NCS: Gjøkåsen Deep is dry

NPD released the results for wildcat well 7132/2-2/Gjøkåsen Deep prospect, with Equinor Energy AS as the main operator in production license 857, and the results are not positive. The Gjøkåsen prospect is located on the Signalhorn Dome at the border of the Tiddlybanken Basin in the southeastern part of the Norwegian Barents Sea.

The well was targeting the Snadd, Kobbe and Havert formation as primary focus and the lower Havert formation, as secondary. The final TD of well 7132/2-2 is 3496 m below the sea surface and was terminated in the Røye formation from the Late Permian Age. Water depth at the site is 304 m.


The well encountered 25 m of sandstone reservoir with moderate to good quality in the Snadd formation (Carnian Age), 17 m of sandstone reservoir with poor to moderate quality in the Kobbe formation and 26 m of sandstone reservoir with poor quality in the upper Havert formation. Sandstone reservoir was also encountered in the Klappmyss formation (Early Triassic Age) in a thickness of 17 m with poor quality.

In the lower Havert formation, the well encountered an interval of approx. 110 m of sandstones with very poor reservoir quality. High measurements of formation gas led to an extension of the well. The objective of the extension was to evaluate the potential presence of source rock and underlying reservoir rocks in the Lower Triassic and Upper Permian (the Ørret and Røye formation). No reservoir rocks were encountered in this interval. The well will be permanently plugged and abandoned.

Gjøkåsen Deep prospect as Gjøkåsen Shallow prospect have been proven not to bear hydrocarbons.
