发明名称 Methods for reducing the viscosity of treatment fluids comprising diutan
摘要 Methods are provided that include a method comprising providing a treatment fluid comprising a base fluid and a gelling agent that comprises a diutan composition; providing a breaker that comprises an acid composition; allowing the breaker to interact with the treatment fluid; and allowing the viscosity of the treatment fluid to decrease. In some embodiments, the treatment fluid may comprise a base fluid, a gelling agent that comprises a diutan composition, and a breaker that comprises an acid composition. In some embodiments, the treatment fluid may be introduced into a portion of the subterranean formation at or above a pressure sufficient to create or enhance one or more fractures in the portion of the subterranean formation. Additional methods are also provided.
