Abstract:
(EN) An insulated (mineral insulated) conductor heater for heating a subsurface formation is disclosed. The heater may include a first elongated electrical conductor, a first electrical insulator at least partially surrounding the first elongated electrical conductor, a second elongated electrical conductor at least partially surrounding the first electrical insulator, a second electrical insulator at least partially surrounding the second elongated electrical conductor, and an electrically conductive sheath at least partially surrounding the second electrical insulator. The first elongated electrical conductor and the second elongated electrical conductor may be electrically coupled at an end of the heater distal from a surface of the formation. The first elongated electrical conductor and the second elongated electrical conductor may provide resistive heat output to heat at least a portion of the subsurface formation when electrical current is applied to the first elongated electrical conductor and the second elongated electrical conductor.
(FR) Cette invention concerne un dispositif de chauffage à conducteur isolé (à isolation minérale) pour chauffer une formation souterraine. Ledit dispositif de chauffage peut comprendre un premier conducteur électrique allongé, un premier isolant électrique entourant au moins partiellement le premier conducteur électrique allongé, un second conducteur électrique allongé entourant au moins partiellement le premier isolant électrique, un second isolant électrique entourant au moins partiellement le second conducteur électrique allongé, et une gaine électriquement conductrice entourant au moins partiellement le second isolant électrique. Le premier conducteur électrique allongé et le second conducteur électrique allongé peuvent être couplés électriquement à une extrémité du dispositif de chauffage à distance d'une surface de la formation. Le premier conducteur électrique allongé et le second conducteur électrique allongé peuvent fournir une sortie de chaleur résistive pour chauffer au moins une partie de la formation souterraine lorsqu'un courant électrique est appliqué au premier conducteur électrique allongé et au second conducteur électrique allongé.
