**Summary**: Ukrainian long-range drones struck Lukoil’s Kstovo refinery in Nizhny Novgorod, with the AVT‑6 crude distillation unit reported burning. This reinforces the campaign against Russian refining capacity, tightening regional product balances and supporting refined product cracks and Brent time spreads.

## Detail

Reports indicate Ukrainian long-range drones have hit the Lukoil‑Nizhegorodnefteorgsintez (Kstovo) refinery in Russia’s Nizhny Novgorod Oblast, with an AVT‑6 atmospheric/vacuum distillation unit on fire. This facility is one of Russia’s larger refineries (rough order ~15–17 mtpa / 300–340 kb/d range), and damage to a primary crude unit materially affects throughput if the outage is prolonged.

While the exact capacity of the AVT‑6 line is not yet confirmed in the reports, a single AVT train at a complex Russian refinery typically runs on the order of 80–120 kb/d. Even a partial shutdown or precautionary curtailment of operations for safety and inspections could temporarily remove tens of thousands of barrels per day of crude runs and associated exports of diesel, gasoline, and vacuum gasoil. This comes on top of prior Ukrainian strikes on Russian refineries, which have already taken several hundred thousand barrels per day of capacity intermittently offline in 2024–2026.

Market impact skews toward refined products rather than crude. Russia is a key exporter of diesel and other middle distillates into global markets (including via re‑routing and blending channels). Additional disruption risk at a large inland refinery supports European diesel cracks, high-sulfur fuel oil, and potentially gasoline if secondary units are also affected. Brent and Urals benchmarks are likely to see a modest bullish impulse via stronger product cracks and a higher perceived risk premium on Russian downstream infrastructure, even if crude exports per se are not immediately curtailed.

Historical precedent: previous confirmed Ukrainian drone attacks that clearly disabled specific Russian refineries have triggered >1–3% intraday moves in European gasoil and often 1–2% in Brent, especially when fires and unit shutdowns were confirmed. The repetition of such strikes has a cumulative structural effect by raising insurance, operating, and maintenance risk premia on Russian products.

Assuming the fire is contained within hours and the unit can be partially restored within weeks, the direct physical disruption is likely transient (days–weeks). However, the ongoing campaign against Russian refineries adds a more durable risk premium to refined products and to cracks and supports backwardation in the Brent complex.
