Well history
WRITTEN BY THE NORWEGIAN OFFSHORE DIRECTORATE
General
Well 25/9-4 was drilled to test the Tastaveden prospect on the western flank of the Stord Basin in the North Sea. The primary objective was to prove commercial resources within the Hugin and Sleipner Formations of the Vestland Group.
Operations and results
Wildcat well 25/9-4 was spudded with the semi-submersible installation Ocean Vanguard on 10 January 2014 and drilled to TD at 2419 m in the Middle Jurassic Sleipner Formation. After reaching TD in the 12 1/4" section running of the BOP was delayed for two weeks due to bad weather. In addition, trouble shooting and repairs of the BOP was needed before the BOP could finally be set. The well was drilled with Seawater and hi-vis sweeps down to 1128 m and with XP-07 oil based mud from 1128 m to TD.
The Vestland Group was encountered with top Hugin Formation at 2372 m and top Sleipner Formation at 2391 m. The Vestland Group was dry without shows as was the rest of the sections penetrated by the well. Post-well analyses proved oil-prone but immature source rock in the Draupne and Heather formations, and confirmed a total lack of migrated hydrocarbons in the well.
No cores were cut and no fluid sample was taken.
The well was permanently abandoned on 27 February 2014 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.
