A bstract Constant offset sections can be mapped to a fixed offset and compared in order to provide a method of velocity analysis. The direct mapping to zero offset prior to stack might provide an alternative processing procedure to NMO and stack. The main advantage of such a procedure would lie in the correct treatment of cross‐dips, but interpretational advantages might also follow from the performance of partial stacks biased to either high or low offset information.
