RockRose Energy, the independent oil and gas company, completed the acquisition of the UK unit of Marathon Oil, an American petroleum and natural gas exploration and production company, for $140m. The deal gives RockRose 37-40% operated interests in the Greater Brae Area, a 28% stake in the BP-operated Foinaven field, and 47% of Foinaven East. "This acquisition marks a major step-change in the Group's reserves and production profile. Given the quality of these assets the Board's view is this is a good opportunity to make the transition to the role of operator. We look forward to welcoming Marathon Oil UK employees, who have an excellent track record operating in the North Sea, to the RockRose team at closing," Andrew Austin, RockRose Executive Chairman.
