Abstract
Abstract 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, water-soluble polymers, non-ionic tensides and alkaline materials. The detailed laboratory study definitely proved that the interfacial rheological properties are extremely sensitive parameters towards the chemical composition of immiscible formation liquids. Therefore, comparison and interpretation of the interfacial rheological properties may contribute significantly to extension of the weaponry of the reservoir characterization, better understanding of displacement mechanism, development of more profitable EOR/IOR methods, intensification of surface technologies, optimization of pipe line transportation and improvement of refinery operations. It was evidenced that the interfacial rheology is an efficient and powerful detection and differentiation technique, which may enhance our knowledge on formation, structure, properties and behavior of interfacial layers. Thus, it will probably accelerate significantly the progress not only in oil recovery but also in all areas of colloid science and technology.
