Statoil drills dry well east of North Sea' s Jotun field
STAVANGER, Norway -- Statoil Petroleum is in the process of concluding the drilling of wildcat well 25/9-4.
The well was drilled about 25 km east of the Jotun field in the central part of the North Sea, and about 138 km 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 m thick Hugin formation, of which approx. 15 m had relatively good reservoir properties, and a Sleipner formation of about 31 m 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 2,397 m below sea level, and was terminated in the Sleipner formation in the Middle Jurassic. The water depth is 116 m. 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.
