Abstract

3D seismic data acquisition brought a sea change in subsurface imaging. The bridge between geology and seismic is P/S wave velocity of different subsurfaces/lithology. The technique has acquired prime importance due to its inherent strength of determining seismic velocity/amplitudes of the different medium. Lithological variations estimations is possible due to proper Vp/Vs ratio or either velocity alone. Success of advance seismic studies solely depends on accurate subsurface mapping
