Patent ID: 8278252

Claim:
A method for treating a subterranean formation comprising: providing an aqueous viscoelastic surfactant treating fluid comprising: an aqueous base fluid; a viscoelastic surfactant (VES) gelling agent; and a particulate additive having a mean particle size of 100 nm or less, selected from the group consisting of alkaline earth metal oxides, alkaline earth metal hydroxides, alkali metal oxides, alkali metal hydroxides, transition metal oxides, transition metal hydroxides, post-transition metal oxides, and post-transition metal hydroxides, and mixtures thereof, where the transition metal in the transition metal oxide is selected from the group consisting of titanium and zinc and the post-transition metal in the post-transition metal oxide is selected from the group consisting of gallium, indium, thallium, lead and bismuth; injecting the aqueous viscoelastic surfactant treating fluid through a wellbore and into the subterranean formation; and treating the subterranean formation.
