Abstract:
A method for forming an insulated conductor heater with a final cross-sectional area includes reducing a cross-sectional area of an insulated conductor assembly to form an insulated conductor heater with a final cross-sectional area. The insulated conductor assembly may have been previously treated with at least one combination of a cold working step and a heat treating step. Reducing the cross-sectional area of the insulated conductor assembly to form the insulated conductor heater with the final cross-sectional area may include cold working the insulated conductor assembly to further reduce the cross-sectional area of the insulated conductor assembly by at most about 20% of the cross-sectional area of the insulated conductor assembly after the at least one combination of the cold working step and the heat treating step has been completed.
