An integrated study of the Grayburg/San Andres reservoir, Foster and South Cowden Fields, Ector County, Texas
An enhanced oil recovery project is being proposed in response to the US Department of Energy`s Near Term Class 2 Oil Program for shallow shelf carbonate reservoirs. Productivity problems associated with a shallow shelf carbonate reservoir will be addressed by integrating high resolution 3-D seismic data, reservoir characterization techniques, and 3-D reservoir simulation. The purpose of the study is to yield results which will preserve access to existing well bores by identifying additional reserves. The general approach will be to shoot a 3-D seismic survey designed specifically for imaging the Grayburg/San Andres interval. The data will then be processed and interpreted using state of the art techniques aimed at identifying porosity, permeability barriers and their zones within the reservoir. A technical team will integrate existing geological data with the geophysical results of the seismic survey for detailed reservoir characterization. These results will be used in a 3-D reservoir simulation model to delineate flow units. A field demonstration of infill drilling and water flood development will follow. The authors expect the results of this study to demonstrate a methodology for reservoir characterization 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. Additionally, it will showcase the improvement of water flood development by using an integrated multi-disciplinary approach, and the addition of otherwise unrecovered reserves by selective infill drilling. This report has four sections: summary of preliminary data; plots and maps; well production data; and well data.
