Abstract

Numerical simulations using low order approximations of the full Zoeppritz equations were performed on anisotropic parameters derived from the Sydney basin and the North West Shelf region. The resultant amplitude coefficients were then displayed in full azimuths in which a lineation indicates abnormalities caused by the fractured media. Our studies show that amplitude variations with offset and azimuth (AVAz) depend not only on fracture orientation, but also on impedance differences of P- and S-waves in the fractured media.
