Abstract
A system for recovery of hydrocarbons or thermal energy from host-rock fotions bearing coal, oil-shale, tar-sands or oil by use of a hydrologic cell which conveys a reacting fluid under pressure to a source-aquifer, thereafter extracting thermal energy or hydrocarbons from said host-rock, moving said hydrocarbons or thermal energy to said sink-aquifer and then removing the hydrocarbons or thermal energy to the surface for ultimate use.
