Abstract

Salt dissolution occurs when evaporite-dominated rocks come into contact with NaCl-undersaturated fluids. Salt dissolution can positivity and negatively impact hydrocarbon and mineral exploration, seismic imaging, drilling, and structural restorations in salt-bearing sedimentary basins. However, due to typically poor seismic imaging and a lack of borehole data, few studies have analysed the detailed morphology of salt dissolution-related features (i.e., salt karst) and how this relates to intrasalt stratigraphic heterogeneity, and associated deformation within post-salt overburden. Here we integrate high-quality 3D seismic reflection data, a ...  more
