Hydrocarbon resource heating system including RF antennas driven at different phases and related methods

摘要

A system for heating hydrocarbon resources in a subterranean formation having spaced-apart wellbores therein aligned in a plane may include radio frequency (RF) antennas to be positioned within respective ones of the spaced apart wellbores aligned in the plane. The system may also include a plurality of discrete RF sources each coupled to one of the RF antennas and configured so that the RF antennas are driven at a same frequency as each other RF antenna but at different phases.

1. A system for heating hydrocarbon resources in a subterranean formation having a plurality of spaced-apart wellbores therein aligned in a plane, the system comprising:
a plurality of radio frequency (RF) antennas to be positioned within respective ones of the plurality of spaced apart wellbores aligned in the plane; and an RF source coupled to one said plurality of RF antennas defining a driven RF antenna with adjacent ones of said plurality of RF antennas each having a different length defining passive RF antennas and being configured so that said plurality of RF antennas operate at a same frequency but at different phases based upon each different length.
