  A fracturing fluid comprising: water; a water-soluble salt; and a viscoelastic surfactant, wherein the viscoelastic surfactant: increases the viscosity of the fracturing fluid, wherein the viscosity is increased to at least a sufficient viscosity that proppant are suspended in the fracturing fluid; and is in at least a sufficient concentration such that the viscoelastic surfactant spontaneously forms micelles. A method of fracturing a subterranean formation comprising: introducing the fracturing fluid into a well, wherein the well penetrates the subterranean formation; and creating one or more fractures within the subterranean formation with the fracturing fluid.

  A treatment fluid for use in a subterranean formation penetrated by the wellbore of a well includes: (i) water; (ii) a strong acid; and (iii) a branched viscoelastic surfactant having a hydrophobic portion with a total of 16 to 20 carbons; wherein the pH of the treatment fluid is less than 0.5; and wherein the viscosity of the treatment fluid is less than 5 cP at 40 sec-1. A method of treating a zone of a subterranean formation penetrated by a wellbore includes the steps of forming the treatment; (B) introducing the treatment fluid through the wellbore into the zone; and (C) allowing time for the strong acid in the treatment fluid to spend in the formation. Such a treatment fluid shows good rheological properties at temperatures above 93°C (200°F).
