Energy firm GDF Suez has unveiled an oil discovery at the 22 / 16-6 well on the Dalziel structure in the UK Central North Sea.

The well flowed at a rate of more than 8,000 barrels of oil equivalent per day. It will now be side-tracked to appraise the extent of the discovery.

The Transocean Galaxy II jack-up rig was used to drill the well. Block 22 / 16 is part of GDF Suez’s operated licence P.1799.

GDF Suez E&P UK managing director Ruud Zoon said: "This is another encouraging discovery by GDF Suez following on from a successful exploration campaign in 2014.

"It demonstrates a continuing commitment by GDF Suez to an active exploration, appraisal and development drilling programme on the UK Continental Shelf."

GDF Suez is also operator of the Cygnus field and the UK licence operator of the Orca field in the southern North Sea. The company also operates several exploration licences in the area.

Cygnus is located in the southern North Sea, 150km off the coast of Lincolnshire. It has gross proved and probable reserves of about 18 billion cubic metres. First gas is anticipated in late 2015.
