    摘要: Provided are treatment fluids that comprise an aqueous based fluid, a water-soluble salt, and a methyl ester sulfonate surfactant, and associated methods. In one embodiment, a method of treating a subterranean formation is provided, the method comprising: providing a treatment fluid comprising an aqueous base fluid, a water-soluble salt, and a methyl ester sulfonate surfactant; and introducing the treatment fluid into a well bore that penetrates the subterranean formation. Also provided are methods of fracturing a subterranean formation, and methods of removing formation particulates from a well bore or a near well bore region. 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.

    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.

    摘要: Provided are treatment fluids that comprise an aqueous base fluid, and a methyl ester sulfonate surfactant, and associated diverting methods of use. In one embodiment, the present invention provides a method of treating a subterranean formation comprising: providing a treatment fluid comprising an aqueous base fluid, and a methyl ester sulfonate surfactant; introducing the treatment fluid into a portion of a subterranean formation; and allowing the treatment fluid to divert at least a portion of a second fluid to a different portion of the subterranean formation. Also provided are methods of diverting a fluid from a portion of a 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.
