    摘要: A method of producing hydrocarbons from a subterranean reservoir comprises pre-heating by exposure to electromagnetic radiation from a electromagnetic radiation source, injecting through at least one injection well a solvent into the reservoir to dilute the hydrocarbons contained in the pre-conditioned portion, and producing through at least one production well a mixture of hydrocarbons and solvent. An apparatus for producing hydrocarbons from a subterranean reservoir comprises at least one radio frequency antenna configured to transmit radio frequency energy into a subterranean reservoir, a power source to provide power to the at least one radio frequency antenna, at least one injection well configured to inject a solvent from a solvent supply source into the subterranean reservoir to lower the viscosity of the hydrocarbons, and at least one production well configured to produce a mixture comprising hydrocarbons and solvent from the subterranean reservoir.

    摘要: A method for predicting hydrocarbon recovery in a subterranean formation may include generating pre-heating data associated with fracturing in a sample from the subterranean formation, heating the sample with RF power to cause additional fracturing in the sample, and generating post-heating data associated with additional fracturing in the sample after heating with RF power. The method may also include detecting change between the pre-heating data and post-heating data, and predicting hydrocarbon recovery from the subterranean formation based upon the detected change.

    摘要: A method for heating a hydrocarbon formation is disclosed. A radio frequency applicator is positioned to provide radiation within the hydrocarbon formation. A first signal sufficient to heat the hydrocarbon formation through electric current is applied to the applicator. A second or alternate frequency signal is then applied to the applicator that is sufficient to pass through the desiccated zone and heat the hydrocarbon formation through electric or magnetic fields. A method for efficiently creating electricity and steam for heating a hydrocarbon formation is also disclosed. An electric generator, steam generator, and a regenerator containing water are provided. The electric generator is run. The heat created from running the electric generator is fed into the regenerator causing the water to be preheated. The preheated water is then fed into the steam generator. The RF energy from power lines or from an on site electric generator and steam that is harvested from the generator or provided separately are supplied to a reservoir as a process to recover hydrocarbons.
