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： An apparatus for a coaxial transmission line is provided. The apparatus can include a first and a second section of a conductor of the coaxial transmission line and a connector for connecting the first and the second sections in end-to-end relation. Each of the first and the second sections of the conductor have an exterior lateral surface and an interior lateral surface. For inner conductors, the connector is connected to the interior lateral surfaces of the first and second sections of the conductor. For outer conductors, the connector is connected to the exterior lateral surfaces of the first and second sections of the conductor. The connector allows the inner and outer diameters of the annulus between the inner and outer conductors line to be substantially uniform along the length of the coaxial transmission line.

摘要： Systems and methods for controlling heating of a hydrocarbon medium using a signal generator and a load having frequency and time dependent impedance. A desired heating life cycle is determined. A current state is determined using a model of the medium and the load. A desired operational state is determined from the current operational state and the desired heating life cycle. The desired operational state is selected to maximize a fit between the desired operational state and the desired heating life cycle. Desired signal generator control settings are determined for the signal generator in order to achieve the desired operational state. An output signal is generated using the signal generator by applying the at least one desired signal generator control setting to the signal generator. The output signal is defined to excite the load and thereby heat the hydrocarbon medium.

摘要： An apparatus and method for electromagnetic heating of a hydrocarbon formation. The method involves providing a producer well, which defines a longitudinal axis, between at least a first and second transmission line conductor. At a reference location along the length of the longitudinal axis, the first and second transmission line conductors are laterally spaced from the producer well by a first and second reference distance, respectively. At a second location, the first and second transmission line conductors are laterally spaced from the producer well by a third and fourth distance, respectively. At least one of the third and fourth distances are greater than the first and second reference distances, respectively. Excitation of the transmission line conductors generates an electromagnetic field having a reference shape and a reference position at the reference location and at least one of a more elongated shape and a different position at the second location.

摘要： An apparatus for a coaxial transmission line is provided. The apparatus can include a dielectric member having an inner surface defining a bore along a longitudinal axis of an inner conductor of the coaxial transmission line; and a first conductive member mounted axially around the dielectric member and extending along the longitudinal axis. A cross-section of an outer surface of the first conductive member can define a first perimeter. A cross-section of an inner surface of the outer conductor of the coaxial transmission line can define a second perimeter. The first perimeter can be smaller than the second perimeter and thereby provide clearance between a portion of the outer surface of the first conductive member and the inner surface of the outer conductor of the coaxial transmission line when the apparatus is positioned in an annulus defined by the inner conductor and the outer conductor of the coaxial transmission line.
