Det norske has discovered gas in license PL 438 where Lundin Norway AS is the operator. Det norske holds a 10 percent share in the license.

Drilling of exploration well 7120/2-3 is about to be concluded. The well is situated approximately 25 kilometers north of the Snøhvit Field, in the southern part of the Barents Sea.

The well´s primary objective was to prove hydrocarbons in reservoir rocks in the Kolmule formation (Chalk) and the Stø formation (Jurassic).

Gas was proven in three separate zones; a 95-meter column in Kolmule, gas in Knurr and gas in Stø. The well has proven gross contingent resources of 2,5 – 8 billion standard cubic meters (Sm3). Potentially there are further prospective gas and oil resources down-dip in the thicker sands of Knurr, and up-dip in northern segments of Stø.

The licensees in PL438 are considering further appraisal drilling to determine its commercial potential.

Exploration well 7120/2-3S is the first well in PL438. The license was awarded in TFO 2006.

The well was drilled to a vertical depth of 2,579 meters below sea level and was Photo_Harald_Pettersen_-_Statoil Transocean Leader 1concluded in the Snadd formation (Triassic).

The sea depth is 312 meters. The well is now being permanently plugged and abandoned.

Well 7120/2-3S was drilled by Transocean Leader, which now will move to PL265 in the Norwegian North Sea to commence drilling of the Aldous Major South exploration well 16/2-8. Det norske holds a 20 percent share in PL265, Statoil ASA is the operator.
