A viscoelastic surfactant mixture (VESM) has been developed that is useful as a viscosity modifying additive for stimulating subterranean hydrocarbon containing formations. The VESM contains an amphoteric surfactant, an arylalkyl sulfonate cosurfactant and a polar solvent. The VESM may be employed as part of systems used in fracturing, acidizing, gravel packing and similar operations where a viscous fluid is required. The VESM can be applied over a wide range of temperatures and is especially useful if performance at elevated temperatures is required.
