Crude Oil Crude oil is formed through a long process which took place millions of years ago. Huge numbers of microscopic animals and plants died and fell to the bottom of the sea, which is then covered by mud sediments. These mud sediments got buried by more of them, and then started to change into rock, which created pressure and increased temperature. This resulted in the deceased plants and animals to heat up and slowly turned into fossils which then turns into crude oil. Since oil is less dense that the water in the rocks, the oil particles rose to form a layer of crude oil if rock layer was permeable. At some point, the oil reaches a layer of rock that’s impermeable, therefore gets trapped underneath that layer.

The first stage involves natural pressure driving the oil into the pipelines drilled into the ground in the oil wells. Later, the second stage consists of liquids being injected and pumping out remaining amounts of crude oil. Finally, the last stage involves using heat to force out the last of the crude oil that were previously difficult to extract. Crude oil is a compound in form of a liquid. Crude oil is composed mostly of hydrogen and carbon. Crude oil is also made up of mixtures of several other substances such as benzene, chromium, iron, mercury, nickel, nitrogen, oxygen, sulphur, toluene, and xylene. This mixture results in a dark, yellow, greasy liquid. Within crude oil, there are many different types of fuel that are used for different objects, depending on the number of carbon bonds. Some of these fuels are
