Wintershall Norge said Thursday that its wildcat well 35/12-5 S drilled dry in the Norwegian North Sea.

The well was drilled in Wintershall operated production licence 378,  about 9 miles southwest of the Gjøa field in the North Sea and 49 miles southwest of Florø, the Norwegian Petrolatum Directorate (NPD) said.

The purpose of the well was to prove petroleum in reservoir rocks from the Upper Jurassic, specifically within the Heather, Sognefjord and Fensfjord formations.

Well 35/12-5 S encountered about 32 feet of sandstone in the Heather formation, 114 feet of sandstone in the Sognefjord formation and 104 feet of sandstone in the Fensfjord formation, all with “good reservoir quality.”

The well also encountered 29 feet of sandstone with “poor reservoir quality in the Etive formation,” the NPD said.

Well 35/12-5 S was drilled to a vertical depth of 11,053 feet and a measured depth of 11,712 feet below the sea surface and was terminated in the Oseberg formation in the Middle Jurassic.

Water depth at the site is 11,58 feet.

Data acquisition and sampling have been carried out.

The well has been declared dry and will now be permanently plugged and abandoned.

This is the fifth exploration well in production licence 378 since the license was awarded in 2005.

Well 35/12-5 S was drilled by the Transocean Arctic drilling facility, that is now scheduled to drill wildcat well 6406/12-4 S in production licence 586 in the Norwegian Sea, operated by VNG Norge AS.
