RWE Dea Norge AS finishes drilling North Sea wildcat well

Oilfield Technology,

RWE Dea Norge AS, operator of production licence 420, is in the process of concluding the drilling of wildcat well 35/9-12 S.

The well was drilled approximately 20 km southwest of the Gjøa field in the North Sea and around 80 km southwest of Florø.

Dry well

The objective of the well was to prove petroleum in Upper Jurassic reservoir rocks (Intra Heather formation sandstone). Well 35/9-12 S encountered reservoir rocks in two sandstone layers in the Heather formation, both of good quality and with traces of petroleum. The well will be classified as dry.

Plugged and abandoned

Extensive data acquisition and sampling have been carried out. This is the fourth exploration well in production licence 420. The licence was awarded in APA 2006.

Well 35/9-12 S was drilled to vertical and measured depths of 3423 and 3531 metres below sea level, respectively and was terminated in the Rannock formation in the Middle Jurassic. Water depth at the site is 358 m. The well will be permanently plugged and abandoned.

Well 35/9-12 S was drilled by the Leiv Eiriksson drilling facility, which will now drill wildcat well 6406/6-4 in production licence 510 in the Norwegian Sea, where Maersk Oil Norway AS is the operator.
