The first contribution of CRS attributes lies on initial depth model building. The CRS tomographyic inversion can be easily appended to Dix inversion resulting in a initial model with better correspondence with the subsurface structures. A poststack depth migration of CRS stack volume also yields a higher quality initial depth image, fundamental for starting salt body delimitation. The use of CRS attributes for generating CRS gathers provide higher quality data for PSDM.
