MOSCOW, Jan 23 (Reuters) - Oil production at Kazakhstan's vast Tengiz oil field, one of the world's largest, did not resume after it had been shut down on Monday, Interfax said on Friday, citing Kazakh oil producer Tengizchevroil (TCO), which is led by Chevron CVX.N.
Oil production at the Tengiz oil field could be halted for another 7-10 days, three industry sources told Reuters earlier.
