Definition - What does In Situ mean?
In Situ is a recovery technology that is used to extract oil present deep beneath the earth’s surface. Heat or solvents are injected into heavy oil reservoirs buried deep below the earth’s crust so as to separate them from sand and bring them to the surface. This technique is considered to be better than the normal mining technique as it is less harmful to the environment and it uses limited land and water source.
Petropedia explains In Situ
The extraction of oil utilizes two techniques, Mining and In Situ. In the mining technique, the extraction harms the environment because trees and bushes are removed from a large area of land assumed to have oil. This technique is costly and time consuming as well. On the other hand, In Situ technique utilizes only a limited area of around 100 meters. Steam or other sources of heat are infused deep below the surface and oil is separated from the sand. The extracted products are taken to refineries where they are upgraded, processed and tuned into useful oil products. This is the future technique of extracting oil from sand as it is predicted that huge amounts of oil are present in the oil sand too deep beneath the earth’s surface.
