Title: Joint used for coupling long heaters

Abstract

Systems for coupling ends of elongated heaters and methods of using such systems to treat a subsurface formation are described herein. A system may include two elongated heaters with an end portion of one heater abutted or near to an end portion of the other heater and a core coupling material. The core coupling material may extend between the two elongated heaters. The elongated heaters may include cores and at least one conductor substantially concentrically surrounds the cores. The cores may have a lower melting point than the conductors. At least one end portion of the conductor may have a beveled edge. The gap formed by the beveled edge may be filled with a coupling material for coupling the one or more conductors. One end portion of at least one core may have a recessed opening and the core coupling material may be partially inside the recessed opening.
