The injection of the polymer-pusher slug continued through the end of 1984. No power failures or plant shutdowns occurred in the fourth quarter. A total of 1,335,000 barrels of polymer-pusher slug has been injected trough December 31, 1984, which is approximately 75% of the planned slug size. The injection was 1136 BPD in December, down from 1700 BPD in 1983 due to intentional step-downs in rate. These cut-backs were made to elimate suspected pressure-parting, but they were insufficient even after a total 35% cut in rate. Oil production declined from 151 BOPD in September to 119 BOPD in December. The production for December was low due to 420 barrels of oil which did not ship thorugh the LACT (pump failure). Cumulative project production was 209,468 barrels of oil as of December 31, 1984 (sales only). Sulfonate was produced in all wells with Wells 88 and 91 showing the highest levels (1875 ppM and 2500 ppM, respectively). The production-weighted average was about 350 ppM, yet most wells were 200 ppM or less in sulfonate. The auxiliary treating facility for sulfonated oil was fully operational and continued to achieve merchantable oil. 6 figures, 4 tables.
