Poststack Time Migration Velocity Analysis by CRS Diffraction Stacking

The Common Reflection Surface stack provides the stacked section as well as kinematic wavefield attributes. We demonstrate on synthetic examples, how this attributes can be used to effectively separate reflected and diffracted energy. After separating the diffracted wavefield we introduce a technique for poststack time migration velocity analysis. Due to the application in the poststack data domain the presented procedure is stable and fast producing highly focused time migrated images.
