Single-well evaluation program for micellar/polymer recovery, Main and 99 West Pools, West Coyote field, California
The Main and 99 West pools of the West Coyote field were selected as promising candidates for a micellar-polymer recovery project. Waterfloods initiated in 1961 are nearing their economic limit, with a current watered-oil ratio of 45. Well No. MC 374 was drilled in a water-out portion of the Main and 99 West reservoirs to accomplish an evaluation program with the following objectives: (1) provide data for an improved geologic model; (2) estimate current oil in place; and (3) determine the effectiveness of micellar-polymer chemicals in displacing residual oil. Well No. MC 374 was extensively cored and logged to provide the necessary geologic and reservoir data. A multi-well interference test was conducted to confirm reservoir continuity near the test well. Displacement tests were run in 2 intervals with micellar-polymer chemicals. 13 references.
