Answer :
Oil extraction methods include primary and secondary extraction, strip mining, and subsurface mining, with each technique chosen based on the oil deposit's characteristics and economic considerations.The Correct Answer is All the above.
The process of extracting oil involves several techniques. The initial phase, called primary extraction, involves drilling wells to access oil that flows naturally due to underground pressure. In secondary extraction, water or gas is injected to maintain pressure and extract additional oil beyond what primary recovery can achieve.
When it comes to mining for oil, strip mining is a method used for extracting tar sands or oil shale from near the earth's surface. This involves removing layers of earth to access the resource. On the other hand, subsurface mining involves creating tunnels or shafts underground to reach the deposits of oil shale or tar sands, where direct burning or processing to extract oil can occur.
Fracking, another method, entails the injection of high-pressure fluids underground to fracture rocks and release trapped fossil fuels. Although fracking is not a direct method of primary or secondary extraction, it is a form of enhanced oil recovery (tertiary recovery).
Each of these methods has various environmental impacts and is chosen based on the type of oil deposit, the depth at which it is located, and other economic factors.
