Fracture Characterisation from Seismic Measurements

The current approach is to use the model of vertical or inclined fractures embedded in an isotropic, solid medium. The linear slip theory of Schoenberg and the Hudson’s penny-shape crack model are used to derive effective anisotropic properties of various fracture models, while modelling is conducted via exact anisotropic Zoeppritz equations. The polar representation of the AVO gradient, at constant incidence angles is one of the ways to assess the potential of azimuthal AVO analysis. Tests with field data are currently being conducted.
