It is called Crude Oil
Oil is pumped out of the ground
Oil is pumped out of the ground by first locating the oil and determining how far below the ground it is. A large drill is then used to drill to where the oil is and a rig is used to pump the oil out of the ground to be sent off to the refinery.
Oil is pumped from deep under the ground. It is a fossil fuel, made millions of years ago.
Oil being pumped out of the ground can not be replaced in our lifetimes.
No, nothing is put in the ground to replace crude oil.
It has to be pumped. A drill is used to drill down to the oil and then a pump is setup to get the oil out.
