A system for heating hydrocarbon resources in a subterranean formation having a wellbore therein includes a coaxial transmission line, a balun, and a radio frequency (RF) antenna coupled together in series and configured to be positioned in the wellbore so that the RF antenna heats the hydrocarbon resources in the subterranean formation. The coaxial transmission line includes an inner conductor and an outer conductor surrounding the inner conductor. The balun includes an outer conductive sleeve having a proximal end coupled to the outer conductor of the coaxial transmission line and a medial portion coupled to the inner conductor of the coaxial transmission line. An inner tubular conductor extends longitudinally within the outer conductive sleeve between the outer conductor of the coaxial transmission line and the RF antenna. The balun also includes a ferrite body surrounding the inner tubular conductor at the proximal end.

A device for hydrocarbon resource recovery from at least one well in a subterranean formation may include a radio frequency (RF) source, a solvent source, and a double-wall structure coupled to the RF source to define an RF antenna within the at least one well to provide RF heating to the subterranean formation. The double-wall structure may absorb heat from adjacent portions of the subterranean formation. The double-wall structure may also include inner and outer walls defining a solvent passageway therebetween coupled to the solvent source. The outer wall may have a plurality of openings therein to eject solvent into the subterranean formation. The double-wall structure may transfer heat to the solvent so that the ejected solvent is in a vapor state.

A radio frequency applicator and method for heating a geological formation is disclosed. A radio frequency source configured to apply a differential mode signal is connected to a coaxial conductor including an outer conductor pipe and an inner conductor. The inner conductor is coupled to a second conductor pipe through one or more metal jumpers. One or more current chokes, such as a common mode choke or antenna balun, are installed around the outer conductor pipe and the second conductor pipe to concentrate electromagnetic radiation within a hydrocarbon formation. The outer conductor pipe and the second conductor pipe can be traditional well pipes for extracting hydrocarbons, such as a steam pipe and an extraction pipe of a steam assisted gravity drainage (SAGD) system. An apparatus and method for installing a current choke are also disclosed.

Extracting of Heavy Oil (Hydrocarbon) from Tar Sand and Oil Shale in deep reservoirs 7,000-12,000 feet below the ground surface by using Circular Waveguides Technology and Microwave Energy High Power System. Using Circular Waveguides as microwave energy radiator connects to the Microwave High Power System is the most practical method and provides a relatively cost-effective means of extract heavy oil from target Tar Sand or Oil Shale in deep reservoirs. This invention method can be applied for future new well bores that are in the plan to be drilled. It also can be used for existing un-use well bores that are being closed; waiting for cleaner new enhance oil recovery technology becoming available in order to reclaim of heavy oil without damaging the environment.
摘要:
This disclosure includes systems and methods for extracting hydrocarbons from a geologic structure. Some systems use or include a well-bore that extends at least partially through the geologic structure, a first electrode disposed within the wellbore, an ionically conductive medium in fluid communication with the first electrode, a second electrode in electrical communication with the first electrode, and a power source configured to establish an electrical current between the first and second electrodes to cause an electrochemical reaction. Some systems are configured to facilitate extraction of hydrocarbons from a geologic structure.
