Abstract
Disclosed is an apparatus for recovering gas from an underground source of gas and water and for disposing of water from the source into a porous stratum above the source. A casing having perforations at the level of the porous stratum extends from the surface into the source. A first mandrel inside the casing is above the perforations and a second mandrel inside the casing is below the perforations. Each mandrel has a first and a second passageway therethrough. A perforated tube connects the first passageways of the first and second mandrels and a bypass tube connects the second passageways of the first and second mandrels. A first tube extends from the surface to the first passageway of the first mandrel and a second tube extends from the first passageway of the second mandrel into the source. A sucker rod extends from the surface through the inside of the first, perforated, and second tubes into the source. A pump in the source is actuated by the sucker rod for pumping water up the tubes to a level above the perforations. There is a first seal between the sucker rod and the inside of the first tube or the perforated tube above the perforations, normally at the surface, a second seal between the first mandrel and the casing, and a third seal between the second mandrel and the casing.
