Well history
WRITTEN BY THE NORWEGIAN OFFSHORE DIRECTORATE
General
Well 2/6-6 S was drilled to test the Oppdal and Driva prospects the east side of the Mandal High in the North Sea. The primary objectives were to test the oil potential in the Paleocene Oppdal submarine sandstone reservoir (Borr Member), and in the Permian aeolian reservoir (Auk Formation) in the Rotliegend Driva prospect.
Operations and results
A 9 7/8” pilot hole was drilled to 1012 m due to a slight shallow gas warning between 391 m and 494 m. No obvious shallow gas was encountered here, nor below 500 m.
Wildcat well 2/6-6 S was spudded with the jack-up installation Rowan Viking on 13 November 2018 and drilled to TD at 3843 m (3628 m TVD) m in the Permian Rotliegend Group. Severe losses were experienced while drilling at 3670 m. The well was drilled with seawater and sweeps down to 1014 m m and with EMS-4600 oil-based mud from 1014 m to TD.
The Paleocene Borr Member target (Intra-Våle Formation sandstone) was penetrated from 2908 to 2949 m (2864 to 2898 m TVD). It consisted of sandstone with a layer of claystone close to the top. Three LWD stethoscope pressure points showed a water gradient below the claystone and lack of pressure communication across the claystone. The Borr Member was water bearing. The cored section had weak shows in the form of cut fluorescence and a weak residue, but no direct fluorescence.
Three meters of the Kupferschiefer Formation source rock was penetrated from 3677 to 3680 m. Geochemical samples from this unit showed TOC up to 5.8% and a Hydrogen Index of 350 mg HC/g TOC. Vitrinite reflectance and Tmax indicated pre-oil to earliest oil window maturity at this depth.<

About this data
Norwegian Offshore Directorate (Sodir) FactPages, mirrored nightly and used under the Norwegian Licence for Open Government Data (NLOD). Depths are metres along the wellbore from the kelly bushing unless a row gives its own unit; older cores are filed in feet. A zero the Directorate files for an unmeasured pressure, density, or temperature is shown as a dash.
