摘要： This invention relates to a method for generating steam downhole. The proposed device is an electric steam generator with heating elements installed on the walls of internal communicating tortuous pipes in a cylindrical heating chamber with winding passage of water-steam mixture for achieving overheated steam condition. The heating elements are made of a high electrical resistance alloy to ensure the conversion of water injected from the surface to steam or high temperature superheated steam for injection into the reservoir under pressure.

摘要： An apparatus and method for electromagnetic heating of a hydrocarbon formation. The method involves providing electrical power to at least one electromagnetic wave generator for generating high frequency alternating current; using the electromagnetic wave generator to generate high frequency alternating current; using at least one pipe to define at least one of at least two transmission line conductors; coupling the transmission line conductors to the electromagnetic wave generator; and applying the high frequency alternating current to excite the transmission line conductors. The excitation of the transmission line conductors can propagate an electromagnetic wave within the hydrocarbon formation. In some embodiments, the method further comprises determining that a hydrocarbon formation between the transmission line conductors is at least substantially desiccated; and applying a radiofrequency electromagnetic current to excite the transmission line conductors. The radiofrequency electromagnetic current radiates to a hydrocarbon formation surrounding the transmission line conductors.

摘要： A downhole tool includes a body including a microwave generator, a susceptor shell connected to the body, and a thermometer connected to the body. The susceptor shell includes a wall made of a susceptor material and a cavity formed between the wall and the body. A system includes a well extending from a surface, a microwave heating tool positioned in the well, and an electrical cable extending from a power source at the surface to the microwave heating tool. A method of treating condensate buildup in a well includes lowering a microwave heating tool into the well to a treatment zone including accumulated condensates, providing power to the microwave heating tool via an electrical cable, increasing a temperature of the treatment zone to an elevated temperature using heat generated by the microwave heating tool, and removing the accumulated condensates in the treatment zone.

摘要： The present invention concerns a device for pulsed electric discharge in a liquid comprising a control module configured to control a voltage generator such that the voltage generator applies a predetermined heating voltage setpoint between electrodes during a heating period until a pulsed electric discharge is obtained between the electrodes, in order to measure the breakdown voltage during the pulsed electric discharge, in order to estimate the quantity of energy supplied to the liquid during the heating period, referred to as the “quantity of heating energy”, from the predetermined heating voltage setpoint and the measured breakdown voltage, and in order to determine a new heating voltage setpoint to apply between the electrodes of the at least one pair of electrodes at the next pulsed electric discharge based on the estimated quantity of heating energy and a predefined breakdown voltage setpoint.

摘要： Systems and methods for deployment of electric-based fracturing tools in vertical wells are disclosed. A method of electric-based fracturing may include lowering an electrical stimulation tool into a wellbore using a drill pipe and isolating a lower portion of the wellbore that is downhole from an upper portion of the wellbore. The electrical stimulation tool may be disposed in the lower portion of the wellbore. A system for electric-based fracturing may include an isolation mechanism and an electrical stimulation tool. The isolation mechanism may be configured to expand from a retracted configuration spaced from an interior surface of a wellbore to an expanded configuration in contact with the inner surface of the wellbore. The electrical stimulation tool may be operatively coupled with the isolation mechanism and may be configured to be disposed distally relative to the isolation mechanism when positioned in the wellbore.
