Industry Article: 3D PP/PS prestack depth migration on the Volve field

Ocean-bottom seismic (OBS) methods record both compressional (PP) and converted shear-wave (PS) data. PS data have successfully been used to image through gas-obscured zones (Li et al., 2001) and to image reflectors that are weak on PP data (MacLeod et al., 1999), and can also help constrain rock property estimates (Özdemir et al., 2001). Thus, in principle, the use of PS data can significantly mitigate risk in hydrocarbon exploration and production.
