When crude (oil) is extrated from the deep inside the earth, what replaces it if? If anything!!!?

Answer 1

Nothing, as Petroleum is a non-renewable resource. It is found in the upper layers of the earth's crust, not deep inside the earth and formed by the heat and compression of decayed remains of prehistoric small marine animals over long periods of geologic time.

Answer 2

Crude oil is (most often) pumped from the ground: the replacement product being pumped down is a mixture of air and water. In a "gusher" the oil is pumped out of the earth by pressure on it below the earth -- so rock is effectively replacing the volume of the oil that gushes.
In the other sense of "what replaces it", oil is effectively a non-replaceable substance, typically formed over enormous times by rock pressure on decayed organic matter, such as destroyed forests and schools of fish. Once oil is consumed as fuel, there is less oil in existence. Thoery is that oil is being formed constantly, but in small amounts over extremely long periods of time, but hardly enough to say that oil is being "replaced".

Answer 3

In a petroleum reservoir (a porous rock, think of it being like a sponge) there is normally some natural gas present as well as the oil and water. The gas is often at the top, then oil and water at the bottom.

When you drill into the reservoir, the oil will at first flow without you having to pump it because it is under pressure, and the volume of the extracted oil will be replaced by expansion of gas, by compression of the reservoir rock (think of it being squeezed like a sponge by the millions of tons of overlying rock), and to some extent by water flowing in to replace the extracted oil.

Later the oil pressure drops and pumping has to be used to produce more oil. Either gas, (methane or CO2) can be pumped down another well in the same reservoir to increase the pressure, or alternatively water can be pumped down another well for the same purpose (this is called a water flood).

So, the answer is gas or water, replaces the volume to some extent but compression does also occur and there is the potential for oil extraction to cause some subsidence of the land/ sea-bed.

Answer 4

The earth and that includes under the sea bed is not solid. It is made up of atoms and molecules so they just realign. Its like when you dust the side boards at home you just move the dust to another place. Quantum Physics is fascinating if you want to know more google Quantum Physics.

Answer 5

Sea Water, the drill head is at the top of the well, the water which is heavier sinks to the bottom

Answer 6

Actually depending on where they drill they normally try to fill it back in with coal ect.. or if they are out to sea, water , but eventually they wont be able to fill in the holes cause of how deep they are drilling. but the earth has it's ways of letting us know if we go to deep ( valcanos) emerg from fishers and we are creating a few lately so i hope that helps on your search.

Answer 7

Proably water, most is below sea level after all.

Answer 8

sea water, If it's out to sea, I think...

Answer 9

Oh my god! Now I'm scared! Are we gonna implode???????
