Hydrocarbon resource recovery system including different hydrocarbon resource recovery capacities and related methods

An antenna configured to be positioned within a wellbore in a subterranean formation for hydrocarbon resource recovery, the antenna comprising:

• an electrically conductive well pipe configured to be coupled to a radio frequency (RF) source and configured to
• generate a higher electric field strength region in the subterranean formation having a higher electric field strength and a lower magnetic field strength, and
• generate a higher magnetic field strength region in the subterranean formation having a higher magnetic field strength and a lower electric field strength;
• said electrically conductive well pipe having a plurality of openings therein defining a hydrocarbon resource recovery capacity adjacent the higher electric field strength region that is different than a hydrocarbon resource recovery capacity adjacent the higher magnetic field strength region.

A method of recovering hydrocarbon resources from a wellbore in a subterranean formation containing hydrocarbon resources, the method comprising:

• positioning an antenna having a tubular shape with a plurality of openings therein defining a hydrocarbon resource recovery capacity in the wellbore;
• supplying radio frequency (RF) power to the antenna;
• generating a higher electric field strength region in the subterranean formation having a higher electric field strength and a lower magnetic field strength;
• and
• generating a higher magnetic field strength region in the subterranean formation having a higher magnetic field strength and a lower electric field strength;
• positioning the antenna so that the hydrocarbon resource recovery capacity adjacent the higher electric field strength region is different than a hydrocarbon resource recovery capacity adjacent the higher magnetic field strength region.
