f Extraction of accurate P- and S-wave velocities from fixed offset well seismic profiles, UK Central North Sea

The acquisition and processing of both compressional and shear wave energy from Well Seismic Profiles (WSP) is an important source of data for the investigations of seismic Amplitude Versus Offset (AVO) and anisotropy. In the marine environment we are normally dependant upon the mode conversion of conventional compressional sources (air- or watergun) for the production of shear wave energy.
