Crude oil production capacity

mb/d · irregular

The volume of crude oil a country can produce, million barrels per day, as stated by its national oil company or by the IEA. Current capacity, not a future target.

Methodology: Definitions differ by source and are stated in each figure's note: Aramco's 'maximum sustainable capacity', ADNOC's 'capacity of oil per day', the IEA's 'sustainable capacity' (reachable within 90 days and sustained for an extended period). Not comparable across sources. Capacity is not production: output is set by OPEC+ quotas and, in 2026, by Gulf shipping disruption.
