Tengizchevroil (TCO) restored oil output on its Tengiz oil field in Kazakhstan to normal levels after a fall during unscheduled maintenance early in March, a company representative told Reuters in an email on Wednesday.

Chevron-led said all oil production trains on the oil field were now online and output was back to normal, it said.

Daily oil output on Tengiz was down by 11% from March 1-6 owing to unscheduled maintenance on one of the production trains.

Oil output on Tengiz was up to 645,000 barrels per day (bpd) on March 10, from 563,000 bpd from March 1-6, according to two sources familiar with the daily oil production data.

Chevron holds a 50% stake in TCO, Exxon Mobil XOM.N owns 25%, Kazakh state firm Kazmunaigas KMGZ.KZ holds 20% and 5% belongs to Russia’s Lukoil LKOH.MM.
