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. Other objectives are discussed in previous annual reports. This report discusses the project performance during the polymer drive phase with emphasis on the analyses of oil cut, pattern balance, and early tracer response. The oil rate increased only slightly during 1983 and began to flatten near year-end at about 210 barrels per day or 12% of the injection rate. The injection rate was increased in late 1982 and early 1983 but simply resulted in a net input (influx plus injection) greater than production with only slight improvement in oil rate. In fact, the imbalance is suspected of contributing to the early flattening in oil production. Though the project oil rate flattened, an increased cut was observed in the north row of wells, indicating an oil response to slug injection in all wells except Well 54. Also during 1983, the polymer drive volume increased to about 10% of pore volume or to the midpoint of the polymer drive. Tracer and slug components have still appeared in only a few wells, even after 20% pore volume injection. Oil treating was becoming more troublesome but was relieved when the new treating facility was put into use. 5 references, 91 figures, 7 tables.
