WebVI is calculated from viscosity measurements at 40°C and 100°C. The viscosities of paraffinic and naphthenic base oils have very different behavior with temperature change. Normally, paraffinic base oils have less viscosity variation (higher VI) than naphthenic base oil which display larger variation with temperature (lower VI). WebOct 6, 2024 · At present, it is widely used to reduce the viscosity of heavy oil in oil fields. (5,6) The cavitation, heating, and mechanical oscillation of ultrasonic treatment reduce the molecular weight of macromolecules by splitting the most susceptible chemical bonds, thereby decreasing the viscosity of oil. (7−9) Some researchers have carried out …
