In this abstract, we discuss the implementation of a TTI reverse time migration. Also we
address several practical issues regarding numerical accuracy, stability and artifact removal …

Conventional modeling and migration for tilted transversely isotropic (TTI) media may suffer
from numerical instabilities and shear wave artifacts due to the coupling of the P-wave and …

Pseudo-acoustic wave equations are usually used in reverse-time migration (RTM) for TI
media. The acoustic wave equations for TTI media are much more complicated than those …

Reverse time migration (RTM) exhibits great advantages over other imaging methods
because it is based on computing numerical solutions to a two-way wave equation. It does …

In the implementation of TTI RTM, we meet stability problems and demands for speedup.
Staggered Fourier first derivative and linear interpolation improves stability and accuracy …

Seismic anisotropy in dipping shales results in imaging and positioning problems for
underlying structures. We develop a reverse-time anisotropic depth migration approach for P …

Anisotropy is a common phenomenon in subsurface strata and should be considered in
seismic imaging and inversion. Seismic imaging in a vertical transversely isotropic (VTI) …

We present an approach for P-wave modeling in inhomogeneous transversely isotropic
media with tilted symmetry axis (TTI media), suitable for anisotropic reverse-time migration …

In this paper we derive a stable second order wave equation for reverse time migration in
arbitrarily heterogeneous 3D orthorhombic media (ORT) with vertical and tilted symmetry …

R everse time migration (RTM) was first introduced in the early 1980s (Whitmore, 1983), but
was seemingly dormant until recent advances in computer hardware helped propel it onto …
