Abstract

A system for heating a hydrocarbon resource in a subterranean formation having a wellbore extending therein may include a radio frequency (RF) antenna configured to be positioned within the wellbore, an RF source, a cooling fluid source, and a transmission line coupled between the RF antenna and the RF source. A plurality of ring-shaped choke cores may surround the transmission line, and a sleeve may surround the ring-shaped choke cores and define a cooling fluid path for the ring-shaped choke cores and in fluid communication with the cooling fluid source.
