Polymer injection continued through the first quarter of 1983, bringing the total polymer-pusher slug size to 361,000 barrels. The average injection rate for the quarter was 1648 BPD, and the rate for March averaged 1706 BPD. This higher rate, compared to the 1982 fourth quarter average of 1515 BPD, was due to increased injection into R.B. Whiteside No. 101. Injection into R.B. Whiteside No. 101 was increased by placing a Triplex pump at the well in mid-February. The rate jumped from 28 BPD in January to 173 BPD in March; however, the bottom-hole injection pressure also increased from 1323 psi to 1620 psi. Pressure-parting (step-rate) tests were unsuccessful in defining the fracturing pressure. Further analysis will include tracer surveys, fall-off tests and observation-well pressure measurements in order to monitor the effects of the increased injection. Oil production continued to increase during the quarter with sales averaging 175 BOPD, 167 BOPD and 172 BOPD for January, February and March, respectively. January was high due to 400 barrels of bad oil produced in December; actual production for January was 162 BOPD. Cumulative project production is 93,685 barrels of oil as of March 31, 1983. Minor sulfonate production (200 to 500 ppM) was observed in Wells Nos. 83, 87, 88 and 95; however, no serious treating problems have occurred yet. The sulfonated oil auxiliary treating facility is very close to completion and will be ready for startup by late May. 6 figures, 4 tables.
