Abstract
A method for estimating vertical and horizontal resistivity values and vertical and horizontal dielectric constant values of a multi-layer, anisotropic subterranean formation includes acquiring electromagnetic propagation measurements of the subterranean formation and inverting the measurements using a one-dimensional formation model to compute the anisotropic resistivity and anisotropic dielectric constant values. The model includes a plurality of formation layers in which each of the formation layers has corresponding vertical and horizontal real conductivity and vertical and horizontal imaginary conductivity values.
