12/01/2018 Lundin Norway AS, operator of production licence 533, is in the process of concluding the drilling of wildcat well 7219/12-3 S.
The well was drilled about 34 kilometres northwest of the 7220/11-1 (Alta) discovery well, and about 2.5 kilometres southwest of the 7219/12-1 (Filicudi) discovery well.
The primary exploration target for wildcat well 7219/12-3 S was to investigate the reservoir potential and prove petroleum in two reservoir levels from the Late Jurassic and Early Jurassic/Middle Jurassic Age (the Hekkingen formation and the Stø/Nordmela formations).
The secondary exploration target was to investigate the reservoir potential in two reservoir levels from the Early Cretaceous and Late Triassic/Early Jurassic Age (the Kolje and Tubåen formation).
Well 7219/12-3 S did not encounter reservoir rocks in the Hekkingen formation. In the Stø formation, the well encountered water-bearing sandstone layers totalling about 100 metres with moderate to good reservoir quality. In the Nordmela formation, the well encountered water-bearing sandstone layers totalling about 90 metres, with moderate reservoir quality. In the Kolje formation, a thin water-bearing sandstone layer with poor reservoir quality was encountered, and in the Tubåen formation, the well encountered water-bearing sandstone layers totalling about 40 metres with moderate reservoir quality. The well is dry.
Data acquisition and sampling have been carried out.
This is the sixth exploration well in production licence 533. The licence was awarded in the 20th licensing round in 2009.
The well was drilled to a vertical depth of 2682 metres below the sea surface, and was terminated in the Fruholmen formation from the Late Triassic Age.
Water depth at the site is 313 metres. The well will now be permanently plugged and abandoned.
Well 7219/12-3 S was drilled by the Leiv Eiriksson drilling facility, which will now permanently plug well 7219/12-1 in the same production licence.
