The stress-dependent wave reflection and transmission (R/T) coefficients for the layered
transversely isotropic media with a vertical symmetry axis (VTI) are seldom investigated in …

SUMMARY A detailed knowledge of wave reflectivity parametrization for non-welded
interface plays an important role in fracture characterization and reservoir prediction …

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

Most fractured reservoirs are two‐phase media, that is, mixture of solid matrix and void. It
contains rock skeleton and fractures or pores filled with oil, gas and water. These fractures …

In this work, we propose a phase delay approach to estimate the normal and shear fracture
compliances utilizing refracted P-and S-waves from full-waveform sonic (FWS) log data …

To quantitatively image fractures with high resolution, we have developed an elastic least-
squares migration (LSM) algorithm coupled with linear-slip theory, which accurately …

Seismic wave propagation across a fracture is represented by a nonwelded interface or the
linear-slip boundary condition. The normal and tangential fracture compliances control the …

In the process of seismic wave propagation, the presence of fractures will cause a seismic
wave response associated with fracture compliance. Full waveform inversion (FWI) is an …

Single-well reflection imaging using sonic logging data successfully locates fine-scale
structures around a borehole including fractures. In order to achieve accurate and …
