Oil is extracted from the earth through oil wells which are drilled deep into the earth and then a pump is used to bring the oil to the surface.
The oil then gets sent to refineries where it is then processed into gasoline and other fuels such as propane, motor oil, Diesel Fuel etc.
Oil does actually replenish itself because oil is actually made from plants.
However the oil takes several years to replenish itself once it's depleted.
Oil also known as crude oil is a type of fossil fuel that is not only from plants but also from dead animals.
A fossil fuel is a hydrocarbon-containing material formed underground from the remains of dead plants and animals that humans extract and burn to release energy for use.
The main fossil fuels are coal, petroleum and natural gas, which humans extract through mining and drilling.
So contrary to popular belief oil is a renewable resource but it takes several years for the oil to renew once it's gone.
However we are likely not ever gonna run out of oil or other fossil fuels for a very long time and even then the fossil fuels will likely replenish eventually.
Fossil fuels include coal, petroleum, natural gas, oil shales, bitumens, tar sands, and heavy oils.
Crude oil means a mixture of hydrocarbons that exists in liquid phase in natural underground reservoirs and remains liquid at atmospheric pressure after passing through surface separating facilities.
Liquids produced at natural gas processing plants are excluded.
Petroleum, also known as crude oil and oil, is a naturally occurring, yellowish-black liquid found in geological formations beneath the Earth's surface.
It is commonly refined into various types of fuels.
Crude oil exists in liquid form in underground reservoirs in the tiny spaces within sedimentary rocks.
Or it can be found near the surface in oil sands.
It is often found alongside natural gas and saline water.
Crude oil is often interchangeably referred to as petroleum.
Also scientists have actually discovered a new way to make crude oil from plants without the need to drill for oil so we may never really run out of crude oil.
A new discovery could let scientists artificially create crude oil in under an hour, accelerating a natural process that normally takes at least a few million years to complete.
