SINGAPORE, Jan 21 (Reuters): Chevron (CVX.N), plans to close a deal to sell its oil refining and distribution assets in Singapore in the first quarter of the year as it engages in a final round of talks with Japanese refiner Eneos and Glencore, four sources with knowledge of the matter said.

The assets for sale include Chevron's stake in a refinery, a terminal and retail stations in Singapore, the sources said. Chevron is also looking to include retail stations in Cambodia and Malaysia in the deal, one of the sources said.

Together, these assets are valued at $1 billion or more, two of the sources added.

The sale is part of the U.S. major's plans to divest refining and storage assets in Asia as it restructures globally to streamline operations and reduce costs.

Chevron, Eneos and Glencore declined to comment.

Reuters has reported on the sale of the refinery stake previously but details of the other assets being offered are not publicly known.

Morgan Stanley, which has been appointed by Chevron to handle the sale of the SRC refinery stake and other assets in Asia, declined to comment.

Boston Consulting Group is advising Eneos on this deal, two sources said. BCG declined to comment on the matter.
