Well history
WRITTEN BY THE NORWEGIAN OFFSHORE DIRECTORATE
General
Well 25/10-15 S was drilled to test the Rovarkula Prospect, about 19 km north of the Ivar Aasen field and 6 km north of the Hanz Discovery. Structurally, the Rovarkula prospect is situated on the eastern margin of the Gudrun Terrace. The primary objective was to investigate the resource potential in Late Jurassic Intra Draupne sandstones. Secondary objective was to evaluate the resource potential in the Middle Jurassic Hugin sandstones.
Operations and results
Wildcat well 25/10-15 S was spudded with the jack-up installation Mærsk Interceptor on 14 July 2016 and drilled to TD at 2696 m (2684 m TVD) m in the Permian Rotliegend Group. No significant problem was encountered in the operations. The well was drilled with seawater down to 450 m and with Versatec oil based mud from 450 m to TD.
The well encountered approximately 37 metres of Intra Draupne Sandstone with moderate to poor reservoir properties. The Hugin and Skagerrak Formations were 11 and 65 metres respectively, with reservoir properties representative of nearby wells. All reservoir intervals were proven to be entirely water bearing.
No shows above fluorescence caused by the oil based mud were observed in the well.
No cores were cut. No fluid sample was taken.
The well was permanently abandoned on 2 August 2016 as a dry well.
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.
