An Example of Integrated Use of Common Reflection Surface Stack and Pre Stack Depth Migration

3D Common Offset CRS for Data Pre-conditioning

“…Figure 1 shows a regularized before-stack dataset, which may be used for each kind of seismic processing, both in time and depth domain. Gentile et al (2008) presented an integrated approach for depth velocity model building, using ZO CRS results to facilitate the interpretation in areas with high-noise level and no event continuity. Although CRS provides a substantial contribution to the solution of that and other cases, it was clear that the CRS cannot completely exploit its potentiality since it is solely based on a global (stacked) data interpretation that cannot capture non-hyperbolic contributions on the whole traveltime.…”
