UK North Sea

We continue to work hard to maximise the value from our existing UK North Sea portfolio, investing in short cycle, high return opportunities to add reserves, improve recovery and extend field life while continuing to generate material free cash flow.

Our UK offshore operated positions include the Greater Britannia Area, J-Area, AELE, Catcher Area and Tolmount Area. We also have material non-operated stakes in numerous long-life assets including Elgin/Franklin, Buzzard, West of Shetland (Clair, Schiehallion and Solan which is operated) and the Beryl Area. Our other UK North Sea interests include East Irish Sea, Galleon, Ravenspurn North and Johnston.
