The early phase of any project is where the most value can be added. During the Select phase, TARGET’s surface team works closely with the subsurface team to ensure the optimal development concept is delivered. Key elements of the select phase are Field Development Planning and Conceptual Definition.


Field Development Planning

Field development planning studies provide the necessary information and advice for:

  • establishing whether or not a project is economic
  • shortlisting development project options by screening
  • selecting an optimal development concept for a project


TARGET provides decision support at each of these stages using a proven approach and a structured framework to ensure the correct decisions are made. This eliminates bad decisions, which could otherwise come from poor framing, from not adhering to a clear and structured process and from not evaluating all of the options on an equitable basis.

These early phases of a project are where most value is created or lost. Poor decisions here cannot be recovered in the project execution. The TARGET process, used on all early phase studies, ensures that:

  1. all the potential contributors to the value of the project are considered and, where possible, quantified – not only CAPEX but also OPEX, schedule, availability, recovery, flexibility, safety, environmental and project risk and uncertainty – to ensure an equitable basis for concept selection;
  2. there is an audit trail for the decision process, with a robust basis and clear reasons for the elimination of alternatives;
  3. the choices and concepts that provide the maximum project value are identified and the results are assured;
  4. threats to the success of the development and potential sources of reduction in the economic value of the project are identified and assessed.


Conceptual Definition

Concept Definition, or Pre-FEED, adds a further level of detail to the shortlisted options identified in the field development planning phase to achieve more precise definition, a better cost estimate, and ultimately, selection of a single option for FEED.

Activities in Concept Definition are chosen to address the development’s circumstances and can include:

  • Process scheme optimisation
  • Reduction in optionality using targeted studies of particular aspects of design
  • Finalisation of field architecture
  • P&ID initial development
  • Layout development
  • Issue of enquiries for long lead or high cost items
  • Cost estimating and economic assessment
  • Project schedule enhancement
  • Preparation of survey scopes of work, tendering and management of the work
  • Engagement with other work groups and third parties to reduce uncertainties e.g. drilling, reservoir engineering, tie-ins to other facilities, regulatory authorities, buyers of products
  • Development of risk mitigation plans
  • Project Execution Plan and contracting strategy finalisation
  • Basis of design update
  • Commencement of the ESIA process


As a result, the development enters FEED with a single, well defined option: the development’s major design issues have been decided, risks and uncertainties are understood, and the cost estimate, budgets and schedules are clear and complete.
