Norwegian oil company Det Norske Oljeselskap ASA (DETNOR.OS) said Monday it has completed drilling and testing appraisal well 34/6-3 S and the wildcat sidetrack well 34/6-3 A on the Garantiana discovery in the Norwegian North Sea.

The updated resource range in production licence PL554 is estimated at 40 million-90 million barrels of oil equivalent (boe).

Data analysis and studies have been launched to confirm the resource basis and to evaluate possible development scenarios.

The appraisal well 34/6-3 S encountered a gross oil column of 120 metres in the Cook formation with good reservoir quality. The Statfjord formation was water bearing.

The separate sidetrack exploration well 34/6-3 A on the "Akkar" prospect encountered a 12 meter net oil column in the Cook formation and was terminated in the Statfjord formation which was water bearing. Estimated recoverable resources proved by the well is about 3 million boe.

Both wells are permanently plugged and abandoned.

Det norske holds 10% working interest in PL554. The operator is Total E&P Norge AS with 40% and the other partners are Spike Exploration with 30% and Svenska Petroleum with 20%.
