Based on the low frequency approximation of TIWL response in a homogeneous, transversely isotropic conductive medium, Zhdanov et al. derived the analytic formula to extract the conductivity of the anisotropic formation, the borehole dip angle and tool azimuth from the response of TIWL. These can be used as the foundation of TIWL data interpretation.
