KIEV, Oct. 1 – Russian oil major Lukoil on Thursday threatened to shut down its Ukrainian oil refinery after the country’s oil shipper suggested switching pipeline routes to enable massive imports of Caspian Sea crude.

UkrTransNafta said it wanted to use Odessa-Kremenchuk section to deliver Caspian crude to UkrTatNafta, Ukraine’s largest oil refinery, suggesting that Lukoil may deliver its crude to its Odessa refinery via Brody-Odessa pipeline.
