Our Heavy Crude Oil

Oil resources similar to WTI and Brent crude oils are dwindling, so heavy and extra-heavy crude oils, and must be used to meet the growing demand for fuels. The vast majority of the world’s refineries are not suitable for processing these types of feed stock, so upgrading processes are required to make synthetic crude oils from those resources compatible with the equipment installed. By its viscosity Castilla crude oil is not classified as an extra-heavy crude oil, as even on surface it flows. However, it has 45.6 wt.% of vacuum bottoms and high concentrations of Conradson Carbon (CCR of 34 wt.%) and metals (nickel and vanadium content of 928 ppm) within it

Light vs Heavy Crude Oil

Light Crude oil is liquid petroleum that has low density and that flows freely at room temperature. It has low viscosity, low specific gravity and high API gravity due to the presence of a high proportion of light hydrocarbon fractions. It generally has a low wax content as well. On the other hand, heavy crude oil or extra heavy crude oil is any type of crude oil which does not flow easily. It is referred to as “heavy” because its density or specific gravity is higher than that of light crude oil. Heavy crude oil has been defined as any liquid petroleum with an API gravity less than 20°
