ABERDEEN – July 28, 2008 – ConocoPhillips (U.K.) Limited, Operator, announces first production from the Callanish and Brodgar fields “Britannia Satellites” development, co-owned with Chevron North Sea Limited.

Callanish, an oil field with four wells and Brodgar, a gas condensate field with two wells are tied back through subsea manifolds to the Britannia Bridge-linked platform (BLP) and controlled remotely from the Britannia platform.

The Company expects the combined peak net production from the two fields to be in excess of 65,000 barrels oil equivalent per day (BOED). Archie Kennedy, managing director of ConocoPhillips (U.K.) Limited, said: “The Britannia Satellites development is a major addition to our UK production portfolio and will contribute to ConocoPhillips’ presence in the United Kingdom Continental Shelf.“

Notes to the Editor:
Callanish:
Licensees for Callanish: ConocoPhillips (U.K.) Limited, Operator, 83.5% and Chevron North Sea Limited, 16.5%.

The Callanish field is located approximately 25 kilometres from the Britannia platform and straddles two blocks, 15/29b and 21/4aN, in the central North Sea. It comprises two accumulations; a main field area, which was discovered in 1999 and an outlier to the west separated by a structural saddle. Callanish is tied-back to the BLP via a 25 kilometre, 12-inch pipeline and consists of four subsea horizontal wells, three in the main field and one in an area referred to as the Outlier. Gas lift and methanol is supplied from Britannia via 6-inch and 3-inch pipelines respectively.

Partial separation of Callanish fluids is carried out on the BLP before being transferred via the bridge to Britannia. Following additional processing on Britannia, liquids are co-mingled with Britannia condensate and exported via the Forties pipeline system to BP’s Kinneil terminal at Grangemouth. Gas is co-mingled and sent via SAGE – the Scottish Area Gas Evacuation facilities at St Fergus

Brodgar:
Licensees for Brodgar: ConocoPhillips (U.K.) Limited, Operator, 75% and Chevron North Sea Limited, 25%.

The Brodgar field is a gas condensate accumulation located approximately 41 kilometres south-west of the Britannia platform and situated in block 21/3a in the central North Sea. The field was discovered in 1985. The Brodgar gas condensate field comprises two subsea horizontal development wells.

Brodgar is tied back to the BLP via a 41-kilometre, 12-inch pipeline. Continuous mono-ethylene glycol (MEG) injection (to prevent hydrates formation) is supplied via a 3-inch pipeline. A 3-inch methanol pipeline has also been laid to Brodgar.

The fluids are partially separated on the BLP before being transferred to the Britannia platform where gas is co-mingled and exported via SAGE – the Scottish Area Gas Evacuation facilities at St Fergus. Liquids are also co-mingled with Britannia condensate and exported via the Forties pipeline system to BP’s Kinneil terminal at Grangemouth.

Britannia Field:
The Britannia gas/condensate field development is located 210 kilometres north-east of Aberdeen and is one of the largest and most significant ever undertaken in the United Kingdom. Under an agreement unique to the UK, Chevron and ConocoPhillips established a separate company, Britannia Operator Limited (BOL), to act as Operator of the field. Britannia came on stream in 1998 and plays a key role in meeting the UK’s need for primary energy from indigenous sources.
