Accounting for tilted electrical anisotropy in numerical simulation and interpretation of resistivity logging data (analytical review based on national and foreign literature)

Features and main conclusions of publications devoted to the study of medium transverse-isotropic geoelectric models which are characterized by inclination of the electrical anisotropy axis relative to a logging tool are reviewed in this article. Such models can be defined either by horizontal and vertical conductivities (or their reciprocals, called resistivities) with a non-zero dip of a logging tool or by the conductivity tensor with the tilt of the principal axes.
