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.
