ABSTRACT
A comprehensive well management program developed for use with current state-of-the-art black oil simulators during the prediction phase of reservoir performance studies, is presented. The reservoir is modelled as a hierarchical system possessing field, group, and well levels of control at which production and injection specifications and constraints can be imposed. The program enables wellhead rate changes, shut-in and reopening of wells, workovers, stimulations, artificial lift, and the drilling of new wells to be executed automatically to maintain production and injection levels. It also has the capability to automatically maintain the average reservoir pressure within specified limits through injection and production rate changes. This program incorporates a high degree of functional logic and many new concepts, strategies, and options not reported previously in the literature.
In this paper, the logical structure of the program, its optional features, and the strategies employed at different levels of control to meet the reservoir management objectives are described and are illustrated through specific numerical examples.
