Abstract

An efficient modeling technique is developed for transversely isotropic, inhomogeneous media using a mix of analytical equations and numerical calculations. The analytic equation for the raypath in a factorized transversely isotropic (FTI) media with linear velocity variation, derived by Shearer and Chapman, is used to trace rays between two points. In addition analytical equation for geometrical spreading in FTI media is developed that aids in preserving program efficiency; however, the traveltimes are calculated numerically. The method is generalized to treat general transversely isotropic (TI) media that are not factorized anisotropic inhomogeneous. -from Author
