A Separately Determining Anisotropic Formation Parameter Method for Triaxial Induction Data

This letter describes a method to extract the unknown parameters of the formation using triaxial induction data based on the whole-space model. Two single-parameter coupled functions are constructed to determine the horizontal conductivity and the relative dip. After that, the vertical conductivity is solved analytically using another single-parameter function. The method is extremely fast and can be implemented for real-time processing and interpretation to allow decision making on the well site. The results can be further refined via postprocessing while the relative dip is required to be constant within an interval.
