Abstract: Methods of acidizing a subterranean formation penetrated by a wellbore that include the steps of (a) injecting into the wellbore at a pressure below subterranean formation fracturing pressure a treatment fluid having a first viscosity and including an aqueous acid and a gelling agent selected from the group consisting of Formulas I-XI and combinations thereof; (b) forming at least one void in the subterranean formation with the treatment fluid; and (c) allowing the treatment fluid to attain a second viscosity that is greater than the first viscosity.

Abstract: A method of reducing shear recovery time of a viscosifying surfactant fluid system that includes introducing a viscosifying surfactant fluid system into a subterranean formation, wherein the fluid includes a major portion of a surfactant and a hydrophobically-modified associative polymer in a concentration sufficient to shorten the shear recovery time of the fluid system compared to the shear recovery time of the fluid system without the polymer.
