Raypaths for P-SV-converted waves are asymmetrical and the reflected events are not hyperbolic. Consequently, standard routines for NMO correction of P-waves cannot be applied in a straightforward manner. This is a major difficulty in data processing of P-SV-converted waves.This paper proposes a new strategy for common conversion point (CCP) stacking. The technique accomplishes reflection point migration, nonhyperbolic moveout, and CCP stacking in one step.
