Kazakhstan Seeks Caucasus Pipeline Alternatives After Black Sea Drone Strikes
Repeated drone attacks on the CPC terminal at Novorossiysk have pushed Astana into talks over Azerbaijani and Turkish routing, putting roughly 2% of global oil supply under sustained threat.
Kazakhstan is in active discussions to divert part of its crude exports onto pipelines through Azerbaijan, Georgia, and Turkey, after drone strikes forced the Caspian Pipeline Consortium's Black Sea marine terminal offline for a week, oilprice.com reported on August 10 (2026-08-10). ICE Brent crude front-month held at $90.70 a barrel as of August 17 (2026-08-17), with the export risk still unresolved.4
The CPC terminal at Novorossiysk is Kazakhstan's dominant export outlet. Ship-tracking data compiled by Bloomberg put throughput at about 1.8 million barrels a day in May and June, which the CPC described as nearly 2% of global supply. More than 80% of Kazakhstan's crude flows through the 1,500-kilometer pipeline that runs from the Tengiz oilfield across southern Russia to the coast. The route's geography, running entirely through Russian-controlled territory, is the exposure Astana is now working to reduce.2,3
The shutdown began during the week of July 20 (2026-07-20). Reuters data showed Kazakhstan's oil and gas condensate production fell to 133,200 metric tons, or roughly 1 million barrels per day, on Sunday July 26 (2026-07-26), down from an average 2.16 million bpd in June. Production dropped by more than half in a single disruption.3
The CPC terminal reopened the following Monday (2026-07-27), with vessels chartered by Chevron's TengizChevroil among the first to resume loadings. Rigzone described the restart as a step that may ease one of the market's major supply worries. Chevron and ExxonMobil hold minority stakes in the CPC; the Russian Federation is the largest single shareholder, at 24%.2,4
A restart is not a solution. Drone attacks on Black Sea shipping have persisted as a feature of the Russia-Ukraine conflict, and the Novorossiysk terminal's vulnerability has not changed. Kazakhstan's response, as reported by oilprice.com, is to evaluate pipeline capacity through Azerbaijan, Georgia, and Turkey, routing crude westward via the Caucasus rather than across southern Russia.4
The scale of CPC's dominance makes any rapid diversion difficult. It handles more than 80% of Kazakhstan's crude, and the Caucasus alternatives, anchored primarily by the Baku-Tbilisi-Ceyhan system, were built to carry Azerbaijani and limited Caspian volumes, not to absorb a meaningful share of Kazakh throughput. Reconfiguring that capacity at scale would take time and investment.4,3
Kazakhstan's production trajectory sharpens the exposure. OPEC's Annual Statistical Bulletin put the country's crude output at 1.78 million bpd for 2025, up 239,000 bpd on the year. Reuters data placed June 2026 output at 2.16 million bpd before the shutdown. The gap between those two figures is wide enough to warrant scrutiny — it may reflect continued output growth through 2026, different measurement methodologies, or both — and neither resolves cleanly. A country producing above 2 million bpd with 80% of its exports running through a single contested terminal carries acute concentration exposure regardless of which number is correct.1,3
The episode also intensifies OPEC+ frictions that predated the drone campaign. Kazakhstan has consistently exceeded its quota, arguing that output from technically complex, Western-operated fields cannot be easily modulated. A forced shutdown at Novorossiysk delivered the cuts that voluntary compliance has not. Analysts noted to the Astana Times that the situation highlights long-standing disagreements within the alliance over quota allocations and capacity expansion.1
For traders, the near-term question is whether drone attacks on CPC infrastructure intensify and whether Astana's route-diversification talks produce committed capacity on the Caucasus corridor. A second comparable shutdown, pulling more than 1 million bpd off the market for another week, would land as a supply event in a market already absorbing Strait of Hormuz pressure; the IEA estimated nearly 20 million barrels of oil per day passed through the strait in 2025. ICE Brent front-month above $90 as of August 17 (2026-08-17) suggests the scenario has not been fully discounted.4,1
