The purpose of the reservoir evaluation is to determine the reservoir production potential and develop the conceptual field development plan. This information allows field development costs to be assessed and determines the attractiveness of the economics and the ability to underwrite the development.
The reservoir evaluation for marginal fields provides a formal risked reserves statement which is then translated into life-of-field production profiles to reflect income potential. The conceptual field development plan is then set and phased against projected income to show cash flow, margins, and investment merit.
