NUMERICAL INVERSION OF ELECTRIC LOGS IN ANISOTROPIC CLAY SEDIMENT INTERVALS
Up-to-date logging tools provide high-precision lateral-array responses. Numerical inversion can evaluate not only horizontal, but also vertical electrical resistivity of the rocks around the well. The inversion software designed (based on an axis-symmetric geoelectric, transversally isotropic simulation) and an interpretation procedure have been tested on the practical data measured in clay-caps and Bazhenov-suite intervals.
