Development of oil fields with high viscosity of oil significantly complicates its extraction and transportation. To reduce the viscosity, various physical methods of acting on oil are used, including such as treating with a magnetic field and the impact of shear rate (shear stress) by creating pressure oscillations in the well fluid. Magnetic processing is carried out by installing devices equipped with magnets inside the downhole equipment and in onshore pipelines. The duration of physical effects is determined empirically based on laboratory and industrial experiments. In this way, the actual development of a mathematical model that allows to establish the general laws of the viscosity evolution when exposed to physical fields to increase their application success. The purpose of this research work is to create a mathematical model of viscosity, which establishes the laws of the oil viscosity evolution over time when exposed to oil shear rate and magnetic field.
