ConocoPhillips’ upstream involvement in the UK began in September 1964 when acreage was awarded to the company in the first UK licensing round. In 1968, the Viking gas field was discovered and first gas was produced in 1972. Since then the UK portfolio has grown to include additional operated assets, as well as interests in non-operated fields. In 2011, ConocoPhillips produced 132,000 barrels of oil equivalent per day in the UK.
Upstream in the UK, ConocoPhillips is operator of a number of fields in the Central North Sea including Britannia, BritSats and J-Block.
In the Southern North Sea, ConocoPhillips has various interests in producing gas fields in the Rotliegendes and Carboniferous areas including: the Lincolnshire Offshore Gas Gathering System (LOGGS), the V-fields (North Valiant, South Valiant, Vanguard and Vulcan), Vampire - Valkyrie, Viscount, Kx, the Saturn Unit Area (Saturn, Mimas and Tethys, Hyperion and Atlas), the Jupiter Area gas fields (Ganymede, Sinope, Callisto, Europa and NW Bell), the Viking Transportation System (VTS), Victor, the Viking group of reservoirs and the Vixen and Victoria subsea satellites, the Caister Murdoch System (CMS), Murdoch, Caister, Boulton, CMS III (Hawksley, McAdam, Murdoch K, Bouton H and Watt), Munro, Kelvin and the Harrison/Katy field.
In the East Irish Sea, ConocoPhillips’ offshore assets include Millom, Dalton, Calder, Darwen and Crossens. The company also has interests in the Clair field in the West of Shetland.
In the UK, the company is owner or operator of three Onshore Terminals - the Theddlethorpe Gas Terminal in Lincolnshire, the Teesside Oil Terminal at Seal Sands in Middlesborough and the Rivers Gas Terminal at Barrow-in-Furness. It also holds a non-operated interest in the Interconnector pipeline (a 145-mile, 40-inch diameter bidirectional subsea pipeline running from Bacton in the UK to a reception terminal at Zeebrugge in Belguim).
