ABSTRACT:
A method is described for circulating hydrostatically pressured or geopressured brines so that dissolved methane in the brines can be recovered within the wellpipe. All processes take place downhole or in the surrounding briny formations, and the circulation is powered wholly or in large part by the pressure on the brine and natural compressive forces in the formation.
