3D GEOLOGICAL MODEL OF WEST WAHA AND WORSHAM BAYER FIELD, WEST TEXAS

Three-dimensional, (3D), seismic and well data were acquired from a 20 square mile area of the West Waha and Worsham Bayer Field, located in the vicinity of the Delaware Basin, West Texas. This field is being explored for secondary gas recovery. The 3 D seismic data was modeled with the information from the seismic data and logs from well number 29. Formations from this area have been structurally identified, based on the well log data that was converted to time depth to match the seismic map. All available wells have been plotted based on their coordinates and depth. A cross section map was created with identified formations and a base map was also formed showing the location of available wells from the data. The Ellenburger group has been identified as the major gas producing formation. Three other formations, (Simpson group, Thirtyone formation, and Undifferentiated Mississippian limestone) are also possible producers. Surface horizons were selected and ascribed to formation tops including two horizons from the topmost formation. A strata grid was constructed in three dimensions to show the true thickness of the identified formations. A time slice with transparency on the surface of the Ellenburger group was generated in black and white and multicolor resolution. All available well logs from well number 29 were correlated with the synthetic seismic trace. This geological model will allow better visualization and understanding of this area as well as the prospect for future hydrocarbon exploration.
