摘要： A system for heating a hydrocarbon containing formation is described. A conduit may be located in an opening in the formation. The conduit includes ferromagnetic material. An electrical conductor is positioned inside the conduit, and is electrically coupled to the conduit at or near an end portion of the conduit so that the electrical conductor and the conduit are electrically coupled in series. Electrical current flows in the electrical conductor in a substantially opposite direction to electrical current flow in the conduit during application of electrical current to the system. The flow of electrons is substantially confined to the inside of the conduit by the electromagnetic field generated from electrical current flow in the electrical conductor so that the outside surface of the conduit is at or near substantially zero potential at 25° C. The conduit may generate heat and heat the formation during application of electrical current.

摘要： Novel electrical heater which are self-regulating as a result of appropriate combination of a constant current or constant voltage power source with a resistive heating component and a temperature-sensitive component. Preferred heaters comprise a plurality of heating units, each of which heating units comprises a reactive component, a resistive heating component, and a temperature-responsive component. Self-regulation of the heater may be achieved in a number of different ways, including the use of employing a reactive component and a temperature-responsive component which form a combination exhibiting an impedance which changes with temperature. The temperature-responsive component can for example change in dielectric constant, or in permeability or in shape, or can effect changes in the frequencies inputted to the reactive component.
