The world’s largest oil fields are located in the Middle East, with the Ghawar Field in Saudi Arabia claiming the title for the world’s biggest oil field, producing 5 billion barrels of oil a day. It is around 3,306 sq. miles big – that’s larger than the size of Greater London! And an oil fact that’s even harder to believe is that the entire oil field accounts for around a third of the oil production in Saudi Arabia.
