Spirit Energy drills dry well near North Sea Ivar Aasen field

Spirit Energy Norway AS, operator of production license 780 will plug well 16/1-33 S in the central part of the North Sea (OGJ Online, June 22, 2020). The well is dry.

The well was drilled the by the Leiv Eiriksson semisubmersible drilling rig about 5 km north of Ivar Aasen field and about 200 km west of Stavanger to respective vertical and measured depths of 3,042 and 3,158 m subsea. It was terminated in the Skagerrak formation in the Upper Triassic. Water depth at the site is 116 m.

The objective of the exploration well, the first in the license, was to prove petroleum in reservoir rocks in the Middle Jurassic (Sleipner formation) and the Upper Triassic (Skagerrak formation).

The well encountered the Sleipner formation with a thickness of about 205 m, with 85 m of aquiferous sandstone layers of moderate to very good reservoir quality. The Skagerrak formation came in at a thickness of about 75 m, with a total of 15 m of aquiferous sandstone layers with moderate to good reservoir properties.

The well was not formation-tested, but data acquisition was carried out.

The Leiv Eiriksson rig will now proceed to drill wildcat well 6507/4-1 in production license 1009 in the southern part of the Norwegian Sea, where ConocoPhillips Skandinavia AS is operator (OGJ Online, Aug. 3, 2020).
