I. Product Introduction
CEA foaming agent is a zwitter-ion chemical product composed of several surfactants, having good resistance to acid, alkali, high salinity and high concentration of calcium and magnesium ions. It can form foams through reaction with air, nitrogen or carbon dioxide. Due to its strong foaming capacity, high foam stability, its capacity is superior to similar products and it has good compatibility with other chemical additives.

III. Application Method:
Mix the foaming agent with water by proportion (or add other materials simultaneously), then inject with gas in a certain proportion simultaneously or intermittently.
Ⅳ. Scope of Application:
It is mainly used for foam flooding in tertiary oil recovery, and also in many other areas of oilfield production, such as foam acidizing, foam drilling, foam flushing, profile control/water shutoff, and foam drainage gas recovery. It is especially suitable for conditions of strong acid, strong alkali, high salinity, and high contents of calcium and magnesium ions.
