oa Role of Interfacial Rheological Properties of Oil/Water Systems in Mechanism and Design of EOR/IOR Technologies

Interfacial rheological properties of different Hungarian crude oil/water systems were determined in wide temperature and shear rate range and in the presence of inorganic electrolytes, tensides, alkaline materials and polymers. The detailed laboratory study definitely proved that the interfacial rheological properties are extremely sensitive parameters towards the chemical composition of immiscible liquids. Therefore, comparison and interpretation of the interfaciel rheological properties may contribute significantly to extension of the spectrum of the reservoir characterization, better understanding of the displacement mechanism, development of more profitable EOR/IOR methods, intensification of the surface technologies, optimization of the pipe line transportation and improvement of the refinery operations.
