Description

Crude oil is a consisting of a mixture of hydrocarbons of natural origin,yellow to black colour of variable specific gravity and viscocity.
Crude oil type has a unique composition and is a complex misture containing many thousands of hydrocarbon molecules of different shapes and sizes.                                                                           Crude oil varies radically inits properties,namely specific gravity and viscocity depending on the chemical nature of its chief constituents,crude oil isclassified as paraffin base,asphaltic base,or mixed base.         Crude oil is the mixture of petroleum liquids and gases(including Impurities such as "Sulphur" that is pumped out of the ground by oil wells.
