Abstract:

The stability of different crude oil emulsions from ASP flooding production well is studied by the method of a stirred tank. The demulsifying of crude-oil emulsion by different demulsifying agents is discussed. The breakage of the crude oil emulsions from the well PO11 by the different types and concentrations of the emulsifying agents is also discussed. The breaking mechanism of the demulsifying agent is described microscopically.

Key words: Crude oil emulsion, Demulsifying agent, Demulsifying;Interfacial film, Liquid membrane, Initial breakage rate
