The Upper Pennsylvanian Swope Limestone is a prolific oil and gas-producing reservoir in central and western Kansas and northwestern Oklahoma. However, rapid lateral variations in the oolitic lithofacies impede the prediction of reservoir quality from available well control. A detailed attribute modeling and interpretive analysis using MIRA (Oklahoma Seismic Corp.) software of Vibroseis-acquired and conventional zero-phase processed seismic were conducted on the Swope interval in Comanche County, Kansas, and Woods County, Oklahoma. Three discrete ranges of fluid-filled porosity thickness can be delineated: less than 1.5 m, 1.5-3.0 m, and greater than 3.0 m. Thin-bed detection below the classic 1/30 wavelength threshold is possible in this setting owing to constructive wavelet tuning from multiple acoustic interfaces. Optimal application of this attribute modeling/interpretation method to oil and gas exploration and exploitation is controlled by the accuracy of the geologic model and the quality of the acquired and processed data.
