- Oil production at the Chevron CVX.N-led Tengiz field, Kazakhstan's largest, fell sharply on May 26 due to an accident, two industry sources told Reuters on Friday, while output is currently being restored.

The sources, who spoke on condition of anonymity due to the sensitivity of the situation, said output at Tengiz is currently at between 5,000 metric tons and 10,000 tons, comparing to the usual level of 125,000 tons.

Supplies to the Caspian Pipeline Consortium, the main conduit for Kazakhstan's oil exports, have been reduced in line with the production fall, the sources said.

The sources said a gradual restoration of Tengiz oil production is expected within a week or so.

Chevron declined immediate comment.
