Abstract

See full text

A system comprises an injection well in communication with an underground reservoir containing a native methane-containing solution at a first temperature, a production well in communication with the reservoir, a supply system providing a non-water based working fluid to the injection well at a second temperature lower than the first temperature, wherein exposure of the working fluid to the native fluid causes a portion of methane to come out of solution to form a production fluid of at least a portion of the working fluid and the portion of methane, and exposure to the first temperatures heats the production fluid to a third temperature higher than the second temperature, wherein the heated production fluid enters the production well, and an energy recovery apparatus in communication with the productions well for converting energy in the production fluid to electricity, heat, or a combination thereof.
