Det norske oljeselskap has completed the drilling of wildcat well 25/10-15 S, in the North Sea. The well is dry.

The well was drilled in the central part of the North Sea, about six kilometres north of the Hanz discovery and 200 kilometres northwest of Stavanger.

The well is located in production license 626, named Rovarkula, where Det norske is the operator with 50% interest and its partners are Tullow Oil Norge with 30%, MOL Norge with 10% and Fortis Petroleum Norway with 10%.

The primary exploration target for the well was to prove petroleum in Upper Jurassic reservoir rocks (intra Draupne sandstone). The secondary exploration target was to prove petroleum in Middle Jurassic reservoir rocks (Hugin formation).

The well encountered a 36.5-metre thick sandstone in the Upper Jurassic with moderate to poor reservoir quality and an 11-metre thick Middle Jurassic sandstone with good to moderate reservoir quality. The well also encountered a 65-metre thick Skagerrak formation with moderate reservoir quality. The well is dry. Data acquisition has been carried out.

Well 25/10-15 S was drilled to a measured depth of 2696 metres (MD RT) and a vertical depth of 2629 metres below the sea surface. The well was terminated in basement of unknown age.

This is the first exploration well in production license 626. The license was awarded in APA 2011.

Water depth is 117 metres. The well will now be permanently plugged and abandoned.

Well 25/10-15 S was drilled by the Mærsk Interceptor jack-up drilling rig, which will now proceed to drill wildcat well 25/2-18 S in production license 442, where Det norske is the operator.
