What are the two ways of oil extraction?
Conventional oil is extracted from underground reservoirs using traditional drilling and pumping methods. Conventional oil is a liquid at atmospheric temperature and pressure, so it can flow through a wellbore and a pipeline – unlike bitumen (oil sands oil) which is too thick to flow without being heated or diluted.
Where do we extract oil?
Today, petroleum is found in vast underground reservoirs where ancient seas were located. Petroleum reservoirs can be found beneath land or the ocean floor. Their crude oil is extracted with giant drilling machines. Crude oil is usually black or dark brown, but can also be yellowish, reddish, tan, or even greenish.
Does oil replenish itself?
If oil were naturally generated in the earth, it would follow that depleted oil reserves would refill themselves over time. Proponents of the abiogenic theory often claim that the supply of oil from the earth is effectively limitless.

- India4.8%
- Japan3.8%
- Russia3.6%
Can we drink crude oil?
For most people brief contact with a small amount of oil will do no harm. Some people are more sensitive to chemicals, including those found in crude oil. Swallowing small amounts (less than a coffee cup) of oil will cause upset stomach, vomiting, and diarrhea, but is unlikely to have long-lasting health effects.
Is crude oil used to make plastic?
Although crude oil is a source of raw material (feedstock) for making plastics, it is not the major source of feedstock for plastics production in the United States. Plastics are produced from natural gas, feedstocks derived from natural gas processing, and feedstocks derived from crude oil refining.
How is plastic made step by step?
Plastics are made from raw materials like natural gas, oil or plants, which are refined into ethane and propane. Ethane and propane are then treated with heat in a process called “cracking” which turns them into ethylene and propylene. These materials are combined together to create different polymers.
Can you make plastic without fossil fuels?
Scientists have discovered a previously unknown way that some bacteria produce the chemical ethylene – a finding that could lead to new ways to produce plastics without using fossil fuels. The study, published today (Aug. Ethylene is widely used in the chemical industry to make nearly all plastics, North said.
Can plastics be made without oil?
A process is under development for making polyesters which is independent of crude oil, since it uses ethylene as its feedstock. Ethylene, conveniently, can be made out of natural gas liquids, or even shale gas itself.
