Oil has become one of the most important fuels in the world. Diesel oil, petrol and aircraft fuel are all made from the thick, black liquid that is brought up from under the ground or he sea-bed. Oil is also used as lubrication to make machines run smoothly. And without oil there would be no plastic. Oil began to be formed millions of years ago when plants and animals died and fell into swamps where they mixed with mud and sand. With the passing of time and movements of the Earth’s crust, the layers of mud and sand became rock. Under the immense pressure of the rock, the oil was formed and collected in large lakes deep underground. It is surprising that today much of the world’s oil comes from dry desert regions where there is little vegetation. Scientists are always searching for new locations to drill for oil. Probably the majority of the oil under the land has been found and now more oil wells are being drilled under the sea-bed. No-one really knows how much oil remains to be discovered, but we do know that one day it will run out.
Do you think it is difficult to bring oil to the surface? why do you think that?
Why do you think it is difficult to know how much oil is left in the world?

I think it would be very hard to drill to find oil because you have to do it underwater or the the earth's crust. It is impossible to know how much oil it left because not every place in the world has been checked and the cant tell how much they have all ready tapped into
I think that it is very hard to get oil, Due to the fact they don't know where it is, and they have to dig extremely deep into the earths crust. Eventually if they keep digging in the sea bed the oil may pollute the water. There is no way we can tell if we are running out of oil so if we stop using it now we can just go to eclectic cars and stop paying the outrages petrol bills
I think bringing oil up from under the ground as it is under the earths crust, so it must be very deep. It would be even harder to bring it up from under the ocean as you would have to go through the sea first.
It would be hard to tell how much oil is left in the world as it states that scientists are constantly looking for new spots with oil in them,meaning there is most likely more to be found and you cannot be sure how much oil they have in them.

I think it is difficult to bring oil up to the surface because you would have to dig deep down under the sea bed and once you have done that you would have to get a a special machine and then bring it up using the machine to the surface.
I think it is difficult to know how much oil is left in the world because we don't no exactly were it is and how much is in one spot.
No i dont think it would be to hard to suck out the oil because all you really need to do is have a strong enough drill to get through the rock and then suck it out.
Probably because they dont know how thick the rock is and how far the oil stretches for so they cant calculate how much oil there is exactly

I think it is difficult to bring oil to the surface via sea-based oil rigs. Long drills and tubes would have to extended to the seabed. if there was no oil in the location then the organisation that built the oil rig will have an empty husk out in the sea. Large amounts of drilling would be required to bring oil to the surface.

It is difficult to know how much oil is left in the world without knowing how much was made in the first place. As we do not know how many animals and plants have undertaken the transformation into oil. Without this knowledge and an exact amount of oil removed from the ground it is impossible for us to know how much oil is left on Earth.
yes I think that oil would be difficult to bring to the surface. I think this because oil is found very deep down and would take a long time to bring up, and it is very thick and dense.
I think that it is difficult to know how much oil is left in the world because it's hard to find different drilling places and it's not unlimited.
Yes I think it is difficult to bring the oil to the surface because you have to drill all the way under the seabed which is really deep.
I think it is difficult to know how much oil remains because in the text it says not all of it has been discovered yet.
