04/08/2016 Det norske oljeselskap AS, operator of production licence 626, has completed the drilling of wildcat well 25/10-15 S. 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 primary exploration target for the well was to prove petroleum in Upper Jurassic reservoir rocks (intra Draupne formation sandstone). The secondary exploration target was to prove petroleum in Middle Jurassic reservoir rocks (Hugin formation).
The well encountered 23-metre thick sandstones in the Draupne formation with moderate to good reservoir quality and a 11-metre thick sandstone in the Hugin formation with good reservoir quality. The well also encountered 23-metre thick sandstones in the Skagerrak formation with moderate reservoir quality. In addition 77-metre with sandstones were encountered in the Heimdal formation with very good reservoir properties. The well is dry. Data acquisition has been carried out.
Well 25/10-15 S was drilled to a measured depth of 2696 metres and a vertical depth of 2629 metres below the sea surface. The well was terminated in basement.
This is the first exploration well in production licence 626. The licence 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 drilling facility, which will now proceed to drill wildcat well 25/2-18 S in production licence 442, where Det norske oljeselskapet AS is the operator.
