Abstract

3-D seismic data were collected in a mature oil producing area ½ mile east of Catherine, Kansas. The study area, located approximately ten miles south of Bemis-Shutts oil field, encompasses 960 acres and contains 31 producing wells. Since 1948, wells within the study area have produced approximately 2.5 million barrels of oil form the Landsing-Kansas City groups and the Arbukle. 3-D data were acquired using Vibrosels1 with sweep frequencies of 20-128 Hz. Geophone and source intervals of 165 feet resulted in bin sizes of 82.5 x 82.5 feet. Data were processed using a standard processing flow, including: spiking deconvolution, stacking, migration, and static corrections. Interpretation of the migrated 3-D volume identified high-angle normal basement faulting. Basement uplift resulted in differential erosion of the Arbuckle surface exposing different units at the sub-Pennsylvanian unconformity. Faults also acted as conduits for vertical fluid movement enhancing karstification, resulting in collapse and sagging of the Lansing-Kansas City groups. Karst collapse and sagging of Middle Pennsylvania units created distinct productive plateaus within the study area. In addition, #-D interpretation identified numerous small dolines that modified the plateaus but were into genetically related to basement kinematics. Interpretation also identified several possible development drillsites.
