An apparatus for hydrocarbon resource recovery from a subterranean formation includes a radio frequency (RF) source, an RF antenna to be positioned within the subterranean formation to deliver RF power to the hydrocarbon resource within the subterranean formation, and an RF transmission line extending between the RF source and the RF antenna. The RF transmission line may include RF transmission line sections coupled together in end-to-end relation. Each section may include an inner conductor, an outer conductor surrounding the inner conductor, and an outer load-carrying tubular member surrounding the outer conductor. A respective coupling assembly joins ends of adjacent sections together. Each coupling assembly may include an electrical coupler being fixedly connected to first ends of corresponding inner and outer conductors and being slidably connected to opposing second ends of adjacent inner and outer conductors, and a mechanical coupler connecting ends of adjacent load-bearing tubular members together.

Hydrocarbon resource recovery apparatus including RF transmission line and associated methods

A system for separating a hydrocarbon/water emulsion may include a radio frequency (RF) power source, an RF load, and a coaxial RF emulsion separator. The coaxial RF emulsion separator may include a coaxial input section coupled to the RF power source, a coaxial output section, and a coaxial separator section coupled in series between the coaxial input and output sections. The coaxial separator section may include an inner separator section conductor and an outer separator section conductor surrounding the inner separator section conductor and defining a separating chamber therebetween. The coaxial separator section may have at least one inlet port to introduce the hydrocarbon/water emulsion to the separating chamber and at least one outlet port to remove separated water and hydrocarbon from the separating chamber after exposure to RF power.

Hydrocarbon emulsion separator system and related methods

A radio frequency (RF) coaxial transmission line to be positioned within a wellbore in a subterranean formation may include a series of coaxial sections coupled together in end-to-end relation. Each coaxial section may include an inner conductor, a dual-wall outer conductor surrounding the inner conductor, and a dielectric therebetween. Each of the dual-wall outer conductors may include an outer wall and an inner wall spaced apart therefrom defining a fluid passageway. Each coaxial section may further include a threaded endpiece coupled to each opposing end of the dual-wall outer conductor and having threads to define an overlapping mechanical threaded joint and an electrical joint with an adjacent threaded endpiece.

RF coaxial transmission line for a wellbore including dual-wall outer conductor and related methods

A hydrocarbon resource recovery apparatus for a subterranean formation having a wellbore extending therein includes a radio frequency (RF) power source, a gas source, and an RF antenna within the wellbore. An RF transmission line extends within the wellbore between the RF power source and the RF antenna and is coupled to the gas source to be cooled and/or pressure balanced by a flow of gas therefrom. At least one of the RF antenna and RF transmission line define a gas lift passageway coupled to the gas source to lift hydrocarbon resources within the wellbore.

Combined RF heating and gas lift for a hydrocarbon resource recovery apparatus and associated methods

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.

Method for hydrocarbon recovery with change detection and related apparatus

A hydrocarbon resource recovery apparatus for a subterranean formation having a wellbore extending therein includes a radio frequency (RF) power source, a dielectric fluid source, and an RF antenna within the wellbore. An RF transmission line extends within the wellbore between the RF power source and the RF antenna and is coupled to the dielectric fluid source to be cooled and/or pressure balanced by a flow of dielectric fluid therefrom. A hydrocarbon resource recovery pump is within the wellbore and is also coupled to the dielectric fluid source to be powered by the flow of dielectric fluid therefrom.

Combined RF heating and pump lift for a hydrocarbon resource recovery apparatus and associated methods

A radio frequency (RF) antenna assembly to be positioned within a wellbore in a subterranean formation for hydrocarbon resource recovery may include a series of tubular conductors coupled together in end-to-end relation. Each tubular conductor may include a dual-wall conductor defining an RF antenna. The dual-wall conductor may include an outer wall and an inner wall spaced inwardly therefrom to define an outer fluid passageway. The RF antenna assembly may further include an RF transmission line extending within at least some of the tubular conductors.
