A composition for inhibiting or preventing the formation of emulsions and asphaltic sludges in the presence of treating acids during the acid stimulation of hydrocarbon wells is provided. The composition includes an alkyl aryl sulfonic acid or salt thereof, an acetylenic alcohol, an alkyl diphenyl oxide sulfonic acid or derivative thereof, in an alkyl alcohol solvent. The disclosed compositions can be used in an acid treatment solution, such as 15% hydrochloric acid, to prevent and resolve live acid and spent acid emulsions for a wide range of crude oils.
