Abstract
In this case study we used three different velocity estimation methods, SIVA/RAYMAP (Sierrat tm) velocity analysis package, focusing analysis, and residual velocity analysis, to build velocity models for 3D prestack depth migration. The first two methods are more interpretation oriented than the last one. The imaging results from 3D Kirchhoff prestack depth migration from these three different models are discussed in this paper.
