Offshore Trinidad Tilted Orthorhombic Imaging of Full-Azimuth OBC Data

Summary Azimuthal anisotropy in sediments is seen in many areas around the world, usually associated with regional stress and fracturing. With full-azimuth data it is possible to detect and to resolve this anisotropy. In this case study we describe how significant azimuthal anisotropy was found on full-azimuth ocean-bottom cable (OBC) data from offshore Trinidad, and how orthorhombic velocity modelbuilding and depth imaging were applied to produce superior seismic images.
