ABSTRACT:
Viscoelastic surfactant fluids, and methods of using such fluids and controlling the viscosity thereof. In one embodiment, the methods of the present invention comprise: providing a viscoelastic surfactant fluid that comprises an aqueous-base fluid, and a surfactant; providing a metal ion having at least two oxidation states wherein at least one of the oxidation states interferes with the ability of the surfactant to form a viscosifying micelle, wherein at least a portion of the metal ion is present in an oxidation state that interferes with the ability of the surfactant to form a viscosifying micelle; allowing the metal ion to interact with viscoelastic surfactant fluid so as to decrease the ability of the surfactant to form a viscosifying micelle; and introducing the viscoelastic surfactant fluid into at least a portion of a subterranean formation.
