Orlen Lietuva, previously known as Mažeikių Nafta, functions as a subsidiary of the Polish corporation PKN Orlen and operates the Mažeikiai oil refinery, which is the only refinery facility within the Baltic States.

Refinery

Located near Mažeikiai, the Mažeikiai refinery is designed to process up to 15 million tons of crude oil each year; however, its actual throughput generally amounts to approximately 8 million tons. The refinery enhances operational efficiency by utilizing the remaining capacity for alternative feedstocks. Historically, it depended on Russian crude supplied through the Druzhba pipeline, but this pipeline branch has been non-operational since July 2006, leading to a transition toward crude deliveries via the Būtingė oil terminal.

Pipeline system

The pipeline infrastructure overseen by Mažeikių Nafta extends roughly 500 kilometers and includes pumping stations in proximity to Biržai and Joniškis. This network comprises crude oil pipelines servicing both the Mažeikiai Refinery and the Būtingė Terminal, a crude oil conduit to Ventspils, as well as a diesel fuel products pipeline directed to the same port. Construction of these pipelines commenced in 1966, with operations launching in 1968. The entity Naftotiekis, established in 1992 to manage Lithuania’s pipelines, was integrated into Mažeikių Nafta in 1998.

Būtingė Marine Terminal

Situated on Lithuania’s Baltic Sea shoreline near Būtingė, the Būtingė oil terminal—owned by Mažeikių Nafta—is positioned within an ice-free maritime zone. Created in 1995 under the name Būtingės Nafta to oversee terminal construction and management, it merged with Mažeikių Nafta three years later. The terminal commenced tanker loading operations in 1999, initially handling crude oil from YUKOS. It possesses an export capacity reaching up to 14 million tons per year and is also capable of functioning as an import facility.

The terminal complex features a crude oil pipeline connecting it directly to the Mažeikiai Refinery, alongside onshore infrastructure including storage tanks and equipment, an offshore pipeline, and a single point mooring (SPM) buoy located seven kilometers offshore. To ensure environmental safety, the terminal operates a monitoring program encompassing sea and groundwater testing paired with a computerized leak detection system.

Privatization

In 1999, the Lithuanian government privatized the company by selling it to the US-based Williams Companies. Following financial setbacks, Williams transferred ownership to Russian enterprise Yukos. After Yukos encountered substantial tax claims and financial collapse in 2003, it initiated asset divestment including Mažeikių Nafta.

Prospective buyers from Russia, Kazakhstan, and Poland showed interest; however, the proposal from Polish firm PKN Orlen was selected for its superior financial terms and alignment with Lithuania’s strategic objective to prevent Russian control over vital energy assets due to national security considerations. During negotiations, Russia ceased operation of the sole land pipeline supplying the refinery—a move perceived as applying pressure on Lithuania.

By June 2006, PKN Orlen agreed to acquire Yukos International's 53.7% stake and shortly thereafter concluded an agreement with the Lithuanian government to purchase an additional 30.66%. The European Union granted approval for this transaction in November 2006, citing no major competition issues. The acquisition was finalized on December 15, 2006, with PKN Orlen disbursing US$1.492 billion to Yukos International and US$851.8 million to the Lithuanian government.

Suspension of Druzhba pipeline's Lithuanian segment

On 29 July 2006, Russia ceased supplying oil to the Mažeikių refinery in Lithuania after an oil spill occurred on the Druzhba pipeline within Russia's Bryansk oblast, close to the junction serving Belarus and Lithuania. Transneft projected that repairing the damage would require nearly two years. Although Russia attributed the halt to technical complications, Lithuania claimed it was a retaliatory move linked to the sale of the refinery to Polish firm PKN Orlen, intended to block Russian acquisition attempts. Consequently, crude oil shipments from Russia were redirected through the Būtingė oil terminal.

Fire incident

At approximately 2:30 pm on October 12, 2006, a significant fire erupted at the refinery, likely triggered by a leak. The blaze was largely controlled by 8 pm, with residual spot fires persisting into the following day. The event resulted in the collapse of a vacuum tower, multiple oil leaks, and explosions spanning an area of about 800 square meters. Emergency services deployed 23 firefighting units; flames reportedly soared up to 150 meters and were visible from several kilometers away, with smoke drifting toward Latvia. Fortunately, no injuries were reported.

The estimated financial impact included damages around 38 million Euros and an additional 30 million Euros lost due to production interruptions. Despite early media rumors suggesting that PKN Orlen might reconsider its acquisition because of the fire, the transaction proceeded without alteration. Speculation emerged that the fire could have been an act of industrial sabotage connected to Russian energy interests dissatisfied with losing control over the refinery. Notably, Russian Duma deputy chairman Konstantin Kosachev remarked just hours before the fire that "instability will continue to plague the refinery until the Lithuanians finally realize which partners one should choose."
