Oil Trade Routes

The global trade of oil is big business. Each year, BP carries out a Statistical Review of Energy and the image below shows the global trade of petroleum in 2010 in millions of tonnes.

To help visualise this a little clearer I found this diagram which uses the data produced by the BP review to draws arrows, where the thickness represents the level of trade. Oil barrel symbols are imports, Pumpjacks (nodding donkeys) are oil exports.
