Abstract

The importance of diving waves is being realized since they provide long model wavelength information, which can be utilized to invert the reflection wave information in a full waveform inversion (FWI). The factorized model is defined as a combination of vertical heterogeneity and constant anisotropy, and we define the closed form description of the diving wave traveltime. We propose analytical approximation for residual imaging moveout of diving waves in a factorized anisotropic medium. By using the classical semblance analysis, we estimate the optimal anisotropic parameters that can be later used for FWI initial model building.
