Oil majors operating Kazakhstan’s Kashagan field filed for international arbitration over a disputed $5 billion environmental fine, escalating tensions with the government after a local court upheld the penalty in December 2025. The dispute centers on sulfur-storage violations, though the consortium claims full compliance. Shell stated dialogue failed, forcing arbitration under international treaties, while Kazakhstan’s Ecology Ministry declined comment. Kazakhstan simultaneously initiated arbitration to reclaim two untapped fields—Aktoty and Kairan—seeking their return to state control after years of stalled development by the consortium. The conflict is part of a broader $166 billion legal battle over Kashagan, including claims of lost revenue, corruption, and cost recovery, straining relations with foreign investors like Shell, which paused new Kazakh investments pending resolution. Recent rulings, including a $4 billion loss for Karachaganak operators, highlight Kazakhstan’s aggressive push to renegotiate terms with oil majors amid its growing role as a key European energy supplier post-Ukraine war.

Multiple arbitrations have been underway on different issues for several years, with tens of billions of dollars potentially at stake.Kazakhstan’s government recently told the companies that it’s taking a separate disagreement over two untapped oil deposits near Kashagan to arbitration, people familiar with the matter said. The country has been seeking the return of the fields, called Aktoty and Kairan, to state ownership for several years, amid a push to ensure all of its resources are fully developed.Get the latest headlines, breaking news and columns.By signing up you consent to receive the above newsletter from Postmedia Network Inc.A welcome email is on its way.

The nation’s importance has only increased as the continent moved away from Russian energy supplies following the 2022 invasion of Ukraine.The latest claims add to a wider $166 billion dispute between Kazakhstan and the oil majors over Kashagan. The country’s authorities have multiple claims in international arbitration related to lost revenue, cost recovery, environmental violations and deals that were allegedly tainted by corruption.Most recently, the oil majors that operate the Karachaganak field suffered a partial loss in one of the arbitration cases, leaving them liable to pay as much as $4 billion in compensation to Kazakhstan’s government. The long-running legal claims are affecting the OPEC+ nation’s relationship with its international partners. Shell, which has stakes in both Kashagan and Karachaganak, will pause investment in Kazakhstan until it has more clarity on how the cases will be resolved, Chief Executive Officer Wael Sawan said on Feb. 5.The Kashagan environmental fine is related to sulfur-storage rules.

North Caspian Operating Co., the joint venture that operates the field, has been in full compliance with all laws and permits related to the chemical, the Shell spokesperson said. NCOC declined to comment. Among the other international partners in Kashagan, Eni SpA declined to comment; Exxon Mobil Corp. referred all questions to NCOC; state-run KazMunayGas National Co. declined to comment; TotalEnergies SE declined to comment; China National Petroleum Corp. could not be reached for comment during a national holiday; Inpex Corp. declined to comment. Kashagan, where international companies have invested $55 billion, has geological oil reserves of 4.5 billion tons, according to the website of the state-controlled vehicle for production-sharing agreements. Aktoty contains 156 million tons of a light oil called condensate and Kairan holds 112 million tons of crude, according to the website. The government also wants NCOC to remove any vestiges of prior exploration work at the two sites before returning them to the state. The Kashagan venture partners have resisted these requests, said the people familiar with the matter, asking not to be named because the information is private. “The Aktoty and Kairan fields were discovered in the early 2000s. No actual development work or transition to production has been carried out during this period,” Kazakhstan’s Energy Ministry said in a statement. “Therefore, Kazakhstan and the consortium are currently coordinating the procedure for returning these fields to the state.”—With assistance from Mitchell Ferman, Shoko Oda, Kathy Chen, Francois de Beaupuy, Alberto Brambilla and David Wethe.Postmedia is committed to maintaining a lively but civil forum for discussion.
