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...

Kashagan Operator Faces July 20 Deadline to Pay $4.9 Billion Environmental Fine

Kazakhstan says it will begin compulsory collection proceedings against the North Caspian Operating Company (NCOC), operator of the giant Kashagan oil field, if it does not pay a 2.3 trillion tenge ($4.9 billion) environmental fine by July 20. The deadline follows a domestic court ruling that has entered into legal force, even as the project’s foreign shareholders pursue international arbitration over the penalty. Deputy Minister of Justice Daniyel Vaisov announced the deadline on July 14. “Foreign companies currently have an obligation to pay 2.3 trillion tenge. If they fail to pay the fine by July 20, the Republic of Kazakhstan will proceed in accordance with the law, including enforcement proceedings and compulsory collection measures,” Vaisov said. However, in a statement to The Times of Central Asia, NCOC said a tribunal in parallel UNCITRAL arbitration proceedings had issued a restraining order prohibiting Kazakhstan from taking any measures to enforce the fine while the arbitration is pending. The company said the UNCITRAL proceedings had been initiated by Kazakhstan itself. NCOC and the contracting companies said they reject both the fine and the allegations underlying it and are contesting them through the UNCITRAL proceedings as well as the ICSID arbitration. They called on Kazakhstan to comply with the restraining order. The dispute stems from a 2022 inspection of Kashagan’s onshore processing facilities in the Atyrau Region. Environmental authorities said the operator had exceeded its permitted sulfur-storage limits, and the Ministry of Ecology and Natural Resources imposed the 2.3 trillion-tenge penalty in 2023. NCOC said it had obtained and maintained all required permits and had always conducted its sulfur management in full compliance with the law. The case has passed through several rounds of domestic litigation. On August 1, 2025, the Administrative Chamber of Astana City Court annulled the original penalty order because of procedural violations, without ruling on the substance of the environmental allegations. The ministry subsequently corrected the procedural defects and reissued the penalty later that month. An Astana court left the reissued fine in force on April 8, 2026. Vaisov said on July 14 that the ruling had entered into legal force. NCOC brings together Kazakhstan’s state-owned KazMunayGas and six foreign partners: Shell, TotalEnergies, Eni, ExxonMobil, CNPC, and Inpex. NCOC and the project’s six foreign shareholders have initiated treaty arbitration through the Washington-based International Centre for Settlement of Investment Disputes (ICSID), arguing that Kazakhstan’s conduct breaches protections owed to investors. Vaisov said the parties were finalizing the composition of the ICSID tribunal, which is expected to be completed by the end of July. “We believe the Republic’s actions regarding the alleged sulfur-storage permit violations are inconsistent with its obligations under international investment treaties, including its obligation to provide fair and equitable treatment to investors,” NCOC said. The Kazakh authorities maintain that the sulfur was stored in breach of environmental rules. The mechanics of compulsory collection may prove difficult. Nurlan Zhumagulov, executive director of the Energy Monitor Foundation, said that NCOC acts as the project’s operator while each shareholder markets its own...
