Methods for selective plugging
Patent
·
OSTI ID:6555818
Methods and compositions are described for selectively plugging the water-rich strata of subterranean formations, including the injection into the formation of a water-soluble, oil-insoluble soap or ester. The soap or ester chemically reacts in the formation, either with reactants already in the formation or reactants which may be injected along with or prior to the soap or ester, to produce a water-insoluble, oil-soluble product which is effective to selectively plug the water-rich strata over a relatively long distance and over a relatively long period of time.
