Apparatus is provided for measuring resistivities along the length of a core sample of a porous rock under confining pressure and varying fluid saturations. A confining pressure sleeve surrounds the core sample. Resistivities are measured along the length of the core sample by a plurality of electrodes extending through such sleeve as fluid saturations vary.
