The Norwegian Petroleum Directorate (NPD) reports that Aker BP ASA, operator of production licence 814, has completed the drilling of wildcat well 15/6-15.

The well was drilled about 15 kilometres north-east of the Gina Krog field and 225 kilometres west of Stavanger. The well is dry.

The primary exploration target for well 15/6-15 was to prove petroleum in reservoir rocks from the Middle Jurassic Age (the Hugin and Sleipner formation). The secondary exploration target was to examine reservoir rocks from the Triassic Age (the Skagerrak formation).

Well 15/6-15 encountered the Sleipner formation with a thickness of about 125 metres, of which 40 metres were reservoir rocks of good to moderate reservoir quality. The Skagerrak formation was encountered with a thickness of about 140 metres, of which 15 metres were reservoir rocks with poor reservoir quality. The well is characterised as dry.

Data acquisition and sampling have been carried out.

This is the first exploration well in production licence 814, which was awarded in APA 2015.

The well was drilled to a vertical depth of 3761 metres below the sea surface and was terminated in the Skagerrak formation.

Water depth at the site is 109 metres. The well will now be permanently plugged and abandoned.

Well 15/6-15 was drilled by the Deepsea Stavanger drilling rig, which will now proceed to production licence 777 in the central part of the North Sea to continue drilling wildcat well 15/6-16 S, where Aker BP is the operator.
