Antenna operation for reservoir heating

A method for heating a subterranean formation, comprising:

• installing a radio frequency (RF) antenna in a hydrocarbon-bearing formation, wherein the RF antenna includes at least one passageway for fluid flow;
• circulating a preconditioning fluid through the at least one passageway of the RF antenna to decontaminate the RF antenna, wherein the preconditioning fluid comprises a hydrocarbon fraction, mineral oil, silicon oil, ester-based oil, or any combination thereof, and wherein the preconditioning fluid for decontaminating the RF antenna further comprises:
• from 10 to 5000 ppm of one or more dispersants;
• from 10 to 5000 ppm of one or more detergents;
• from 10 to 500 ppm of one or more demulsifying agents;
• and from 10 to 500 ppm of one or more oxygen scavengers;
• and
• transmitting electromagnetic energy to the decontaminated RF antenna to provide thermal energy to the hydrocarbon-bearing formation.
