Fracture Characterization with Azimuthal Attribute Analysis of PS-wave Data - Modelling and Application

We carry out azimuthal seismic anisotropy analysis of P- and PS-wave for fracture characterization with numerical modelling and a 3D3C dataset. Numerical results reveal that both the amplitudes and interval travel-time of the R-component of PS-wave can be used to infer fracture properties through ellipse fitting as that in azimuthal P-wave attribute analysis. In the real 3D3C data analysis, the fracture properties obtained from the azimuthal R-component analysis of the PS-wave data agrees with that inferred from the geological and logging information.
