CPC Pipeline Shuts Again as Kazakh Output Halves After Novorossiysk Drone Strikes
Repeated Ukrainian attacks on Black Sea tankers have cut Kazakhstan's daily crude production to around 1 million barrels, raising fresh supply questions for European refiners.
The Caspian Pipeline Consortium shut down its 1,500-kilometre export line again on Thursday (2026-07-31) after Ukrainian drones struck two tankers at the Russian Black Sea port of Novorossiysk, Reuters reported, citing the company operating the pipeline. The closure is the latest in a sequence of disruptions that have made this export corridor one of the most unreliable crude arteries feeding European and Asian buyers.8
Kazakhstan's output took a sharp hit immediately. Industry data cited by Reuters showed Kazakh oil and gas condensate production fell to 133,200 metric tons per day, roughly 1 million barrels per day, on Sunday (2026-07-26), down from an average 2.16 million barrels per day in June. That is more than a 50% reduction in daily throughput from a country that ranks among the world's ten largest oil producers.8,6
The CPC pipeline is Kazakhstan's primary export route, carrying more than 80% of the country's crude from the giant Tengiz oilfield across southern Russia to Novorossiysk. Losing it, even briefly, removes more than 1 million barrels per day from the market, according to the packet. Novorossiysk loaded more than 980,000 barrels per day in June, Bloomberg data show, representing more than 20% of Russia's total seaborne crude exports that month, per International Energy Agency figures.8,3
Urals crude was last quoted at $76.94 per barrel as of Tuesday (2026-07-29), flat on the day. The absence of an immediate spike reflects competing forces: the supply hit from the CPC closure presses upward, but weakening demand signals and a broader market environment that saw ICE Brent crude front-month at $90.15 per barrel on Tuesday (2026-07-29) cap the move. European refiners who had been leaning on Kazakh barrels as an alternative to Middle East crude now face a gap with no obvious quick replacement.8,4
Kazakhstan confirmed a halt to crude transfers at the CPC terminal on July 21 (2026-07-21) following a prior drone attack, and Rigzone reported that terminal loadings had stopped on July 20 (2026-07-20). The pattern is now established: Ukraine hits tankers or terminal infrastructure, the CPC suspends operations, Kazakh output craters within days. The cycle has repeated enough times that traders should price in elevated disruption frequency rather than treat each closure as a one-off.5,4
Ukraine has been striking Russian energy infrastructure with increasing precision. Kpler senior research analyst Nikhil Dubey noted that some drones appeared to have targeted hydrocracker units at refineries, suggesting improved targeting capability rather than opportunistic attacks. Ukraine said in mid-July (2026-07-15) that it had hit more than 100 Russia-linked ships in the Black Sea. The Moscow oil refinery halted operations after a drone attack on June 16 (2026-06-16), and Russia's NORSI refinery, which processes around 320,000 barrels per day and accounts for the bulk of Russia's second-largest gasoline production site, was also struck. Russia has since been forced to import fuel from Asia to cover domestic shortfalls.3,72
That supply pressure sits against a sanctions backdrop that was already tightening Russian crude flows. Data from Kpler analyst Sumit Ritolia estimated that US sanctions, combined with reduced purchases from India, China and Turkey, could cut Russian crude shipments by 1.4 million barrels per day in the months following October 2025, a 39% reduction from October's rate. India's state-owned firms accounted for 65% of purchases in the period before those projections, a concentration that makes the anticipated drop in purchases especially significant.1
But the bullish read on Urals is not uncontested. PVM analyst John Evans said earlier this week (week of 2026-07-27) that oil markets are "seeking good news from an arena that really is not providing any," and that geopolitical pauses do not translate directly into additional supply. Ole Hvalbye of SEB Research made the point more bluntly: "A political pause doesn't put a single extra barrel on the water right here and now." Those views were directed at the Iran situation, but the same logic applies to the CPC route — the pipeline reopening does not guarantee loadings resume cleanly or quickly.6
Industry analysts expect oil markets to remain highly volatile as the US-Iran ceasefire situation develops and as CPC operations stay uncertain. The variable most worth tracking is whether Ukraine escalates drone attacks on tankers beyond Novorossiysk, which would widen the disruption from a Kazakhstan-specific problem into a broader Russian seaborne export crisis. A second indicator is how quickly European refiners that had been sourcing Kazakh grades find replacement barrels — and at what premium to Urals they have to pay to do so.6,8
