From the analysis of a multi-component seismic data from vertical seismic profiling (VSP) for frequency-dependent anisotropy, we find that shear-wave anisotropy as inferred from measured time delays between split shear-waves decreases systematically as frequency increases. Whilst in general, the polarizations of the fast split shear-waves remain constant for deep receivers, we notice systematic rotation...
There is relative motion and inertial coupling between solids and fluids during seismic and acoustic propagation in rocks with fluids. This inertial coupling is anisotropic because of the microvelocity anisotropy of the fluid relative to solid in an anisotropic medium. The Biot mechanism and the squirt-flow mechanism are the two most important mechanisms of solid/fluid interaction in rocks. We extend...
