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 velocity variation. PSDM with Previous HitfiniteNext Hit Previous HitdifferenceNext Hit method has been done by iterative process of velocity-depth model and in getting the right velocity-depth model we use depth-focusing analysis. 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.
