MOSCOW, Sept 20 (Reuters) - Chevron-led Tengizchevroil (TCO), Kazakhstan's Tengiz oilfield operator, plans to divert 200,000 tonnes of oil to Georgia's Batumi port in October via rail to replace volumes lost due to CPC terminal maintenance, two sources familiar with the company's plans said on Tuesday.

The Caspian pipeline Consortium (CPC), the main export route for Kazakhstan's oil, shut two of three loading facilities in its terminal for maintenance, leading to a sharp decrease in loading capacity. (Reporting by Reuters, Editing by Louise Heavens)
