method and apparatus for removing water from a gas well to permit efficient production of gas while protecting formation from introduced pressures . the apparatus comprises a check valve that seals the casing from production zone when hydrostatic pressure of water from production accumulates in casing above production perforations and checkvalue exceeds formation pressure . when the casing is sealed , a compressor pressurizes gas into the casing but not an exhaust conduit , the top of the casing being sealed around the exhaust conduit , permitting communication between the conduit and a suitable destination , such as via liquid separators on into sale pipeline . accumulated water is caused to flow into the bottom of the exhaust conduit and out at surface to collection . when pressure within the sealed casing to the top end of exhaust conduit is equalized , the checkvalve opens and regular production can resume .
