The Common-Reflection-Surface (CRS) stack accounts for local dip and curvature of reflectors in depth. Thus its stacking parameters carry far more information about the subsurface than conventional stacking velocity. This information allow us to provide a superior basis for subsequent applications. NIP-wave tomography inversion is one of these applications which uses NIP-wave curvature, emergence, angle and coherence for velocity inversion. In this paper we applied the CRS method on a complex structure in North East of Iran and then we performed the NIP-wave tomography inversion on this data set. The result clearly shows the usefulness of CRS attributes and the ability of this method for velocity model inversion.
