Kazakhstan’s $5 Billion Kashagan Fine Moves Into New Legal Phase
Kazakhstan has escalated its dispute with the foreign investors behind the Kashagan oil field, warning the consortium’s managing director that he could face administrative and criminal liability over its failure to pay an environmental fine of nearly $5 billion. The warning to Giancarlo Ruiu, managing director of North Caspian Operating Company, was reported by Reuters, which cited two sources and a document it had reviewed. NCOC’s shareholders include Eni, ExxonMobil, Shell, and TotalEnergies, each with a 16.81% stake; Kazakhstan’s state-owned KazMunayGas, with 16.88%; CNPC, with 8.33%; and Inpex, with 7.56%. The dispute began after the Department of Ecology for the Atyrau Region inspected the consortium’s production facilities in 2022 and identified about ten alleged violations. Inspectors said that by November 1, 2022, more than 1.7 million metric tons of sulfur had accumulated at a storage site within the Bolashak oil and gas processing complex. NCOC’s permit allowed it to store no more than 730,000 tons. According to the environmental authorities, the operator had exceeded the permitted limit by more than twofold. In early 2023, the regional environmental department issued a notification seeking 2.356 trillion tenge in penalties, equivalent to about $5.4 billion at the exchange rate at the time. NCOC rejected the allegations and maintained that its sulfur-handling operations complied with Kazakh law and the permits issued for the project. The proceedings continued for more than three years. In August 2025, a court set aside the original notification because of procedural deficiencies in the way it had been issued. The ruling did not dismiss the environmental allegations themselves. The authorities subsequently issued a new notification, allowing the case to proceed. After further domestic proceedings, the Atyrau Regional Court upheld the penalty on June 19, allowing the ruling to enter into force. It later emerged that members of the consortium had been aware of the risk posed by the growing sulfur stockpiles for years. In 2017, Eni warned that the project was heading towards exceeding the permitted storage capacity. By late 2020, NCOC had also cautioned that Kazakhstan’s new Environmental Code, adopted the following year, would increase the risk of substantial penalties. According to internal documents reported by Bloomberg, Eni executives proposed processing more of the sulfur for sale on international markets. ExxonMobil, TotalEnergies, CNPC, and Inpex were not planning comparable measures at the time, while KazMunayGas had yet to settle on a position. On July 14, Kazakhstan’s Ministry of Justice said the domestic court ruling had entered into force and gave NCOC until July 20 to pay voluntarily. The ministry said compulsory enforcement proceedings could begin if the consortium failed to meet the deadline. NCOC did not pay by July 20. The Justice Ministry subsequently warned Ruiu of possible liability for non-compliance, marking a further escalation in a dispute that had already moved beyond the original question of sulfur storage. The consortium continued to deny wrongdoing and maintained that the penalty could not be enforced while international arbitration proceedings were under way. Its foreign shareholders are separately challenging the fine...
