The exploitation and transportation of heavy oil has been a challenging task due to its high viscosity and poor fluidity. To address these issues, it is necessary to study the properties and viscosity reduction methods of heavy oil. In this chapter, the composition and source of viscosity of heavy oil are introduced. To reduce the viscosity of heavy oil, five methods are put forward such as thermal method, dilution, emulsification, oxidation, and hydrothermal catalytic pyrolysis. Viscosity reduction mechanism of various methods is also discussed.
