Field development plans (FDP’s) are focused documents describing the technical assumptions and analyses underlying the planned extraction, processing, transportation, and sale of the hydrocarbons in a specified geographical area and geological horizon(s). This incorporates multi-disciplinary inputs including subsurface, wells and production technology, surface facilities and operations. The field development plan in many jurisdictions informs the regulator of the intended plan to develop the resource. A field development plan is therefore prescriptive and is meant to detail the proposed reservoir development, and may include well locations, design and completion, project schedule, operations plan and abandonment. While a single plan is the result from the field development planning process the alternative concepts considered and the rationale for selecting the chosen concept can be included. Each development plan concept being considered will also include its economic implications. Field Development Plans are often used to support the asset development plan.
