ABERDEEN, UK – ConocoPhillips (U.K.) and Chevron North Sea have approval from Britain’s government to develop the Enochdhu discovery in the UK central North Sea.

First production is expected to flow in late 2014, at a peak rate of more than 10,000 boe/d.

Enochdhu is a black oil Palaeocene reservoir in 140 m (459 ft) water depth in block 21/5a of license P.103 in the central North Sea. It is 18 km (11 mi) southwest of theBritannia platform and 8 km (4.97 mi) southeast of the Callanish subsea manifold, operated jointly by ConocoPhillips and Chevron.

This will be the fourth field development in the Greater Britannia Area afterBritannia, Brodgar, and Callanish. To date the fields have produced around 600 MMboe.

Development will involve a two-slot production manifold tied back to the Callanish subsea manifold via a multi-phase production pipeline, gas lift pipeline, and electro-hydraulic controls umbilical.

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

Gas processed on the Britannia platform is transported via a dedicated pipeline to the Southern Area Gas Evacuation (SAGE) terminal at St. Fergus, eastern Scotland, while liquids head to the Kinneil Terminal via the Forties Pipeline System.
