Poly(alkyenylamide)-polysaccharide hydrogels for treatment of subterranean formations

摘要

The present invention provides compositions including poly(alkyenylamide)-polysaccharide hydrogels for treating a subterranean formation and methods of using the same. In various embodiments, the present invention provides a method of treating a subterranean formation, 5 including obtaining or providing a composition including a poly(alkenylamide)- polysaccharide hydrogel. The method also includes placing the composition in a subterranean formation. In some embodiments, the pol(alkenylamide)- polysaccharide hydrogel is a polyacrylamide-alginate hydrogel.
