I THINK petroleum
You're thinking on the right track, but in reverse. Petroleum is a product made from crude oil, not the other way around. Crude oil is made from extinct biomass, that is plants and animals that lived millions of years ago, subjected to underground pressure over a long period of time until the oil is all that is left of them.
Oil is commonly formed in rock or in sealed pockets under the seabed and it is from the Latin for 'rock oil' that the word 'Petroleum' is derived

The crude oil we use today was formed millions of years ago but crude oil is still being formed today. More crude oil is formed every time an animal or plant in the sea dies and is squashed by layers of other dead marine life (that turns into rock)over the top. This takes a long time.
