Title: Single-well evaluation program for micellar/polymer recovery, Main and 99 West Pools, West Coyote Field, California

Abstract

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 water-oil ratio of 45. Well MC 374 was drilled in a watered-out portion of the Main and 99 West reservoirs to accomplish an evaluation program with the following objectives: provide data for an improved geological model; estimate current oil in place; and determine the effectiveness of micellarpolymer chemicals in displacing residual oil. MC 374 was extensively cored and logged to provide the necessary geological and reservoir data. A multi-well interference test was conducted to confirm reservoir continuity near the test well. Displacement tests were run in two intervals with micellar-polymer chemicals. Oil saturations in the near-wellbore area were measured before and after the displacement tests using log-inject-log and single-well-tracer techniques. An extended polymer injectivity test was conducted in one of the intervals.
