Oil supply forecasting : a disaggregated process approach

Abstract

Work is under way on a forecasting method that incorporates explicit representations of the steps in the oil supply process: exploration, reservoir development, and production. The discovery history of a region and other geological data are inputs to a statistical analysis of the exploratory process. The resulting estimate of the size distribution of new reservoirs is combined with an evaluation of reservoir economies -- taking account of engineering cost, oil price, and taxes. The model produces a forecast of additions to the productive reserve base and oil supply. Progress to date is demonstrated in an application to the North Sea.
