Patent number: 7170294Abstract: A new application of electromagnetic tomography is described directly related to the efficient recovery of oil and gas as well the removal of unwanted liquids from subsurface formations. The process involves the deployment of both surface and a single borehole magnetic dipole structures used for both transmitting and receiving low frequency electromagnetic energy. The surface antenna consists of circularly concentric arrays of small receiving solenoid antennas and the downhole system consists of one or more solenoid antenna in a single borehole. The concentricity of the surface array is centered about or in proximity to the borehole axis. The electromagnetic field radiated by the downhole antenna is received by each surface antenna. The amplitude and phase of voltages and currents received by each surface antenna is electronically processed based on the theoretical processing principles similar to what has been recently established for electromagnetic impedance tomography (EMIT).Type: GrantFiled: January 19, 2006Date of Patent: January 30, 2007Assignee: KSN Energies, LLCInventor: Raymond S.

Patent number: 6440312Abstract: A system and method for separating oil from an oil tailing having water includes introducing the oil tailing within a chamber, and applying RF energy to the oil tailing at a temperature sufficient to convert the water to steam and to separate the oil from the tailing. The system allows removal of the water from the tailing followed by RF energy absorption by the tailing prior to substantial heat transfer to the surrounding mineral portion of the tailing. Among other advantages, the system produces tailings substantially devoid of oil, thereby allowing the tailing to be disposed of in an environmentally safe manner. The system is particularly advantageous for offshore drilling operations where storage and subsequent hauling of the oil tailings ashore for processing and disposal is expensive.Type: GrantFiled: May 2, 2000Date of Patent: August 27, 2002Assignee: Kai Technologies, Inc.Inventor: Raymond S.

Patent number: 6016452Abstract: A method and system for the delivery of radiofrequency energy to the tissue, particularly, the prostate, to alleviate the symptoms of BPH is disclosed. The system incorporates a bipolar or multipolar electrode array to create an electric field where the heat created is confined solely to a specific volume of the prostate gland and therefore the heated tissue is defined only by the electrode geometry. The bipolar electrode array provides a variety of three dimensional, symmetric heating patterns within the prostatic tissue depending on the relative electrode lengths and angular separation. The system provides precision tissue temperature and impedance measurements thereby enabling the surgeon to accurately predict heating pattern performance and tissue response to RF heating.Type: GrantFiled: March 19, 1997Date of Patent: January 18, 2000Inventor: Raymond S.
