Integrated Reservoir Management via Full Field Modeling, Pt. McIntyre Field, Alaska

Abstract

Abstract Development drilling, depletion planning, and waterflood management have been guided by the use of a finely gridded full field reservoir simulation model (FFM) since startup of the Pt. McIntyre field in October 1993. A detailed geologic model formed the basis for development of the reservoir simulation model. A multicompany, multidisciplinary team used 3D seismic interpretation and data from over 7000 feet of core to provide the foundation for this geologic model. The full field model constructed from this geologic framework yields an excellent match to field history, including individual well matches, with very little "history matching" required. The model has been used to address a wide range of reservoir management issues in addition to providing conventional long-term reservoir performance forecasts. Development and infill drilling assessments, facility expansion evaluations, and individual well work forecasts have been based on FFM results. More novel applications of the model include waterflood optimization and hydrocarbon miscible EOR evaluation. The FFM has been the focal point for integrating geologic, petrophysical, reservoir surveillance, and surface facilities information to improve reservoir management decision making at Pt. McIntyre.
