Abstract:
1. A gelled aqueous viscoelastic surfactant treating fluid comprising: an aqueous base fluid; a viscoelastic surfactant (VES) gelling agent in an amount effective to increase the viscosity of the aqueous viscoelastic surfactant treating fluid; and from about 2 to about 50 pounds per thousand gallons (pptq) (about 0.2 to about 6 kg/m as compared with an identical fluid absent the agent, where the solid, particulate dicarboxylic acid fluid loss control agent is insoluble in aqueous liquids and hydrocarbon liquids, but is soluble in mutual solvents and/or alcohol blends, and where the solid, particulate dicarboxylic acid agent has a formula molecular weight of from 146 to 400.
