Abstract: 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.

The apparatus includes two or more wellbore casings positioned within two or more wellbores. The two or more wellbores extend from a proximal end at the ground surface to a distal end at the underground hydrocarbon formation. Each of the two or more wellbore casings have a proximal portion and a distal portion. The two or more wellbores are in proximity to one another at a junction. The apparatus also includes a first electrical connection between the proximal portions of the two or more wellbore casings for grounding the two or more wellbore casings and a second electrical connection between the distal portions of the two or more wellbore casings. The second electrical connection is located at the junction and provides a short circuit that reduces current traveling on the two or more wellbore casings to the ground surface.

Abstract: 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.

Abstract: Systems and methods for asynchronous data communication are disclosed. The system includes one or more peripheral devices, a processing device, and one or more communication channels. Each peripheral device includes a peripheral clock and a quantizer. The processing device is remotely located from each peripheral device and includes a processor clock that is asynchronous with at least one peripheral clock, an analog continuous time filter, and an analog-to-digital converter. The analog continuous time filter filters one or more quantized signals generated by the one or more peripheral devices to generate one or more filtered signals. The analog continuous time filter has a filter bandwidth corresponding to a signal bandwidth of one or more analog time varying signals represented by the one or more quantized signals. The analog-to-digital converter generates one or more converted signals by sampling the one or more filtered signals based on a processor clock signal.

Abstract: 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.
