List of oil fields
This list of oil fields includes some major oil fields of the past and present.
The list is incomplete; there are more than 25,000 oil and gas fields of all sizes in the world. However, 94% of known oil is concentrated in fewer than 1,500 giant and major fields. Most of the world's largest oilfields are located in the Middle East, but there are also super giant oilfields in Brazil, Mexico, Venezuela, Kazakhstan, and Russia.
A field containing 500 million barrels or more ultimately recoverable reserves is a giant field, while a super giant contains 5 billion barrels or more recoverable reserves.
Amounts listed below, in billions of barrels, are the estimated ultimate recoverable petroleum resources, given historical production and current extraction technology. Oil shale reserves and coal reserves, both of which can be converted to liquid petroleum, are not included in this chart. Other non-conventional liquid fuel sources are similarly excluded from this list.
Scientific assessments indicate the existence of substantial undiscovered, technically recoverable oil and natural gas resources in Arctic and other regions, but commercial exploration has either failed or not commenced due to unavailability of permits and approvals, restrictive policies, environmental risks and logistical challenges. The list excludes fields where commercial development has been unsuccessful and fields with no current plan for development and extraction.
Current production is for 2025, except when the year is specifically provided along with the production figure.
