In this paper, an inversion method for fracture-related layer properties based on elastic impedance data is presented. Firstly, qP-qP reflection coefficients between the two weakly anisotropic HTI half-space media is studied, after which the expression of reflection coefficients is linearized. Then, a simplified HTI elastic impedance formula is derived. Finally, a workflow for extracting fracture properties from elastic impedance data is proposed. Test on theoretical model and its synthetic seismic data shows that the proposed method obtains a reliable and expected result.
