A field demonstration test of displacement mobility control in the East Coalinga Field is being conducted in order to determine the relative merits of polymer flooding and waterflooding in a medium viscosity oil reservoir. The injection pattern consists of four inverted 5-spot patterns and an updip area. Water injection began in June 1976 and continued through April 1978. Polymer injection began in May 1978 and is ongoing. The overall production performance for the pilot has been far less than expected. The current oil production rate is currently below the expected primary decline rate. The polymer injection rate is substantially below original predictions and will increase the time required to inject the designed slug volume.
