Royal Dutch Shell is considering the sale of some of its North Sea operations following its £35 billion takeover of rival oil and gas producer BG Group.

Shell has commited to raise up to $30 billion from asset sales around the world following the expensive deal for BG Group.

News reports over the weekend claimed potential buyers of Shell’s North Sea asset buyers could include the Neptune oil and gas fund run by Sam Laidlaw, former chief executive of Centrica.

“A review of all assets, including those in the North Sea, is under way as part of our commitment to the $30 billion asset sale,” a Shell spokesman told the Financial Times.
