What are the oil sands?

Oil sands refer to unconventional oil deposits. It is composed of shifting sand or partially consolidated sandstones. The sand comprises a mixture of clay, sand and water which is saturated with a form of oil called bitumen which is extremely viscous and dense. Therefore, the other terms referring to tar sands are tar sands, tar sands or raw bitumen. The countries that have vast reserves of raw bitumen are Canada, Venezuela, Kazakhstan and Russia.

The natural bitumen found in Canada is considered highly viscous and commercially difficult to recover. Oil sands have recently been included as part of oil reserves. Although oil sand is classified under the controversial non-burning coal, its extraction provided energy security.


Initially, the term “tar sands” was used during the last 19 and early 20th centuries to refer to tar sands. During this period, tar sands were widely used. As a result, a large tar residue was released due to its excessive use. The use of bitumen, however, goes even further when the first human beings used it in buildings and buildings. The use of bitumen for mummification and the construction of Egyptian pyramids was also recorded.

Production and extraction

Oil sands are considered the primary source of unconventional oil with Canada, leader in the production of this type of oil. Some of the companies specializing in oil extraction from tar sands are the Marathon Oil Corporation, Petro-Canada and the Syncrude Consortium, etc. Venezuela also has vast reserves of oil sand.
