ABSTRACT:
For use in a field having a plurality of interspersed injection and production wells that extend to a mineral bearing formation, a system for extracting the mineral from the formation having a jet pump system for each production well, each pump system having a power fluid inlet and a production fluid outlet at the earth's surface, a bottom hole fluid inlet, a solvent reservoir at the earth's surface providing a source of liquid solvent and reservoir having connection to each of the injection wells by which solvent is conveyed to the mineral producing formation to produce a bottom hole reservoir of mineral laden bottom hole fluid, a power fluid reservoir at the earth's surface, a high pressure pump at the earth's surface connected between the power fluid reservoir and the power fluid inlet of each of the jet pump systems for moving power fluid through the jet pump systems to draw in bottom hole fluid that is mixed with the power fluid to provide production fluid that is moved to the earth's surface; and a mineral extraction station at the earth's surface that receives the production fluid and by which mineral is extracted and that provides recycled fluid that is conveyed to the power fluid reservoir.
