Recording and processing both the converted shear waves and the compressional waves from multicomponent ocean bottom seismic (OBS) data provide additional opportunities to understand the subsurface. The converted waves are generally used to provide complementary images and velocity information to support the conventional seismic model. However, they also provide a new opportunity to measure and understand shear-wave azimuthal anisotropy. This paper describes the results from an azimuthal anisotropy study on 3D 4C OBS data from Valhall Field.
