ABSTRACT:
An improved method is provided for producing natural gas from wells where gas production has been hampered by the infiltration of water which had heretofore been deemed too expensive to remove when compared to the amount of gas produced from the well. The method includes lowering a conduit from the surface into the well to a depth the water level is to be lowered. Water in the well is allowed to flow into the conduit in a single direction only. A volume of refined natural gas is injected into the conduit below the water contained therein. The injected gas expands within the conduit lifting the volume of water to the surface. Water removed from the well is transported with the injected gas to a storage and processing facility. Lowering of the water level in the well reduces the hydrostatic pressure exerted upon the gas producing horizon to allow gas to flow into the well. Produced gas is transported along with the water and injected gas. This method and an apparatus for use in carrying out the method may also be used in newly drilled gas wells.
