“…The Stone Corral anhydrite is stratigraphically just above the Hutchinson Salt in areas where the salt is greater than 250 m deep, laterally continuous with widespread regional distribution. It is an excellent acoustical marker because it is a significantly high velocity material, incased within lower velocity shale (McGuire and Miller, 1989).…”

Time-lapse 2-D high-resolution seismic reflection surveys successfully imaged and mapped changes in structural features associated with a sinkhole that formed catastrophically after dissolution of the Permian-age Hutchinson Salt in central Kansas (Figure 1). Symmetric steep sided cone structure defined by reverse faults formed instantaneously continuing over time to gradually enlarge and elongate along normal fault planes. Two orthogonal high-resolution seismic lines were acquired, in 1998 and 2004, to map the upper thousand feet and resolve structural features controlling development subsidence rate preferential dissolution mechanism for fluid movement and to predict future growth. High frequency vibrator and high-resolution seismic methods were used to acquire data from a 204 channel fixed spread. Stations used in 1998 were as close as possible reoccupied on the 2004 survey. Common mid-point stacked sections depict a very disturbed subsurface that has undergone multiple discrete phases of loading, failure, and subsidence. Stress built up in roof rock overlying the salt void until its strength is surpassed when failure, and subsidence occurs (Figure 2 (a), (b), and (c)). Strain associated with layers bridging voids outside the tensional dome appears to be controlled by normal faults. Oilfield disposal practices provided original fluids and pathway that initiated the dissolution process. Currently shallower groundwater fuels the dissolution process with little or no contribution from oilfield brines. Growth appears to be controlled by geologic trends with failure occurring much more plastically during the later years, which initially growth was characterized by rapid brittle deformation.
