摘要:
A method for using RF energy to facilitate the production of oil from formations separated from the RF energy source by a rock stratum comprises operating an antenna to transmit RF energy into a hydrocarbon formation, the hydrocarbon formation comprised of a first hydrocarbon portion above and adjacent to the antenna, a second hydrocarbon portion above the first hydrocarbon portion, and a rock stratum between the first hydrocarbon portion and the second hydrocarbon portion. The operation of the antenna heats water in the hydrocarbon formation to produce steam in the hydrocarbon formation, and the steam heats hydrocarbons in the hydrocarbon formation and fractures the rock stratum to produce fissures in the rock stratum. The heated hydrocarbons in the second hydrocarbon portion flows into the first hydrocarbon portion through the fissures in the rock stratum.

A dipole antenna may be created by surrounding a portion of the continuous conductor with a nonconductive magnetic bead, and then applying a power source to the continuous conductor across the nonconductive magnetic bead. The nonconductive magnetic bead creates a driving discontinuity without requiring a break or gap in the conductor. The power source may be connected or applied to the continuous conductor using a variety of preferably shielded configurations, including a coaxial or twin-axial inset or offset feed, a triaxial inset feed, or a diaxial offset feed. A second nonconductive magnetic bead may be positioned to surround a second portion of the continuous conductor to effectively create two nearly equal length dipole antenna sections on either side of the first nonconductive magnetic bead. The nonconductive magnetic beads may be comprised of various nonconductive magnetic materials, and preformed for installation around the conductor, or injected around the conductor in subsurface applications. Electromagnetic heating of hydrocarbon ores may be accomplished.

摘要:
An aspect of at least one embodiment of the present invention is a device for cracking heavy hydrocarbons. A linear applicator is positioned within heavy oil containing aromatic molecules. A radio frequency electrical current source is electrically connected to the applicator at a first connection point and a second connection point to create a closed electrical loop. The radio frequency source is configured to apply a signal to the applicator that is sufficient to create a magnetic field and an electric field relative to the axis of the linear applicator. The device also includes a chamber positioned around the applicator generally between the first connection point and the second connection point to concentrate the magnetic field within a region surrounding the applicator and containing the heavy hydrocarbons.
