07/03/2012 Maersk Oil Norway AS, operator of production licence 431, is about to complete drilling of wildcat well 6406/3-9. The well is about 7 kilometres southeast of the Kristin field in the Norwegian Sea.
The objective of the well was to prove petroleum in Cretaceous reservoir rocks (the Lysing and Lange formations). The well encountered oil in two zones distributed over several thin sandstone layers in both formations. The sandstone layers were thinner and the reservoir quality poorer than expected in these formations.
The discovery is not considered commercially interesting. Future studies will quantify the volumes and highlight any additional potential.
The well was not formation tested, but data acquisition and sampling have been carried out.
The well is the first exploration well in production licence 431. The licence was awarded in APA 2006. Maersk Oil Norway AS took over operatorship in the licence in 2009.
The well was drilled to a vertical depth of 4 157 metres below the sea surface, and was terminated in shale in the Lange formation. Water depth is 316 metres. The well will now be permanently plugged and abandoned.
Well 6406/3-9 was drilled by Transocean Winner which will now proceed to the Alvheim field in the North Sea to drill production well 24/6-B-5, where Marathon Oil Norge AS is the operator.
