7/4-3

23/05/2013 Lundin Norway AS, operator of production licence 495, is about to complete drilling on wildcat well 7/4-3. The well was drilled about 24 km north of the Brynhild field in the southern part of the North Sea.

The primary exploration target for the well was to prove petroleum in Upper Triassic reservoir rocks (the Skagerrak formation). The secondary exploration target was to prove petroleum in chalk in the Ekofisk and Tor formations (Palaeocene and Upper Cretaceous). Reservoir rocks were not encountered in the Triassic, while the reservoir in the chalk was as expected. The well is dry.

Data acquisition and sampling have been carried out. This is the first exploration well in production licence 495. The licence was awarded in APA 2008.  

The well was drilled to a vertical depth of 2957 metres below the sea surface and was terminated in the Smith Bank formation in the Triassic. Water depth is 82 metres. The well will be permanently plugged and abandoned.

Well 7/4-3 was drilled by the Maersk Guardian drilling facility, which will now proceed to production licence 148 in the North Sea to drill production wells on the Brynhild field where Lundin Norway AS is the operator.
