The government of Kazakhstan has initiated an asset freeze against the North Caspian Operating Company (NCOC), the consortium responsible for developing the Kashagan oil field in the Caspian Sea. This move, which targets the company's property and transport assets, marks a significant escalation in an ongoing dispute regarding a massive environmental fine.
The legal conflict stems from a 2023 decision by a local court, which ordered the consortium to pay 2.3 trillion tenge, approximately $4.9 billion, citing improper sulfur storage. The fine, which the foreign consortium members have rejected as baseless, is currently tied to broader arbitration proceedings. While Kazakhstan’s state-owned Kazmunaigas, which holds a 16.88 percent stake in NCOC, reportedly offered to pay its share of the penalty, the international partners—Shell, Eni, TotalEnergies, and ExxonMobil, each holding 16.81 percent, alongside China’s CNPC (8.33 percent) and Japan’s Inpex (7.65 percent)—have refused to pay.
On July 21, the Ministry of Justice disclosed the decision to freeze assets and informed NCOC managing director Giancarlo Ruiu that he could face administrative and criminal liability for non-compliance. While the specific nature of the seized property remains unclear, the government maintains that its actions are necessary to enforce environmental and public interest protections. A UNCITRAL tribunal had previously declined a request from Kazakhstan to lift restraining measures on the enforcement of the fine while arbitration remains pending. However, the Ministry of Justice stated that an interim order from a commercial arbitration proceeding does not limit the state’s sovereign rights. This stance is bolstered by Kazakhstan’s new Constitution, hastily approved via referendum on March 15 and in force since July 1, which dictates that domestic laws take precedence over international obligations.
The 2022 fine arose after NCOC allegedly breached sulfur storage permits. The accumulation of sulfur, a toxic byproduct of oil extraction, occurred during a period when a temporary export ban prevented the company from selling the material to Chinese importers. Analysts have suggested that such environmental fines are frequently utilized by the Kazakh government as political instruments to pressure foreign operators into renegotiating contracts. In 2011, Kazakhstan’s government threatened an environmental fine against Karachaganak, a major gas and condensate field. The consortium sold off a 10 percent stake to Kazmunaigas and the fine disappeared. Seven years later, the foreign consortium operating Karachaganak agreed to pay Kazakhstan a $1.1 billion compensation. According to the International Consortium of Investigative Journalists, Kazakhstan’s 2023 arbitral claim stated that NCOC “currently receives 98 percent of all post-Priority Payment revenue from oil production.” President Kassym-Jomart Tokayev has consistently pushed for improved terms for the production sharing agreements governing the nation's largest oil fields, including Tengiz and Karachaganak, which serve as critical contributors to the national budget, with new contract terms expected by 2026 for the 4 major projects.
