Oil field Reduced
Rumaila is currently reduced (since March 17, 2026): Southern Iraqi output was slashed in March (Basra Oil Co. ~3.3 to ~0.9 mb/d; force majeure 20 Mar). Iraq said exports reached ~2 mb/d in August, the highest since the war began, mostly via Hormuz and partly via Ceyhan.

Iraq. Supergiant field. ~1.5M bpd. Operated by BP/PetroChina JV. ~17 billion barrels remaining. Iraq's single largest producing field.
Iraq's post-2003 oil development has been dominated by Technical Service Contracts (TSCs) that give international oil companies fees rather than equity — a model designed to preserve Iraqi sovereignty over resources. The BP/PetroChina JV operating Rumaila is a notable example of UK-Chinese commercial cooperation in a US-liberated territory. Rumaila sits near the Kuwait border in the same geological formation as Burgan, and border disputes over the field were part of Iraq's 1990 justification for invading Kuwait.
Iraq's oil ministry declared force majeure on 20 March on fields operated by foreign companies after ordering shutdowns on 17 March; Basra Oil Company cut output from ~3.3 mb/d to ~0.9 mb/d with southern exports halted by the Hormuz closure. Rumaila had already cut up to 700 kb/d.
