Prestack Depth Migration
(PSDM) is a process in correcting data seismic by doing
migration
before stack in depth domain. PSDM is a powerful tool for complex geology
structure that has horizontal and vertical velocity variation. PSDM with finite difference
method has been done by iterative process of velocity-depth model and in getting the right
velocity-depth model we use depth-focusing analysis.
Migration
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.
