摘要
A method is discussed for obtaining resistivity values in a horizontal or highly deviated wellbore penetrating an anisotropic; formation layer. Multi-component data is obtained from the formation layer. An initial value of horizontal and vertical resistivity can be determined by using a whole space model and assuming an isotropic layer. Revised values of the vertical and horizontal resistivities are obtained through a first and second inversion process. A first inversion is performed on the horizontal resistivity, holding a value of vertical resistivity constant. A second inversion is performed on the vertical resistivity, holding a value of horizontal resistivity constant. These inversions are iterated until a desired convergence is achieved.
