Murphy, B G

The problem of reduction in productivity in gas wells due to connate water reducing gas permeability about the well bore is overcome. Dry gas is injected into the production well in sufficient quantities to remove the majority of the water which restricts gas flow about the well. The dry gas is obtained from gas produced from a well completed in the formation at some distance from the well being dryed and stimulated. Gas produced is passed over a drying agent, compressed and injected into the production well so that the well bore in the vicinity of the formation is rendered free of water with a high permeability to gas resulting.
