The injection of the polymer-pusher slug continued through the third quarter of 1984. A short-term plant shutdown occurred in September due to a power failure; however, no problems resulted as operations continued smoothly. A total of 1,233,700 barrels of polymer-pusher slug has been injected through September 30, 1984, which is approximately 70% of the planned slug size. The average injection for September was 1142 BPD. Injection rates were cut another 15% on September 12 as further tests were conducted to define parting pressures. Oil production declined from 173 BOPD in June to 151 BOPD in September. Cumulative project production is 197,649 barrels of oil as of September 30, 1984. Sulfonate production was observed in all wells with Wells 91 and 88 showing the highest levels (1875 to 1250 ppM, respectively). The production-weighted average has dropped from 400 ppM in June to 280 ppM in September. The auxiliary treating facility for sulfonated oil was fully operational and continued to achieve merchantable oil.
