Intellectual Capital

Intellectual Capital is an important component in developing tight gas. Because each and every tight-gas asset is unique, that is,no two are exactly alike, each requires a new investigation to optimize development. The amount of experience a service providerhas in developing tight-gas assets is an indicator of that company’s capability in evaluating these reservoirs and their ability toquickly identify the most appropriate methods needed to optimize development. In this chapter, we review the industry awards,technical papers, and patents that comprise Halliburton’s Intellectual Capital in tight-gas development. Many customers come toHalliburton for innovative solutions after other service providers have failed, leaving tight-gas fields uneconomic or unproductive.Developing and producing tight-gas reservoirs is not easy, or straightforward, and technical innovation is an essential element inachieving economic success.

In the first section of this chapter, we present the industry awards presented to Halliburton over the past five years. These awardsrepresent customer affirmation that the technological solutions are significant and leading edge. Halliburton has consistently won technical awards, year after year, for solutions in this area. Although some award descriptions may not specify a particulartight-gas field, this solution has, and can be applied to tight-gas reservoirs.

In the second section, we present the primary method of technology transfer: published technical papers. These papers discuss both the theory underlying a particular technique or technology and also present case histories describing the practicalapplication of these technologies. This section contains a list of Halliburton tight-gas-related technical papers, organized by the tight-gas challenges they address, that were published over the past five years. Due to limited space, only the SPE papers arelisted here. Needless to say, there have been many other articles published by other technical societies and publishing houses.

In the last section, Halliburton’s patents related to tight-gas development are also organized by the challenge they solve.Halliburton’s global technology research organization supports all nine of of the company’s product service lines and hasspecifically targeted research and development for the tight-gas market.

Awards

Hart’s E&P Meritorious Engineering AwardsIn the past five years, Halliburton has won more than twice the number of Hart’s E&P awards than our competitors. In this section, we focus on the technological solutions receiving awards applicable to tight gas.

2009 Award: Intelligent Systems and ComponentsSolution: Landmark’s Pore Pressure and Geomechanics Solution

The Landmark Pore Pressure and Geomechanics system helps operators worldwide achieve new levels of risk reduction, costsavings, and drilling performance – significantly enhancing profitability while helping to ensure personnel and environmentalsafety. During the Subsalt Joint Industry Project (an extension of the DEA 119 study) conducted from 2005 to 2007 with twelveoperators, the system’s new technology was developed and tested to manage the challenges of drilling near and below salt. Thestudy modeled the Mahogany, Tahiti, and Typhoon subsalt basins in the Gulf of Mexico and confirmed the functionality, accuracyand usefulness of the technology.

Over the past two years, commercial applications on wells ranging from Malaysia to the Gulf of Mexico, have demonstrated thesystem’s innovative pressure-ahead-of-the-bit provides highly accurate real-time updates, 80% are within 0.5 lbm/gal and 90%within 1.0 lbm/gal, as much as 2,000+ ft ahead of the bit.

This technology has helped operators like Jubilant Energy in India turn around multiwell exploration programs that were plagued bytrouble, such as overgauged holes and well failure. An improved understanding of the wellbore environment helped reduce drillingtimes by a third and significantly lowered overall well costs in a multiwell drilling program. In a four-well test program using thissolution, no NPT was experienced on two of the first three wells and a casing string was eliminated in the fourth, resulting insubstantial savings. After gaining experience implementing the solution, Jubilant Energy was able to cut well costs nearly in half,from $6 million in the first well, to $3.7 million in the fourth well, in onshore drilling programs with little margin for error.

In another example using this solution, a major operator in Europe developed a new workflow for real-time analysis. Theoperator’s head offices streamed real-time data directly into Pressworks™ software and used Drillworks® applications to perform real-time geopressure and geomechanics analysis. A company representative noted that the Drillworks application,which is certified for WITSML, was the only solution he had been able to setup with WITSML within 40 min, and which thenworked correctly. An administrator at the operator has called the system critical to their drilling operations, and it is being used toproactively monitor wells to help prevent costly problems and safety incidents.

A major operator in the Middle East utilized the system with consulting services. In a difficult geological regime wherepetrophysical approaches fail, due to thepresence of carbonates, analysts were able touse hydrodynamic modeling and integratedwellbore-stability analysis to more accurately predict pore pressures and preventborehole-stability problems. The analystsremotely monitored eight fields in real timeand in the first 30 days, and thereafter, wereable to help the operator significantly reduceNPT due to stuck pipe and lost circulation.They were also able to shorten overall drill time in the first 30 days, and thereafter.

In addition, the operator did not experience any safety incidents on these wells. The operator is now deploying the full solution in its real-time centers. The solution has proven highly effective worldwide to help operators increase safety and improve drilling success.

2009 Award: CompletionSolution: Delta Stim® Completion Service

To date, the Delta Stim® completion service has been utilized to isolate and treat over 1,500 zones in 250 different wellboreslocated throughout the USA and Canada. Total average pump time for each zone was 2.5 hr. Total time saved was approximately5,800 hr. With increased operational efficiency, this service also decreases the exposure risks for both the equipment andpersonnel associated with the well-completion process. This technology is now in use in North America, Europe, Asia and South America, where operators are looking for fast and efficient ways to complete newly drilled gas wells. Halliburton continuesto lead the industry in the development of new tools and services that will be used to enhance the future capabilities of the Delta Stim completion service, such as zonal isolation using cement with improved wiper-plug performance, improved hydraulic-set openhole packers and new techniques for using swellable elastomer packers. Delta Stim completion service allows the stimulation to be placed in the optimum location for best production results. Please refer to Chapter IV for a moredetailed description of the technology.

2009 Award: StimulationSolution: Acid on-the-Fly Blending System

Application of acid on-the-fly (AOF) is prevalent in the Elk Hills Field, near Bakersfield, California. This field is the seventhlargest in the continental United States, with cumulative production exceeding 1 billion barrels of oil and 1 Tcf of natural gas. The Elk Hills field has many complex reservoirs, some of which require acid stimulation to achieve commercial viability. However,because of the extremely large acid volumes and variable injection rates required, conveying the acid treatment by conventionalmethods was a logistical challenge. Accurate delivery of the acid treatment was further complicated by uncertainty in the fluidplacement, the presence of thief zones, and natural-fracture swarms that frequently could not be located precisely until the actualtreatment was in progress. AOF has been used in oil reservoirs and can be applied in tight-gas reservoirs, as well.

Before the advent of AOF technology, execution of a typical 60,000-gal acidizing service with 12% HCL/3% HF, involved morethan 15 round trips between the acid-blending facility and the job site, at least five dedicated drivers, at least seven dedicatedcrewmen for blending and transferring product, and six deliveries of raw product from vendors. Before development of the AOF blending system, preblended acid product was moved and processed several times. It was common to use 20 to 30 poly tanks (6,000 gal capacity each) on a single job. At the end of each job, there was typically 80 to 100 gal of residual acid left in eachtank which had to be vacuumed out anddisposed of. This added an extra cost tothose already incurred in mobilizing andrenting the tanks.

This blend-and-batch method affected thecapacity to perform multiple jobs, becauseit tied up employees and equipment on a single job for several days. Oneoperating company alone averaged 30 jobsper month and used over 1 million galblended acid per month. In contrast, theAOF blender system/process with its on-the-fly acid delivery, is inherently moreefficient than the blend-and-batch acidizingmethod using one operator. Raw materialsare delivered to the wellsite and blended at the point of use, then consumed immediately; most unused chemicals are restocked orused on the next well. On a recent job, the monitoring service showed that an acidizing treatment was completed at around 75%of the total amount estimated per the original job design, resulting in a more effective treatment and a 25% material-cost savingsfor the operator. Mixing on the fly enabled early cessation of the treatment, with minimal waste of material.

It is estimated that the AOF blender and process significantly increases operational efficiency, resulting in 20–40% increase in jobs completed due to greatly reduced setup time. Reducing the transportation, handling and storage activities required toblend acid with conventional methods creates a potential savings of as much as 50% on chemical delivery charges, includingdriver/operator costs. By minimizing employee exposure to acid and virtually eliminating the need to dispose of unused acid, theAOF system helps to greatly improve HSE aspects of acid treatments.

2008 Award: Intelligent Systems and ComponentsSolution: Swellpacker® Cable System

The Swellpacker® cable system has enabled the world’s first openhole SmartWell® completion system to be deployed successfullyin the Middle East. This resulted in a significant reduction in well construction costs for the operator.

The operator’s first intelligent well completions were drilled as 7-in. fullbore wells. The cemented 7-in. liner was placed below theconventional 9-5/8-in. casing and provided the lateral isolation between Level-two multilaterals drilled out of the 7-in. liner.Standard 3-1/2-in. interval control valves and mechanical packers were used to provide the required intelligent well completioninside the 7-in. liner.

The operator now wanted to reduce well costs and increase reliability. The operator decided to change the completion method byrunning openhole intelligent completions in the 6-1/8-in. open holes with the Swellpacker cable system for zonal isolationbetween the openhole laterals. Utilizing the Swellpacker cable system eliminated the need for the 7-in. liner, cementing the liner,and all of its associated rig time and costs. The control-line feed-through feature of the Swellpacker cable systems increasedreliability by eliminating splices in the control line above and below the packers, reducing the risk of control-line leaks.

Installation of the control line into the Swellpacker cable systems was easily performed in a matter of minutes versus several hourswith the conventional method that requires splicing each set of cables—significantly reducing rig time. To date, two openholelateral wells have been completed by this operator with intelligent completion and Swellpacker cable systems. The review of theproduction and pressure data from these wells showed that the Swellpacker cable systems provided lateral isolation, and theintegrity of the lines has been maintained. This success has helped ensure that several future wells will be completed as openholelaterals with intelligent completions and Swellpacker cable systems for zonal isolation.

2008 Award: Drilling FluidsSolution: INTEGRADE® Diesel-based System

INTEGRADE® diesel-based system helped an operator save $104,000 by eliminating downhole losses on a slimhole reentry well in Webb County, Texas. The operator planned to drill a deep slimhole well in an area where all the offset wells hadexperienced significant mud losses. Reducing the equivalent circulating density (ECD) would be a critical factor in minimizinglosses while drilling the deviated slimhole reentry well (62° maximum angle). The formation integrity test at the casing shoe was 17.1 lbm/gal, but the operator anticipated encountering the depleted Lobo sands that are typical of wells in the area. Baroid recommended drilling the well with the INTEGRADE system, which was proven to help minimize mud losses, reduce ECD and improve hole cleaning characteristics.

For a description of the INTEGRADE or casing while drilling system, please refer to Chapter IV.

INTEGRADE® Diesel-Based System

Using a 15.3 lbm/gal INTEGRADE® system, the 4-1/4-in. well was drilled to 12,416 ft with zero mud loss. In contrast, an average of 1,178 bbl oil-based fluid was lost on three offset wells where a conventional system was used, including one slimholewell and two wells with 6-1/2-in. production intervals. Using the INTEGRADE system helped the operator save $104,253 on thiswell, and a credit was issued for over 200 bbl of fluid returned at the end of the well. The customer’s drilling engineer for thisproject has continued to use the INTEGRADE system consistently on subsequent wells in this area. Chosen by several major andindependent operators for its drilling performance and reduced downhole losses, INTEGRADE fluid has been used successfullyon conventional and HPHT wells and has been implemented very extensively in casing-while-drilling operations. While drillingthe 3,760-ft interval, the operator encountered depleted sands with formation pressures of 3.0 to 5.0 lbm/ft equivalent mudweight (EMW).

2008 Award: Formation EvaluationSolution: InSite ADR™ Azimuthal Deep Resistivity Sensor

Unconventional gas reservoirs operators utilize the InSite ADR™sensor to find the best sweetspots in multilayered reservoirs.

A European customer in the North Sea needed to drill in a thin, heterogeneous reservoir bordered by potentially unstable formations.The customer desired to avoid these unstable formations at all costs,due to the increased risk of borehole collapse and the potential loss ofthe reservoir section. This concern is typical in drilling older fields,where past production has weakened shallower formations. This isalso a concern in drilling the European stratigraphic section, due to its geological complexity. Until now, there was no reliable way ofdetecting the unstable formations until the drillbit penetrated them.The customer realized that the InSite ADR sensor could helpoptimize wellbore placement and maximize production.

The InSite ADR sensor enabled the customer to stay in the reservoirand identify the “sweetspot.” Once identified, the customer was able to stay in the sweetspot by steering the well with real-timeresistivity measurements transmitted to surface from the InSite ADRsensor. The new information gathered by the InSite ADR sensorprovided much higher-resolution input data to the earth model forthe area around the well, which will allow future well planning topinpoint remaining reserves.

2007 Award: DrillingSolution: AssetPlanner™ Software

One of the industry’s largest energy companies used AssetPlanner™ software to evaluate early-field development options in ashallow offshore area with seabed-slope instability and mud-volcano hazards. The objective was to select reservoir targets, identify viable drilling locations, create well paths that meet pore- and fracture-pressure constraints, determine drilling costs based on an existing cost model and present development concepts to partners.

The case history below was used in the award. The technology is directly applicable to tight-gas assets as described in Chapters III, IV and V.

Utilizing seabed topography, shallow hazard data, 3D seismic, overburden pressure models and 3D model surfaces, amultidiscipline team set up the model in two days using AssetPlanner software. Working collaboratively, they createddevelopment scenarios that met their constraints in less than two hours. Results were quality-controlled in another four hours,and the team delivered reservoir targets, well trajectories, drilling locations, 3D images, and development well costs to partnersthe very same day.

“AssetPlanner software is an efficient solution for the screening of development drilling concepts,” concluded the team’s drillingengineer. “We did in one day what could have taken a month of crossdiscipline iterations and data transfer.”

AssetPlanner and AssetView™ applications are presented in Chapters III and IV.

2007 Award: Wellbore ConstructionSolution: Cement Assurance® Tool

To help ensure success for intelligent completions to be installed in two multilateral wells, an IOC needed effective zonal isolation between the lateral junctions. The main issue was the prospect of mud channeling occurring during cement placement,particularly in the highly deviated or horizontal sections of the well. Mud channeling is caused by the casing sitting eccentricallyin the open hole, allowing channels to form on the low side of the hole, usually at either side of the casing. This can result in inter-zonal communication behind the casing string.

To solve the problems of mud channeling and help ensure an effective annular seal below the lateral junctions, the IOC installed the Swellpacker® Cement Assurance® tool as part of the casing string, sealing off the mud channels and microannuli at thecement/casing interface. It also acts as a solid centralizer when run with the casing string and sits on the low side of the holewhere mud channeling normally occurs. The cement slurry is then placed conventionally behind the casing, cementing theSwellpacker system in place. After cement placement, the Swellpacker system swells to seal off any mud channels that werecreated, or microannuli that were generated by hydrocarbon flow along the channel.

The 9-5/8-in. casing, complete with two Swellpacker systems, was run, and the cement job was completed without any problemsthe first time. A cement-bond log was run after cement placement and confirmed that the Swellpacker systems had been placedcorrectly below each lateral junction. It also identified areas of bad cement. Installing the Swellpacker Cement Assurance toolsprovided effective zonal isolation between the laterals and helped to ensure the long-term success of the internal intelligentcompletion (with no extra rig time taken up installing the casing or pumping the cement job).

For more information on the Cement Assurance tool, please refer to Chapter IV.

2006 Award: CompletionsSolution: Swellpacker® Isolation System

The Swellpacker® isolation system is a packer that uses the swelling properties of rubber in hydrocarbon. The Swellpacker systemwill swell to expand and seal the annulus around the pipe either in an open-or cased-hole application. The system provides asingle one-trip solution for effective zonal isolation in the well completion and construction process. It has no moving parts andrequires no downhole or surface activation. Its simplicity, reliability and effectiveness as a complete zonal-isolation solution hashelped operators realize significant savings in well-construction costs.

Traditional cementing and selective perforating techniques are expensive and often fail across multilayered formations. While thiscase study is about high gas/oil/water operation, it is also applicable to tight-gas/water operations A major operator in Malaysiawas challenged with the problem of zonal isolation failures on its Sabah field, which not only increased total well constructioncosts but also reduced the well’s overall performance. Their reservoirs comprised multilayered, marginal, thin sands, with gas- or water-bearing sands in between, and were traditionally completed with a 7-in. cemented liner that was selectively perforatedacross the individual hydrocarbon-bearing sands. The operator would experience high gas/oil ratio or excess water productiondue to interzonal communication. The challenge was to find a more effective zonal-isolation technique and eliminate thecementing and perforating process to reduce well-construction costs.

The solution developed through collaboration between the operator and Halliburton, consisted of a string of up to ten Swellpackersystems, spaced out between the perforated and blank pipe. The perforated pipe was spaced out across the oil-bearing sands, withblank pipe across the gas or water sands. A Swellpacker system was run below and above each oil sand, isolating it from the wateror gas sand. This completion string was then run in a single trip and set with a normal production packer inside the previous 9-5/8-in. casing. The well was then put on production. The new completion assembly reduced the complexity of the operation andeffectively replaced the cementing of the 7-in. liner and subsequent perforating and completion operations. Significant savingswere achieved through reduced rig time and the elimination of cementing operations, liner materials, perforating runs, scraperruns, packers and completion equipment.

Total isolation was achieved in the two wells completed to date. Well construction costs have been reduced by more than 30%,compared with the average offset well. Further cost reductions are expected on subsequent wells. In the first case, total isolation of the intermediate gas sands was achieved with a lower GOR and higher oil-production rate, compared with offset wells. In the second case, intermediate water sands were sealed off completely after approximately seven days. The well was initially put on production with a 95% water cut, which dropped to 0% during the activation phase of the Swellpacker systems. This verified complete zonal isolation, and demonstrates the Swellpacker system’s ability to swell in high-water-cut environments during early production.

Swellpacker systems are also used in tight-gas completions. A case history ispresented in Chapter V, and the technologyis discussed further in Chapter IV.

2006 Award: ProductionSolution: StimWatch® Stimulation Montoring Service

A California operator planned a stimulation treatment for a well that was perforated in multiple tight-sands and shales. The upper perforations were depleted, whereas the lower, new perforations were normally pressured. Halliburton recommended a multistage sandstone acid treatment with diverter. To understand the performance of the diverter and monitor treatment of allzones, a retrievable OptoLog® DTS fiber-optic system was included as part of the acid stimulation. The StimWatch® monitoringservice allowed the operator to view the placement of the acid treatment in real time and to make instantaneous changes in thestage size and pump-rate.

Fig. 1 represents the actual temperature profile midway through the stimulation treatment. Wellbore temperature is plotted as afunction of depth along the entire wellbore. An expanded view of the perforated interval is shown below. The pink curve is the geothermal gradient, the blue curves represent the wellbore temperature at three timed steps midway through the treatment, andthe brown curve is the temperature profile at shut-in, after the treatment. Note that at this point in the treatment, the lowermostset of perforations is not being stimulated. A change in the diversion program was instituted allowing effective stimulation of thelowermost interval as is evidenced by the final temperature profile (brown).

2006 Award: Formation Tool EvaluationSolution: Hostile Sequential Formation Tester (HSFT™) Tool

The HSFT™ tool was introduced in the Gulf of Thailand three years ago and, to date, more than 300 successful runs have beenperformed without a single stuck tool or fishing. These jobs cover a range of well types that includes exploratory/delineation,initial platform development, and infill development oil and gas wells. Over half the wells logged exceed 350°F, and all have beendrilled with a synthetic oil-based drilling mud. Well deviations can reach 65°, and infill wells often encounter highly depletedzones. The combination of slimhole design and the surface-controlled, releasable cablehead have allowed unparalleled success inhole access for wireline conveyance. In the past, using traditional larger-diameter formation-tester tools, stuck tools and costlyfishing jobs were an inherent risk throughout the industry.

During the first three quarters of 2005, there were 117 wells logged with the HSFT tool in the Gulf of Thailand. The tool measuredvalid formation pressures on over 3,300 pressure tests and collected 58 fluid samples. Fewer than 3% of the total attempted setsfailed due to lost seals, and none were due to catastrophic pad failure. In the same period, the maximum recorded temperaturewas 385°F; and the HSFT tool operating-time efficiency was 97.3%. These statistics demonstrate that this technology has movedwell beyond testing into mainstream operation in hostile logging environments.

In addition to the Gulf of Thailand, the HSFT tool formation tester, along with the complete Hostile Formation Suite, is runfrequently in South Texas tight-gas reservoirs to define high-temperature tight-formation reservoir characteristics.

The HSFT tool demonstrated unprecedented performance in the Gulf of Thailand where slimhole hostile logging tools are used exclusively.

World Oil Awards

2008 Award: Best Data ManagementSolution: OpenWorks® Project Management System

The OpenWorks® project data management system aids the industry in producing faster, more accurate well locations by allowing asset teams to effectively manage, access and analyze their project data. The OpenWorks system stores key well and subsurface information and makes it accessible to interpretation and engineering applications required for exploration and well-planning workflows.

One of industry’s greatest challenges over the next few years is to manage the enormous loss of experienced personnel throughemployee retirement, estimated at 40% over the next ten years. The technology used in all components of the value chain, fromexploration and production to transportation, must improve to meet the anticipated increases in the demand for hydrocarbons.

One technology that has improved our ability to find hydrocarbons, the first part of the value chain, is the OpenWorks R5000database software. The OpenWorks application has been the most trusted project database in the industry for the past twentyyears. In the OpenWorks R5000 release, Landmark is enhancing this technology with four significant innovations:

• Knowledge capture• Traceability of data• Integration of prestack seismic data• Data optimization

Conventional data management solutions simply store data, without addressing two industry concerns – the need to capture and preserve project-specific knowledge and a history. The OpenWorks R5000 software allows an organization to capture the accumulated knowledge of its aging workforce. While some organizations may have knowledge management built into theirlinear workflows, the OpenWorks R5000 offers the opportunity to capture E&P knowledge directly in the interpretation workflow.Interpreters attach comments, documentation and links to resources in “notes” that are captured in the database, propagated to other applications and shared among the asset team. This provides new and inexperienced staff with access to critical project-

related knowledge, decisions, justifications,versioning, tips, etc. in the project environment.

Further, the OpenWorks R5000 release capturesmetadata, or data about data. This history helpsjustify and explain decisions that were made, whenthey were made, by whom, etc. to provide employeeswith the background to understand the “big” picture.This technology also helps organizations meet HSEand reporting requirements.

Existing project databases reference prestack andpost-stack seismic data inefficiently. Integration ofthese data types into the OpenWorks R5000 datamodel enable their use directly in subsurface

Prestack seismic becomes a native,managed data type.

OpenWorks® Project Data Management System continued

interpretation applications. This translates into time savings and an improved understanding of risks. Access to prestack dataoffers interpreters the ability to make better decisions, because stacking often smears data, making it more difficult to interpret.

Lastly, the OpenWorks R5000 software has resolved traditional data duplication issues through four enhancements. First, theproject database now comprises all of the shared data around an asset rather than a single project. Second, changes to the project

database are now shared dynamically with theinterpretation project rather than as copies. Third,cartographic conversion is done on the fly. There is noneed to save separate copies of the project in differentcartographic systems. Fourth, a more flexible securitymodel eliminates the need to create separate data setsfor partners, joint ventures, etc. These changes result indata optimization through reduced data duplication,improved accuracy and overall project and datamanageability. One customer estimates that data clean-up, together with these enhancements, will reduce itsproject data sets from 300 to 10.

The technical attributes of the OpenWorks R5000application translates to optimized asset teamperformance. Because knowledge and history areshared, individuals understand why decisions were

made, what considerations or risks exist, and new staff can ramp up quickly. Prestackseismic data are available directly to interpretation applications, saving time in analysis,reducing risk and achieving more reliable results. Lastly, by reducing data duplication,teams can find and use data more efficiently.

There are four significant economic gains: accelerated staff ramp-up time through thesharing of expert knowledge and processing history; more accurate well placement,through integration of prestack seismic data, reducing nonproductive drilling time;mitigated risk, through better decisions based on quality data; and IT operationalsavings, resulting from fewer data sets to manage, maintain and synchronize.

Finally, as our industry trains new professionals to exploit existing assets and find new reservoirs, accomplishing this quickly, efficiently, effectively and safely will depend on their level of knowledge, understanding and practical experience. The moreknowledge and experience we can impart, the more we can reduce the risks involved. The OpenWorks R5000 application helps ensure that this expertise and knowledge arepassed on to future workforce generations.

World Oil Awards

2008 Award: Best FluidsSolution: OmegaFrac® Fracturing Service

Halliburton’s OmegaFrac® fracturing service uses a biopolymer-based, linear (no crosslink required) fluid system as a carrier, which eliminates the need for hydrocarbon-based concentrates. Because the system does not require potable mixing water or

crosslinkers, the fluid is both practical and economical for use in a varietyof produced waters. Eliminating the need to purchase and transport potable water for fracture stimulation reduces cost, reduces demand onpotable water supplies, and contributes to the sustainability of favorablehealth, safety, and environment (HSE) conditions.

OmegaFrac® fluid is mixed from a dry polymer, reducing its potentialenvironmental impact (no hydrocarbons needed). The new Halliburtonadvanced dry-polymer (ADP™) blender was designed to blend any ofHalliburton’s fracturing fluids from dry polymer. The ADP blender is oneoutcome of Halliburton’s commitment to eliminate BETX (benzene,ethylbenzene, toluene and xylene) from fracturing chemistry. OmegaFracfluid can be mixed into tanks, or on-the-fly, with the blender. In typicalwater temperatures, 80% hydration can be achieved in under five minutes.Since there is no crosslinker, there are no additional liquid additive pumpsnor crosslink quality-control tests needed.

OmegaFrac fluid outperforms traditional crosslinked gels and offers an economical and superior alternative to surfactant-gel technology forfracturing low-permeability, medium temperature (150 to 250°F)formations with permeability below 10 md. In the resulting fracture, theretained conductivity of the proppant pack is often greater than 80%, andthe system breaks and cleans up effectively.

The low pipe friction generated by OmegFrac fluid makes it ideal forpumping down tubing and coiled tubing in multistage, pinpoint stimulationand for applications in unconventional reservoirs where high pressures arerequired at the fracture face.

Historically, the capability of a fracturing fluid to transport proppant hasbeen implied, based on fluid viscosity. The method does not completelyrepresent a fluid’s capability to place proppant since the elasticity of thefluid is not considered. The recently developed Mimic™ proppant transportdevice measures the capability of a fluid to transport proppant. The devicecan measure virtually any gelled fracturing fluid containing a wide range ofproppant particles. The Mimic device is an important supplement toOmegaFrac service.

OmegaFrac service fluid has the capability to perform without crosslinking and without liquid concentrates that require BETX tofunction. Further, it does not require transporting and consuming ever more scarce potable water. These attributes set OmegaFracservice widely apart from all other frac systems. Its sustainable HSE benefit alone is an important differentiator that showstechnological leadership.

OmegaFrac fracturing service is “fit for purpose” for unconventional tight-gas reservoirs. More information is presented in Chapter IV.

The ability to generate

OmegaFrac fluid on the-fly from

a dry polymer using a wide variety of produced water can represent a

significant benefit to Operators by

eliminating the needto acquire and trans-

port potable water.

Wells fractured with OmegaFrac service are already achieving

World Oil Awards

2008 Award: Best Data Application/VisualizationSolution: GeoSignalSM Measurement Service

Placing the well in the most productive part of the reservoir and keeping it there while drilling long horizontals is of primaryimportance for maximizing production. The GeoSignalSM measurement service provides a new visual entity synthesized frommultiple LWD measurements into an easy-to-read vector and map. Invented and developed in conjunction with the LWDAzimuthal Deep Resistivity sensor, the GeoSignal measurement helps visualize the position of the well with respect to geologicalsurfaces, in real time. The GeoSignal measurement service points to the nearest boundary of the reservoir and its magnitude is astrong function of the distance-to-boundary. With the aid of the GeoSignal measurement service, geosteering engineers are ableto visualize in real time the position of the well with respect to nearby top of tight-sand roof, water-gas contact or side edge of achannel sand. By combining multiple readings from coil arrays operating at multiple frequencies, the GeoSignal measurementservice readily indicates the direction to, and the distance from a conductive shale, a water zone or some other nonprospectivelayer or formation. The direction and magnitude of the GeoSignal measurement service, together with the GeoSignal maps,allows geosteering engineers to anticipate the reservoir boundaries, the gas-water contact and the side boundaries, well beforethey intersect the well path.

The method for computing the GeoSignal measurement service is patented. The concept of the GeoSignal measurement servicehas the same technological impact on electromagnetic logging of high-angle and horizontal wells as the radial geometrical factor has had on induction logging in vertical wells. While the radial geometrical factor predicts the signal from cylindricallayers surrounding the wellbore, the GeoSignal measurement service describes the response of azimuthal deep-resistivity sensors to layered beds above and below the horizontal wellbore. This helps conceptualize and optimize azimuthal-resistivityarrays and their response.

From an economic standpoint, the GeoSignal service has a direct impact on the success of geosteering horizontal wells andachieving maximum reservoir contact, especially in complex geology. Under normal reservoir conditions, the GeoSignal servicecan sense an approaching boundary from as far away as 18 ft from the wellbore path. Determination of the two resistivitycomponents that are normal and parallel to the layering enables determination of electrical anisotropy in laminated reservoirsand quantification of the associated hydrocarbon content.

The full benefits of the GeoSignal measurement service can be realized in conjunction with the InSite ADR™ Azimuthal DeepResistivity sensor, when run as part ofSperry Drilling services’ StrataSteer® 3Dgeosteering service. In recentlyconducted commercial jobs, theGeoSignal service has provided thegeosteering engineer real-timeindication of the direction of, andestimated distance to the top andbottom boundaries of a producing zone,allowing the well to stay in-zone muchlonger than it would have otherwise.During drilling, real-time steeringdecisions have far-reaching impact onthe immediate production rate and thelong-term recovery rate from a well.

The GeoSignal measurement service is a patented visual entity deployed with the LWD Azimuthal DeepResistivity that helps visualize the position of the well with respect to geological surfaces, in real time. Itpoints to the nearest boundary of the reservoir and the measurement magnitude is a strong function ofthe distance-to-boundary.

World Oil Awards

2007 Award: The Innovative ThinkerInnovation: Dr. Phillip D. Nguyen, Halliburton

This award recognizes an individual or group of individuals who have demonstrated thought leadership in theupstream petroleum sector.

Dr. Nguyen is an established research scientist and developer of products and techniques that enhancepetroleum production, and is an industry authority on production enhancement. Evidence of Dr. Nguyen’sprolific mind and high energy-level are the 120 issued US patents, more than 50 pending US patents, numerous foreign patents, 44 scientific papers presented and 18 published technical articles thus far in a brief, 18-year career. Nguyen anticipates what will be needed before it is needed, although he stays in direct

contact with Halliburton field personnel and with operating-company customers to listen for problems and opportunities. His reputation in the petroleum industry extends to all corners of the world; he has traveled to five continents to listen to customer needs and presentresolutions to issues.

Nguyen was the Halliburton Inventor of the Year in 2005 for his work on Halliburton’s SandWedge® service, a novel method of preventingthe migration of fine particles in propped fractures; these fines damage gas production. The SandWedge service has been used in tight-gas assets for many years.

Dr. Nguyen’s approach to problem solving is to:• Examine the source of problems, not just solve the symptoms• Develop a fundamental understanding of the physics or mechanics of the problem• Approach the problem from different angles—innovative problem-solving; new-asset development; HSE aspects of

innovations; human interaction; field delivery; reliability; integration and consolidation of well-production steps for saving time, saving costs, and increasing production

• Be a team player.

The examples presented below discuss products and services applicable to (1) new completions at any depth, both land-based and offshore and (2) remediation of mature assets that have experienced reduced production levels.

• Developed new surface-modification agents (SMA) for use in controlling migration of formation fine particulates in propped fracturesor acid-treated formations to maintain well production. Current acid-stimulation treatments often provide only short-term productionincreases that may be followed by rapid decreases of production caused by migration and plugging of formation fine particulates inetched channels or wormholes. Treatment with surface-modifying agents applied following acid-fracturing or matrix-acidizingtreatment helps stabilize formation sands and fines and trap them in place after fracture acidizing so that the flow paths can remainopen without plugging. This innovation has contributed to production increases in tight-gas reservoirs, coalbed methane fields andgas shales. The average increase in cumulative production from the use of SMA has been 100%. In typical operations, the number ofwell workovers needed to replace electric submersible pumps and clean out production hardware and tubulars, is reduced to zero.

• Developed a chemical treatment process to combine water-control and sand-control treatments into a single treatment—solving one of the most costly problems challenging the gas industry today: water and sand production.

• Developed environment-friendly resin systems for stabilizing the formations surrounding the wellbore in long intervals. These systems provide safer and more economical resin systems than the older solvent-based resin systems. These resins also have fewercompatibility issues, especially during treatments for screenless completions in long or multiple intervals.

2005 Award: Best Data Visualization SolutionSolution: StrataSteer® 3D Geosteering Service

The StrataSteer® 3D geosteering service is the heart of a comprehensive suite ofwellbore-positioning technology that delivers maximum production. TheStrataSteer 3D service is crucial in placing a well correctly, especially in smallertargets that often require complex well paths and more precise wellbore positioning.Halliburton’s StrataSteer 3D service uses every aspect of today’s technologies: deep-reading LWD sensors, powerful visualization software and remote-operationscenters to deliver the most accurately placed wellbore, particularly inunconventional tight-gas reservoirs.

The StrataSteer 3D service has been applied in hundreds of wells, for more than 20international clients, with consistent results.

Horizontal wells have traditionally been drilled to increase production because theyincrease reservoir exposure to the borehole. Using the StrataSteer 3D service togeosteer, clients have increased the percentage of the drilled footage that is in directcontact with the reservoir. While most production figures are confidential, andimpact varies from client to client, increased production rates ranging from 10% toover 100% have been achieved. In addition, there has been a significant reduction inbypassed hydrocarbons, resulting in improved total-asset recovery.

Accurate wellbore placement reduces the need for geological sidetracks. This,coupled with a faster decision-making process, has led to a significant reduction in NPT. One client with hundreds of wells already drilledon its prospect realized a 30% reduction in NPT in the 100+ wells drilled using the StrataSteer 3D service.

Small geological faults cannot always be anticipated by seismic data, which often leads to borehole exits from the target zone and the drilling of nonproductive footage. These nonproductive intervals require changes in the completion design to ensure proper isolation. The StrataSteer 3D service facilitates rapid and accurate geological correlation so the precise location of these nonproductive intervals can be determined, and the completion design corrected prior to installation.

The StrataSteer® 3D system seamlessly integrates a wide variety of data sources into a flexible visual environment that enables the rapidinterpretation needed to make critical real-time decisions regarding trajectory changes. Specifically, it integrates a 3D earth model,directional well planning, a petrophysical engine and dynamic log correlation into a comprehensive well-delivery system.

The geosteering for entire projects is accomplished from RTOCs (Real Time Operations Centers) that are located either in the client’s orHalliburton’s offices. This allows project teams to control and optimize the drilling operation on multiple assets from a single location.

An operator drilling in the Middle East needed to optimize the productivity of a difficult reservoir without increasing the total cost of the operation.

Before drilling began on the interval, Sperry Drilling services studied offset data and developed several geologic models using theStrataSteer 3D service. Challenged with a narrow true-vertical-depth (TVD) window, during the drilling process Sperry used real-timeStellar™ logging-while-drilling (LWD) sensors, including the ALD™ azimuthal lithodensity sensor, for correlation, calibration and fine-tuning of predrilling models.

Around-the-clock monitoring of the real-time LWD data in the earth model allowed Sperry’s StrataSteer service specialist to quickly identifya deviation from offset data and to recommend an adjustment to the well trajectory. This correction allowed the operator to land the well 19ft deeper than planned, maximizing reservoir drainage. As a result, the StrataSteer service and real-time geosteering capability eliminatedthe need for a costly sidetrack. The StrataSteer service and the 6-3/4-in. ALD sensor enabled the operator to successfully hit all four targets.

Tight gas reservoir operators frequently call upon StrataSteer 3Dservice to get to the best sweet spots.

The intellectual patent section lists the Halliburton technologies that have been, or have the potential for direct or

indirect application as a tight-gas reservoir solution. In 2008, based on the number and technical quality of

U.S.-government-issued patents, as reviewed by an independent third party (the Patent Board), Halliburton was the

top innovator in the energy and environmental business sector and its patents had the highest impact on technology

developed by industry that year. In the first half of 2009, Halliburton continued as the top innovator among the oilfield

service providers.

Halliburton has led the energy and environmental industry in most of the Patent Board’s recent studies, which rank

companies on the basis of their science and technology strength, number of patents issued and stock performance

versus the industry sector. In 2008, Halliburton spent approximately $326 million on technology research and development.

While it may appear that some patents bring more value-added benefits to particular tight-gas assets than to others,

until we can discuss the details of these assets with you, the customer, the full value of any patent to the development of

these assets cannot be fully understood or appreciated. Once the issues and challenges are identified through mutual

collaboration, we can transfer the ideas and technologies contained in these patents into customized solutions to optimize

development of your assets.

The Patent Scorecard ranks corporate innovation using a series of metrics to determine - patent quality, technological strength and breadth of impact. Data through November 1, 2008.
