Prestack Depth Previous HitMigrationNext Hit (PSDM) is a process in correcting data seismic by doing Previous HitmigrationNext Hit before stack in depth domain. PSDM is a powerful tool for complex geology structure that has horizontal and vertical Previous HitvelocityNext Hit variation. PSDM with finite difference method has been done by iterative process of Previous HitvelocityNext Hit-depth model and in getting the right Previous HitvelocityNext Hit-depth model we use depth-focusing Previous HitanalysisNext Hit. Previous HitMigrationTop in depth domain exhibit the real geology condition more than in time domain. At line ITS, the result shows the better image closed to real geology condition than in time domain.
