oa Separation of anisotropy and inhomogeneity influence by the spectral analysis of azimuthal resistivity diagrams

The first aim of resistivitv survey is a study of any inhomogeneities. Frequently in practice the effect of anisotropy is displayed together with that of layering or inhomogeneities. It complicates data interpretation within the framework of anisotropic models, and distorts results of interpretation in the framework of layered or inhomogeneous media.
