Statoil drills dry well near North Sea's Oseberg Sør field

STAVANGER -- Statoil, operator of production licence 104, is in the process of completing the drilling of wildcat well 30/9-25. The well has been drilled about 6 km south of the Oseberg Sør facility, and about 130 km west of Bergen.

The primary exploration target for the well was to prove petroleum in Middle Jurassic reservoir rocks (the Tarbert formation). The secondary exploration target was to prove petroleum in Upper Jurassic reservoir rocks (the Draupne and Heather formation).

Traces of petroleum were encountered in the Tarbert, Heather and Draupne formations.  The well is classified as dry.

Extensive data acquisition and sampling have been carried out. This is the 26th exploration well in production license 104. The license was awarded in the 9th Licensing Round in 1985.

The well was drilled to a vertical depth of 3,220 m below the sea surface and was terminated in the Ness formation in the Middle Jurassic. Water depth at the site is 100 m. The well will now be permanently plugged and abandoned.

Well 30/9-25 was drilled by the Ocean Vanguard drilling facility, which will now proceed to production license 272 in the northern North Sea to drill wildcat well 30/11-9 S, where Statoil is the operator.
