An integrated study of the Grayburg/San Andres Reservoir, Foster and South Cowden Fields, Ector County, Texas. Quarterly technical progress report No. 3, February 1, 1995--April 30, 1995

The objective of this study is to demonstrate a methodology for reservoir characterization of shallow shelf carbonate reservoirs which is feasible for the independent operator. Furthermore, it will provide one of the first public demonstrations of the enhancement of reservoir characterization using high resolution 3-D seismic data. This particular project will evaluate the Grayburg and San Andres reservoirs in the Foster and South Cowden Fields of Ector County, Texas. We intend to showcase a multi-disciplinary approach to waterflood design and implementation, along with the addition of reserves by selective infill drilling. We believe this approach in reservoir development will be applicable to a wide range of shallow shelf carbonate reservoirs throughout the United States. Technology transfer will take place through all phases of the project. Progress reports are presented for the following tasks: geological; reservoir engineering; and geophysics
