Oil Transportation and Major Chokepoints
The bulk of the oil transported (62%) is using maritime transportation, which follows very specific routes and which is constrained by strategic passages that are commonly referred as chokepoints. The Persian Gulf is a major source of oil shipped by maritime transportation with maritime routes reaching Europe through the Suez Canal, China, Japan and South Korea, through the Strait of Malacca and North America through the Cape of Good Hope. Russian oil exports are going through the strait of Oresund, mostly towards European markets. Limited oil trade takes place across the Pacific since there are few significant producers. Most Mexican oil exports is bound to the United States while Indonesia has ceased to be a significant oil exporter.
Major continental movements involve the Russian and former Soviet Republic's petroleum shipped to Europe by pipeline and Alaskan and Canadian petroleum shipped to the United States also by pipeline. Other important oil shipments are from Africa to North America and Europe, from the North Sea to Europe and from South America to North America.
