Japanese firm Itochu is planning to sell its stakes in two North Sea developments, according to a news report.
Reuters said the company is aiming to fetch up to £185million through the sale.
It includes Itochu’s 25% stake in the Western Isles cluster and Hudson field east of Shetland.
The news agency cited “banking sources” in its report without naming any.
Korean-owned Dana Petroleum owns the assets.
The Western Isles field cluster yielded 45,000 barrels of oil per day in April.
Reuters said the sale is being run by Scotiabank.
Itochu has been approached for comment.
