The world’s oil supply begins in fields scattered across continents – from the Saudi Arabian desert to the North Sea and the Permian Basin in the United States. Once extracted, crude is either loaded onto tanker ships at coastal ports or pumped through pipelines to inland hubs. These hubs connect to a network of maritime routes that cross oceans, strategic chokepoints such as the Strait of Hormuz, and land corridors that deliver oil to refineries in Europe, Asia and the Americas.
After refining, the finished products travel again – this time through distribution pipelines, rail cars, trucks or smaller tankers – to reach storage facilities and retail stations. Every link in the chain depends on contracts, regulations and market forces, making the global oil trade a complex but fascinating system that powers modern life.
