Abstract
A system for heating a hydrocarbon resource in a subterranean formation having a wellbore extending therein may include a radio frequency (RF) source, an RF antenna to be positioned within the wellbore, and a magnetic amplifier to be positioned in the wellbore and configured to couple the RF source to the RF antenna so that the RF antenna supplies RF power to the hydrocarbon resource in the subterranean formation.
Claims11
A system for heating a hydrocarbon resource in a subterranean formation having a wellbore extending therein, the system comprising:
- a radio frequency (RF) source;
- a direct current (DC) source;
- an RF antenna to be positioned within the wellbore;
- and
- a magnetic amplifier to be positioned in the wellbore and configured to couple said RF source to said RF antenna with amplification based upon said DC source so that said RF antenna supplies RF power to the hydrocarbon resource in the subterranean formation;
- said magnetic amplifier comprising a core, a shield assembly surrounding said core, and an electromagnet surrounding said shield assembly.
A method for heating a hydrocarbon resource in a subterranean formation having a wellbore extending therein, the method comprising:
- coupling a magnetic amplifier to a radio frequency (RF) antenna, and positioning the magnetic amplifier and RF antenna within the wellbore so that the RF antenna is adjacent the hydrocarbon resource, the magnetic amplifier comprising a core, a shield assembly surrounding the core, and an electromagnet surrounding the shield assembly;
- coupling the magnetic amplifier to an RF source;
- and
- operating the RF source and the magnetic amplifier so that the RF antenna supplies RF power to the hydrocarbon resource in the subterranean formation.
