The sound of oil tread

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.
