Abstract
The development of a velocity model for Pre-Stack Depth Migration (PSDM) is usually based on its ability to produce a well focused image through the stacking of flat image gathers. Unfortunately, velocity model estimation is extremely non-unique and so additional constraints are needed to produce geologically reasonable results.
