Well history
WRITTEN BY THE NORWEGIAN OFFSHORE DIRECTORATE
General
Well 25/11-26 was drilled on the Utsira High in the North Sea ca 1 km northwest of the Grane Field. The main objective of well 25/11-26 was to prove commercial hydrocarbons in the Eocene Odin sandstone Member of the Nanna prospect, and determine whether this reservoir was in communication with the Grane Field. The secondary objective was to validate the seismic AVO anomaly of the Nanna prospect, and thereby provide means of de-risking other Odin sandstone prospects within the licence. A third objective was to prove commercial hydrocarbons in Late Jurassic Intra Draupne Formation Sandstones of the Leviathan prospect.
Operations and results
Well 25/11-26 was spudded with the semi-submersible installation Ocean Vanguard on 16 January 2013 and drilled to TD at 2235 m in the Early Jurassic Statfjord Group. No significant problem was encountered in the operations. The well was drilled with seawater and hi-vis sweeps down to 1099 m and with XP-07 oil based mud from 1099 m to TD.
No hydrocarbons were shown in any of the prospects. The gas readings were very low throughout the whole well. There was no sign of the Odin sandstone in the Balder Formation resulting in no oil or gas shows. The Draupne Formation consisted of claystone with minor limestone stringers and only a thin stringer of tight sandstone, no hydrocarbons were seen.
No cores were cut. No fluid samples were taken.
The well was permanently abandoned on 17 February 2013 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.
