Shot Based Pre-Processing Solutions for a WATS Survey – An Example from a Field Trial in Green Canyon – Gulf of Mexico

摘要

In July 2006, a 3D Wide Azimuth Towed Streamer (WATS) field trial was carried out in a deep water area of Green Canyon in the Gulf of Mexico. The purpose was to provide insight into the potential problems and complexities of such seismic datasets and to challenge conventional and newly developed true 3D preprocessing sequence algorithms. The results indicate that a 3D shot based processing sequence is an effective and flexible processing solution that realizes the maximum benefit of a full 3D wave field recorded as a Wide Azimuth acquisition and properly takes into account all the effects related to the complexity of the acquisition.
