Measurements of Shear-wave Azimuthal Anisotropy with Cross-dipole Logs


Three methods for analyzing azimuthal anisotropy from cross-dipole logs are applied to data from the Powder River Basin in Wyoming. These techniques are based on the phenomena of flexural wave splitting in anisotropic materials and are analogous to the techniques used for VSP data processing. The four-component cross-dipole logging data obtained with a… (More)
