Resumen de: WO2025179156A1
A method of extracting heat from hydrocarbon production or injection wells involves passing heat exchanger tubing down an active production or injection well and securing it. Heat from the formation or from fluids in the production tubing or annulus is extracted and returned to the surface to be used in various ways on a platform, e.g. heating accommodation or water supplies. The heat exchanger tubing may be delivered on coil tubing into the production tubing and anchored above the DHS V, in a retro-fit operation. Alternatively, it may be installed in a sidetrack well via a dedicated kickoff. If installed at the completion of the well, the heat exchanger tubing may be located in the annulus, mounted on the outside of the production tubing; in this event the heat exchanger tubing may extend further into the well to, or even beyond, the production packer.

Closed loop wellbore configurations with unrestricted geometry for accommodating irregular or challenging thermal gradients within a thermally productive formation are disclosed. A working fluid is utilized in the loop for extraction of thermal energy there from. The loop and the unrestricted geometry are achieved using magnetic ranging of independent drilling operations which intersect from an inlet well and outlet well to form an interconnecting segment. In conjunction with the directional drilling, conditioning operations are incorporated to condition the rock face, cool the entire system, activate the wellbore for treatment to optimize thermal transfer inter alia. The significant degree of freedom in wellbore configuration is further optimized by the absence of mechanical impediments such as casing or liners in the heat transfer areas.
