Coalinga: a polymer demonstration project. First annual report, July 1975--July 1976. [California]

Technical Report ·
OSTI ID:7228421
This project is a jointly funded venture between Shell Oil Co. and US ERDA that will test an enhanced waterflooding technique (polymer flooding) in the East Coalinga field of California. Objective is to determine if the added expense of a polymer flood over a conventional waterflood is justified in the Temblor Zone II reservoir. The 132-acre project area consists of four 22-acre inverted five-spot injection patterns plus a 44-acre up-dip area that will be monitored. The Temblor Zone II reservoir to be flooded consists of approx. 125 ft of net pay divided among ten sands within a 350-ft gross interval. Observation wells will be provided in addition to the production and injection wells. The project is organized into 5 phases: evaluation, development, water injection, polymer injection, and production monitoring. The water injection phase was initiated June 28, 1976, with injection of 5,400 barrels/day water into four injection wells, and it will continue for approx. one year. (DLC)
