18 Russian refineries were targeted in July alone, including the country's largest (Omsk), driving Russian oil refining to its lowest level in more than 24 years .
Fresh long-range drone strikes continued into early August:
These strikes force more crude that would have been refined domestically onto export markets, but the export infrastructure cannot easily absorb the surplus .
Black Sea port disruptions: Russia's largest Black Sea oil terminal, Sheskharis at Novorossiysk (handling ~650,000 bpd, or about one-fifth of seaborne crude exports), suspended loadings from July 21 due to a surge in Ukrainian drone and maritime drone threats . Loadings resumed days later, but the disruption was a stark warning
.
Dirty tanker loadings in the Black Sea/Sea of Azov plunged 62% in the last two weeks of July, averaging just 0.98 million bpd, down from 2.59 million bpd earlier in the month, per BIMCO data .
Freight rates for Urals crude to India have jumped ~50% since mid-July as shipowners avoid Russian Black Sea ports due to security risks . Russian shipping group FESCO suspended new shipments via the Black Sea
.
The Bank of Russia noted that redirecting freed-up crude from damaged refineries to exports is limited by transport and port infrastructure capacity .
Exports via Baltic ports are set to rise 4% in August as sellers try to shift more crude to Asia, but tanker availability is tightening across all routes .
A paradoxical squeeze is emerging: drone attacks on refineries create more crude for export, but Black Sea security threats deter tankers, raise freight costs, and push loadings to a seven-week low. Crude exports fell to 3.9 million bpd in the four weeks to Aug. 2 .
Industry sources expect output to slide again in August as new refinery outages compound existing export logistics constraints, with tanker capacity in the Black Sea acting as the tightest bottleneck . The production rebound above 9 million bpd appears fragile, and the interplay of drone warfare, refinery damage, and maritime security will likely keep Russian oil output under pressure in the near term.
