Abstract
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.
