Abstract The article summarizes experimental data on the influence of acoustic treatment and the nature of solvents on the viscosity of oil from the Timan-Pechora and the Volga-Ural oil and gas-bearing basin. A combined treatment of oils, including acoustic exposure to 22 kHz and the addition of a chemical reagent was carried out. It is shown that the introduction of 1.75% wt alkaline solution of isobutyl alcohol leads to a decrease in oil viscosity of the Timan-Pechora oil and gas-bearing basin by 35%. After complex treatment (acoustic exposure for 1 min and the addition of reagent) the viscosity decreased by 60%. The introduction of alkaline chemicals into the oil of the Volga-Ural oil and gas-bearing basin does not lead to a decrease in viscosity. Oil viscosity decreases by 2.1 times after the introduction of 3% wt solvent P-12 (60% toluene, 10% xylene, 30% butyl acetate). Viscosity reduces by further 18% after acoustic exposure. Thus, the maximum viscosity reduction of heavy oils can be achieved by using the combined treatment including of acoustic exposure and addition of the selected chemical reagent.
