    摘要： Gellable treatment fluids containing a terpolymer that comprises 2-acrylamido-2-methylpropanesulfonic acid, acrylamide, acrylic acid monomer units can be used in various subterranean operations where it is necessary for the treatment fluid to remain in a gelled state for extended periods of time at high formation temperatures. Methods for treating a subterranean formation can comprise providing a treatment fluid comprising an aqueous carrier fluid, a crosslinking agent, a gel stabilizer, and a terpolymer that comprises 2-acrylamido-2-methylpropanesulfonic acid, acrylamide, and acrylic acid monomer units, or any salt thereof; introducing the treatment fluid into a subterranean formation; allowing the treatment fluid to form a gel in the subterranean formation; and breaking the gel after it has been in the subterranean formation for at least about one day.

    摘要： Treatment fluids comprising an aqueous base fluid, a viscosifying agent, and a compliant dual-functional additive are provided. The present invention provides methods of using the treatment fluids in subterranean formations. One example of a suitable method includes providing a fracturing fluid comprising an aqueous base fluid, a viscosifying agent, and a compliant dual-functional additive that acts as a fluid loss control agent and a breaker and introducing the fracturing fluid into at least a portion of a subterranean formation at a rate and pressure sufficient to create or enhance at least one or more fractures in the subterranean formation.

    摘要： Provided are treatment fluids that comprise an aqueous base fluid, an acid, and a methyl ester sulfonate surfactant, and associated methods of use. In one embodiment, the present invention provides a method of acidizing a subterranean formation comprising: providing a treatment fluid comprising an aqueous base fluid, an acid, and a methyl ester sulfonate surfactant; introducing the treatment fluid into a well bore that penetrates the subterranean formation; and allowing at least a portion of the treatment fluid to react with at least a portion of the subterranean formation so that at least one void is formed in the subterranean formation. In some instances, the treatment fluids exhibit viscoelastic behavior which may be due, at least in part, to the association of at least a portion of the methyl ester sulfonate surfactant into a plurality of micellar structures.
