Abstract

We present new P- and SV-wave equations involving no acoustic approximation in TI media. They are derived by projecting the wavefield of elastic equations onto phase vector and its normal in the wavenumber domain, respectively. Both the P- and SV-wave equations have clear physical meaning and can be used for modeling and migration (e.g. RTM). Although strong anisotropy results in residual SV- or P-wave noise, we discuss a straightforward approach of replacing the source to suppress it. Impulse response and numerical examples on a 2D overthrust model validate the wave equations.
