摘要
Excessive water production from a producing gas well is substantially reduced by the injection of a hydrocarbon-diluted water-in-oil emulsion comprising a viscosifying polymer such as polyacrylamide, the injected emulsified polymer swelling on contact with connate water in the subsurface gas producing formation to restrict transfer of water therethrough toward the producing gas well.
