Dana today announces the successful drilling and testing of well 21/19-12z to appraise the Grouse oil field. Grouse is located in Block 21/19 within the Greater Kittiwake Area (“GKA”) in the UK Central North Sea.

Grouse was first discovered in 1981 by the 21/19-1a well. Subsequent work justified drilling a horizontal well to target better quality, thicker reservoir sands to the southwest of the discovery well. This well was spudded by the Noble TVL semi-submersible rig in late August and has now been successfully completed. Stabilised flow rates in excess of the pre-drill expectations were achieved. The well flowed at rates of over 10,600 boepd, through a 32/64” choke, with a tubing head pressure of around 2,700 psi, but this flow rate was limited by the throughput capacity of the test equipment.

The well will be suspended for use as a future producer and Grouse will be developed as a subsea tieback to the Kittiwake platform utilising the Goosander production riser which was installed in 2006. Planning for a fast track development will commence immediately with first oil targeted for first quarter 2009.

Commenting on the news, Tom Cross, Dana’s Chief Executive said:

“The very positive Grouse appraisal well results are another important step forward in the Greater Kittiwake Area, building on the development of the Gadwall field, the high performing Goosander field and the work done in the Kittiwake and Mallard fields, since this area was acquired from Shell and Esso in 2003. With the imminent start-up of the new Kittiwake-Forties pipeline, the drilling of the Morgan exploration well in early 2008 and the further potential production from additional satellite fields, the producing life of this area will be significantly extended.”
