a lease consideration based on corporate profits will automatically adjust to circumstances from time to time, and in the long run the state is likely to receive benefits far in excess of those accrued under the present system.

SECTION 3

Information Storage & Retrieval System

3.1. Introdcution

The increasing availability and reduced costs of owning and operating high-powered computer facilities has given rise to a proliferation of data processing systems that store vast quantities of information that can be readily retrieved or used by subsidiary programs for further processing. Applications for this type of "data bank" in the geologic and mining fields is widespread. For example, raw explorat ion data in the form of borehole core logs can be stored and subsequently retrieved as input data for reprocessing by subsidiary programs to perform any or all of the following calcula­tions :

Calculation of composite averages along each borehole with identification of economic ore zones, overburden cover, and included waste thickness.

Computation and presentation of plans showing grade contours, isopachs, depth of overburden, surface contours, etc.

Derivation of mining plans and calculation of minable ore reserves.

Economic evaluation of different mining programs.

The value of information and processing service to government agencies responsible for administering mineral development on public lands is self-evident. Part of the mandate for this research assignment was to review data banks with a view to adapting suitable systems to the needs of the Division of State Lands. A brief list of some of the more compatible systems available in the public sector is given below:

CRIB (Computerized Resource Information Bank): Available through USGS, Denver. This is essentially a mineral resource information system containing geolgic data concerning particular mineral depostis. Some tar sand data has been entered in this system by the Utah Geological and Mineral Survey.

NRCDS (National Coal Resource Data System): This is an "in-house" USGS system resident on their IBM computer in Reston, Virginia. Mapping and contouring subsidiary programs are available. It is related to tabular-type deposits of significant areal extent and is most nearly aligned with the type of service required for tar sand and oil shale.

OSDA (Oil Shale Data System): Magnetic tape containing raw oil shale Fischer assay logs for core holes in the Green River formation. (Only information in the public sector.) Available from NTIS (PB 682/AS and PB-236 068/AS).

PDS (Petroleum Data System): USGS, Denver. This system is essentially designed to store oil well reservoir data and is not suitable for oil shales, although core logs may give some additional strata information not available through OSDA.

WHCS (Well History Control System): Historic statistics regarding oil well exploitation.

MAS (Minerals Available System): USBM. this sys­tem endeavors to cover all information regarding the availability of specific minerals on a U.S. and world basis. It characterizes deposits, mining methods, economic calculations, etc. Much of the information is proprietary and cannot be released outside the USBM.

GQDM (Groundwater Quality Data Management): Developed and operated by TEMPO, General Electric's Center for Advanced Studies. TEMPO has done major work in the area of water quality monitoring for the EPA, especially in coal strip mining and oil shale development. A Utah oil shale program focuses on the U-a and U-b tract leases.

While many of the above systems contain features that would be of value to the Division of State Lands, none of them entirely meets the current requirements of the Division. Consequently, it was decided to examine the development of an individualized system capable of direct access to the University of Utah UNIVAC 1108 system from a terminal located in the downtown offices of the Division. The suggested guidelines to the Divi­sion's requirements were outlined in a letter dated March 27, 1980 as follows:

- 20 -

"...We want information which we can use in making management decisions relative to the leasing of State oil shale and tar sands lands and the eventual production of these products from these lands. To meet theses requirements, I would suggest the following data be included in your system design:

1. Geographic location - reference to section, township, and range and subdividing sections to as small as possible units. If possible, reference to the Utah Coordinate Systems should be included.

2. Topographic data and depth of overburden over the oil shale and tar sand deposits.

3. Quantity of oil shale and tar sands deposits thickness of beds, depth from surface,

barren rocks separating productive beds, etc.

4. Quality of oil shale and tar sands deposits -chemical composition and reserve data.

5. Hydrologic data - water quantity and quality.

6. Climatologic data.

7. Transportation data - requirements and routes for exploration, mining and marketing of production and work force."

Under the above mandate, a prototype data storage and retrieval system has been developed. This system is fully described in Appendix 3.1., which contains operating instructions on how to access the program; how to insert, change or delete information; and how to retrieve all or selected data referring to any section of land.

3.2. Description of Database System

The database and the database maintenance program were developed to achieve maximum flexibility and portability. Flexibility was incorporated to allow maximum use of the program. Portability was included into the design so that the program could easily be adapted for use on a variety of computer systems.

Flexibility is . an important design factor due to the nonuniformity of a deposit over an entire section. As a result of this flexibility, the program may be used for deposits other than oil shale and tar sands. It is recommended that a slight modification be made

- 21 -

to the program before it is used extensively for other types of deposits. Another area of flexibility is the provision to use the program either interactively from a computer terminal or from a batch environment utilizing cards as the input media.

The program was designed to be portable to allow easy transfer of the system to a variety of computers. The program was made portable by writing it in the ANSI standard Fortran 77 programming language. A change of the CHARACTER statement to say INTEGER will make the program compatible to ANSI standard FORTRAN IV (1966 standards). This should allow the program to be transferred to virtually all computer systems which have a Fortran compiler (providing sufficient memory is available.).

3.3 Information Stored

The database is designed to store information related "to the evaluation of the mineral worth of a section. The information stored includes section identifi­cation, coordinates of corners, elevation of section corners, land use, land classification, transportation/ utilities, geological, mineralization, hydrological, and ecological information.

The section identification essentially designates the ownership/lease status of a section. A section may be in either private ownership, Indian lands, state lands (leased, unleased), federal lands (leased, unleased), or a mixture of the above. The program allows for these types of designations.

The land use information about a section indicates what the land is currently being used for. A section might be used for agricultural, grazing, mining, recreation, or residential purposes.

The transportation/utility information concerns the location of transportation routes and utilities within a section. These could include roads, powerlines, railroads, pipelines, rivers, and canals. A digitization of the route through a section can be included with this particular program.

Geological information is a limited summary of the geology of a section. It may include the location of oil and gas wells, outcrops, coreholes, and the existence of present underground or surface workings. Core logs can be incorporated into the input of the geological information as well as digitization of an outcrop.

- 22 -

Mineralization information is a summary of the .mineral occurrence within a section. If the occurrence is either oil shale or tar sands, additional information concerning cover, thickness, grade and recoverable tons are required. If the mineralization is coal, gilsonite, oil, gas, or any other, additional information is not required; however, it may be incorporated into the database.

Hydrological and ecological information in the database is a summary of those two divisions. Drainages or wildlife counts may be incorporated with the summary.

Structure of the Program

The structure of the database maintenance program is illustrated in Figure 3.1. The structure is simply a main driving routine soliciting commands which specify certain tasks to perform on the database. These commands are ADD, DELETE, EXAMINE, REPORT, STOP, or PACK. The main driver upon receiving one of these commands transfers execution to the appropriate subroutine.

DELETE

Figure 3.1. - Structure of Database Program

There are several small subroutines not illustrated in Figure 3.1 which are utilized. These can be classified into two categories. The first category are input routines which read the information required about a section. The second set are output routines used to report the information within the database structure. The first three letters in the input subroutines are GET. The first three letters of the output routines are OUT.

The program utilizes three random access mass storage files. The first file contains a list of entries in the database. The second file contains pointers to the third file, indicating the location of the various data stored on that section concerning land use, roads, mineralization, etc.

File one is read into core at the start of the program. This allows the use of high speed core memory when searching for an entry and updating an entry. At the termination of the program the updated block of entry information is copied back to file number one.

- 25 -

Structure of File One

File one consists of records 13 characters in length. The records in this file indicate the sections that are contained within the database. The first character is a designation of the meridian of the section and is either the letter "S" standing for the Salt Lake meridian or the letter "U" for the Uintah meridian. The next three characters in file one are the township and direction (example 14N). Characters 5-7 are the range and direction. The section number is stored in characters 8 and 9 of the record. Characters 10-13 hold a pointer to file two. This pointer denotes an entry in file two which contains a list of pointers to the various data stored. The structure of the file one is outlined in Table 3.1.

Structure of File Two

Entries in file two are primarily pointers to detail information stored in file three. The entries in file two are 68 characters in length. Each of these characters are summarized in Table 3.2. The first character; is either "N", "C", or "S" representing either the north, central or south state plane coordinate system. The rest of the entries in the database should be self-explanatory.

Structure of File Three

The structure of file three varies depending on the data being stored in any one record. Essentially,

Running the Program

A form of input must be decided upon before running the program. Input may be either a terminal or a card deck. If input is from a terminal, then the program runs interactively. If the input is from a card deck, then the program accepts input as though it were a batch job. Appendix 3.1 outlines the procedures.

With either form of input, if an entry is to be added to the database, it would be helpful to fill out Forms A-H (located in Appendix 3.1.3) before running the program. If an entry is to be changed, it would be helpful to fill out the appropriate form before using the program.

- 27 -

All that is involved with running the program is selecting a command (see Table 3.3) to operate on the database and then supplying the necessary information required by the command. The procedures for doing this are located in the appendix associated with the form of input being used.

The PACK command is one that requires special comment. The PACK command should be used periodically to get rid of deleted records in the database. It only needs to be used if a lot of changes or deletions have been done to the database. It should be used with extreme caution, however. If tffte computer should go down during a pack, the database will be destroyed. For this reason one should copy the unpacked database files to a back-up file before packing the database. If the pack is successful, then the back-up files can be deleted.

3.4 Conclusions and Recommendations

i. It must be recognized that while the prototype system that has been developed is fully operational within its current limitations, it has not been possible in the limited time available to derive factual data for insertion in the system. The acquisition of this data in the required form, and its insertion in the data bank, is seen as a long-term project requiring the full-time services of a technically qualified person. Such a person should be knowledgeable in the fields of geology, mining engineering, and computer applications. He/she would also take responsibility for characterizing resources as outlined in Section 4, and or economic evaluations as outlined in Section 2.

- 28 -

ii. The scope of the database program should be further developed as the needs of the Division become clearer. Two courses of action are possible. One would be to expand the present prototype system, the other would be to integrate the Division's needs with a commercially available existing system. In the latter case, it is possible that much of the ancillary data processing services will be available through the system already developed.

iii. In considering future needs, the potential should be examined to extend the service to other departments and other types of mineral resources within the State of Utah. For example, data on oil shale would be valuable to the Division of Oil, Gas and Mining in the event that exploitation eventually takes place. This division is responsible for regulatory action—an essential prerequisite to such action is continuous monitoring and storage and retrieval of data. The data bank could be adapted to provide this service with little structural modification.

iv. Certain computer hardware will be necessary to operate this service from the offices of the Division of State Lands. For interactive operation, the minimum requirement will be a direct access terminal. A CRT is convenient for quick access, but a teletype terminal would be necessary if hard copy printouts are required. It may be possible to handle batch work utilizing card decks through the existing Harris facilities.

v. The program is designed for use on the University of Utah UNIVAC 1108/60. There will be an on-going charge for data file storage and access facilities. This charge will depend upon the volume of information kept in storage, but certain nominal charges will accrue even for minimum storage. If the program will not be used for some time, it would probably be worth trans­ferring it to magnetic tape or punched cards at a cost of about $30.00. It can then be reaccessed as and when required. In any event, it will be necessary to open- a user charge account to qualify for access to the computer facility.

vi. The database and the database maintenance program were developed to maximize flexibility and portability. The following is a discussion of the improvements and additions to the program which have not been incorporated, but should be considered for follow-on work.

Improvements\ The biggest improvement to the database would be to change file one to a

- 29 -

sorted file. A file of entries that are sorted can be used to minimize access time for the location of a section. However, the advantage of having the file sorted is only seen when there are a large number of entries in the database (this is why this scheme was not used initially).

Another improvement to the database program would be to have the lines of text in the individual note sections "reside in a "packed" format in file 3. This would eliminate unused space that is being wasted in file 3 if a line in the notes is less than 60 characters in length.

At present, the program requires that a change to an entry necessitates reentering all informa­tion associated with the area of change. In other words, when changing the "geology" of a section, one must input all of the good data as well as the changes, e.g. if an addi­tional corehole is added to the database it is necessary to reenter all of the existing coreholes, outcrops, etc., as well as the new data. This should be changed if additional funds should become available.

Additions: There are many possible additions to the program that can be made to help facilitate the valuation of a section of land. These would include graphic routines, interpolation routines, economic valuation routines—all directly interfaced with the database. Addi­tions of this nature would simplify and speed up the process of assigning a value to a section of land.

The database was developed with the future addition of graphic routines in mind. The digitized input of outcrops and roads were designed as part of the input so that they could be readily plotted by a graphic routine. Graphics would enable the plotting of several contiguous sections in order to better assess the impact of existing roads, rivers, pipelines, etc.

Interpolation schemes and programs could be inter­faced to the database which would eliminate the need to input thickness, grade, tonnage, overburden, and average grade data. An interpola­tion routine could be used to determine this information, based on coreholes in an area.

- 30 -

Valuation routines could be interfaced with the database structure to help provide a current value of a parcel of land. This would give a user a quick and easy way of determining the value of a section.

Other additions to the database could be made quite easily. If additional information is desired to be stored, all that is needed is a "GET" routine to place the information into the database and an "OUT" routine to get the information back from the routine. Of course, the addition also requires additional pointers which will have to be stored in file 2.

Remarks: The database is very flexible. It can be used to store information about tonnage, grade, etc., of other minerals such as lead, zinc, silver. However, it was designed primarily for use with oil shale and tar sands operations.

It is recommended that additional funding be provided so that some of these changes and additions can be introduced. At the present time, the flexibility and usefulness of the database are limited by the inability to obtain good data for input into the database. More research is needed to ascertain the nature of deposits within the State of Utah before the full potential of the database system can be realized.

SECTION 4

Resource Characterization

Resource characterization provides the basis for evaluation. It is the means by which the quality and quantity of the resource is expressed. There are two fundamentally different concepts of resource measurement. The geologic resource (in-situ resource) encompasses the entire development of mineralization irrespective of whether it can be economically exploited as a whole or in part. The economic resource (recoverable resource) includes only that portion of the total mineralization that can be economically exploited; it is a function of the particular chemical and physical characteristics of a selected portion of the deposit, such as the average grade, physical dimensions, and depth below surface. An economic evaluation must clearly be calculated on the economic resource base.

Part of the problem of evaluation is to identify the particular portion of the geologic resource most suitable for exploitation. Here we have a conflict of interest. The commercial developer is interested in maximizing his return on investment, whereas the state may be more interested in maximizing the resource utilization. In the case of tar sands and oil shales, these two objectives may not differ significantly because even the richest portions of these resources can today barely support economic exploitation. That is, in order to qualify for commercial development, it is necessary to identify a "pay zone" of high-grade strata.

The pay zone is normally identified by determining a cutoff value below which it is uneconomic to mine. The determination of the optimum cutoff value is a complex evaluation. For the purpose of this analysis, let us consider the effect of varying the cutoff value. Figure 4.1 is a typical value profile along a borehole core penetrating the oil shale horizon. It is clearly necessary for a potential developer to select the inter­cept which will be eonomically exploitable. This is done by applying a cutoff value, say 20 gallons per ton as shown in Figure 4.1, and determining a pay zone for which, on average, values exceed the cutoff value. The: average value of this pay zone will clearly be somewhat higher than that of the cutoff. The economic viability can thus be calculated for differing cutoff values to determine the optimum cutoff grade.

a map in January 1980 which gives isopachs of the thick­ness of oil shale which will yield an average of 25 gallons of crude shale oil per ton. This map is based on earlier unpublished work done by Casion 2 (1968) which also indicates the thickness of overburden covering the mahogany oil shale horizon. It is difficult to assess the basis on which the average value of 25 gallons per ton was derived, and there is no way of making any other selection which may be more economically favorable. For example, the contours in the above map indicate that a 25 gallon per ton pay zone averaging 110 feet thick underlies the U-a/U-b Federal lease tracts, yet the zone selected for mining in the White River DDP is 55 feet thick at 27 gallons per ton. Clearly, it is considered that this selection is econom­ically more attractive than mining a zone of twice the thickness at a lower yield.

In 1978, the Laramie Energy Research Center published a report on 'Colorado Primary Oil Shale Resource for Vertical Modified In-Situ Processes' (John Ward Smith3, et el.). In this report the potential exploitation zone was defined.

The bottom of this developable section is placed at the top of BB-groove, because BB-groove tends to be an acquifer, complicating any development which includes it. The top of this developable section is defined at the top of the continuous oil shale uninterrupted by a 25-foot section averag­ing less than 5 gallons per ton oil yield.

The report continues:

To complete the description of the continuous oil-shale resource overlying mahogany zone and A-groove, five additional oil-shale units were established. These units are also bounded by time lines, connecting the oil-yield histograms.

The Laramie Energy Research Institute has extended the above analysis into the State of Utah. The report is due for publication in the near future. However, its usefulness for evaluation purposes will be limited because it is essentially a measurement of geologic resources within predefined geologic boundaries, which may not necessarily correspond to the optimum economic selection. In addition, there is no facility for making other selections.

It appears that for the purpose of evaluation, it may be necessary to revert to primary analysis of raw borehole data. Such data is available in the form of a database on magnetic tape obtainable from the

- 34 -

NTIS (OSDA - refer to Section 2). In principle, the analysis could be completely computerized once the basic logic has been developed. However, this would involve fundamental research to develop satisfactory statistical methods of interpolation to estimate the average pay zone thickness and value for defined areas, given only the data of surrounding borehole cores.

4.2 Tar Sands Resources

The characterization of tar sands resources is less well defined than that of oil shales. In addition, the nature of the tar sands deposits differs widely from that of oil shale. Ritzma^ describes the tar sands development in the State of Utah as follows:

Utah's 53 deposits of oil-impregnated rock are mainly grouped within and around the Uinta Basin of northeast Utah and in the central southeast part of the State; 25 deposits are. in the Uinta Basin and 22 in the central southeast. Six minor or small deposits occur in the northwest, southwest and far southeast parts of the State.... Oil contained in these deposits originated in the. same way as oil found in conventional oil fields. The source was organic material contained within rocks laid down in situations in which the organic material was converted to petroleum. The petroleum has been trapped by fortuitous stratigraphic or structural conditions close to its area of origin (in-situ deposit) or has migrated unknown distances to become trapped at another locality (migrated ' deposit)....

Due to the genesis of tar sands deposits, they occur in isolated deposits with little or no stratigraphic correlation between deposits. While broad methods of interpolation are acceptable for oil shales, in the case of tar sands each deposit must be examined individually. While indicative estimates of geologic resources have been made, very little detailed mapping of the individual deposits has been done.

Under the aegis of this research contract, it was decided to examine the potential value of tar sands through more detailed analysis and mapping of deposits. In cooperation with the Utah Geological and Mineral Survey and under the direction of Howard Ritzma, Consult­ing Geologist John N. Dahm was commissioned to examine the P.R. Spring deposit. As a result of his interpreta­tion of data, he has identified some 1.9 billion barrels of crude oil in six different horizons in this deposit.

- 35 -

His report appears as Appendix 4.1. An inventory of the state lands showing occurrences of oil shale and tar sands, and a general description of the status of our knowledge, appears in Appendix 4.2.

4.3. Recommendations

- No valid evaluation of the mineral worth of state lands can be made unless the econom­ically recoverable resources can be defined. Preferably it should be possible to select the pay zone to optimize the commercial value of the mineralized land. It is recommended that top priority be given to the development of a methodology to determine the recoverable oil shale resource base for defined areas of land. This will involve a geo-statistical analysis to establish optimum estimating methods and the development of computer programs to handle the volume of calculations. The benefit of such a program to the state may be measured in enhanced capability to evaluate land value, with consequent improved management of public land leasing.

The work done on the P.R. Spring tar sands deposits demonstrates the potential returns that can be expected from more detailed analyses of existing geological data. Another benefit is that it identifed the areas where data are inadequate for resource identification. That is, it identifies the locations where additional core drilling will deliver maximum benefit in terms of measurable additions to the currently delineated resource base. It is recommended that this primary analysis and mapping activity be pursued to establish the state's resource base as an asset capable of supporting a viable oil extraction industry.

APPENDIX 2.1

Description and Operating Instructions for Computer Valuation Program DOSL01-FOR

DOSL01-FOR is a self-contained computer program designed to perform the calculations required to compute discounted cash flow measures of "value" for a tar sand or oil shale exploitation project. The program is structured and the data input is flexible so that they can be used for practically any underground or surface mining method combined with either surface or underground retorting with or without subsequent upgrading to refinerey quality crude oil. This program is described under three headings:

The Computer Printout (Specimen A2.1.1) (See page 38A)

The Input Data Pro Forma (Specimen A2.1.2 and A2.1.3)

The Fortran IV Program (Specimen A2.1.4)

The Computer Printout (Specimen A2.1.1)

The printout is arranged in logical matrix form so that the derivation of the year-by-year net cash flow can easily be followed by anyone familiar with mine accounting and taxation procedures. No special knowledge of computer methods is required to interpret this presentation, but it is necessary to have a working knowledge of the arithmetic in order to fully understand the true meaning of the various statistics. Much of the analytical and manipulative flexibility of this program will be lost in the absence of such understanding. The following general description refers to the computer printout subtended as Specimen A2.1:

Heading Items

Tax Advantage Received from Parent Company: The program offers two options, selected according to the value given to a "flag" in the input data. The option chosen for this evaluation assumes that a parent company can take pre-production tax benefits as they accrue; these benefits are credited to the project in lines 40 and 42.

The second option assumes that there is no parent company so tax benefits must be deferred until the company makes a taxable profit.

Bonus Payment on Lease: This is the amount of front-end bonus paid by the leasee. It can be treated in two ways. If payment is made before time zero, it will enter the cost basis for calculation of cost depletion but will not directly affect the cash flow. If payment is made after time zero, it will be used for calculating cost depletion, but it should also be entered in data line 45 (year 1) where it will directly affect the cash flow.

Downpayment for Land Acquisition: If this outlay is made before time zero, it will not enter the cash flow. If it is made after time zero, it should also be entered in data line 44 (year 1) where it will directly affect the cash flow.

Capitalized Legal Expenses: Expenses related to the acquisition of mining rights. If accrued before time zero, this outlay will enter the cost basis for calculating cost depletion. If payment is made after time zero, it will enter the cost basis but should also be entered in data line 45 (year 1) where it will directly affect the cash flow.

Equity Issued at Time Zero: This may refer to a going concern mine or to the condition where equity is raised by public subscription to fund a new mine. It will automatically enter line 56 in the column for time zero.

Limit of Equity funding: If cash available in any year is not sufficient to meet cash commitments, the program will make up the deficit in one of two ways:

1. If current equity is less than the "equity limit" it will meet the deficit by increas­ing equity funding up to the specific limit (line 56), e.g., funds drawn from parent company.

ii. If the "equity limit" has been reached, the deficit will be made up by nonscheduled loan funding (line 58). This facility is useful for testing the effect of finan­cial gearing. For example, if the equity limit is fixed at half the venture capital, the first half will be raised by equity funding and the remainder by loan financing.

- 40 -

Interest on loans will automatically be cal­culated and entered as a working cost in line 26.

Loan Balance at Time Zero: Any outstanding loan at time zero. This is automatically carried forward to the column for time zero, line 54. Loan repayments must be scheduled as data input on line 48.

Cash Funds' Available at Time Zero: Cash may he available at time zero in the form of unspent equity funds, unspent balance of existing loans, or as undistributed profits in the case of a going concern mine. This amount is automatically carried forward to the column for time zero, line 49.

Accumulated Tax Loss at Time Zero: This only applies to the valuation of a going concern mine. It is automatically carried forward to the column for time zero, line 35.

Interest Rate on Scheduled Loans: This is the predetermined rate of interest payable on preplanned loan financing (data lines 53 • and 48).

Interest Rate on Nonscheduled Loan: Loans ini­tiated by the computer to make up cash deficits will accrue interest during their currency at this rate. Interest from both nonscheduled and scheduled loans is debited as a working cost on line 26.

Interest Rate Received on Invested Funds: If cash available is more than cash demand for any year, the excess will automatically be committed as follows: Non-scheduled loan repayment will receive first priority; any excess after settling all outstanding loan commitments will be disbursed as dividends. If funds are required to be held for future development, they may be retained by scheduled deposits to "reserve: in data line 49. Such funds will earn interest at the rate specified which will feature as revenue in line 16.

Interest Rate for Calculation of NVP: This is minimum rate of return required by the developer to motivate investment.

- 41 -

Statutory Depletion Rate: Rate mandated by law for the calculation of depletion allowance on line 33 (15% for oil shale).

Royalty per Dollars of Gross Revenue: Rate at which royalty is payable under the lease agreement.

Ore Reserve Tons Available for Mining: The in-s itu resource available, excluding pillars and other areas that will be left unmined.

Matrix Lines

All lines identified as DATA require direct input from an input data file for each year in the life of the mine (see Input Data Pro Forma. Specimen A2.2). One data entry is required for each year in the life of the mine starting from time zero. All other lines are calculated by the computer as per the calculation reference (where given).

(1) DATA Annual Rate of Inflation: The estimated inflation rate in terms of percent per annum.

(2) Cumulative Inflation Factor: This is the cumula­tive index of inflation in relation to 1 at time zero.

(3) Cumulative Deflation Factor: This is the recip­rocal of (2) above. It is used to convert the project net cash flow (line 63) to constant dollars as at time zero (line 64).

(4) DATA Escalation Factor - Product Sales Price: If the sales price increases at exactly the rate of inflation, this factor will be 1; if the rate of increase is greater than inflation, it will be greater than 1; a factor less than 1 means a rate of increase less than that of inflation. Estimates of product sales price in 1981 dollars are converted to current dollars by multiplying by the product of (2) * (4).

(5) DATA Escalation Factor - Working Costs: As for (4) above.

(6) DATA Escalation Factor - Capital Costs: As for (4) above.

(7) DATA Tons Raw Shale Mined (1000): The yearly tonnage of raw shale mined and delivered to the processing plant.

- 42 r

(8) DATA Fischer Assay grade (Gal/Ton): The content of raw oil as measured by the Fischer Laboratory Retort.

(9) DATA Gravimetric Waste/Ore Ratio: In respect to open pit mining, this is the ratio of tons of waste material mined and dumped to the tons of ore mined and sent to the processing plant.

(10) 7 * 9 Tons of Waste Mined: As per the calcula­tion reference.

(11) DATA Overall Recovery: The purpose is to derive the quantity of saleable product pro­duced, after taking account of all process losses, e.g. crushing, retorting, and upgrading. The recovery factor is expressed as a percent­age.

(12) 7'.* 8 * 11 Barrels Syncrude Produced: (7) *-(8) *• (11) 42 * 100

(13) DATA Net Realization per Barrel: New sales dol­lars per. barrel of refinery grade crude oil in tanks on site. That is, the cost of sales and transportation is deducted from the' refinery price.

(14) 12 * 13 Net Revenue from Sales: As per calcula­tion reference.

(15) DATA Revenue from Other Sources: This line is provided to accommodate any additional revenue, other than product sales and interest.

(16) Interest from Invested Reserves: Interest is calculated on "Funds Allocated to Reserve" (Line 49) at the rate specified.

(17) 1 4 + 1 5 + 16 Gross Revenue Received: As per cal­culation reference.

(18) DATA Unit Working Cost - Ore Mining: This is the direct cost of labor, supervision, consumables, and services in dollars per ton mined and delivered to the surface stockpile. It does not include allocated expenses for general administration, depreciation, taxation, inter­est, or insurance. It will normally include on-going development to replace depleted mining blocks.

(19) DATA Unit Working Cost - Retorting: This is the direct cost of labor, supervision, consumables, and services in dollars per ton treated in the retort plant, which includes the secondary crushing, retorting, and spent shale disposal.

(19A)DATA Unit working cost - Upgrading: This is the direct cost of labor, supervision, consumables, and services in dollars per barrel of upgraded refinery-quality crude oil produced.

(20) DATA Unit Working Cost - Waste Mining: This is the direct cost of labor, supervision, consum­ables, and services in dollars per ton of waste mined and dumped.

(21) 7 * 18 Annual Cost - Ore Mining: As per calcula­tions reference.

(23) 10 * 20 Annual Cost - Waste Mining: As per calcu­lation reference.

(24) 21 + 22 + 22A + 23 Direct Working Cost: As per calculation reference.

(25) DATA Fixed Costs + Special Development: Special development is nonrecurring excavation and associated direct costs for the purpose of opening up and preparing new areas for mining. For example, all pre-production labor, supervi­sion, consumables, and services expended on preparing access to initial mining blocks; also similar expenses for subsequent work such- as sinking additional shafts or expanding production. Fixed Costs are those cost commit­ments which are not directly associated with the volume of production and are, therefore, not included in (18) through (20). For example, general head office administration research and development, engineering, insurance, legal, general environmental costs, etc. Capital costs, depreciation, and taxes are accounted for under separate headings.

(27) DATA Expensed Exploration Costs: It is assumed that all exploration costs are expensed. If there is a parent company these costs

- 44 -

are absorbed into the tax loss and the tax benefit is credited to the project, but they must be "recaptured" from depletion when it accrues. If there is no parent company, this process can be deferred up to 7 years. (In this case, no tax benefit accrues because cf the legal requirement to recapture from the depletion allowance.)

(28) DATA Royalty Payments: Provision is made for two types of royalty. A fixed annual- amount may be scheduled as input data. Alternatively or in addition, the royalty can be calculated by the computer on the basis of the specified percent of product sales revenue. (A small adjustment to the program will allow royalty to be calculated on the basis of tons mined.)

(29) 24 + 25 + 26 + 27 + 28 Gross Mining Costs: As per calculation reference.

(30) 17-29 Gross Mining Income: As per calculation ref­erence .

(31) Depreciation/Amortization: Capital Costs are scheduled in a 6 x 40 array (Capex) in the input data file. For each year in the life of the mine, capital costs can be classified into six different "vintage accounts" according to "Class life" for depreciation. Depreciation is calculated by straight line method for the first category (class life 3 years or less) and last category (class life equal to life of mine for buildings); the double declining balance method is used for the other accounts. Total annual depreciation is entered on line 31.

(32) (30-31)/2 Limit of Statutory Depletion: As per calculation reference.

(33) Statutory Depletion: Calculated at the statu­tory rate on gross revenue from product sales less royalty (adjusted for bonus tonnage pro rata).

(34) Cost Depletion: Calculated en tonnage pro rata of cost basis, where the costs basis consists of bonus plus mining rights acquisition cost.

(35) Tax Loss B/F (Maximum 7 Years): If the parent company takes immediate tax loss benefit (line 39), no tax loss is carried forward. If there is no parent company, the accumulated

- 45 -

tax loss is carried forward, but any individual year's tax loss is dropped after 7 years.

(36) 30 - 31 - Depletion - 35 Taxable Income: As per calculation reference where depletion is the higher of cost or statutory depletion and where statutory depletion is limited to the amount calculated on line 32.

(37) State Tax: A bulk allowance of 7 percent of tax­able income is made to cover all state taxes.

(38) (36 -37) * 46 Federal Tax: As per calculation reference.

(39) Tax Loss Taken by Parent Company: If taxable income is negative (line 36), the tax loss can be taken by the parent company as it accrues. If there is no parent company, the tax loss must be carried forward on line 35.

(40) Tax Credit Received-from Parent Company: The tax benefit received from the parent company is credited to the project on this line.

(41) Investment Tax Credit Accrued (B/F Maximum 7 years): Investment tax credit of 10% of qualifying property (classes 1 through 5 of Capex) can be taken as it accrues by the parent company, subject to limitations or profit. If there is no parent company, accrued credits are carried forward until the project becomes liable for federal tax (not to exceed 7 years).

(42) Investment Tax Credit Taken This Year: The parent company benefit is credited to the project (or the amount taken by the company when it qualifies).

(43) 37 + 38 - 40 - 42 Net Tax Liability: As per cal­culation reference. If parent company tax benefits are credited to the project, this amount will be negative, meaning an equivalent income from taxation.

(44) DATA Deferred Land Payments/Recovery: Planned payments for the acquisition of surface land rights may be scheduled here. These outlays affect the cash flow, but are not taken into account as costs for calculation of tax. If it is expected that these rights will be sold when the mine closes down, the expected

- 46 -

selling price is entered as a negative amount in the last year of the life of the mine.

(45) DATA Deferred Mining Rights Payments: Similar to 44. For example, deferred payment of bonus under a lease agreement.

(46) Working Capital Provision/Recovery: Similar to 44.

(47) Capex Schedule - Capital Assets Purchased: This is the total expenditure for the acquisition of capital assets each year. (The amounts are adjusted for inflation and escalation.)

(48) DATA Funds Allocated to Reserve: This schedule is used to immobilize funds for future use, e.g. pre production capital funds or sinking fund provision for future development.

In the preproduction period it is usual to commie slightly more funds than are available in order to prevent the program paying dividends if a surplus eventuates (it must be remembered that all funds committed to reserve will earn interest, thus increasing the accrued revenue). The computer will raise a loan to meet any funding deficit. A small line of credit is not unusual when major funds are committed to longer term investment.

(50) 4 3 + 4 4 + 4 5 + 4 7 + 4 8 Gross Funds Committed: As per calculation reference.

(51) Reserves Brought Forward: Each year the funds com­mitted to reserve the previous year are brought forward as available cash for the current year.

(52) DATA Assets Sold at Book Value: This line pro­vides for the disposal of assets at book value (to avoid tax complications). For example, the sale of temporary shaft sinking equipment no longer required.

(53) DATA Scheduled Loans Raised: Preplanned loan financing.

(54) Accumulated Scheduled Loans: Loan interest is calculated on the total of current loan prin­ciple.

- 47 -

(55) 30 + 51 + 52 + 53 Gross Funds Accrued: As per calculation reference.

(56) New Equity Capital Raised: If line 50 exceeds line 55, the deficit will be made up by raising additional equity provided the equity limit is not exceeded.

(57) Cumulative' Equity Capital: Gross equity capitali­zation.

(58) Nonscheduled Loans Raised: If there is a cash deficit and the equity limit has been reached, the computer will finance the deficit from loan financing.

(59) Nonscheduled Loan Repayment: If there is a cash surplus, the first call on the funds will be to liquidate nonscheduled loans.

(60) 60 Prev. + 5 8 - 5 9 Accumulated Nonscheduled Loans: As per calculation reference.

(61) Cash Available for Dividend Payment: Surplus Cash after liquidation of loans is available for distribution to shareholders.

(62) 30 + 52 + 49 - 50 - 59 Project Net Cash Flow (Cur­rent Money): This line gives the cash flow profile over the life of the mine (excluding outside funding and distributions to share holders).

(63) Project Net Cash Flow (Constant Money): Amounts in line 62 are converted to constant dollars (at time zero) by multiplying by the factor in line 3.

(64) PV of Net Cash Flow: Amounts in line 63 are converted to present value at the rate of interest specified for calculation of NPV, assuming all amounts accrue midway through the year.

Criteria of Investment Worth

Venture Capital (Constant Money) : This is the amount of money in constant dollars required to bring the venture to the self-financing stage. It is the accumulation of negative

- 48 -

amounts in line 63 until the first positive value is recorded.

Pay Back Period in Years: The number of years -measured from time zero until the venture capital is recaptured from accrued profits.

IRR on Equity Capital: The calculated discount rate which will satisfy the following formula:

n I. m o.

2 L_ = 2 1_— i=l (1+r)1 j=l (l+r)J

where Ii is the equity capital raised for the year i, and Oj is the dividend paid to shareholders for year j (all in constant dollars). The computer calculates the interest rate r to satisfy this equation by testing incremental increases in r, and finally interpo­lates when the required condition is straddled. The value of the increments is specified in the data input. The smaller the increments the more precise the result, at the cost of more computer time.

NPV ON Equity Capital: This is calculated by the computer as follows:

m 0. n I. NPV = 2 -L,— = £ K

2=1 (l+r)J i=l (1+r) L

where the discount rate r is specified in the data input.

PVR ON Equity Capital: This is calculated by the computer as follows:

m 0. / n I. PVR = 2 -J-,— / Z — K—

j=l (1+r) * / 1=1 (1+r)1

using the same discount rate r as for the NPV.

The Input Data Pro Forma (Specimen A2.1.2)

This data input worksheet is designed to facilitate the compilation of the data input file. Once the values are entered in the appropriate blocks by the responsible

- 49 -

technical person, they can be readily punched onto computer cards or entered on the terminal by a computer operater.

A data record is a series of digits, separated by commas, which will exactly satisfy the aprticular "read" statement of the computer program. It can be entered on one or more cards (lines), but more than one record or portion of a record may not be entered on the same card (line). Real numbers must contain a decimal point. Integer numbers must not contain a decimal point (all mnemonics commencing with the characters i, j, k, 1, m, n are integers).

cular year is not sufficient to meet cash commitments, the program will make up the deficit in one of two ways:

i. If current equity is less than the "equity limit" it will meet the deficit by increasing equity fund­ing up to the specified limit, e.g. funds provided by parent company.

ii. If the "equity limit" has been reached, the deficit will be made up by nonscheduled loan funding. This facility is used to test the effect of financial gearing. For example, if the equity limit is set at half the venture capital, the first half of the required capital funding will be raised by equity financing and the balance by loan financing.

Outstanding loan principle as at time zero.

Available cash resources as at time zero.

This may be made up of unspent equity funds and/or unspent loan funds, or retained earnings.

Accumulated tax loss as at time zero.

Interest rate in percent paid for scheduled loans.

Interest rate in percent paid for non-scheduled loans.

Interst rate in percent received on invested funds (reserve).

Matrix Data

Reference numbers correspond to the relevant line numbers on the computer printout (Specimen A2.1.1). Each record must contain exactly the number of entries corresponding to the "life" of the mine - blank spaces must be represented by zero entries.

(I) Annual Rate of Inflation: The estimated monetary inflation rate in terms of percent per annum for each year in the life of the mine.

(4) Escalation Factor - Product Sales Price: If the product sales price is estimated to increase at exactly the rate as inflation, this factor is 1; if the rate of increase is greater than1 inflation, it is greater than 1; a factor less than 1 means a rate of increase less than that of inflation.

(7) Tons Ore Mined (1000): The yearly tonnage of ore mined and delivered to the processing plant.

(8) Fischer Assay Grade (Gal/Ton): The crude oil content of the ore as measured by the Fischer Laboratory Retort.

(9) Gravimetric Waste/Ore Ratio: In respect to open pit mining, this is the ratio of tons of waste material mined and dumped to the tons of ore mined and sent to the processing plant.

(II) Overall Recovery: The percentage of the oil con­tent of the ore mined which will ultimately be recovered and sold. This takes account of all process losses, e.g., crushing, dusting, retorting, upgrading.

(13) Net Realization per Barrel: Net sales dollars per barrel of refinery grade crude oil in tanks on site (the cost of sales and transpor­tation is deducted from the refinery price).

(15) Revenue from other Sources: Any additional reve­nue received other than for product sales and interest.

(18) Unit Working Cost - Ore Mining: The direct cost of labor, supervison, consumables, and services in dollars per ton mined and delivered to the surface stockpile; including on-going development to replace depleted mining blocks. It does not include allocated expenses of general administration, depreciation, taxation, interest, or insurance.

(19) Unit Working Cost - Retorting: The direct cost of labor supervision, consumables and services in dollars per ton treated in the retort plant (secondaray crushing and screening, retorting, and spent shale disposal).

(20) Unit Working Cost - Waste Mining: The direct cost of labor, supervision, consumables, and services in dolars per ton of waste mined and sent to the waste dump.

(25) Fixed Costs and Special Development: Special development is nonrecurring excavation and asso­ciated direct costs for the purpose of opening up and preparing new areas for mining. For example, all preproduction labor, supervision, consumables, and services exoended on preparing access to initial mining; aLso, similar expenses for subsequent work such as sinking additional shafts or expanding production.

Fixed costs are those costs which are not directly associated with the volume of produc­tion (working costs). For example, general head office administration, research and development, engineering, insurance, legal, general environmental, etc.

(27) Expensed Exploration Costs: Costs involved in seeking for ore not yet delineated, e.g., core drilling.

(28) Royalty Payments: A fixed anual amount of roy­alty may be scheduled as input data here.

(46) Working Capital Provision/Recovery: Provision of working funds to cover expenses incurred before receipt of cash from sales and to find inventory and stockpile.

(48) Scheduled Loan Repayments: Scheduled principal repayments for preplanned loans.

(49) Funds Allocated to Reserve: Available funds not required in the current year are placed in reserve so that the computer will not disburse this cash resource to liquidate loans or pay dividends.

(52) Assets Sold at Book Value: Temporary shaft sink­ing equipment or other redundant machinery may be sold when no longer required. Sales are presumed at book value to avoid tax compli­cations.

(53) Scheduled Loans Raised: Preplanned loan finan­cing.

The Capex Schedule. Capital expenditure is scheduled in" the form of one record for each year, where each record contains six entries representing the allocation to depreciation class life vintage accounts as specified by the first record in the data input file. For example, we may have the following vintage accounts.

1. Class Life 3 years:. All mobile equipment with an economic life up to 5 years, e.g., trucks, run-abouts, service vehicles, etc.

2. Class Life 8 years: Medium mobile equipment with an economic life up to 10 years, e.g., off-road haul trucks, light drilling equipment, compressors, etc.

3. Class Life 12 years: Heavy mobile equipment with an economic life up to 15 years, e.g., front-end loaders, bulldozers, rotary drills, etc.

4. Class Life Equal to Life of Mine (30+ years): Installed fixed machinery such as hoists, crushers, and very large power shovels, etc.

- 54 -

5. Not Allocated - enter zero.

6. Building and Structures (life equal to life of mine): Buildings and structures are grouped together because they do not qualify for investment tax credit.

The date recorded on the pro forma can be punched onto computer cards for batch processing in conjunction with a program card deck, or it can be typed on a direct access terminal. In the latter case, the input file must be given a suitable data identification for interactive access by the computer. Specimen A2.1.3 is a printout of the data input file D0SL2'DAT used for the model evaluation.

The Computer Program (Specimen A2.1.4)

The computer program is written in the Fortran IV language which is compatible with most computer installations. It is included with this report so that it can be used as a reference in the event that more specific information concerning the calculations is required.

APPENDIX 2.2

BASIS OF COST ESTIMATING FOR MODEL EVALUATION

APPENDIX 2.2

Basis of Cost Estimating for Model Evaluation

These estimates are based on published literature of general cost data for room and pilar mining methods (Cameron 1, Stram 2} Dravo3), and on a specially commis­sioned cost analysis prepared by the "Pace Company Consultants and Engineers"^ of Denver, modeled on the White River Shale Project U-a and U-b detailed development plan. All costs are simulated for January 1981 constant dollars, and they have been adjusted for the scale of operations at 50,000 barrels of refinery crude oil per day.

It must be emphasized that these costs have been developed purely for the purpose of demonstrating the evaluation methodology. While we believe they are probably of the right order, we do not recommend that they should be used as valid estimates for evaluation purposes, nor should the calculated land value of the demonstration model be taken as authoritative.

In order to meet the data input structure of the computer program, the estimates have been scheduled on a year-by-year basis under the following headings:

2.2.1. Preproduction capital and development costs

2.2.1. Direct operating costs

Mining

Retorting

Upgrading

2.2.3. Fixed annual costs

2.2.4. Working capital

The preparation of a definitive cost estimate for a real life shale oil facility would include a number of site or project-specific items not included in this analysis. They could represent major financial commitments materially affecting the viability of the project. These items include:

Acquisition of land and rights-of-way

Permit acqusition and process licensing

Research and development for mining and process­ing design

- 77 -

Off-site production transportation

Off-site roads

Off-site electric power lines

Off-site water supply (dams and pipelines)

Off-site employee housing and community facilities

2.2.1 Preproduction Capital and Development Costs

In this context, capital costs are defined as lump sum expenditures for the acquisition of certain types of property which qualify for depreciation, amortization, or depletion over a period of time. Development costs comprise preproduction expenditures on excavations and other essential preliminary work to bring the mine to the stage where it can support a continuous production of 93,000 tons of raw shale per day. It is important to clearly discriminate betwen capital and development costs because they are treated differently for tax purposes, as explained in Appendix 2.1.

2.2.1.1 Underground Mine

Figure A2.2.1 is a schematic diagram of a general underground mine layout adopted for this model. Raw shale is conveyed to surface up a 13- inclined conveyor belt shaft from a central undergound location in the mine, which will also be served by an 8 percent winding decline for handling ventilation shafts for fresh and exhaust air. This area will also accommodate underground maintenance workshops, the primary crusher station and ore-loading facilities, mine water settling sumps and pump chambers, and equipment marshalling and refueling facilities.

The movement of ventilating air, men, materials, and mined shale will be along a grid system of five parallel access entryways. Mining will advance from the central area outwards towards the boundaries, and twin ventilation shafts will be repeated at about 8,000-foot intervals to provide the quantity of fresh air necessitated by the diesel equipment.

Figure A2.2.2 is a schematic diagram of the mining panel layout (with acknowledgment to the White River Project DDP). Mining panels will be 1940 x 1050 feet with an average pay zone thickness of 60 feet mined in two cuts. Internal pillars 60 x 80 feet will support 60-foot wide rooms, leaving barrier pillars 80 feet wide, thus giving an overall resources extraction factor of 70 percent.

Figure A2.2-3 is a chart illustrating the preproduc-tion schedule of costs required to bring the mine to full-scale production within six years after receiving a lease allocation. Annual expenditures are identified as capital or development costs by entering the capital amounts at the start of the years concerned, and develop­ment costs at the end of the year. In addition, total costs for each category are summed for each year, and the total costs for each heading are summed for the preproduction period. The general basis of these esti­mates is outlined below:

2.2.1.2 Preliminary Administration and Engineering

This heading covers the early costs to meet environ­mental, permit, engineering, and contract prerequisites before actual construction work can commence. Two years is allowed for this work at a total cost of $10 million. No acquisition of property is included in this amount and it is therefore classed as a development cost.

2.2.1.3 Site Establishment

This category includes the physical construction and acquisition of property to establish site conditions suitable for construction work to commence. It includes temporary buildings, access roads, power and water reticulation, surface preparation and drainage, security, fencing, and related administration costs. A bulk estimate of $10 million is spread over three years as capital expenditure.

2.2.1.4 Inclined Belt Shaft

This estimate covers the entire capital and develop­ment cost to establish the ore transportation conveyor belt facility, including excavating the inclined shaft and ancillary openings, procurement and installation of the primary crushers, feeders, conveyor belts, surface tipping arrangements, and stock pile containment and draw points. A rough breakdown of the global estimate of $25 million is:

Development Costs:

Excavation of shaft and crusher stations $7 million

Capit-al Costs:

Excavation equipment (loading, drilling, hauling, support, dumping) 3 million

2.2.1.5 Men and Materials Decline

This estimate covers the entire capital and develop­ment cost to establish the men and materials handling facility between surface and underground. A rough breakdown of the global estimate of $12 million is:

Development Costs:

Excavation of decline $ 9 million

Capital Costs:

Excavation equipment (loading drilling, hauling, support, dumping) 3 million

$12 million

2.2.1.6 Ventilation Shafts

This estimate covers the entire capital and develop­ment costs to establish the fresh air and exhaust ventilation system, including sinking twin 16-foot diameter shafts, shaft bottom excavations to establish through ventilation, and the procurement and installation of the exhaust fan. The global esitmate of $6 million is made up as follows:

Development Costs:

Shaft sinking and excavations $ 2 million

Capital Costs:

Temporary hoists, headframes and sinking equipment, and exhaust fan 4 million

$ 6 million

Provision is made in the capital and development schedule to sink three additional twin shaft systems at intervals of 5 years after the start of production.

- 83 -

2.2.1.7 Development in Shaft Pillar

This estimate covers initial excavations to inter­connect all shaft facilities with the 5-entry mine layout. In addition, it includes the excavation of workshop space, mine water settlers and pump chambers, and other service facilities. The estimate of $7 million is classed as development work.

2.2.1.8 Conversion to Permanent Condition

This estimate of $2 million covers the capital costs to integrate all systems as a going concern mine. In particular, it includes the procurement and installation of water settling and pumping equipment, reticulation of electricity, communication and service facilities, safety devices, accident and health facili­ties, cap lamps, etc.

2.2.1.9 Mining Equipment Acquisition

Excavation and loading equipment required to . mine hedings, panels, and benches will remain constant over the life of the mine. In this model it is supposed that the mied shale will be transported from the excava­tion site to the primary curshers by a fleet of 100-ton rear dump trucks. As the mining areas advance toward the boundaries, it is clear that the number of haul trucks required will increase. Allowance is made in the capital schedule for such a buildup in unit requirements in addition to the replacement of working units at the end of their economic life, which is assumed to be 8 years for all underground mining equipment.

In the preproduction period, all loading and hauling will be done by 12-cubic yard LHD units. Provision is made for the initial acquisition of these units, but no replacement is envisaged as they will not be used under permanent mining conditions. It is estimated that the following major equipment items will be required to produce at the rate of 93,000 tons per day.

2.2.1.10 Buildings and Mine Service

This estimate of $2 million includes on-site mine buildings, such as offices, change houses, canteens, warehouse, garages, as well as general surface installa­tions associated with the mining operation.

2.2.1.11 General Administration

This bulk estimate of $17 million includes all administrative services associated with the preproduction construction period, such as contract management, scheduling, engineering, secretarial, environmental monitoring, etc.

2.2.1.12 Crude Shale Oil Production

This plant will include secondary crushing of raw shale drawn from the stockpile, retorting in three different types of retort, and spent shale disposal and revegetation. In addition, provision is made to generate sufficient electricity from excess flammable gas to meet the full requirements of the project.

Figure A2.2.4 illustrates the preproduction capital cost schedule to enable the surface retorting facility to handle a raw shale feed of 93,000 tons per day by the sixth year after lease allocation.

2.2.1.13 Secondary Crushing

Crushing produces a wide distribution of particle sizes. The vertical type retorts can only handle a size range of 3 inches to 1/2 inch — the minus 1/2 inch fraction is screened out to be treated in a special TOSCO type retort.

2.2.1.14 Retorting

Provision is made for three types of retort. Less energy efficient, indirectly-heated retorts are used to produce high Btu gas for feedstock for hydrogen production required in the upgrading plant; directly heated retorts are more energy efficient but produce low Btu gas which can be used for generating power; the minus 1/2 inch fines, which cannot be treated in vertical-type retorts, are processed in rotary grid, TOSCO-type retorts.

It is assumed that vertical retorts have a capacity of 11,500 tons per day for each module and operate at 95 percent of Fischer assay recovery. The TOSCO-type retorts have a capacity of 12,000 tons per day and operate at 100 percent of Fischer assay recovery.

Sufficient excess capacity is assumed for each type of retort to allow for continuity of operation when individual modules are out of service. This amounts to 5 D.H. retorts with 1 standby unit; 1 I.H. retort and 1 standby; 1 TOSCO-type retort and 1 standby unit.

2.2.1.15 Spent Shale Disposal

Processed shale is moved from the retorts to an on-site erosion valley for disposal. A 4,000-foot overland conveyor system moves the shale to the general site area; from there it is distributed by haul trucks and -graded and compacted using graders, bulldozers, compaction equipment, and water trucks. Irrigation pipelines and spray equipment are provided for revegeta-tion.

Provision is made for replacing mobile equipment after a useful life of 8 years.

2.2.1.16 Electric Generating Plant

A power station capable of generating 100 megawatts of electricity. to meet on-site usage represents a major investment cost subject to considerable uncertainty. It must operate on low Btu gas from the D.H. retorts, possibly augmented by heavy upgraded shale oil. The capital cost is conservatively estimated at $550/KW. The actual plant cost may be significantly higher depending on the quality of the low Btu gas.

2.2.1.17 General Surface Facilities

These facilities will serve the entire surface

- 87 -

plant complex, but for the sake of convenience, they are listed under the retort plant.

The surface buildings investment cost includes an allowance for administrative offices, plant and process control, laboratories, personnel amenities, first aid, pump stations, and maintenance workshops.

Water supply costs include an allowance to cover on-site reticulation, pump station, collection facilities from a surface stream, and a small storage reservoir.

General facilities include sewers, electrical distribution, communications, utility delivery systems, paving and yard work, plant security, fire equipment, and administrative equipment.

2.2.2. Direct Operating Costs

Direct operating costs are the day-to-day expendi­tures incurred in operating plant and equipment. They include the cost of labor, supervision, consumable supplies, services and routine maintenance and repairs. Not included are depreciation, taxation, interest, general plant insurance, and general administration.

All cost estimates are based on the premise that the entire project will be completely energy self-sufficient. No distributed charge is made for diesel fuel because the full cost of production is debited to the diesel distillation plant; electric power is charged to the various consumer centers at 0.7£ per KWhr., which merely covers the cost of operating the power station since the boiler fuel is produced on-site by the retorts; similarly, no charge is made for high Btu gas used in the upgrading section.

2.2.2.1. Underground Mining

Estimates for underground mining costs are based on USBM Contract Report No. S0241074, "A Technical and Economic Study of Candidate Underground Mining Systems for Deep, Thick Oil Shale Deposits," prepared by Cameron Engineers,4 July 1975. Table 4.28 of this report summarizes the estimated annual production cost for a 30.175 million tons per year advance entry and pillar mining method. These costs have been adjusted for scale of operation and simulated for 1981 constant dollars. In addition, the cost of electric power has been reduced to allow for on-site generation, and the cost of diesel fuel has been deducted. The adjusted costs are summarized below in 1981 constant dollars:

At 34 million tons per annum, cost per ton mined (first year) = 1.32

For this broad evaluation, operator efficiency is approximated by considering five hours of working time per eight-hour shift. The mine is designed on a two-shift seven days per week work schedule; and a working year is taken as 355 days to allow for holidays.

2.2.2.2 Retorting

Retorting costs are based on the Pace Company^ cost analysis, allowing for the fact that electric power is supplied at the cost of operating the power station on (0.7^/KWhr). These estimates are summarized below in 1981 constant dollars:

2.2.2.3 Upgrading to Refinery Crude Oil

While the upgrading processes are based on estab­lished oil refining technology, details specific to oil shale are currently ill defined. No attempt has been made to develop an integrated material and energy balance which would be required for detailed cost analysis; however, it is considered that the estimates are reasonable for each of the constituent processes itemized in Figure A2.2-5, subject to the following general plant qualifications:

The hydrotreaters are capable of operating under sufficiently severe conditions to produce a continuous output of 50,000 barrels per day of upgraded crude oil which can subsequently be used as conventional refinery feedstock.

The hydrogen generation plant recovers hydrogen from the high Btu gas produced by the TOSCO II and indirectly heated vertical retort: it also produces additional hydrogen via steam reforming of light hydrocarbons in these retort gas streams.

Naptha . produced via hydrocracking in the shale oil hydrotreater is subsequently processed

- 90 -

in a Naptha hydrotreater. This additional hydrotreating step is necessary to produce a product which can be processed in refinery catalytic reforming units.

A small-scale distillation unit is provided to recover sufficient diesel fuel to meet on-site requirements.

_ Prior to processing in the hydrogen generator plant, the high Btu retort gas and light-ends from the whole shale oil hydrotreater are processed in .two amine adsorption units for removal of HZS and C02- The H2S is subsequently converted to elemental sulfur.

Sour water streams from the retorts and hydro-treaters are processed in sour water strippers which produce ammonia as a by-product, and H^S2, which is routed to the sulphur recovery plant.

Upgrading costs are based on the Pace Company^ analysis. Electric power is costed at 0.7^/KWhr; high Btu gas and liquid hydrocarbon fuels are drawn from on-site processes at no cost. These estimates are summarized below in 1981 constant dollars:

Shale oil hydrotreating

At 18.25 million barrels of crude oil produced per annum, cost per barrel = $2.57/barrel

2.2.3. Fixed Annual Costs

A bulk estimate of $4 million per year is allowed to cover general administrative costs such as head office fees, engineering services, cost of sales,

- 91 -

legal fee, regulatory costs, research and development, secretarial and accounting services, etc.

2.2.4. Working Capital

Working capital of $30 million is estimated to cover three months normal operating costs; $10 million is provided in each of the third, fourth, and fifth years.

TAR SAND RESERVES - P.R. SPRING DEPOSIT, UINTAH AND GRAND COUNTIES, UTAH

by

JOHN M. DAHM Consulting Geologst

in association with

THE UTAH GEOLOGICAL AND MINERALS SURVEY

- 190 -

TAR SAND RESERVES - P. R. SPRING DEPOSIT, UINTAH AND GRAND COUNTIES, UTAH

by

John N. Dahm, Consulting Geologist

INTRODUCTION AND GEOLOGY

The P. R. Spring tar sand deposit is located in southeastern Uintah and north­

eastern Grand counties, Utah (Townships 11-17 South, Ranges 21-25 East). The

area lies in the southeastern corner of the Uinta Basin, adjacent to the Utah-Colorado

State line.

The regional dip in the area is gentle, generally 1-2° to the northwest. In the

northeastern part of the area, the dip steepens to about 3° and is more westerly,

reflecting the proximity of the north-south trending Douglas Creek Arch.

Map VI, Structure Map-Top of the Douglas Creek, indicates the lack of major

surface structure in the area. The main feature is the Hill Creek anticline which

transects the southwestern part of the area from northwest to southeast. Faulting

is minor, with the few faults present striking westerly and having small displacements.

Map VII, Surface Geology and Overburden Thicknesses, shows the contacts

of the three formations at the surface of the area. In ascending order, the

stratigraphic units are: the Wasatch Formation, the Douglas Creek Member of the

Green River Formation, and the Parachute Creek Member of the same formation.

The Wasatch Formation is exposed along the Roan Cliffs to the south. It also

appears in the deeper canyons of the northerly running major streams which cut

through the Douglas Creek Member.

The Douglas Creek Member has the major surface exposure whereas the over­

lying Parachute Creek Member is confined to a broad arc which swings around

from the southwest through the north to the northeast. The Parachute Creek is

intricately dissected and has left behind a number of remnants (outliers) in its

northerly retreat.

- 191 -

The tar sands or oil-impregnated sandstones (OISS) are the major resource

in the area. They are found in the lower part of the Parachute Creek and the

upper part of the Douglas Creek. Locally, there is minor interbedded oil shale.

The foregoing geologic description is abstracted from the following authors,

and it is recommended that their publications be consulted for greater detail:

Cashion (1967), Byrd (1970), Gwynn (1971), Peterson and Ritzraa (1974), and

Peterson (1975).

OBJECTIVES

The primary purpose of this investigation was to determine the total reserves

of the P. R. Spring tar sands under State lands. The quantity as well as the

lateral and vertical distribution thereof are necessary for a variety of State planning

procedures. Specifically, the State Land Board can use this reserve data to guide

leasing procedures.

SCOPE

This investigation was not designed to be an exhaustive study of the geology

of the area. Rather the intent was to generate the following data as expeditiously

as possible:

1. Total reserves of OISS (proven, probable, and possible).

2. Vertical and lateral distribution of these reserves.

3. Certain other data which should be useful as development proceeds,

such as:

-zonation

-depths and elevations

-thicknesses (gross and net)

-lithologies

-physical characteristics of the oil.

-barrels of oil per acre-foot and per section

-tons and cubic yards of OISS

-overburden and interburden data.

- 192 -

PROCEDURE

The investigation proceeded through a number of data gathering phases as

follows:

Phase 1 consisted of preparing a new reproducible base map from an existing

UGMS reproducible base map. The control points (core holes and measured sections)

were plotted on the base map as well as the strat igraphic contacts.

Phase 2 was concerned with a tentative zonation and correlation grid of the

13 UGMS core holes and the four (4) Skyline Oil Corp. core holes.

Phase 3 carried the above zonations and correlation into the strat igraphic

sections measured by Byrd (1970). Phases 2 and 3 were based on previous work

by Byrd (1970), Gwynn (1971), Peterson and Ritzma (1974), and Peterson (1975).

These two phases established the basic geometry of the tar sand deposits and form

the foundation of the entire s tudy .

Phase 4 consisted of drawing the following maps:

Map I, Isopach Map - Zone A, Net Pay

Map I I ,

Map HI ,

Map IV,

Map V,

Map VI, S t ruc ture Map - Top Douglas Creek

Map VII, Surface Geology and Overburden Map

Maps VI & VII were based on Cashion's map. See Cashion (1967).

Phase 5 was the modeling and filling out of the 8£ x 11 inch data sheets (example

at tached). The data generated are listed in SCOPE under item 3.

Phase 6 was the compilation of the State reserve data by land grid (section,

township, and range) and by zones. An abbreviated summary follows under RESERVES

DATA-DISCUSSION AND INTERPRETATION

Phase 1 (base map). It is important to note that most of the measured sections,

" B , "

" C, "

" D, "

" E, "

- 193 -

from 27-38, have inexact locations (to the nearest quar ter sect ion). These non­

specific locations introduce e r rors into the isopach maps.

Phases 2 and 3 (zonation and correlation). It is emphasized that the zonation

and correlations of the OISS zones are provisional. They are based, largely, on

distinctive algal, ostracodal, or cblitic limestones and colitic sandstones which often

bound the OISS.

Much additional control (core holes and surface sections) is needed to firm up

these correlations. Full suites of mechanical logs (electrical, gamma- ray /neutron/

density, etc.) should be run in future core holes to improve these correlations and to

supply other needed data.

Phage 4 (maps). Concerning the maps, there are a number of cautions and

observations.

The isopach lines (Maps I-V) are dashed ra ther than solid due to the inexact

locations of certain measured sections discussed under Phase 1, and due to the lack

of control points in much of the area . Thus , many of the isopach lines are inferred

and subject to differing interpretat ions.

The net effect of the foregoing is that the bulk of the reserves is in the

probable and possible category, ra ther than the proven category. There will need

to be many more core holes and surface sections in order to firm up the reserve

estimates. This additional control will result in substantial lateral shifts from the

possible-probable categories to the probable-proven end of the spectrum.

It should be mentioned that no isopach map of the F Zone net pay has been

made due to lack of information on its upper limit and distribution. Net pays are

shown on the data sheets of the control points; and the probable and possible

reserves should be significant, though highly dissected and often deep.

Map VI, Structure Map, Top Douglas Creek, is only approximate and should

not be used for detailed work. Sources of error are changes in map scale, the

- 194 -

generally wide spacing of the control points., and the extreme lack of control where

the Douglas Creek is exposed at the surface and eroded.

Additionally, measured sections 27-38 have no elevation control and the

elevations of many of the rest of the sections were measured by aneroid barometer

and are of insufficient accuracy for structure mapping.

Map VII, Surface Geology and Overburden Map. A detailed overburden map

and interburden maps were not drawn due to insufficient hard data. As more control

becomes available and as areas suitable for surface mining become better defined, it

will be possible to compile localized cover maps.

Overburden thicknesses to the uppermost tar sand are shown at the control

points. Additionally, best estimates have been made of the overburden thickness

to the top of the Douglas Creek (top E Zone) in certain sections which have the

Parachute Creek at the surface. These numbers are approximate only.

Map VII indicates that roughly one-half of the P. R. Spring area has Douglas

Creek at the surface. Further, there are broad exposures of Zone E with OISS

within 50 feet of the surface.

The other one-half of the P. R. Spring area has highly dissected Parachute

Creek at the surface. Generally, depths to the F and lower OISS, here, are

greater than those in the area where the Douglas Creek is at the surface.

Depths to the E Zone under Parachute Creek cover are in the 200-400 foot

or more range in the northeast (T.12 S . , R.24, 25 E.) and in the southwest

(T.17 S . , R.21, 22 E . ) . In the area between, the depth to the E Zone i s , generally,

in the 100-200 foot range.

Phase 5 (data sheets) . The following explanations and sources of the data

will aid in their use (See page 1 of attached data form).

Elevations. Two are given for each control point. The Average Elevation is

a quick estimate of the entire section from USGS topographic sheets.

- 195 -

Net Pay in Zone. In the control points, this is the accumulative amount down

to a one foot minimum, regardless of the apparent degree of saturation (whether very

weak or very rich). The pay is often non-continuous and may occur anywhere

within the zone. In the data sheets from the sections without control, the minimum

net pay is five (5) feet (one-half a contour interval on the isopach maps).

The degree of saturation (visual estimate) is from the cores, and the gravity

(°API), and percent sulfur are from the Core Lab core analyses.

On page 2 of the data form, under Resource Evaluation, several explanations

are in order:

The barrels per acre-foot (bbl/ac.-ft) for the USGS core holes and SKL-79

are calculated as follows:

Bbl/ac.ft . =oil volume (bbl) acres x net pay

The acreage unit is one full section (640 a c ) , except in T.15-£ S . , where it

is 320 acres (fractional township and sections therein).

For the State sections, without control, the barrels per acre-foot are assumed

from zonal averages calculated for the core holes as shown above. The reserve,

gross barrels of oil (bbl, gross) , is calculated as follows: (100%'recovery assumed).. 2

Bbl (gross) = net pay (ft) x 640 (ac/mi. ) x bbl . /ac . f t .

The stripping ratio on p. 2 of the data sheets is the quotient of the ratio of

the overburden down to the first pay divided by that net pay.

The basic data for this report is found in the 8-fc x 11 inch data sheets and

in the large green data sheets on file. In cases of conflict of data, the 8£ x 11 inch

data forms should be assumed as correct.

The APPENDIX (attached) gives the formulas used for calculating the percent

of oil saturation by weight and the tons of OISS. These may be useful as

development proceeds in the future.

RESERVES

The total reserves on State land of the P. R. Spring area have been compiled

from the data sheets and are shown in an abbreviated form below. The reserves

are based on data from the core holes, the measured sections, and the isopach maps.

These reserves are a best estimate of the presently known total resource . They

include the widely used classifications of proven (or measured), probable (or indicated)

and possible (or infer red) .

townships, contain the bulk of the reserves (73%) and, generally, are the highest

in bar re ls /acre .

The average barre ls /acre for all the above townships is 37,700, including the

above-mentioned "rich" townships. The average ba r re l s / ac re , excluding the "rich"

townships, is 27,400, and the average barre ls /acre of the "rich" townships only is

The 50,430 gross State acres are equal to 79 square miles, approximately.

This would be equivalent to an area of about eight by ten miles square . The gross

State acres have been reduced to an estimated 47,280 net acres , a 6% reduction,

due to the following: a) erosion along the Roan Cliffs and in the deeper canyons

of the major northerly flowing streams has cut through and removed the tar sands,

and b) where the O isopach line passes through a State section, the State land is

reduced accordingly. This would be termed a (lateral) pinchout.

The F Zone reserves are considerably greater than herein shown, even though

the zone is severely dissected by erosion. As previously discussed, no isopach

map was made of this zone due to insufficient data. Thus , only the reserves for

the measured sections in T.17 S . , R .21 , 22 E. are shown. The zone needs more

study particularly on the placement of the upper boundary.

SUMMARY, CONCLUSIONS, AND RECOMMENDATIONS

The OISS are found in the lower par t of the Parachute Creek and the upper

par t of the Douglas Creek. Locally, there are minor amounts of oil shale.

The zonation and correlation of the OISS zones is based, largely, on distinctive

algal, ostracodal, and oolitic limestones and oolitic sandstones. The zonation and

correlation of the zones is provisional and will be modified, undoubtedly, as control

in the area increases.

Extensive additional control (core holes and surface sections) is needed to

pinpoint the best areas for future development and to firm up the r e se rves .

It is recommended that a full suite of geophysical logs be run on future core

holes to facilitate the zonation and correlation, and to supply other needed data.

The F Zone needs additional work so that an isopach map may be made and

additional reserves assigned. The main task , here , is determining a consistent

upper limit.

The estimated total reserves of oil (proven, probable, possible) in P. R. Spring

of 1.90 billion barrels are particularly significant in that they involve State lands

only. The Federal reserves are not included, nor are the interbedded oil shales.

- 198 -

At present , there are seven (7) contiguous townships in the south-central

part of the area that have the bulk of the reserves (73%). These are T.14 S . ,

R.22 E . , T.15, 15i S... 16 S.„ R.22, 23 E.

OIL SHALE AND TAR SAND DEPOSITS ON UTAH STATE OWNED LANDS

A table has been compiled of range, township and section number for

Utah State owned lands which show occurrences of oil shale deposits. A

similar table has been compiled for Utah State owned lands where tar sand

occurrences are found. The table for oil shale has been obtained from

information shown on the Energy Resources Map of Utah (Map 36) prepared by

the Utah Geological and Mineral Survey dated March 1, 1975. This resource

information was combined with land ownership data provided by quadrangle

surface management maps and a Utah State Land Status Map obtained from the

U. S. Bureau of Land Management. These latter maps were published in 1975

and 1977. The information on tar sand occurrences was obtained from the

same land ownership maps and Oil Impregnated Rock Deposits of Utah (Map 47)

prepared by the Utah Geological and Mineral Survey, published in January 1979.

Changes in land ownership since publication of the BLM surface management

maps could result in changes in the tables.
