06/01/2015 Lundin Norway AS, operator of production licence 625, is about to complete drilling of wildcat well 25/10-12 S. The well is dry.
The well was drilled about 20 kilometres northwest of the 16/2-6 Johan Sverdrup discovery in the central part of the North Sea and 180 kilometres west of Stavanger.
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 to Lower Jurassic reservoir rocks (Hugin and Sleipner formations, as well as the Statfjord group).
The well encountered about five metres of “intra Draupne sandstone” of poor reservoir quality. Two sandstone intervals of about 40 and 50 metres were encountered in the Hugin formation. The reservoir quality is very good at the top and good in the lowest interval. The Sleipner formation was not encountered, while the Statfjord group has a few thin sandstone layers. The Draupne and Hugin formations have traces of oil. The well is classified as dry.
Extensive data acquisition and sampling have been carried out.
This is the first exploration well in production licence 625, which was awarded in APA 2011.
Well 25/10-12 S was drilled to respective vertical and measured depths of 2540 and 2567 metres below the sea surface, and was terminated in the Triassic (presumably the Smith Bank formation). The well will be permanently plugged and abandoned. Water depth is 116 metres.
The well was drilled by the Island Innovator drilling facility, which will now drill wildcat well 26/10-1 in production licence 674 BS, where Lundin Norway AS is the operator.
