The following table shows the ten largest national oil companies ranked by reserves [29] [30] and by production in 2012. [31]
Due to the great surge in American production of oil, natural gas, and natural gas liquids since 2008, those products have been cheaper in the North American market than worldwide, giving American refiners a major cost advantage. [19] The discount on US crude is partially attributed to the long-standing federal ban on exports of American crude oil.

An oil refinery or petroleum refinery is an industrial process plant where petroleum (crude oil) is transformed and refined into products such as gasoline (petrol), diesel fuel, asphalt base, fuel oils, heating oil, kerosene, liquefied petroleum gas and petroleum naphtha.
A Stanford University study commissioned by the EU in 2011 found that oil sands crude was as much as 22% more carbon-intensive than other fuels.
