Abstract
Dip‐moveout (DMO) velocity analysis (VA) may be performed in several ways. Using the Fourier transform‐based DMO techniques (Hale 1984, Notfors and Godfrey 1987, Liner and Bleinstein 1988), VA is done iteratively where a sequence of VA, normal moveout (NMO), DMO, inverse NMO, and a second VA yields an estimate of the DMO velocities. Using an integral method for application of a DMO process, Forel and Gardner (1988) proposed a way for performing VA by transforming the data into the [Formula: see text] domain, where DMO velocities are obtained by any common VA technique. In another work, carried out by Chon and Gonzalez (1987) a velocity‐sensitivity analysis was added to a Kirchhoff integral DMO algorithm.
