How long does it take to make oil from nature?

Answer 1

Under ideal conditions small amounts of oil have been known to form in less than ten thousand years. Typical oil deposits, however, likely required hundreds of thousands to a few million years to form.

Many of the coal and oil deposits in the Eastern United States formed during the Carboniferous period around 350 million years ago. Most of the oil in the Middle East formed around 145 million years ago, between the end of the Jurassic and beginning of the Cretaceous.

Most of the oil and gas that formed since the Permian probably leaked out of overlaying permeable rock during intervening ages and was subsequently destroyed. We are fortunate large reserves remained trapped here and there where we could exploit them. Though we still have sufficient coal reserves to last us another few centuries, the age of oil is drawing to a close. We'll be able to continue extracting shale oil and other oil reserves for some decades yet to come, but it is unlikely we will be able to significantly ramp up production even if we wanted.

It is possible the evolution of cellulose digesting fungi have prevented the formation of significant oil reserves since the the beginning of the Cenozoic.

Answer 2

any carbon-based life form will make coal, diamonds, or oil if it dies and is buried just right. you need quite a lot to get a significant amount and the process takes millions of years. In all technicality oil is actually renewable... it just takes millions of years.

Answer 3

It takes about a month for crude oil to be refined into gasoline. Of a 42 gallon barrel of crude oil, only about 19.2 gallons of it is refined into gasoline.

Answer 4

Oil is considered an non renewable resource because it takes from hundreds of thousands to millions of years to form.

Answer 5

100 year because the dimecular substances dont turn colors in a day or two but they will eventually disapears.

Answer 6

it takes 1,896 million years to make oil

Answer 7

million of years
