Many countries have oil reserves, these countries also have large oil wells. In such a situation, countries which do not have oil wells or reserves, have to buy oil from other countries or those countries also supply oil by extracting oil from the middle of the sea. In such a situation, the question arises that how will oil be extracted from the middle of the sea? And will it be safe with water around? Let us know today.
How is oil extracted from the sea?
Let us tell you that the process of extracting oil from the sea takes place in several stages. First, geologists and geophysicists must locate oil reserves under the sea. For this they use various techniques, such as seismic survey, gravity survey and magnetic survey.
Then once the oil reserves are located, a hole is drilled into the seabed using a giant drilling rig. When drilling is complete, oil is brought to the surface from the reservoir. That is why pumps are used. Meanwhile, along with oil, gas is also extracted. The extracted oil is then transported to refineries through pipelines or tankers.
Advantages and disadvantages of extracting oil from the sea
If we look at the benefits of extracting oil from the sea, this oil becomes a major source of energy around the world. Also, the oil industry contributes significantly to the economy of many countries. Along with this, it also provides employment to lakhs of people.
If we look at its disadvantages, oil leakage during the oil extraction process causes a lot of damage to marine life and coastal areas. Also, burning oil releases carbon dioxide gas, which is a major cause of climate change. There is a struggle going on between many countries for control of oil reserves.
