Abstract
Among the many embodiments provided by the invention, in one embodiment, a method is presented that comprises: providing a treating fluid comprising water, a charged polymer in an amount in the range of from about 2000 to about 20000 ppm, and a surfactant having a charge that is opposite to that of the charged polymer, the surfactant being capable of forming a micellar bond between a hydrophobic group on the polymer and a hydrophobic group on the same or an adjacent polymer molecule to form a crosslink; and placing the treating fluid into a well bore. Another embodiment provides a method that comprises: providing a viscosified treating fluid comprising: water; a charged polymer in an amount in the range of from about 2000 to about 20000 ppm; a surfactant having a charge that is opposite to that of the charged polymer; and at least one micellar association of between the surfactant with the charged polymer; and placing the viscosified treating fluid into a well bore.
