ISAB is held inside Lukoil International GmbH under GOI Energy administrative management. Ludoil Energy agreed on 18 May 2026 to buy the stake, but the acquisition requires both Italian Golden Power final clearance and a US OFAC transaction licence. Neither has been issued; GL 131G extends negotiations to 25 July 2026.Source: European Oil Markets briefing

What happens to ISAB if the OFAC deadline is not met?

If GL 131G lapses on 25 July 2026 without a successor licence or completed transaction, the sanctions perimeter tightens around the refinery, making any transaction without a specific OFAC licence unlawful and potentially halting commercial operations. OFAC has so FAR issued successive extensions rather than allowing a hard lapse.Source: OFAC General Licence series

How big is the ISAB refinery in Sicily?

Background

The ISAB (Industria Siciliana Asfalti e Bitumi) complex at Priolo Gargallo, near Syracuse in south-east Sicily, remained under OFAC's managed-divestiture framework as of 30 June 2026 after OFAC issued GL 131G on 25 June, the seventh consecutive monthly extension of the Lukoil-sale negotiation window. GL 131G succeeds GL 131F, which lapsed on 27 June 2026 without a transaction licence being issued, and extends authorised negotiations to 25 July 2026. The sale to Ludoil Energy remains stalled behind four unresolved gates: no OFAC transaction licence has been issued, Italian Golden Power approval is conditional only (with antitrust review pending), antitrust clearance is outstanding, and regulatory alignment between US and Italian timelines remains unresolved. Seven extensions without a close confirm the pattern is managed stasis.

ISAB was built in the 1970s and passed through several ownership phases before Lukoil acquired a controlling stake in the mid-2000s via Lukoil International GmbH. Following Russia's February 2022 invasion of Ukraine, GOI Energy assumed administrative management under Italian government oversight. With nameplate throughput capacity of approximately 320,000 Barrels Per Day, ISAB processes predominantly sour and medium-grade Mediterranean crude 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 southern European products market.

Ludoil Energy signed a purchase agreement with GOI Energy on 18 May 2026 for a 51% first-phase stake. Italy's energy minister signalled conditional Golden Power approval on 4 June 2026, subject to final conditions and antitrust review. A separate US OFAC transaction licence, required before any funds could legally change hands, has not been issued during any of the seven monthly renewals of the GL 131 series. OFAC's FAQ 1224 conditions require Ludoil to completely sever the holding from Lukoil, park funds in a US-jurisdiction blocked account, and provide no upfront value to Lukoil, the zero-recourse structure that remains the structural obstacle.

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

What is Golden Power and why does it apply to ISAB?

Golden Power is Italy's national-security screening regime for foreign acquisitions of strategic assets. ISAB qualifies because it supplies a substantial share of Italy's domestic refined products. Italy signalled conditional approval for Ludoil's acquisition on 4 June 2026.Source: European Oil Markets briefing

What does OFAC General Licence 131F cover for ISAB?

GL 131F authorises negotiation and contingent contracts for the sale of Lukoil International GmbH's European refining assets, including ISAB, through 27 June 2026. A separate OFAC transaction licence is required before any funds can move.Source: European Oil Markets briefing

Will the ISAB Priolo refinery sale close before 25 July 2026?

As of 30 June 2026, four gates remain outstanding: OFAC transaction licence (never issued), Italian Golden Power final order, antitrust clearance, and regulatory alignment. Seven consecutive monthly extensions without a close suggest a further extension is more likely than an imminent close.Source: European Oil Markets briefing

What is the capacity and crude diet of the ISAB refinery?

ISAB at Priolo Gargallo has nameplate capacity of approximately 320,000 Barrels Per Day. It processes predominantly sour and medium-grade crude from North Africa and the Middle East, producing petrol, diesel, jet fuel, fuel oil, and petrochemical feedstocks for the Mediterranean market.Source: European Oil Markets briefing

How the World Sees Them

Brussels views a swift ownership transfer as preferable to prolonged Russian control of a major Med refinery; seven consecutive extensions without a close expose the structural gap between sanction design and deal mechanics.

Italy

ISAB supplies a substantial share of Italy's domestic refined products; the Italian government has maintained administrative oversight since 2022 precisely to prevent supply disruption if sanctions force a halt to operations.

United States

OFAC's seven-extension pattern reflects Washington's preference for managed divestment over hard closure; the blocked-account condition in FAQ 1224 signals that no proceeds may flow to Lukoil under any deal.
