The East Vacuum Grayburg/San Andres Unit (EVGSAU), operated by Phillips Petroleum Company, is the site selected for a comprehensive evaluation of the use of foam for improving the effectiveness of a CO{sub 2} flood. The project began in late 1989, and is now in the final year. A field test of CO{sub 2}-foam has been successfully conducted, and preliminary results are promising. Response in the foam injection well has been as anticipated, and an offset producing well has experienced a positive oil response as a result of the foam test. Based on the favorable results observed in the foam injection test, a second foam test was conducted. The monitoring program includes analysis of injectivity data, pressure falloff tests, observation well logs, interwell tracer response, production logs, history of production rates, and changes in gas-oil ratio. This annual report provides recent results from the project.
