Pilot Demonstration of Enhanced Oil Recovery by Micellar-Polymer Waterflooding. Quarterly Report, Second Quarter, 1980: Phase D

摘要

Response to the micellar-polymer injection continued during the quarter with no significant changes in total pool performance. The pool oil rate increased and the water-oil ratio declined, but the rate of change of both parameters appeared to be levelling off. Well T-104, the first well to display production response to chemical flood, has reversed the favorable trend and shows a reduction in both oil rate and oil cut. Several wells were off production during the quarter with numerous problems, predominantly sand control problems. The polymer buffer, currently at a concentration of about 2200 ppM, has continued to be injected at a fairly constant rate of 2000 B/D with no major upsets. Approximatey 39 percent of a pore volume has been injected. (ERA citation 06:028160)
