Dana Petroleum has announced the successful appraisal of the Fulla gas condensate field through the drilling of a second Fulla well 30/11-7A, offshore Norway.

The well, which is a side-track of the initial discovery well, 30/11-7, is located only 10km north-east of the Frigg field in the North Sea.

In February 2009 the first Fulla well made a discovery in the lower part of the Brent group in well 30/11-7, located on the same prospect, close to the abandoned Lille Frigg field.

The second well encountered gas in reservoir rocks belonging to the upper part of the Brent group (Tarbert formation).

As planned the discovery was not tested but extensive data collection and sampling has been carried out. Proven volumes for the two wells are estimated at between 60 and 105 million barrels of oil equivalent.

The well was drilled in 111m of water to a vertical depth of 4,118m below the sea surface in the Etive formation of the Brent group, using the Transocean Leader semi-submersible rig.

The Fulla discovery is thought likely to be commercial and a development by tie-back to nearby infrastructure is being considered.
