Product Description
Emulsified Acid Technology (EAT) is designed for use in carbonate acidizing and acid fracturing. It is an oil-external emulsion formed with a 70:30 hydrochloric acid-to-oil ratio, stabilized with an emulsifier JKN-AEM. EAT emulsion retards the acid reaction rate of 28% HCl approximately 10-15-fold. Even greater retardation (up to 40-fold) is achieved at lower acid concentrations.
Technical & Engineering Information
JKN-AEM is a good surface-active agent for stabilizing acid-internal and oil-external emulsions. It is applicable at wide temperature range from 60 to 350°F（16-177℃）. Typical acid-to-oil ratio for JKN-AEM application is 70/30 by weight percentage. Higher acid-to-oil ratio will increase friction pressure and lower ratio will decrease acid strength and capacity.
JKN-AEM is compatible with most additives in acid stimulation systems. However, additives such as non-emulsifying agents and corrosion inhibitors must be tested in the laboratory before using JKN-AEM.
