Characterizing the kinematics of seismic waves in elastic vertical transversely isotropic (VTI)
media involves four independent parameters. To reduce the complexity, the acoustic …

The anisotropic characteristics of underground media play a crucial role in seismic wave
propagation and should be accounted for during seismic imaging. The least-squares …

Subsurface anisotropy is commonly induced by shale layers, aligned cracks, and fine
bedding and has a significant impact on seismic wave propagation. Ignoring anisotropic …

We have developed an explicit finite-difference modeling scheme for the scalar acoustic
wave equation in tilted transverse isotropic (TTI) media, which is computationally efficient in …

Anisotropic pseudo-acoustic forward modeling and migration imaging are critical for high-
precision seismic exploration. However, the wavefields simulated by the traditional coupled …

High-precision elastic reverse-time migration (ERTM) imaging has always been one of the
trends in the development of geophysics. However, current wavefield simulations using time …

The acoustic approximation, even for anisotropic media, is widely used in current industry
imaging and inversion algorithms mainly because P-waves constitute most of the energy …

Characterizing the kinematics of seismic waves in elastic orthorhombic media involves nine
independent parameters. All wave modes, P-, S1-, and S2-waves, are intrinsically coupled …

ABSTRACT P-wave extrapolation in anisotropic media suffers from SV-wave artifacts and
computational dependency on the complexity of anisotropy. The anisotropic …

Seismic anisotropy, characterized by direction-dependent seismic velocity and attenuation,
is a fundamental property of the earth, widely observed in field and laboratory …
