Ukrainian Drone Strikes Halt Russian Oil Refinery and Major LPG Plant
8/12/2026, 9:55:01 PM
Immediate Impact of the Attacks
- Russia’s Orsknefteorgsintez oil refinery stopped processing on August 11 after a fire triggered by a Ukrainian drone strike.
- The Zapsibneftekhim petrochemical complex in Tobolsk, western Siberia, was shut indefinitely after a drone attack earlier in the week, with operations halted while damage assessments continue.
Background & Context
- Throughout the current year, Ukraine has stepped up drone attacks on Russian energy infrastructure, targeting refineries, pipelines and ports and contributing to a domestic fuel shortage.
- Orsk refinery’s name-plate capacity is 5.76 million metric tons per year (about 115,200 bbl/d). In 2024 it processed 4.2 million t of crude, yielding 1.8 million t of diesel, 600,000 t of gasoline, 500,000 t of bitumen and 200,000 t of fuel oil.
- Zapsibneftekhim is Russia’s largest liquefied petroleum gas (LPG) facility, producing roughly 6 million t of LPG annually—about 40 % of the country’s total output. Approximately half of this LPG serves as feedstock for Sibur’s integrated petrochemical operations in Tobolsk.
Data & Statistics
- Orsk’s processing capacity translates to roughly 115,200 bbl/d.
- Prior to the attack, the Tobolsk loading point regularly supplied around 4,000 metric t per day of technical propane-butane mix (PBT) to the market.
- Zapsibneftekhim’s annual LPG output of 6 million t underpins a significant share of domestic LPG availability and downstream petrochemical feedstock.
Official Statements & Responses
- The Ukrainian military confirmed the strike on the Orsk refinery.
- Tyumen region Governor Alexander Moor said a fire broke out at an industrial facility after drones crashed, but he did not identify the specific plant.
- Forteinvest, the owner of the Orsk refinery, declined to comment.
- Sibur also declined to comment on the situation at its Zapsibneftekhim complex.
Conflicting Reports & Gaps
- Reuters did not name the Tyumen-region facility, while the Moscow Times and Chemanalyst linked the attack to the Zapsibneftekhim plant, describing it as Russia’s largest petrochemical complex.
- Ukrainian officials did not claim responsibility for the Tyumen attack, unlike the Orsk strike that was confirmed by Ukraine’s military.
- No details on injuries or the precise extent of damage have been released by Russian authorities.
Market Impact
- The day after the Tobolsk attack, no LPG volumes were offered for delivery on the St. Petersburg International Mercantile Exchange (SPIMEX), indicating an immediate supply shortfall.
- Analysts anticipate near-term bullish pressure on LPG and propane-butane prices in Russia and neighboring markets, with potential spill-over effects on propylene and polypropylene prices if the outage persists.
What’s Next
- Both facilities remain offline while owners assess damage and plan repairs. The length of the shutdown will shape longer-term effects on domestic LPG balances and the broader Russian petrochemical value chain.
