Britannia-NorthSea

ConocoPhillips and co-venturer Chevron have received approval from the UK Department of Energy and Climate Change (DECC) to develop the Enochdhu discovery, in the UK central North Sea.

Enochdhu discovery, which is said to be the fourth field to be developed in the Greater Britannia area, is expected to produce at an initial peak rate of more than 10,000 barrels of oil per day in late 2014.

Other fields in the area include Britannia, Brodgar and Callanish, which altogether have produced around 600mm boe to date.

Enochdhu, which is operated jointly by ConocoPhillips and Chevron, is a black oil Palaeocene reservoir in 140m (459ft) of water in block 21/5a of license P.103 in the central North Sea.

The discovery is located 18km south-west of the Britannia platform and eight kilometres south-east of the Callanish subsea manifold.

"Other fields in the area include Britannia, Brodgar and Callanish, which altogether have produced around 600mm boe to date."

As part of the development a two-slot production manifold will be tied back to the Callanish subsea manifold through a multiphase production pipeline and gas lift pipeline, as well as electro-hydraulic controls umbilical.

Close to the Callanish manifold, a tie-in manifold will be stationed and the manifolds, pipelines and umbilical will be incorporated into a subsea bundle.

Gas that is processed on the Britannia platform will be transported to the Southern Area Gas Evacuation (SAGE) terminal at St Fergus, in eastern Scotland, through a dedicated pipeline.

Liquids will be transported through the Forties Pipeline System to the Kinneil Terminal. ConocoPhillips and Chevron each own 50% interest in Enochdhu exploration well.
