RockRose Energy has completed the previously announced acquisition of Idemitsu Petroleum UK and its assets in the UK North Sea.

As part of the deal RockRose is taking over Idemitsu's stakes in North Sea fields Ross, Blake, Tain, Nelson, Howe, Balmoral, Stirling, Beauly, Burghley, and Galley fields operated by Shell, Premier, and Repsol.

“Following receipt of a letter of comfort from OGA, RockRose Energy plc is pleased to confirm completion of the purchase of Idemitsu Petroleum UK Ltd,” RockRose said on Friday morning.

RockRose in October said the acquisition would be financed out of the existing facilities and cash resources of the company.
