Ukraine Drone Strike Shuts CPC Novorossiysk Terminal, Cutting Tengiz Output to 406,000 Barrels a Day and Threatening 15 Percent of EU Crude Imports

Ukraine's drone campaign reached Kazakhstan's main crude export artery on July 21, 2026, when the Caspian Pipeline Consortium halted crude intake at its Novorossiysk Black Sea terminal. The Tengiz field, which had averaged 925,000 barrels a day through July, fell to 406,000 barrels a day after the shutdown. As of July 23, no authoritative confirmation of a full restart had emerged, according to OilPrice.com.

A Chokepoint Supplying 15 Percent of EU Crude

The CPC system carried an average of 1.7 million barrels a day from Kazakhstan's Tengiz and Kashagan fields to Novorossiysk over the three months before the attack. Approximately 1.42 million barrels a day flow onward to European refiners, representing 15 percent of EU crude imports in June 2026. Kazakhstan routes 80 percent of its crude exports through the single terminal, per OilPrice.com data, leaving no viable alternative at scale. Total Kazakh output dropped to 1.63 million barrels a day this week from a July average of 2.07 million barrels a day.

TengizChevroil: The Revenue Math Behind the Production Cut

The Tengiz field operates through TengizChevroil, a joint venture in which Chevron holds 50 percent, ExxonMobil holds 25 percent, KazMunayGas holds 20 percent, and LukArco, a Lukoil subsidiary, holds 5 percent. The outage leaves the consortium producing 519,000 fewer barrels each day than its July average. WTI crude settled at $90.47 per barrel on Friday's CME close, per TradingEconomics. At that price, the daily production gap costs the joint venture $46.95 million in gross revenue each day. Chevron's 50 percent stake absorbs $23.5 million of that shortfall; ExxonMobil's 25 percent stake absorbs $11.7 million.

Kashagan's NCOC Partners Face the Same Export Bottleneck

Kazakhstan's other major producing field, Kashagan, also funnels output through the CPC route to Novorossiysk. The North Caspian Operating Company operating Kashagan counts ExxonMobil, Shell, TotalEnergies, Eni, KazMunayGas, CNPC, and Inpex among its shareholders. All seven partners depend on the same Novorossiysk terminal to move Caspian crude to market. Any sustained CPC outage forces each operator to throttle production or build crude into storage until the terminal reopens.

A Repeat Strike on Proven Infrastructure

This attack follows a November 2025 drone strike that damaged the same facility's single-point mooring buoy and temporarily reduced CPC throughput. That earlier strike was repaired within weeks before operations resumed. The July 21 attack arrived when Kazakhstan was already pumping 2.07 million barrels a day on its July average. This week's output of 1.63 million barrels a day marks a decline of 440,000 barrels a day from that baseline, per OilPrice.com.

Hormuz Adds a Second Chokepoint to the Supply Squeeze

The CPC outage coincides with record-low tanker activity through the Strait of Hormuz. Only one tanker crossed the strait on July 24, the lowest single-day count since May 7, per OilPrice.com. ING analysts warned that "further escalation in the Persian Gulf and fears of a widening conflict are putting a significant amount of oil supply at risk." Crude prices surged above $100 per barrel during the week, per OilPrice.com market reporting, before Brent settled at $98.38 on Thursday, July 24, per TradingEconomics. European and Asian buyers now compete for West African, North Sea, and US Gulf Coast crude to fill the gaps from both corridors.
