Abstract
Methods of forming one or more fractures in a subterranean formation penetrated by a well bore. The methods generally include providing a treating fluid that comprises water and one or more sulfonated gelling agent polymers, wherein the one or more sulfonated gelling agent polymers comprise a sulfonated synthetic polymer selected from the group consisting of sulfonated polyvinyl alcohol, sulfonated polyacrylate, sulfonated polyacrylamide/acrylic acid copolymers, and any combination thereof; and introducing the treating fluid into the subterranean formation. The treating fluid may be placed at a pressure sufficient to create or extend fractures within the subterranean formation.
