Study of oil properties under thermal, electrostatic, and electromagnetic influences

The development of effective and environmentally friendly ways to reduce oil viscosity is an urgent task for the oil industry. The purpose of the work is to study the properties of oil under thermal, electrostatic and electromagnetic influences. The viscosity of the oil was analyzed using an original experimental setup that allows thermal, electrostatic, and electromagnetic fields to be created in a certain volume. The characteristics of the electromagnetic fields were determined by the EMF induced in the measuring coil placed in the working area. The polarization properties of the Samotlor oilfield were investigated. The densities and viscosities of the samples were measured as a function of temperature and electrostatic and electromagnetic influences. It is shown that the decrease in density and viscosity increases when electrostatic and electromagnetic fields are applied. An increase in the mobility of molecules leads to a weakening of intermolecular forces and a decrease in the viscosity of the reservoir’s oil-containing liquid fluids. This is due to the fact that oil molecules — dipoles — perform forced synchronous oscillations under the influence of an external alternating field. At the same time, alternating conduction currents flow in liquid fluids, which leads to the release of Joule heat in the collector. It has been revealed that the effect of thermal and electromagnetic fields on oil reduces viscosity by 1.5 – 2 times. The results obtained can be used to improve methods for reducing oil viscosity to increase oil production.
