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.

Abstract: PROBLEM TO BE SOLVED: To provide an electrokinetic system which can remove charged chemical species from a sample.
SOLUTION: The electrokinetic system comprises an anode compartment, a cathode compartment, a treatment zone (including a sample container and a chamber) which has been connected so that a fluid flows between the anode compartment and the cathode compartment, means for applying a voltage gradient across the anode compartment and the cathode compartment, and a pH controller. The chamber is provided between the anode compartment and the sample container and between the cathode compartment and the sample container. The chamber contains a porous matrix material for hindering the movement of a charged contaminant component and allowing charged chemical species to pass therethrough. Charged chemical species contained in the sample are moved due to the voltage gradient. The pH adjustment of the treatment zone accelerates the accumulation of contaminants in the porous matrix material and accelerates the separation of charged chemical species.

Abstract: A electrokinetic system (10) and method are provided for removing charged species from a sample (9) in which said charged species is commingled with at least one radionuclide. The apparatus comprises an anode compartment (11) comprising an anode (12), a cathode compartment (15) comprising a cathode (16), and a treatment zone (19) in fluid communication with the anode and cathode compartments (11, 15) for containing the sample (9). The anode compartment (11), cathode compartment (15), and treatment zone (19) are arranged so that a voltage gradient applied between the anode (12) and the cathode (16) induces an electrical current flow through the sample (9) in the treatment zone (19). The current causes migration of the positively charged species in the sample (9) toward the cathode (16) and the negatively charges species toward the anode (12). A pH controller is provided for monitoring and adjusting acidity and basicity. In carrying out the method of the present invention, a sample (9) of the contaminated waste to be treated is introduced into the treatment zone (19) of the electrokinetic system (10), a voltage gradient is applied between the anode (12) and the cathode (16), thereby inducing an electrical current flow through the sample (1); and monitoring and adjusting the pH of the system (10) to facilitate the removal of salts while maintaining contaminants within the sample (9).

Abstract: A system for producing gas from a gas hydrate formation includes a first electrode and a second electrode. The first electrode is disposed in proximity of a first region of the formation, and the second electrode is disposed within a second region of the formation. The second electrode is separated from the first electrode by an electro-conductive path through the formation. An extraction well extends within the formation and intersects the electro-conductive path. The well comprises one or more perforations in fluid communication with the formation. A voltage source is connected to the electrodes and operates to produce a voltage difference across the electrodes. A method for extracting gases from a gas hydrate formation includes the step of establishing a voltage difference across two or more electrodes in a hydrate formation to thermally react with the hydrate formation and release gas from the formation.
