Heavy oil and natural bitumen resources in geological basins of the world
Richard F. Meyer, Emil D. Attanasi, Philip A. Freeman
2007, Open-File Report 2007-1084
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...
