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...http://www.google.es/patents/US4924187?utm_source=gb-gplus-sharePatente US4924187 - Method for measuring electrical anisotrophy of a core sample from a subterranean formation
