RWE Dea Norge is to plug and abandon its wildcat well 35/9-12 S on the Atlas prospect in production license (PL) 420 in the North Sea after it was classified dry.
The well was drilled about 20km southwest of the Gjøa field in the North Sea and about 80km southwest of Florø.
The objective of the well was to prove petroleum in Upper Jurassic reservoir rocks (Intra Heather formation sandstone), said the Norwegian Petroleum Directorate. 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.
Extensive data acquisition and sampling have been carried out. This is the fourth exploration well in PL 420. The license was awarded in APA 2006.
Well 35/9-12 S was drilled to vertical and measured depths of 3423 and 3531 meters below sea level, respectively and was terminated in the Rannock formation in the Middle Jurassic. Water depth at the site is 358m. 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 PL 510 in the Norwegian Sea, where Maersk Oil Norway is the operator.
