ABSTRACT:
An in situ heat exchange process for heating an organic fluid, which can be, for example, a normally liquid hydrocarbon having from 4 to 10 carbon atoms, in a geothermal reservoir formation penetrated by an injection well and a production well comprising injecting the said fluid into the formation via the injection well, forcing the fluid through the formation with simultaneous heating and finally recovering the heated fluid via the production well. Utilizing heat exchangers at the surface, the heated fluid may be employed to supply process heating requirements for such diverse operations as preheating of refinery streams as exemplified by crude oil feed to distillation units, for salt evaporation, etc. or the heated fluid, preferably after removal of any brine derived from the geothermal formation, may be employed in gaseous form to operate turbine generators.
