The effect of ultrasound and heat treatment on the dynamic viscosity, pour point, density, acidity, interphase tension at the water interface, and chemical composition of Ust-Tegusskoe oil is investigated. It was revealed that the plastic viscosity of the treated oil was diminished by a factor of 1.7 and the pour point by 32°C after ultrasonic treatment. Maximum depression of the pour point is obtained after ultrasonic treatment at 80°C and pressure of 1 atm in a helium medium.
