Simplified Nonhyperbolic Moveout Formula for a Transversely Isotropic Medium



A new methodology of skew hyperbolic moveout analysis has been proposed to obtain the velocity model of reflection trafectories through an anisotropic medium. The original skew formula describes the trajectory in three velocity parameters. Conformation from the skew hyperbolic analysis suggested that one of the velocity parameters in the skew formula can be omitted/replaced. Furthermore, the moveout curve of nonhyperbolic analysis could also be analyzed by using only two velocity parameters. With one less parameter, we, therefore, call the modified skew formula a simplified nonhyperbolic moveout formula.
