Types of Crude Oil and Their Importance

The oil industry frequently characterizes crude oils in relation to their geographical starting place. The main reason for this is that oils from particular geographical regions have distinctive properties, and they can be different in consistency from a semi solid to a light volatile fluid. The classification for crude oil types includes four classes which are Class A: light and volatile oils, Class B: non-sticky oils, Class C: heavy oils and finally Class D: non fluid oils. Usually, knowing the characteristics of each class is very important to offer an urgent response to oil spills wherever and whenever they take place, but also, this kind of information can help you make right decisions regarding investments.

Light and volatile oils are highly fluid and spread quickly on water and solid surfaces. They penetrate porous surfaces such as sand and dirt and may be extremely toxic to animals, plants and humans. The majority of refined products and many of the top quality light crudes belong to this class. On the other hand, non sticky oils are less toxic and remain more firmly in surfaces. Heavy and medium paraffin based oils are in this class.

Equal of known that light crude, heavy oils are normally, sticky, viscous and black or brown. Due to its density, this oil frequently sinks. Although it is not so toxic, it is possible that it contaminates flora and fauna. Medium to heavy crudes and residual fuel oils are included in this category. Finally, heavy crude, residual, some weathered and some paraffin oils are included in non fluids oils. These are comparatively non toxic and cannot penetrate absorbent substrates.
