Crude oil straight out of the ground is not uniform (clean), but is composed of many fractions which can be extracted simply by weight.
Other fractions can be 'cracked' by heat, pressure, solvents and distillation.
To distinguish from other, purer oils, the basic material is called 'crude'.
Strictly speaking, 'petroleum' itself is a fraction of crude.
Crude Oil is hydrocarbon and it is mixture of carbon and hydrogen.
That's "petroleum"!
Petroleum is refined from crude oil and is but one fraction only
