Chevron’s Tengiz oilfield in Kazakhstan has recovered to roughly 60 % of its peak production, bringing output to about 560,000 barrels per day. The field’s peak reached 932,000 barrels per day in May 2025, and Chevron’s long‑term target is 1 million barrels per day.
The recovery follows a turbine‑transformer fire that broke out on January 18 2026, which forced a temporary shutdown of the power station that supplies the field. The incident halted production for several days and prompted a rapid response from Chevron’s operations team to restore power and restart drilling and production equipment.
Prior to the fire, Tengiz was producing 870,000 barrels per day in January 2025 and had peaked at 932,000 barrels per day in May 2025. The current 60 % recovery therefore represents a significant rebound from the production dip caused by the fire, and it aligns with Chevron’s 260,000‑barrel‑per‑day growth plan for 2026.
The rapid turnaround supports Chevron’s upstream output mix and helps the company meet its guidance for Q1 2026, which had been adjusted for maintenance and downtime at Tengiz. By returning to near‑peak output ahead of schedule, Chevron mitigates the financial impact of the outage and reinforces its strategy of maintaining high‑breakeven assets.
"Tengiz’s swift recovery demonstrates our operational resilience and underpins our 2026 volume growth targets," said Mike Wirth, Chevron’s CEO. The statement highlights the company’s confidence in its ability to manage large‑scale incidents and keep its flagship asset on track.
The incident had previously raised concerns about Kazakhstan’s oil supply chain, but the field’s rebound signals that Chevron’s risk management and contingency planning are effective, reducing uncertainty for investors and stakeholders.
