Increasing waterflood reserves in the Wilmington oil field through improved reservoir characterization and reservoir management. Quarterly report, October 1 - December 31, 1996

The main objective of this project is the transfer of technologies, methodologies, and findings developed and applied in this project to other operators of Slope and Basin Clastic Reservoirs. This project will study methods to identify sands with high remaining oil saturation and to recomplete existing wells using advanced completion technology. The identification of the sands with high remaining oil saturation will be accomplished by developing a deterministic three dimensional (3-D) geologic model and by using a state of the art reservoir management computer software. The wells identified by the geologic and reservoir engineering work as having the best potential will be logged with a pulsed acoustic cased-hole logging tool. The application of the logging tools will be optimized in the lab by developing a rock-log model. This rock- log model will allow us to convert shear wave velocity measured through casing into effective porosity and hydrocarbon saturation. The wells that are shown to have the best oil production potential will be recompleted. The recompletions will be optimized by evaluating short radius and ultra- short radius lateral recompletions as well as other techniques. Accomplishments for the past quarter are summarized for: reservoir characterization; reservoir engineering; deterministic 3-D geologic modeling; pulsedmore » acoustic logging; recompletions; and technology transfer.« less
