| titleOfInvention | Method for terminating or reducing water flow in a subterranean formation |
| abstract | A method of conditioning well bores and reducing the deleterious effects of water production in a subterranean formation by placing an aqueous phase polymer and/or resin, which at a designated set up time, solidifies and blocks water conduits and establishes post treatment gas and oil permeability. Novel polymers and/or resins for use as a water barrier are typified by phenolformaldehyde containing 1-2 weight % of at least one of sodium bisulphite, sodium metabisulphite or mixtures thereof. The method includes selecting a well having sizable hydrocarbon reserves with a production history of decrease of oil or gas production with concurrent increase of water production. |
