Mapping Structural Deformation Associated with the Formation of the Blue Ridge Salt Dome

Abstract

Geologic mapping and subsurface imaging around salt has remained difficult. Seismic imaging is difficult near salt due to the large velocity contrasts between salt and the surrounding rocks, the steeply dipping salt and sediment interface, and the presence of pinching beds on the flanks of the dome; but when combined with well control from previously drilled wells on top and on the flanks of a salt dome, a more complete profile of the subsurface structure becomes possible. Previous work has produced models of salt dome formation and the surrounding structural deformation, and when compared to seismic data, show a good correlation. In this study, well log and seismic data from the Blue Ridge Salt Dome in Fort Bend County, Texas will be used to generate a structural profile. The comparison from this structure profile produced from field data to previously modeled dome centered deformation will also be made. By creating this structural profile in conjunction with previous works, this study will test previous models of salt dome evolution as compared to the Blue Ridge Salt Dome.
