Abstract: An in-situ reactor with hydrologic cells is provided to facilitate recovery of metals such as gold from rocks, or purification of salts such as potassium or magnesium chloride formed by evaporation of brines, by injecting into a source aquifer a fluid, which flows through and reacts with the solids or host rock within the in-situ reactor and then flows into a sink aquifer, from it is drained or pumped out via an exhaust borehole into a plant or a facility for further chemical treatment.

Abstract: Fluid and/or heat are induced to flow from one natural or artificial undeound aquifer, which extends vertically, at an incline or horizontally, across a host-rock formation to a well. Alternatively, fluid and/or heat are induced to flow from a well across the host-rock formation to a natural or artificial aquifer. The aquifer and well constitute the polarities of a hydrologic cell, like the electrodes of a battery or electric cell. An aquifer can be formed by fracturing the host formation and by injecting proppants into the fracture. Fluid and/or heat is injected into the source of the hydrologic cell and is induced to flow across the hydrocarbon bearing host formation within the cell such that the displacement of the injected fluid or heat causes the hydrocarbon to flow into the sink of the hydrologic cell. Aquifer(s) or well(s) can serve as either the source or the sink of the hydrologic cell. At least one aquifer serves as one of the polarities of the hydrological cell.

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.
