Dynamic parameters - equations

− Darcys law Q = -K A (Pb – Pa) / viscosity * L

− Production Index PI = QT/(PG – P)

• The productivity index (PI) takes into account the reservoir

characteristics at the inlet of the well, through the specification of a

relation between the inlet total flow rate QT, the well inlet pressure P and

the reservoir pressure PG. For a one phase oil well or for a two phase

gas-oil homogeneous mixture in the well, the relation is given by:

QT = PI(t) * (PG - P)

Needs for Exploration projects passing DG0

2014-08-04 11 Classification: Open

Exploration projects passing DG0 shall demonstrate economic potential

for the discovery and that the in-place volume uncertainty has been

reduced to a level that it is not the main development risk.

The DG0 shall be approved by the receiving business area, based on

a recommendation from the Exploration business area. Required work leading up to DG0:

When appraisal is needed or warranted:

Conduct appraisal activities and evaluate results

Evaluate and QC volumes and remaining risks of the discovery. The volume estimates

shall be based on the expected discovered recoverable resources with associated

ranges (P90-P10) included, and the economics shall be calculated for this case

Identify and assess additional prospects and segments that may impact the

development concept.

For unconventional hydrocarbons this will mean additional subsurface potential in general

update the value of the business case

BUSINESS PLANNING (DG1)

2014-08-04 12 Classification: Open

The purpose of the business planning phase (leading up to DG1)

is to justify further development of the business case, and the

establishment of an investment project.

Feasibility studies shall demonstrate that one concept is

technically, commercially and organizationally feasible, and that

value chain fit, economic analysis and relevant stakeholder

analysis justify further development. The business planning phase shall:

Frame the business case, develop objectives and set direction

Document that the business case is in line with group strategies

Identify possible development stoppers

Demonstrate technical- and economic feasibility

Identify possible concepts and any added value opportunities

Identify the needs and potential for new technology

Identify schedule for regulatory applications

Align relevant stakeholders around further development

Establish the decision documents for DG1

CONCEPT PLANNING (DG2)

2014-08-04 13 Classification: Open

The purpose of the concept planning phase (leading up to

DG2) is to identify alternative concepts, select a viable

concept, define and document the selected concept and

develop Design basis for approval at DG2. A concept is described with the following main elements:

Commercial (e.g. legislation, agreements, licensing, financing, marketing and supply, product

sharing, taxes)

Reservoir or energy resource (e.g. depletion strategy, flow assurance)

Technical (e.g. drilling & well, facilities)

Operations (e.g. plant start-up, operation and maintenance)

The concept shall be selected based on defined criteria in due time prior to DG2.

The concept planning phase shall:

Provide a firm definition of the Design basis

Evaluate and compare alternative concepts

Screen-out non-viable options and mature the preferred concept to fulfill business case objectives

Develop basis for project execution (including identification of applicable permits or regulatory

approvals)

Align relevant stakeholders around further development

Establish the decision documents for DG2

DEFINITION (DG3)

2014-08-04 14 Classification: Open

The purpose of the definition phase (leading up to DG3) is to

further mature, define and document the business case based on

the selected concept for project sanction.

Any options or technical solutions not selected prior to DG2 shall

be decided prior to DG3. The definition phase shall:

Execute Front End Engineering Design (FEED) studies

Mature the business case to avoid late project changes

Plan and prepare the execution phase

Prepare submittal of application(s) to the authorities

Establish the basis for agreement (e.g. contract) awards

EXECUTION (DG4)

2014-08-04 15 Classification: Open

The purpose of the execution phase (leading

up to DG4) is to realize the business case. The execution phase shall:

Detail design, procure, construct (including install) and complete the agreed facilities and

wells

Perform handover to Asset / operations

Prepare for start-up, operation and maintenance

Establish Termination agreement
