We have been learning about rocks and the structure of the earth in Primary 6 and we have been learning about fossil fuels. On Monday 4 December, Miss Aslam talked to us about oil and gas: how they are made and how we use them. You might be surprised at the number of things that oil is used for. We use oil to fuel our city. We use it for running planes, cars motorbikes and many more things. We all used oil this morning because of our toothpaste! Some shoes have oil products in them, and it is also put in medicines, make-up and plastics. Gas is also very useful. It keeps our homes warm and cosy. Oil and gas both come from the ground. So how do we get to these useful products we need? Miss Aslam is a geoscientist. Geoscientists figure out where to find oil and gas and then the engineers actually drill down and bring it up. They use wells that are supported by rigs. Wells drill down into the sea bed or onto the land. If the well is on the sea bed, engineers have to live on the rigs. It can cost millions of pounds just to get down to the oil field, so geoscientists have to be sure there is enough oil or gas in the field. If the oil company does not take the advice of the geoscientists, they can lose a lot of money.
One day, we might run out of oil. Oil is formed by dead creatures that fall to the sea bed, and it takes millions of years to form. It is then stored in sedimentary rocks. The most oil and gas comes from the United Arab Emirates, in the Middle East. They are lucky because it is in their back yard, so it is easy to find. Miss Aslam told us that, when she was working on a particular oil rig, they drilled 15 to 20 m per day, it took them 67 days to drill and it was working for 3 years. If you become a geoscientist, like Miss Aslam, you can travel the world and meet all sorts of interesting people.
