ABSTRACT:
An improved method is disclosed for obtaining shear wave data from common depth point gathered compressional wave traces using variations in the amplitude of the gathered compressional waves with source receiver offset. The gathered compressional waves are corrected for normal moveout and the normal moveout corrected waves are further corrected for residual normal moveout by correcting stacking velocities of the normal moveout corrected traces.
