Big Muddy Field Low-Tension Flood-Demonstration Project. Fifth Annual Report, April 1982-March 1983

摘要

The Big Muddy low-tension flood is a commercial-size demonstration project consisting of nine 10-acre injection patterns in the heart of the Big Muddy Oil Field located 15 miles east of Casper, Wyoming. The main goal of the project is to provide data for commercialization of the process for the Big Muddy Field and similar Wyoming and Colorado fields. This report discusses the project performance during the last part of slug injection with particular emphasis on the analysis of the early oil response and the injectivity. Other work discussed in this report includes the pilot testing for an oil-treating facility which led to a new design. The oil production rate increased from about 75 BPD at year-end 1981 to about 170 BPD, or from about 4 percent to about 11 percent of the injection rate, in March of 1983. During the same period, the produced oil cut increased from 2 percent to about 5 percent. The low-tension slug injection was completed in August 1982 and injection of a polymer solution having the same mobility is continuing. The total low-tension slug volume was 873,000 barrels or 10.2 percent pore volume. 4 references, 91 figures, 19 tables. (ERA citation 08:055450)
