Seismic data processing in the elastic anisotropic model is complicated due to
multiparameter dependency. Approximations to the P-wave kinematics are necessary for …

Seismic-wave attenuation is an important component of describing wave propagation.
Certain regions, such as gas clouds inside the earth, exert highly localized attenuation. In …

An elliptical anisotropic medium is defined as a simplified representation of anisotropy in
which the anelliptic parameters are set to zero in all symmetry planes. Despite the fact that …

There are many non-hyperbolic moveout approximations for VTI media with various
accuracy claims. We perform an analytical and numerical comparison of the 11 moveout …

Anisotropy and absorption are critical to the modeling and analysis of seismic amplitude,
phase, and traveltime data. Neglecting any of these phenomena, which are often both …

Traveltime tomography using transmission data has been widely used for static corrections
and for obtaining near-surface models for seismic depth imaging. More recently, it is also …

The well‐known asymptotic fractional four‐parameter traveltime approximation and the five‐
parameter generalised traveltime approximation in stratified multi‐layer transversely …

The moveout approximations play an important role in seismic data processing. The
standard hyperbolic moveout approximation is based on an elliptical background model with …

In a transversely isotropic (TI) medium, the trade-off between inhomogeneity and anisotropy
can dramatically reduce our capability to estimate anisotropy parameters. By expanding the …

The parameterization of anisotropic models is very important when focusing on specific
signatures of seismic waves and reducing the parameter crosstalk involved in inverting …
