Abstract
The complex northern Campos Basin overburden, including seafloor canyons, buried channel complexes, fault shadows, carbonate rafts and salt, introduces structural artifacts and contribute to the poor quality of the in a prestack time-migrated (PSTM) image. Several approaches to time-to-depth stretching could not effectively resolve the overburden complexities, thus an anisotropic pre-stack prestack depth migration (PSDM) was applied to the data, leading into a high quality product that supported an enhanced interpretation of the underlying geology.
