terms:downhole_ground
Cable armor or a long electrode often attached to the logging cable some distance (perhaps 100 feet) above an electrical logging sonde, or hung just below the casing, used as the reference electrode instead of an electrode at the surface. Used in the case of bad SP interference from electrical surface facilities or telluric currents. See differential SP.
