recoverable and in-place oil or bitumen by accumulation. Where
unavailable, recovery factors of 10 percent and 5 percent of heavy oil
or bitumen in place were assumed for sandstone and carbonate
**In addition, 212.4 billion barrels of natural bitumen in place is located in
Russia but is either in small deposits or in remote areas in eastern Siberia.
In spite of an immense resource base, heavy oil and natural bitumen accounted for only about 3 billion barrels of the 25 billion barrels of crude oil produced in 2000. Compared to light oil, these resources are generally more costly to produce and transport. Also, extra-heavy oil and natural bitumen must usually be upgraded by reducing their carbon content or adding hydrogen before they can be used as feedstock for a conventional refinery. The extra production, transportation, and upgrading costs explain why development and production of extra-heavy oil and bitumen are still limited. Their abundance, strategic geographic distribution, quality, and costs will shape their role in the future oil supply.
