The Chevron-led venture Tengizchevroil has begun restoring production at the Tengiz oil field in Kazakhstan, the country's Energy Ministry announced.

According to the ministry, production operations at Tengiz have resumed, with the first well, GZU-52, successfully opened at 3:35 a.m. local time, The Caspian Post reports.

Process units at the PBF facility have been launched and are operating normally.

A total of five wells have already been commissioned. Tengizchevroil’s technical teams are now preparing to bring the next group metering unit, GZU-53, online. Production volumes will be increased gradually as system parameters stabilize and process safety is ensured.

Officials said the situation remains under constant monitoring, with strict compliance with industrial safety standards a continuing priority.
