ABSTRACT:
Methods of treating a portion of a subterranean formation, comprising: providing an aqueous treatment fluid comprising water, and a friction reducing copolymer that comprises acrylamide and an acrylic acid ester; and introducing the aqueous treatment fluid into the portion of the subterranean formation. Methods of fracturing a subterranean formation comprising: providing an aqueous treatment fluid comprising water, and a friction reducing copolymer that comprises acrylamide and an acrylic acid ester; and introducing the aqueous treatment fluid into the subterranean formation at or above a pressure sufficient to create one or more fractures in the subterranean formation. Aqueous treatment fluids comprising: an aqueous fluid and a friction reducing copolymer that comprises acrylamide and an acrylic acid ester.
