Field Development Planning

Objective and Plan

Objective

To devise a Field Development Plan for the Lismore Field in the Central North Sea. Comprising: - Analysis and modelling of data from the exploration and appraisal programme - Resource estimation and lifecycle production forecast for the field - Selection of subsurface and surface engineering plans - Economic screening - Reporting and presentation to the board

FDP workflow – DECC guidelines

Definition

The objectives of the FDP

Data

Inventorise, review, request additional data (?)

Alternatives

Generate alternative subsurface and surface options

Analysis

Model the alternatives; investigate implications of each

Select

Select the best scheme based on economics and risk, set against the FDP objectives

Define the project

Detail the best option and take to point of sanction

FDP content – DECC guideline
