Crude oil is a thick, dark, naturally occurring liquid made mostly of hydrocarbons. It forms over millions of years as heat and pressure transform buried marine organisms into oil trapped in porous rock.
On its own, it isn't usable; refineries heat it and split it, through a process called fractional distillation, into fuels like petrol, diesel and jet fuel, plus lubricants, asphalt and plastic feedstock.
