The Norwegian Petroleum Directorate (NPD) reports that Neptune Energy Norge AS, operator of production licence 882, has concluded the drilling of wildcat well 33/6-5 S.

The well was drilled about 10 kilometres northwest of the Snorre field in the northern part of the North Sea and 160 kilometres west of Florø.

The primary exploration target for the well was to prove petroleum in Middle Jurassic reservoir rocks (the Rannoch Formation). The secondary exploration target was to prove petroleum in the Statfjord Group in the Lower Jurassic, depending on oil in the Rannoch Formation.

The well encountered around 90 metres of the Rannoch Formation with sandstone of moderate to good reservoir quality.

In the Upper Jurassic, the well encountered around 30 metres of the Draupne Formation, with 5 metres of intra-Draupne sandstone of poor to moderate reservoir quality.

Well 33/6-5 S was terminated at a shallower level than the planned secondary exploration target in the Statfjord Group.

The well is dry. Data acquisition has been carried out.

This is the fourth exploration well in production licence 882. The licence was awarded in APA 2016.

Well 33/6-5 S was drilled to a vertical depth of 3428 metres and a measured depth of 3488 metres below sea level, and was terminated in the Drake Formation in the Lower Jurassic.

Water depth at the site is 315 metres. The well has been permanently plugged and abandoned.

Well 33/6-5 S was drilled by the Deepsea Yantai drilling rig, which will now drill development wells in production licence 586 in the Norwegian Sea, where Neptune Energy Norge AS is the operator.
