Exxon Mobil is considering selling all of the stakes it holds in oil and gas fields off the Norwegian coast, a company spokesman told business daily Dagens Naeringsliv. Two years ago the U.S. major – the world’s largest oil company – sold its operated assets in the area. But it has retained stakes in more than 20 other fields, including Equinor-operated Snorre and Shell-operated Ormen Lange. The Norwegian paper quoted an unnamed industry expert as saying the assets could be worth $3-4 billion. In 2017, Exxon Mobil’s net production from fields off Norway was around 170,000 barrels of oil equivalent per day. Exxon Mobil’s spokesman in Norway was not immediately available for comment.
