The amplitude variation with azimuth (AVAz) is commonly used to predict subsurface
fracture properties. Published analyses demonstrate the ambiguous characterization from …

Fracture-induced azimuthal anisotropy of seismic waves has useful applications in the
characterization of hydrocarbon reservoirs as well as the overburden. Existing theories face …

Reflection and transmission (R/T) responses characterize the energy distributions for
incident and generated waves across the subsurface interface. The R/T coefficients are …

Detection of fracture properties can be implemented using azimuth-dependent seismic
inversion for optimal model parameters in time or frequency domain. Considering the …

Seismic velocity anisotropy measurements are made of a fractured metamorphic formation
from the 2.5-km-deep International Continental Scientific Drilling Programme (ICDP) …

Such reservoir rocks as tar sands are characterized by significant attenuation and, in some
cases, attenuation anisotropy. Most existing attenuation studies are focused on plane-wave …

With the incident P-wave, we derive approximate formulas for amplitudes and polarizations
of waves reflected from and transmitted through a planar, horizontal boundary between an …

This paper illustrates the efficiency of vertical seismic profiling (VSP) for the investigation of
dipping and hydraulically conductive structures affecting a granitic basement covered by …

We propose a robust approach for the joint inversion of PP‐and PSV‐wave angle gathers
along different azimuths for the elastic properties of the homogeneous isotropic host rock …
