Abstract

A system for heating a hydrocarbon resource in a subterranean formation having a wellbore extending therein may include a radio frequency (RF) source, and a casing within the wellbore including electrically conductive pipes with a dielectric heel isolator coupled between adjacent electrically conductive pipes. Electrically conductive pipes from among the plurality thereof and downstream from the dielectric heel isolator define an RF antenna. The system may further include an RF transmission line extending within the casing and coupled between the RF source and RF antenna, a seal between the RF transmission line and adjacent portions of the casing adjacent the dielectric heel isolator to define an internal choke fluid chamber upstream of the seal, and an electrically conductive choke fluid contained within the internal choke fluid chamber.
