FACTORS AFFECTING OIL VISCOSITY AND THE STUDY OF METHODS FOR REDUCING IT

In oil production, the high viscosity of crude oil negatively affects the production rate, causing serious problems. Numerous studies are aimed at assessing the properties of various grades of crude oil and their extraction technologies. The main reasons for high viscosity are the presence of solid particles, high concentrations of heavy fractions, and the formation of "water-in-oil" emulsions. This article discusses the mechanisms aimed at reducing the viscosity of oil with a high concentration of solid fractions, the mechanisms of formation and destabilization of emulsions, as well as methods for reducing viscosity.
