Scientists have come to find that millions of years ago in a marine environment before the dinosaurs, the remains of animals and plants would greatly impact our society today. By these remains and their aging process we now have oil, which we now in the twenty-first century use on a daily bases. We need oil in this day and age, so where does it come from? How do we get it?
Oil is located underneath the ground; it is the reaction of millions of years of decomposing underneath the trap of sediments beyond the water of the ocean floor. The silt and sand over time hardens to rock and more rock collects on top of that. Heat and pressure from the covering of the remains result into what we call crude oil, this also creates kerogen which is a mixture of organic chemical compounds which make up organic matter in sedimentary rocks, which happen to be permeable, and the ratio of pores in that sedimentary rock are called porosity. Hydrocarbons also are found naturally in crude oil, because decomposed matter provides a variety of carbon and hydrogen. Oil sometimes referred to as “petroleum” and the root meaning is “oil from the earth”; with this said, one can conclude that oil is purely organic.
After the aging process is complete, the oil is taken from the ground for human needs and wants. The process of extracting the oil from the ground consist of drilling deep down into the earth. This ending has two conclusions; first, when the drill hits the oil, which has been under pressure for many years, the oil will gush out, or another conclusion, the more common one, that the drill hits the oil and the oil pumped to the surface. Then the oil is ready to go taken to the reservoir rock, which is a place where oil migrates and is contained underground. After that process, it is ready to sell for human uses such as burning oil in your cars engine.
