Abu Dhabi National Oil Co. has restored its Ruwais refinery to full operating capacity after an Iranian drone attack caused a fire and halted the facility in March 2026. The complex can process more than 922,000 barrels of crude and condensate per day, making it the world’s fourth-largest single-site refinery, according to ADNOC. It produces diesel, jet fuel, gasoline, naphtha, LPG and other petroleum products, many of which are exported. Product exports have recovered to roughly 70% of pre-conflict levels, compared with about 600,000 barrels per day before the war, while ADNOC has increased diesel and jet-fuel shipments. The restart adds supply to global markets strained by Middle Eastern refinery outages, Ukrainian attacks on Russian refining infrastructure and disruptions to shipping through the Strait of Hormuz. Ruwais is particularly important to Europe because it traditionally sends significant diesel volumes to the region. Kuwait’s Mina Al Zour refinery is also increasing output. The recovery comes as diesel refining margins reach their highest levels in more than 15 years. The latest Ruwais update represents a faster return to full operating capacity than the earlier expectation that the refinery’s recovery would form part of a broader regional normalization targeted for the second quarter of 2027. Elsewhere in the UAE, Habshan had restored 85% of gas supply by early August 2026, above ADNOC Gas’s 80% year-end target, while Emirates Global Aluminium’s Al Taweelah alumina refinery had reached roughly 50% of output capacity by late August. Regional refinery throughput remained about 7.3 million barrels per day, down from 9.9 million before the conflict, and Brent crude was approximately 40% higher than before hostilities began on February 28, 2026.
