SYSTEM AND METHOD FOR GENERATION AND EXTRACTION OF FOSSIL FUEL AND HYDROGEN FROM A GEOLOGIC FORMATION WITH INCREASED ENERGY EFFICIENCY

Resumen de: US2025264091A1

A method for extracting a fuel from a geologic formation comprises heating a target volume in the geologic formation to generate the fuel via thermal conversion of a precursor material, thereby also heating a part of the geologic formation, extracting the generated fuel from the geologic formation; recovering heat from the geologic formation; and using the recovered heat for one or more of: heating the target volume, heating a different target volume, extracting the fuel, recovering the heat from the geologic formation, processing the extracted fuel, and converting the recovered heat into another form of storable energy.

EXTRACTION OF HEAT ENERGY FROM ACTIVE HYDROCARBON WELLS

Resumen de: US2025264251A1

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).
