List of oil fields

The list is incomplete; there are more than 25,000 oil and gas fields of all sizes in the world.

[1] However, 94% of known oil is concentrated in fewer than 1,500 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.

Amounts listed below, in billions of barrels, are the estimated ultimate recoverable petroleum resources (proved reserves plus cumulative production), given historical production and current extraction technology.

Other non-conventional liquid fuel sources are similarly excluded from this list.
