Practical Approaches to the Common-Reflection Surface (CRS) Stack

Common-reflection surface stacking is a time-processing technique for seismic reflection data that improves signal-to-noise at the cost of along-dip resolution. The theory is based on summations across multi-dimensional pre-stack reflections, but the noise reduction benefits can be realized with a purely post-stack process. Dip and azimuth information derived from this post-stack process can yield an improved velocity analysis.
