Japan’s top oil refiner ‍Eneos is leading rival bidders for Chevron’s stake in a Singapore ‍refinery, with a deal nearing completion, though potential delays remain, Bloomberg News reported on Wednesday, citing people familiar with the matter.

Reuters could not immediately verify the ‍report. Eneos and Chevron did not immediately respond to Reuters’ request for comment.

Reuters reported in September that Chevron’s Singapore refinery, the second-largest in the region, is valued at about $1 billion. Global commodities traders Vitol and Glencore were expected to submit formal bids for a 50% stake in the facility.
