Question

Without oil the modern world could not exist. Oil is needed for travelling, because it powers our motor cars, buses, trains, aeroplanes and ships. Oil helps all kinds of machines, to run easily. Oil also gives us other substances, such as artificial rubber, artificial material for clothing, and new material for making things. But hundred years ago no one was using oil for any of these purposes. In fact, no one knew that much oil existed. Men did not make oil; they found it. They looked for oil in many ways. They began by making a map of the land where they were searching. Then they used the map in choosing a site carefully to explore more. Theystarted their work by examining the rocks under the surface and came to know whether oil was likely to be underneath the rock. To find out how deeply the oil was buried first they needed to know how far under the surface the rock was. If everything seemed hopeful the men decided to drill down through the rock. In this way they found out whether oil really existed underneath it. Often this test – well, as it is called, is far away from any town and there was much work to do before any drilling started. Houses and roads must be built for the people coming to drill the test – well. Then the big derrick that carried the drill must be put up. This derrick was a strong framework of steel about 45 meters high. The drill was raised and lowered inside the derrick. Drilling for oil often means making a well that goes very deep into the earth. Such deep wells have never been made until modern times. The rate of drilling depends upon the kind of rock being drilled: it can be as fast as 60 meters an hour. Drilling is usually done on dry land, but started their work by examining the rocks under the surface and came to know whether oil was likely to be underneath the rock.

Drilling is usually done on dry land, but we can also drill the rock under lakes or seas by putting the derrick on a special platform above the water.
