DIP‐MOVEOUT AND REFLECTOR POINT DISPERSAL*

Abstract

A bstract Application of dip‐moveout attempts to correct pre‐stack data in such a way that they stack correctly, however far the reflector geometry departs from an ideal plane horizontal interface. Even for plane dipping reflectors under a constant velocity overburden a common mid‐point gather contains reflections distributed over a finite segment of the reflector. It is shown that under these conditions application of dip‐moveout moves dipping energy on common offset gathers in such a manner that common mid‐point gathers become true common depth point gathers.
