Sinkhole and vertical collapse features associated with paleokarst have been observed in Hughes and Coal counties of Oklahoma using 3D seismic data and attributes that enhance these features. Vertical pipe structures are interpreted as mature paleokarst collapse features originating below the Viola limestone extending upwards beyond the Mississippian Caney Shale and terminating in the Pennsylvanian Cromwell sandstone. These collapse features are coincident with sinkholes that have been characterized in the Viola. These pipes features are evident on time structure maps and are 700–1600 ft deep relative to uncollapsed formation tops, have diameters of 500–1700 ft and are 1500–7000 ft apart. We also observe circular features in the Pennsylvanian Wapanucka limestone on seismic amplitude which suggests the presence of immature paleokarst sinkholes that are not mappable on time structure. These Wapanucka circular features are mostly coincident with the vertical collapse features observed in the Viola limestone several thousand feet below.
