The pure P-wave equation for modelling and migration in tilted transversely isotropic (TTI)
media has attracted more and more attention in imaging seismic data with anisotropy. The …

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 …

In this paper, a pure P wave equation for an acoustic 2D TTI media is derived. Compared
with conventional TTI coupled equations, the resulting equation is unconditionally stable …

The anelasticity and anisotropy widely exist in real subsurface media. Strong anelasticity will
lead to phase dispersion and amplitude attenuation during seismic wave propagation …

Anisotropic reverse-time migration (RTM) yields more accurate images for subsurface
medium than isotropic migration. However, conventional qP-wave (quasi-P-wave) RTM in …

Abstract We present a Graphics Processing Units (GPU) implementation of time gating
based reverse time migration (TG-RTM) which uses the pseudospectral time-domain (PSTD) …
