Abstract
Summary
We introduce an approach to perform a model based PP and PS registration in depth domain which involves converting the RMS time model to the depth model and performing PSDM. We have developed a GUI tool for depth model building and a PSDM tool which is based on the ray-tracing method and Kirchhoff summation. This approach is applied to a real 2D dataset. Time processing is applied to the PP and PS waves to obtain time images and RMS velocity models separately. Then the depth models are obtained for the PP and PS waves. For PS waves, we build the depth model as close to the P wave depth model as possible. Finally, we apply the prestack depth migration to produce migrated depth images. The results show that the events in PP and PS depth images are well correlated. The model building in this approach is straightforward and this approach is practical.
