Wildcat well 6406/6-7 S is the first well drilled by the licensees in production licence 1119, but the fifth within the licence area as a whole.

The well was drilled by the Deepsea Atlantic rig, around 170 kilometres northwest of Kristiansund.
Preliminary estimates indicate that the discovery contains 3-7 million standard cubic metres (Sm3) of recoverable oil equivalent (o.e.), which corresponds to 19-44 million barrels of recoverable o.e.

The llicensees are considering a tie-back solution, where the discovery is connected to existing and planned infrastructure in the area.

Geological information

The primary exploration target for the well was to prove petroleum in Middle Jurassic reservoir rocks in the Garn Formation. The secondary exploration target was to prove petroleum in Middle Jurassic reservoir rocks in the Ile Formation.

Well 6406/6-7 S encountered a 46-metre gas/condensate column in a sandstone reservoir with good reservoir properties. The total thickness of the Garn Formation was 85 metres. The petroleum/water contact was encountered 3780 metres below sea level.

The Ile Formation was 86 metres thick in total, and was aquiferous with poor reservoir quality.

Extensive data acquisition and sampling have been carried out.

The well was drilled to a vertical depth of 4024 metres below sea level, and was terminated in the Ror Formation in the Lower Jurassic.

Water depth at the site is 256 metres. The well will be permanently plugged and abandoned.
