EFFECTIVE SOLVENT EXTRACTION SYSTEM INCORPORATING ELECTROMAGNETIC HEATING

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.
