The paper reports on the research results of the formation process of emulsions in paraffin and highly resinous oil varieties. The effect of the composition of resin-asphaltene components and aqueous phase content in oil on pour point, rheological properties, and the viscous flow activation energy of oil-in-water emulsions was demonstrated. As determined, large resistant globules of water were formed in oil-in-water emulsions where paraffin hydrocarbons, were prevailing; the pour point, viscosity, and the viscous flow activation energy were increased. Emulsions of highly resinous oils were characterised by the formation of structures with small globules of water, high viscosity and the low viscous flow activation energy. The power relationship of the size of water globules in oil-in-water emulsions on the ratio of the content of resin-asphaltene components and paraffin hydrocarbons was determined.
