Oil Sands Geology and the Properties of Bitumen | Oil ...

BITUMEN EXPLAINED. Bitumen is a highly viscous, complex hydrocarbon, classified as an extra heavy oil.Pure bitumen has an API gravity of about 8°, and is almost solid at room temperatures. Alberta bitumen also contains about 4 to 5% sulphur, with trace concentrations of heavy metals, particularly nickel and vanadium.

Heavy oil and natural bitumen resources in geological ...

Heavy oil and natural bitumen are oils set apart by their high viscosity (resistance to flow) and high density (low API gravity). These attributes reflect the invariable presence of up to 50 weight percent asphaltenes, very high molecular weight hydrocarbon molecules incorporating many heteroatoms in their lattices. Almost all heavy oil and natural bitumen are alteration products …

How is bitumen cracked in an oil refinery? - Answers

Bitumen and any other heavy oils can be cracked either thermally, catalytically or by the addition of hydrogen at high pressures. Typical …

Tar sand (also known as oil sand and bituminous sand) is a sand deposit that is impregnated with dense, viscous petroleum-like material called bitumen. Heavy oil reservoirs and tar sand deposits are widely distributed throughout the world in a variety of countries. Although the heavy oil reservoirs can be seen as reservoirs that are very similar in geological character to …

UPGRADING AND REFINING OF NATURAL BITUMEN AND HEAVY OIL

Tar sand (also known as oil sand and bituminous sand) is a sand deposit that is impregnated with dense, viscous petroleum-like material called bitumen. Tar sand deposits are widely distributed throughout the world and the various deposits have been described as belonging to two types: (a) stratigraphic traps; and (b) structural traps although gradations between the …

Phase Behavior and Properties of Heavy Oils | SpringerLink

Abstract. The phase behaviors and thermophysical and transport properties of heavy oils not only share numerous features with light oils and reservoir fluids, but also exhibit substantial differences because of their more complex chemistry …

Natural bitumen and extra-heavy oil | U.S. Geological Survey

Since 2005, oil price increases have greatly increased investment in the production of extra- heavy oil and natural bitumen (tar sands or oil sands) to supplement conventional oil supplies. These oils are characterised by their high viscosity, high density (low API gravity), and high concentrations of nitrogen, oxygen, sulphur, and heavy metals.

chemistry and physics of natural bitumen and heavy oil

Natural bitumen and extra-heavy oil differ in the degree by which they have been degraded from the original conventional oils by bacteria. Thirty or more countries are known to have reserves. Production, transportation, and refining of heavy crude oil present special challenges compared to light crude oil.

Natural Bitumen and Extra-Heavy Oil

Chemistry Extra-heavy oil and natural bitumen rep-resent crude oils which have been severely degraded by microbial action, as evidenced by their paucity of low-molecular-weight saturated hydrocarbons.
