An acid corrosion inhibitor is provided that is compatible with viscoelastic surfactants and useful for enhancing the production of hydrocarbon bearing formations. The viscoelastic surfactant can used in fracturing of subterranean formations penetrated by an oil or gas well or in connection with acidizing or other treatment processes. The acid corrosion inhibitor can include a viscoelastic surfactant and an active inhibition compound which can comprise a reaction product of thiourea, paraformaldehyde and acetophenone, or amines (linear or cyclic), amine quaternaries (linear or cyclic) or combinations or mixtures thereof.
