Abstract: An electrode for enhancing electrical conductivity between an oil or gas field downhole and the surrounding formation. The electrode may serve as a cathode to cooperate with a remote anode to produce an electric field through the formation. The electrode has an electrically conductive, elongated body with a proximal end adapted to be inserted into the production pipe and a distal end adapted to project into the formation. The body of the electrode has a series of radially-projecting flexible filaments. The filaments are composed of an electrically conductive material and are supported by the body so as to be electrically charged. At least one of the filaments project outwardly into engagement with the wall of the downhole. The filaments also project radially outward into the consolidated formation.

Abstract: A method is provided for recovering oil from a subterranean oil-bearing formation. One or more pairs of electrodes are inserted into the ground in proximity to a body of oil in said formation. A voltage difference is then established between the electrodes to create an electric field in the oil-bearing formation. As voltage is applied, the current is manipulated to induce oxidation and reduction reactions in components of the oil. The oxidation and reduction reactions lower the viscosity in the oil and thereby reduce capillary resistance to oil flow so that the oil can be removed at an extraction well.

Abstract: In an arc furnace or melted furnace employing concentric graphite inner and outer electrodes (30, 20), the accumulations of tolerances, distortion and mechanical forces can cause a loss of concentricity leading to reduced performance and eventually to electrode degradation. To avoid that condition, a plurality of insulating spherical or cylindrical spacers (42, 44, 46, 48) are disposed in the annular gap (40) between the inner and outer electrodes (30, 20). The spacers (42, 44, 46, 48) are held in position by arcuate recesses (43, 45, 47, 49) in the outer surface of the inner electrode or in the inner surface of the outer electrode (20). The electrode may be constructed in segments (22, 24, 26 and 32, 34, 36) that are assembled by threading one segment into another segment.
