26/06/2015 Tullow Oil Norge AS, operator of production licence 591, is about to complete drilling of wildcat well 6507/11-11.  

The well was drilled about 15 kilometres southeast of the Heidrun platform in the Norwegian Sea.

The primary exploration target for the well was to prove petroleum in Upper Jurassic reservoir rocks (the Rogn formation). The secondary exploration target was to prove petroleum in the Middle Jurassic Garn formation, which is part of the Fangst group.

The well did not encounter reservoir rocks in the Rogn formation. The well encountered about 35 metres of reservoir rocks in the Garn formation, of which about 25 metres were of very good reservoir quality.

The well is dry.

Data acquisition and sampling were carried out.

This is the first exploration well in production licence 591. The licence was awarded in APA 2010.

Well 6507/11-11 was drilled to a vertical depth of 2875 metres below the sea surface and was terminated in the Fangst group in the Middle Jurassic.

Water depth at the site is 270 metres. The well will be permanently plugged and abandoned.

Well 6507/11-11 was drilled by the Leiv Eiriksson drilling facility, which will now proceed to production licence 420 in the North Sea to plug wells 35/9-11 S and 35/9-11 A.
