Abstract
A device for heating hydrocarbon resources in a subterranean formation having a wellbore therein may include a tubular radio frequency (RF) antenna within the wellbore and a tool slidably positioned within the tubular RF antenna. The tool may include an RF transmission line and at least one RF contact coupled to a distal end of the RF transmission line and biased in contact with the tubular RF antenna. The tool may also include a dielectric grease injector configured to inject dielectric grease around the at least one RF contact.
