“…The type composition of crude oil is known to vary depending on several characteristics including type of geological formation, location, age of the oil field and depth. These factors can cause the metal concentration to change appreciably [4,5]. The quantities of individual metals differ significantly in different crude oils and asphalts and even in the same type of crude oil field from different localities [6].…”

“…Large reserves of high-viscosity oils are found in Canada, Venezuela, Mexico, the USA, Russia, Kuwait and China [2]. Average heavy oil production is now about 12% of total world oil production [3]. Different categories of heavy crude are usually defined according to their density and viscosity, as illustrated in Figure 2.…”
