Abstract
A tool (400) is disclosed for use in recovering gas from a gas well without the production of water as well. The tool (400) uses a member, such as plurality of vertically stacked balls (430) which are lighter than water to close a channel 422 when the water level (432) exceeds a certain level. As gas accumulates about the balls, the water level 432 will be moved downwardly, eventually causing the balls to move out of engagement with the seal surface (424), opening the channel (422) for passage of the gas upwardly for recovery. As the water level rises, the balls will again seal against the seal surface (424).
