A method of heating a fluid which can be, for example, molten sodium, in a dry 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 steam making, preheating of refinery streams such as crude oil feed to distillation units, salt evaporation, etc.
