Bulgaria's only oil refinery, Lukoil Neftochim Burgas, processed Russian crude for most of its post-Soviet history. Since March 2024, that has been banned by law. Does Bulgaria still receive oil from Russia? Does fuel in Bulgaria depend on Russian energy infrastructure? Such questions are never clearly answered in mainstream media.This article addresses both questions directly.

The refinery and its role

The Burgas refinery came online in 1963 and has been owned by Russia's Lukoil since 1999. It processes around 190,000 barrels per day and, according to industry data published by Offshore Technology, accounts for roughly 7 percent of Bulgarian GDP. It is the only large refinery in the country and supplies the majority of its domestic fuel market, along with exports to the wider Balkan region.

The ban and what replaced Russian crude

Bulgaria's parliament voted in late 2023 to end Russian crude imports at the refinery by March 1, 2024, ahead of an EU-wide derogation deadline that had extended the exemption until end-2024. From January 2024, deliveries shifted to three main sources. According to Reuters market data and traders cited by multiple outlets in January 2024, the refinery received two 70,000-tonne shipments of Kazakhstan's KEBCO grade, one 76,000-tonne cargo of Basrah Light from Iraq, 33,000 tons from Tunisia, and a 50,000-tonne CPC Blend cargo. In 2022, Lukoil had stated publicly that the refinery could only work with Russian Urals grade crude, a claim that reflected the plant's technical configuration rather than any legal constraint.

The Kazakhstan question

KEBCO stands for Kazakhstan Export Blend Crude Oil. Kazakhstan introduced the name in June 2022, when its state oil company KazMunayGas rebranded crude exported via Russian infrastructure to separate it from Russian Urals in commercial documents, as reported by S&P Global Commodity Insights at the time of the rebranding. Before that, Kazakh oil transiting Russian pipelines was marketed simply as Urals.

The physical reality has not changed with the name. KEBCO travels through the Russian Transneft pipeline system from Kazakhstan to Russian Black Sea ports before loading onto tankers. S&P Global confirmed in 2022 that physically, Urals and KEBCO blends are identical. The difference is documentary: the certificate of origin shows Kazakhstan.

Russian companies, including Transneft and Rosneft, hold around 44 percent of the Caspian Pipeline Consortium, the main export infrastructure for Kazakh oil, according to a 2022 analysis published by the Jerusalem Post. Russia collects transit fees on every barrel moved through this system. The pipeline has been disrupted three times by Russia since March 2022, according to the same report.

None of this makes KEBCO illegal under current sanctions. Both the US and EU have confirmed Kazakh crude is not targeted by measures against Russia. But the argument that Bulgarian fuel is now independent of Russian energy infrastructure is difficult to sustain when a significant share of replacement crude exits from Russian ports through a partly Russian-owned pipeline.

US sanctions and the derogation

On October 22, 2025, the Trump administration added Lukoil and Rosneft to the US Treasury's Specially Designated Nationals list, citing Russia's continued war against Ukraine, as reported by OFAC. The designations cut the companies off from the dollar-based financial system, threatening to shut down the Burgas refinery within weeks.

Bulgaria responded by passing emergency legislation, appointing a state administrator over the four Bulgarian Lukoil subsidiaries, and requesting a sanctions exemption from OFAC. Washington granted it. General License 130, issued November 14, 2025, authorized transactions with Lukoil Neftochim Burgas, Lukoil Bulgaria, Lukoil Aviation Bulgaria, and Lukoil Bulgaria Bunker through April 29, 2026, according to the OFAC document. A parallel UK license covers operations through August 13, 2026, according to Bulgaria's Ministry of Energy.

A core condition of the derogation is that no money flows from the Bulgarian subsidiaries back to Lukoil's Russian parent. The state administrator, Rumen Spetsov, cut ties with Litasco SA, the Swiss trading arm that had previously handled crude supply and routed profits offshore. According to OilPrice.com citing Bulgarian official statements, the refinery saved 8 million US dollars in two months from the removal of Litasco's commission fees alone.

Does Russia still receive money?

Before November 2025 it did. Research published in December 2023 by the Centre for Research on Energy and Clean Air estimated that between 2022 and late 2023, the refinery generated roughly 2.4 billion US dollars in windfall profits by purchasing discounted Russian crude and selling refined products at market prices, with most profits transferred to Lukoil's Swiss and Dutch subsidiaries rather than paid as tax in Bulgaria. The Wikipedia article on the refinery notes that Lukoil Neftohim Burgas had never paid tax in Bulgaria prior to 2022, as profits were sent to the parent company in Switzerland.

After the state administrator took control in November 2025, the direct flow of operating profits to Russia has been cut. Lukoil remains the legal owner, however, and any eventual sale of the Bulgarian assets will result in a payment to Lukoil PJSC, a Russian company. OFAC approval is required for any sale to proceed. As of late March 2026, OFAC extended the negotiation window to May 1, 2026, under General License 131D, according to legal analysis published by FesenkoLaw.

The modernization gap

The refinery was configured to process heavy, sour Urals-type crude. According to an Interfax report citing the Financial Times, fully reconfiguring it to process lighter alternative grades is estimated to require around 500 million euros in capital investment. That work has not been done. Traders cited by Reuters in January 2024 noted that the market for sour-grade alternatives to Urals in Europe was tight and more expensive, and that the switch raised costs at the plant.

Where things stand

The crude entering Burgas since March 2024 is legally non-Russian. The Bulgarian state now controls day-to-day operations. Direct profit transfers to Russia have stopped under the terms of the US derogation.

At the same time, the primary replacement crude grade travels through Russian-owned and Russian-operated infrastructure, generating transit revenue for Russia. The refinery has not been reconfigured for the grades now feeding it. And Lukoil retains legal ownership, meaning the eventual sale proceeds will flow to a sanctioned Russian company, pending OFAC authorization of a specific buyer.
