25/9-4

21/02/2014 Statoil Petroleum AS, operator of production licence 628, is in the process of concluding the drilling of wildcat well 25/9-4.

The well was drilled about 25 kilometres east of the Jotun field in the central part of the North Sea, and about 138 kilometres west of Haugesund.

The objective of the well was to prove petroleum in Middle Jurassic reservoir rocks (the Hugin and Sleipner formations). The well encountered an approx. 19-metre thick Hugin formation, of which approx. 15 metres had relatively good reservoir properties, and a Sleipner formation of about 31 metres with relatively poor reservoir properties. The well is dry.

Data acquisition and sampling have been carried out. The well is the first exploration well in production licence 628, which was awarded in APA 2011.

The well was drilled to a vertical depth of 2397 metres below sea level, and was terminated in the Sleipner formation in the Middle Jurassic. The water depth is 116 metres. The well will be permanently plugged and abandoned.

Well 25/9-4 was drilled by the Ocean Vanguard drilling facility, which will now proceed to the 16/2-6 Johan Sverdrup oil discovery in production licence 265 in the central part of the North Sea to drill appraisal well 16/2-19, where Statoil is the operator.
