• Gazprom (GAZP.ME) Neft's Moscow refinery has suspended crude processing following a Ukrainian drone attack that sparked fires at both primary distillation units.
  • The outage could last several weeks, according to people familiar with the matter, potentially squeezing fuel supplies to Russia's largest urban market.
  • The strike adds to a broader Ukrainian campaign targeting Russian refining capacity, with multiple facilities damaged in recent weeks.

Gazprom Neft's Moscow refinery has halted crude processing after a Ukrainian drone attack caused fires at both of its primary distillation units, according to sources familiar with the matter. The incident, which occurred earlier this week, has forced the company to shut down operations at the Kapotnya facility in southeast Moscow.

The refinery, which processes approximately 230,000 barrels per day (bpd) of crude, is a critical supplier of gasoline, diesel, and other refined products to the Moscow region. In 2024, it produced 3.2 million tons of diesel and 2.9 million tons of gasoline, according to company data. Repairs to the damaged units could take several weeks, the sources said, though an exact timeline has not been determined.

The attack is part of a sustained Ukrainian drone campaign aimed at disrupting Russia's energy infrastructure, which Kyiv views as a means to reduce resources available to fund the war. In recent weeks, strikes have targeted refineries in Kirishi, Volgograd, Ryazan, Syzran, Saratov, and Yaroslavl, among others. According to Reuters, half of Russia's six largest diesel-producing refineries have either halted or sharply reduced output following drone damage.

A Growing Risk to Fuel Supply

The cumulative effect of these strikes is beginning to strain Russia's refining network. In June, the country's refinery throughput fell to 8.7 million bpd, down 3.8 million bpd—or 30%—from a year earlier, marking the lowest level since May 2004, according to International Energy Agency data cited by Reuters. Gasoline output has fallen by roughly a fifth, leading to regional shortages and forcing Russia to import fuel.

The Moscow refinery's outage is particularly sensitive because it is the largest fuel supplier to the capital region. With the plant offline, Russia will likely rely on inventories, reroute supplies from other refineries, and potentially increase imports to meet demand. However, longer distribution routes and diverted output could raise freight, storage, and wholesale costs, even if retail price controls initially mask the impact at the pump.

Gazprom Neft, a key subsidiary of state-owned Gazprom, has not publicly commented on the extent of the damage or repair timeline. The company's 2025 financial results showed revenue rising 16.5% to RUB 4.1 trillion, while adjusted EBITDA increased 5.8% to RUB 1.39 trillion. However, profit attributable to shareholders fell 25.2% to RUB 479.45 billion, partly due to operational challenges.

Broader Implications

The strike on the Moscow refinery underscores Ukraine's ability to reach heavily defended infrastructure near the Russian capital. While Russian authorities reported a major drone assault on September 20, precise details on the number of drones launched or intercepted remain unverified. Ukraine's leadership has confirmed strikes on oil and logistics facilities but has not commented on specific targets.

The attacks also have global market implications. Russian refinery outages remove diesel and other middle distillates from export availability, tightening an already strained global diesel market. A prospective energy-infrastructure truce, if pursued, would not necessarily reverse the tightness created by sustained disruption, analysts note.

For Russia, the political challenge is twofold: managing domestic fuel shortages and maintaining security credibility. Fuel shortages, rationing, and long queues at filling stations can affect households, freight operators, farmers, and small businesses across Russia's 11 time zones. The strikes have already contributed to higher fuel prices and regional supply gaps.

Gazprom Neft's Moscow refinery was previously targeted in June, when drone strikes damaged the CDU-6 unit and caused multiple fires. At that time, Reuters reported that repairs would take at least six months, meaning the plant was unlikely to resume production in 2026. The latest attack may have further damaged the facility, but it is not yet clear whether it extended the existing repair timeline.

A recent precedent is the Ryazan refinery, which was offline for roughly two to three weeks after a July strike. However, Moscow's damage appears more severe because multiple units were affected. The International Energy Agency has indicated that major damage to complex refinery equipment can require many months to repair, especially given sanctions-related constraints on specialized equipment and technical services.

What to Watch

In the short term, Russia will likely prioritize supplying Moscow and other politically sensitive regions through stock drawdowns, rerouting fuel, and reduced exports. Wholesale availability and regional logistics are expected to remain strained while multiple refineries are damaged concurrently.

Longer term, recurrent drone attacks may lead Russia to increase spending on air defense, hardening, repair capacity, and fuel-distribution redundancy—costs that can erode refinery profitability even after physical capacity returns. The principal strategic risk is cumulative: each individual outage may be manageable, but simultaneous hits across a concentrated set of high-output diesel refineries can produce persistent shortages and weaken Russia's export flexibility.

Gazprom Neft did not immediately respond to a request for comment. The company's Moscow refinery outage is another potential pressure point for Russian fuel supply, and the situation remains fluid.
