where is most oil found in the world
List of oil fields The list is incomplete; there are more than 65,000 oil and gas fields of all sizes in the world.[1] However, 94% of known oil is concentrated in fewer than 1500 giant and major fields.[2] Most of the world's largest oilfields are located in the Middle East, but there are also supergiant (>10 billion bbls) oilfields in Brazil, Mexico, Venezuela, Kazakhstan, and Russia.
