The Coalinga Polymer Demonstration Project in California is designed to test polymer flooding as an enhanced waterflooding technique and to provide a direct comparison between waterflooding and polymer flooding. The demonstration project has been organized into five phases: evaluation phase, development phase, water injection phase, polymer injection phase, and production monitoring phase. Field testing and the selection of the pilot site were completed during the Evaluation Phase. The drilling of new wells, the reconditioning of wells, and the installation of injection and production facilities were completed during the Development Phase. The Water Injection Phase began in June, 1976, with the injection of 5400 barrels per day into four 18-acre inverted five-spot injection patterns. The total 116-acre project area also includes a 44 acre updip area (with no injection wells) that will be monitored. The Polymer Injection Phase began in May, 1978, and is expected to continue for two to three years. The Production Monitoring Phase will consist of one year of data gathering and reporting. Additional water injection will follow the polymer slug for eight years.
