Neptune drills dry well near Snorre field

Neptune Energy Norge AS has plugged a North Sea well in production license 882. The well is dry.

Well 33/6-5 S, the fourth exploration well in the license, was drilled about 10 km northwest of Snorre field by the Deepsea Yantai drilling rig in the northern part of the North Sea to a vertical depth of 3,428 m and a measured depth of 3,488 m below sea level (OGJ Online, Aug. 19, 2021). It was terminated in the Drake formation in the Lower Jurassic. Water depth at the site is 315 m.

The primary exploration target 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 m of the Rannoch formation with sandstone of moderate to good reservoir quality.

In the Upper Jurassic, the well encountered around 30 m of the Draupne formation, with 5 m 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.

Data acquisition has been carried out.

The rig will now drill development wells in production license 586 in the Norwegian Sea for operator Neptune.
