Lundin Norway AS has plugged exploration well 7121/1-2 S on the Pointer-Setter prospect in PL767, southeast of the Alta-Gohta discovery in the southern Barents Sea. The well is dry.
The well was drilled to a vertical and measured depth of 3,335 m and 3,350 m subsea with the Ocean Rig Leiv Eiriksson semisubmersible drilling rig about 20 km north of Snøhvit field and about 155 km northwest of Hammerfest in 315 m of water. It was terminated in the Stø formation from the Middle Jurassic Age.
The primary exploration target for the well was to examine reservoir properties and prove petroleum in reservoir rocks from the Early Cretaceous Age (the Kolmule and Knurr formation).
The secondary exploration target was to examine the reservoir potential and properties of reservoir rocks from the Middle Jurassic Age (the Stø formation).
The well encountered the Kolmule formation at about 120 m, with aquiferous sandstone layers totaling 45 m, mainly with moderate reservoir quality. The Knurr formation of about 320 m has sandstone layers totaling about 130 m with traces of oil, but with poor reservoir quality.
In the Stø formation, the well encountered a sandstone layer of 20 m with poor reservoir quality.
Extensive data acquisition and sampling have been carried out on the exploration well—the first in the license. The drilling facility will now drill wildcat well 16/1-31 S in production license 338 in the central part of the North Sea, where Lundin Norway AS is the operator.
