Patent number: 8643373Abstract: 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.Type: GrantFiled: November 10, 2010Date of Patent: February 4, 2014Assignee: Electro-Petroleum, Inc.Inventor: J.

Patent number: 8408287Abstract: A jumper providing electrical communication between two components of a producing well of an oil field. The jumper has two tubings for insertion in two components each with an anchor adapted to be rigidly mounted in its associated component. Each tubing has a centering device, consisting of a pair of rings surrounding the tubing and an array of bowed springs bridging between the rings and biased to bow outwardly into engagement with the bore of the associated component. One of the two rings is electrically and mechanically connected to the tubing, whereas the other ring is free to be displaced longitudinally of the tubing so that the outer diameter of the array of bowed el springs may expand or contract, as needed. Each bowed spring in the array is provided with supplemental electrical contacts to insure a path of electrical conductivity between the connected ring and the associated component through the bowed springs.Type: GrantFiled: June 3, 2010Date of Patent: April 2, 2013Assignee: Electro-Petroleum, Inc.Inventors: J.

Patent number: 7325604Abstract: A method of enhancing oil production from an oil bearing formation includes the steps of providing a first borehole in a first region of the formation and a second borehole in a second region of the formation. A first electrode is positioned in the first borehole in the first region, and a second electrode is positioned in proximity to the second borehole in the second region. A voltage difference is established between the first and second electrodes to create an electric field across the plugging materials. The electric field is applied to destabilize the plugging materials and improve oil flow through the formation.Type: GrantFiled: March 28, 2005Date of Patent: February 5, 2008Assignee: Electro-Petroleum, Inc.Inventors: J.

Patent number: 7322409Abstract: 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.Type: GrantFiled: January 31, 2005Date of Patent: January 29, 2008Assignee: Electro-Petroleum, Inc.Inventors: J.

Patent number: 6877556Abstract: 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.Type: GrantFiled: October 24, 2002Date of Patent: April 12, 2005Assignee: Electro-Petroleum, Inc.Inventors: J.

Patent number: 6075806Abstract: In an arc furnace or melter furnace employing concentric graphite inner and outer electrodes, 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 are disposed in the annular gap between the inner and outer electrodes. The spacers are held in position by arcuate recesses in the outer surface of the inner electrode or in the inner surface of the outer electrode. The electrodes may be constructed in segments that are assembled by threading one segment into another segment.Type: GrantFiled: December 23, 1998Date of Patent: June 13, 2000Assignees: Electro-Pyrolysis Inc, Svedala Industries Inc.Inventors: J.

Patent number: 5614077Abstract: An electrokinetic system and method are provided for removing charged species from a sample in which said charged species is commingled with at least one radionuclide. The apparatus comprises an anode compartment comprising an anode, a cathode compartment comprising a cathode, and a treatment zone in fluid communication with the anode and cathode compartments for containing the sample. The anode compartment, cathode compartment, and treatment zone are arranged so that a voltage gradient applied between the anode and the cathode induces an electrical current flow through the sample in the treatment zone. The current causes migration of the positively charged species in the sample toward the cathode and the negatively charges species toward the anode. A pH controller is provided for monitoring and adjusting acidity and basicity to facilitate the removal of salts while maintaining contaminants within the sample.Type: GrantFiled: April 10, 1995Date of Patent: March 25, 1997Assignees: Electro-Petroleum, Inc., Lehigh UniversityInventors: J.

Patent number: 5573339Abstract: Radiometer with a probe beam superimposed on its field-of-view for furnace temperature measurements. The radiometer includes a heterodyne millimeter/submillimeter-wave receiver including a millimeter/submillimeter-wave source for probing. The receiver is adapted to receive radiation from a surface whose temperature is to be measured. The radiation includes a surface emission portion and a surface reflection portion which includes the probe beam energy reflected from the surface. The surface emission portion is related to the surface temperature and the surface reflection portion is related to the emissivity of the surface. The simultaneous measurement of surface emissivity serves as a real time calibration of the temperature measurement.Type: GrantFiled: January 14, 1994Date of Patent: November 12, 1996Assignees: Electro-Pyrolysis, Inc., Massachusetts Institute of Technology, Battelle Memorial InstituteInventors: Paul P.
