**Summary**: Satellite imagery indicates all four atmospheric-vacuum distillation units at Russia’s Orsk refinery were hit in a Ukrainian drone strike, implying a near-complete shutdown. This tightens Russian product supply further, supporting European diesel cracks and global refining margins, and may add modest upside to crude benchmarks via lost runs and higher Russian export restrictions.

## Detail

Exilenova+ satellite imagery now suggests that all four atmospheric-vacuum distillation (AVT) units at Russia’s Orsk refinery were struck in the recent Ukrainian attack. If confirmed, this effectively takes the plant’s primary crude distillation offline. Orsk’s capacity is roughly 6–7 mtpa (120–140 kb/d), and combined with earlier Ukrainian strikes on Russian refineries and port infrastructure, this marks one of the more operationally significant single-site hits in recent months.

The immediate impact is on Russian domestic product availability, particularly diesel and gasoline, in a market where there are already reports of a tightening fuel balance and Russia sourcing gasoline from India. A full outage at Orsk removes on the order of 120 kb/d of crude processing; assuming typical yields, this could mean 40–50 kb/d less diesel and 25–30 kb/d less gasoline until repairs. Moscow is likely to prioritize internal supply by curbing some product exports and/or adjusting crude flows to other plants. That tends to tighten seaborne product availability, particularly into Europe, Africa, and Latin America, and support diesel cracks and prompt margins.

For crude benchmarks, the directional bias is mildly bullish. Lost refinery runs can be superficially bearish for crude demand, but in the Russian case, prior episodes have often been associated with export and logistics bottlenecks, wider risk premia on Russian physical streams, and stronger refined product pricing feeding back into crude. In addition, the strike underscores that Ukraine retains the capability and intent to conduct deep strikes against Russian energy infrastructure, compounding existing risks around Novorossiysk and other Black Sea assets.

Historically, Russian refinery outages from drone attacks (e.g., Tuapse, Ryazan, and others in 2024) contributed to 5–10% spikes in regional diesel cracks and occasional outperformance of European refining equities. A similar pattern is plausible here. The impact is likely to be medium duration: weeks to months of constrained capacity at Orsk, with structural risk premia for Russian downstream and Black Sea logistics persisting as long as Ukrainian long-range strike capability remains intact.
