The deposits of tar-like bitumen in central and northern
Alberta are among the world's largest petroleum resources. However, the viscous
substance is too thick to flow through rocks, wellbores and pipelines. Many
technological and economic challenges have to be overcome in order to produce
and transport bitumen and to process it into desirable products, such as gasoline
and diesel fuel.
