A method of extracting heat from hydrocarbon production or injection wells involves passing heat exchanger tubing (6) 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 (6) may be delivered on coil tubing (13) into the production tubing (8) and anchored above the DHSV, in a retro-fit operation. Alternatively it may be installed in a sidetrack well (126) via a dedicated kick-off (124, 125). If installed at the completion of the well, the heat exchanger tubing (206) may be located in the annulus, mounted on the outside of the production tubing (208); in this event, the heat exchanger tubing may extend further into the well (beyond the DHSV) to, or even beyond, the production packer (231).
