The well was drilled about 1 km west of the Solveig field in the North Sea and 190 km west of Stavanger.
The well’s primary exploration target was to prove petroleum in sandstones in the Ty Formation from the Palaeocene. The secondary exploration target was to prove petroleum in porous dolomite in the Zechstein Group from the Permian Age.
The well encountered 58 m of sandstone in the Ty Formation with good to very good reservoir quality.
In the secondary exploration target, the well encountered 12 m of dolomitic rocks in the Zechstein Group with poor to moderate reservoir quality.
Well 16/4-12 also encountered two intervals of sandstone from an undefined age between the Cretaceous and Triassic. The upper interval has a thickness of 16 m with moderate to good reservoir quality. The lower interval has a thickness of 15 m with good to very good reservoir quality.
The well is dry. Data acquisition has been carried out.
This is the first exploration well in production licence 981, which was awarded in APA 2018.
Well 16/4-12 was drilled to a vertical depth of 2141 m below sea level and was terminated in the Zechstein Group from the Permian Age.
Water depth at the site is 100 m. The well will be permanently plugged and abandoned.
Well 16/4-12 was drilled by the Deepsea Stavanger drilling facility, which is now moving on to drill wildcat well 17/8-1 in production licence 976 in the North Sea, where Lundin Energy Norway AS is the operator.
