Abstract
An exposed resistive heating element is coupled to an electric power supply. The exposed resistive heating element is malleable such that it can be wrapped around a component to be heated. A controller is coupled to the power supply and the exposed resistive heating element. The controller is configured to regulate current exchanged between the exposed heating element and the electric power supply.
Claims6
A method comprising:
- receiving current by an exposed resistive heating element encircling a tubular;
- and
- heat-treating the tubular, by the exposed heating element, responsive to the received current, wherein the tubular comprises a wellhead and an uphole end of well casing protruding from a subterranean formation.
Dependencies are inferred from the claim text.
