Well history
WRITTEN BY THE NORWEGIAN OFFSHORE DIRECTORATE
General
Well 25/6-6 S was drilled to test the Pabow prospect in the south-western part of the Stord Basin, about 7 km east of the 25/6-1 discovery in in the North Sea. The primary exploration target for the well was to prove gas in reservoir rocks from the Early Jurassic (the Statfjord group). The secondary exploration target was to examine reservoir rocks from the Middle Jurassic (the Hugin formation).
Operations and results
Wildcat well 25/6-6 S was spudded with the semi-submersible installation Transocean Spitsbergen on 28 March 2019 and drilled to TD at 3546 m in the Middle Triassic Hegre Group. Drilling proceeded without significant problems. Ca 3 days NPT occurred during wire line operations due to stuck tool. The well was drilled with seawater and hi-vis pills down to 793 m, with KCl/GEM/polymer mud from 793 m to 993 m, and with XP-07 oil-based mud from 993 m to TD.
Well 25/6-6 S encountered the Statfjord group with a thickness of about 330 metres, of which 80 metres with reservoir rocks of moderate to good reservoir quality. The Hugin formation has a thickness of about 45 metres, of which 30 metres with reservoir rocks of good quality. Good pressure data indicate almost hydrostatic pressure from Seabed to TD. The well is dry. There were no shows throughout the well.
No cores were cut. MDT water samples were taken at 2963.2 m and 2628.9 m
The well was permanently abandoned on 22 April as a dry well without shows.
Testing
No drill stem test was performed.

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.
