The Norwegian Petroleum Directorate (NPD) had announced a minor oil discovery made by Lundin Energy Norway and its partners near the Solveig field in the North Sea, following the drilling of the wildcat well 16/4-13 S.
Located in the production licence 359, the wildcat well 16/4-13 S was drilled about 15km south of the Edvard Grieg field in the central part of the North Sea and 190km west of Stavanger.
Lundin operates the production licence 359 with 65% interest while OMV (Norge) and Wintershall Dea Norge hold 20% and 15% stakes respectively.
The aim of drilling the well was to prove the presence of petroleum in reservoir rocks from the Triassic to Paleozoic Age.
Using the West Bollsta semi-submersible drilling rig, the well was drilled to measured and vertical depths of 2,422m and 2,325m respectively, below sea level.
Upon drilling, the well encountered a 10m oil column in conglomerate sandstone in reservoir rocks, of which 7m reported moderate to poor reservoir quality.
The entire reservoir comprises conglomeratic sandstones with a thickness of about 380m.
According to preliminary estimates, the discovery holds between 500,000 and 1.4 million standard cubic metres (Sm³) of recoverable oil equivalent.
The well 16/4-13 S, which was terminated in Paleozoic rocks, represent the sixth exploration well to be drilled in the licence.
The licence partners plan to assess the discovery considering a possible tie-in to the Solveig field while the well is planned to be permanently plugged and abandoned.
The West Bollsta drilling facility is scheduled to begin drilling activities at the production well 16/4-BA-1H on the Solveig field in production licence 359 in the North Sea.
