subsurface formations exhibit directional dependence, or seismic anisotropy. On their way to …

Time-domain finite-difference modeling for attenuative anisotropic media

T Bai, I Tsvankin - Geophysics, 2016 - library.seg.org
Accurate and efficient modeling of seismic wavefields that accounts for both attenuation and
anisotropy is essential for further development of processing methods. Here, we present a …

Effect of fracture fill on frequency‐dependent anisotropy of fractured porous rocks

L Kong, B Gurevich, Y Zhang, Y Wang - Geophysical Prospecting, 2017 - earthdoc.org
In fractured reservoirs, seismic wave velocity and amplitude depend on frequency and
