European Oil Markets: GL 131F resets the Lukoil sale clock- Who owns the ISAB refinery in Sicily?
- ISAB is held by Lukoil International GmbH, a Swiss entity that consolidates Lukoil's non-Russian European refining assets. The refinery has been under Italian government oversight since 2022 and is now subject to an OFAC-supervised sale process.Source: event_lookup
- What happens to ISAB if the OFAC deadline is not met?
- General Licence 131F authorises sale negotiations through 27 June 2026. If no buyer is found and no further extension granted, the sanctions perimeter tightens around the refinery, making any transaction without a specific OFAC licence unlawful and potentially halting commercial operations.Source: event_lookup
- How big is the ISAB refinery in Sicily?
- ISAB has throughput capacity of roughly 800,000 Barrels Per Day, making it one of the largest refineries on the Mediterranean and a significant swing supplier for southern European diesel and jet fuel markets.Source: event_lookup
- Why has the Lukoil ISAB sale not closed after six OFAC extensions?
- OFAC's FAQ 1224 conditions require a buyer to completely sever the holding from Lukoil, park any funds owed in a US-jurisdiction blocked account, and provide no upfront value to Lukoil. That structure forces a buyer to front capital with no recourse, which has deterred credible bidders through six successive licence rollovers.Source: event_lookup

Background
The ISAB (Industria Siciliana Acido Borico) complex at Priolo Gargallo, near Syracuse in south-east Sicily, is one of the largest and most strategically important oil refineries on the Mediterranean. With throughput capacity of approximately 800,000 Barrels Per Day, it processes predominantly sour and medium-grade crude from North Africa and the Middle East into petrol, diesel, jet fuel, fuel oil, and petrochemical feedstocks. Its coastal location on the Augusta Bay gives it direct access to Med shipping lanes, making it a swing refiner for the entire southern European products market.
The refinery was built in the 1970s by Italian petrochemical interests and passed through several ownership phases before Lukoil acquired a controlling stake in the mid-2000s, consolidating it inside its Lukoil International GmbH Swiss holding vehicle alongside Neftochim Burgas in Bulgaria and Petrotel Ploiesti in Romania. Following Russia's February 2022 invasion of Ukraine, the Italian government and the EU began scrutinising the refinery's Russian ownership. From late 2022 onwards the site operated under a temporary administration arrangement managed by Italian authorities, with G.O.I. and later associated parties involved in oversight discussions. Full details of the interim ownership arrangements are subject to ongoing legal and regulatory processes.
ISAB is now at the centre of a US sanctions deadline. OFAC General Licence 131F, issued on 28 May 2026, is the sixth iteration of the Lukoil sale-licence series and authorises negotiation and contingent contracts for the transfer of Lukoil International GmbH and its European refining assets through 27 June 2026. Any actual transfer requires a separate specific licence; the buyer must completely sever the holding from Lukoil, park funds owed in a US-jurisdiction blocked account, and provide no upfront value to Lukoil. That structure has deterred buyers through six successive licence extensions. If no sale closes by the deadline and no further extension is granted, the sanctions perimeter around ISAB tightens significantly, with immediate consequences for Med diesel and jet fuel availability.
