DISAGREEMENT on capacity between two ORLEN-published sources, both opened 2026-09-22.
ORLEN Lietuva's own refinery page states 'The design capacity of the Mazeikiai Refinery is 10 million tonnes of crude oil per year' and adds that the efficient operating volume under current conditions is 8 million tonnes annually.
ORLEN's 2023 Integrated Report states 'ORLEN Lietuva refinery in Mazeikiai, with an annual production capacity of 10.2 million tonnes, being the only refinery in the Baltic states (Lithuania, Latvia and Estonia)'.
The 10 Mt/a design figure from the site operator is used in the capacity fields; the 10.2 Mt/a group figure is dated 2023. capacity_bpd is EMPTY because neither ORLEN source prints barrels per day and no tonnes-to-barrels conversion was made.
Quoted verbatim from the source notes of this row. Nothing is averaged.

This refinery's crude intake by origin: UNKNOWN
Which crude oil Mazeikiai Refinery (ORLEN Lietuva) runs on is not published, so it is UNKNOWN. Refinery-level crude intake by origin is not public in most of Europe, and we do not allocate a national figure across refineries.
Unknown
National · LithuaniaNational context — not this refinery's own figure
Mazeikiai Refinery (ORLEN Lietuva) is the only operating crude oil refinery we hold for Lithuania, so the national crude-import figure is the closest public evidence of what it runs on. In June 2026, Lithuania's crude imports came mainly from Norway (38%), Saudi Arabia (38%) and the United States of America (24%). This is an inference, not a reported intake: crude produced in Lithuania itself, stock changes and re-exports are not separated out in the import figures.
Does the national figure describe this refinery?Inferred · lowLowOnly as an inference: it is the country's only operating crude refinery we hold.

Outages and maintenance
Planned and unplanned shutdowns we can cite. There is no public register for EU refineries, so an empty list is not a clean record.

Strait of Hormuz: Lithuania's direct crude exposure (national)
The share of the country's crude imports that came from origins loading inside the Persian Gulf. Measured per country, never per refinery.
National · LithuaniaNational context — not this refinery's own figure
National figure, not specific to this refinery: Between 0% and 29% of Lithuania's crude oil imports in July 2026 came from Hormuz-dependent origins. No point estimate is published: the origins concerned export from both inside and outside the Persian Gulf and the split per period is not public. The range describes the country's crude imports; which of them reached Mazeikiai Refinery (ORLEN Lietuva) is not published. Calculated

Source notes for this refinery (verbatim)
DISAGREEMENT on capacity between two ORLEN-published sources, both opened 2026-09-22. ORLEN Lietuva's own refinery page states 'The design capacity of the Mazeikiai Refinery is 10 million tonnes of crude oil per year' and adds that the efficient operating volume under current conditions is 8 million tonnes annually. ORLEN's 2023 Integrated Report states 'ORLEN Lietuva refinery in Mazeikiai, with an annual production capacity of 10.2 million tonnes, being the only refinery in the Baltic states (Lithuania, Latvia and Estonia)'. The 10 Mt/a design figure from the site operator is used in the capacity fields; the 10.2 Mt/a group figure is dated 2023. capacity_bpd is EMPTY because neither ORLEN source prints barrels per day and no tonnes-to-barrels conversion was made. Commissioned 1980 per the operator page. Connections per the ORLEN Lietuva terminal-and-pipelines page: the Butinge terminal 'can export up to 14 million tons of crude oil a year' and includes 'a crude oil pipeline, which connects the facility with the Mazeikiai Refinery' (Mazeikiai-Butinge, 91.5 km); the Polotsk-Birzai-Mazeikiai pipeline (built 1979, 225.5 km Lithuanian section, 720 mm, 16 million tons a year) also reaches the refinery, with the Mazeikiai-Birzai leg given as a 28-inch line of 16.2 million tons a year. The refinery page notes that Russian crude via the Druzhba trunk pipeline stopped in July 2006 and that crude now arrives mainly via Butinge, plus rail and truck.
