An Integrated Study of the Grayburg/San Andres Reservoir Foster and South Cowden fields,
GEOPHYSICAL OBJECTIVES: The goals of work done this quarter were to (1) refine the maps of seismic-derived porosity for the upper Grayburg for reapplication to the production model, (2) determine rock fabric and porosity patterns for the lower Grayburg and the upper San Andres, (3) relate any seismic-derived porosity characteristics, particularly seismic waveform attributes, to the historical production of oil allocated to lower Grayburg and San Andres zones, and (4) to test other geologic attributes for possible inter-relationships. GEOLOGIC OBJECTIVES: Continue the integrated geological/geophysical effort to develop a usable seismic velocity/log porosity transform for each Grayburg producing interval. The lower Grayburg and San Andres core were revisited to glean lithology and porosity information for the seismic inversion model. Update recent production and injection for each well in the study area. Add new production and injection wells to spreadsheet. Continue evaluation of effectiveness of recent completions, plug backs and injector conversions by monitoring oil production and produced water composition. ENGINEERING OBJECTIVES: To build the most accurate reservoir picture by continued integration of all data types available and utilize that model to optimize oil production. Monitoring and testing of new and worked-over wells continues to test the early production models. Methods to improve water quality are being evaluated using normal field management procedures.
