BP PLC 13 February 2003 February 13, 2003 BP TO SELL SOUTHERN NORTH SEA GAS PACKAGE TO PERENCO BP announced today that it has agreed to sell a package of its UK Southern North Sea gas production assets to Perenco UK Limited for $162 million in a cash transaction. The sale has an effective date of January 1, 2003 and is subject to UK regulatory consent and other approvals. The sale includes BP's share in 14 operated gas fields including Indefatigable, East Leman, Davy, Trent, Tyne, Pickerill and Waveney, together with associated pipelines and onshore processing facilities including the Bacton terminal. Perenco has indicated a desire to operate these assets, subject to government and licence partner approvals. BP's share of combined proved gas reserves for these fields is approximately 274 billion cubic feet and BP's share of production is around 150 million cubic feet per day or about 26,000 barrels a day oil equivalent. BP's overall current production from the UK North Sea is approximately 750,000 barrels a day. BP retains a significant business in the Southern North Sea, operating nine gas fields, associated pipelines and the onshore terminals at Dimlington and Easington. BP also owns substantial interests in the Conoco-operated Viking, Valiant and Vulcan fields, and the Shell-operated Sean field. The BP share of production from these fields amounts to some 380 million cubic feet per day or about 66,000 barrels a day oil equivalent. BP said that the sale would improve returns on its upstream portfolio by reducing operating costs and freeing up capital for investment in other projects offering better profit margins. BP said: 'We are pleased to have reached this agreement with Perenco. The deal brings another new entrant into the UKCS and this can only benefit the province as it matures. We expect that the deal will be completed by 4Q 2003 and will provide all necessary assistance to Perenco to ensure a smooth transfer of the assets.'
