Kazakhstan slows oil output after drone strikes on export port

Output has been reduced in particular at the Chevron-led CVX.N Tengiz oilfield, Kazakhstan's largest, two industry sources said.

Output there had more than halved, one source said, to around 406,000 barrels per day on Wednesday from 925,000 bpd on average this month.

The country's overall oil and gas condensate output on Wednesday fell to 1.63 million bpd from July's average of 2.07 million, the source said.

Chevron did not immediately reply to a Reuters request for comment.

More than 1,500 km (940 miles) long, the CPC pipeline runs from Kazakhstan's Tengiz oilfield in the west of the country via Russia to the port of Novorossiysk on Russia’s Black Sea coast.
