Abstract
Summary
In this paper, we present an anisotropic AVO inversion method for the VTI media based on an improved form of Rüger’s equation. The AVO intercept, gradient and anisotropic P-wave velocity are inverted simultaneously. Synthetic data test demonstrates that this method provide accurate result of anisotropic P-wave velocity and more accurate AVO gradient than the isotropic inversion. We apply this method on a real seismic data; the anisotropy parameter e can be estimated according to the inverted anisotropic P-wave velocity.
