According to Chevron, Tengizchevroil experienced a “minor operational disruption” at one of its production facilities. The company said oil output is now being restored. The company emphasized that ensuring safe and reliable operations remains its top priority and declined to comment further on specific production or commercial details.

Kazakh Energy Ministry said the incident resulted in a temporary decline in oil production at the Tengiz field, one of the country’s largest energy assets.

“The company is currently taking the necessary operational measures, and the production process at the field is in the recovery stage,” reads the statement.

Authorities stressed that no risks to personnel, residents or the environment have been identified. The ministry added that it is closely monitoring the situation as production gradually returns to normal levels.

Operated by Tengizchevroil, the Tengiz field in West Kazakhstan is one of the world’s deepest and largest oil fields and a key contributor to the country’s crude oil output and export revenues.
