Abstract
A technique for recovering natural gas from geopressured brines contained in a first aquifer in which the brine is conveyed from the high pressure geopressured aquifer to an underground chamber at lower pressure at a location remote from the geopressured aquifer, the lower pressure within the chamber causing the gas to be released from the brine after entry into the chamber. The released gas is conveyed from the chamber to a suitable gas outlet for use while the brine within the chamber by virtue of its pressure is conveyed to a second upper level discharge aquifer at a location remote from the chamber.
