Surfactants for hydraulic fractoring compositions

摘要: Viscoelastic surfactant based aqueous fluid systems are described that useful in fracturing subterranean formations penetrated by a wellbore. The preferred compositions contain quaternary ammonium salts wherein the long chain alkyl substituent contains about 3% or less of groups containing 18 carbon atoms. amount intermediate compounds composition is than 1%. can be used conjunction with an inorganic water soluble salt such as chloride potassium chloride, and organic stabilizing additive.
