ABSTRACT:
A core sample from a subterranean formation is shaped to provide a plurality of parallel, planar outer surfaces. Electrical resistivity is measured in each of the azimuthal directions through the core sample which are perpendicular to each of the pairs of parallel, planar outer surfaces for each of a plurality of differing fluid saturations within the core sample. A logarithmic plot is made of measured resistivity versus water saturation for each of the azimuthal directions through the core sample for which resistivity was measured. If the same logarithmic plot is obtained for all measured azimuthal directions, the core sample is identified as being electrically isotropic. If different logarithmic plots are obtained for at least 2 azimuthal directions the core sample is identified as being electrically anisotropic.
