Well history
WRITTEN BY THE NORWEGIAN OFFSHORE DIRECTORATE
General
Well 30/11-11 A is a geological sidetrack to well 30/11-11 S on the East flank of the Fensal Sub-basin in the North Sea. It was drilled to test the Viti prospect in a fault block separate from and to the east of the 30/11-11 S Madam Felle oil discovery. The primary objective was to test the hydrocarbon potential in the Middle Jurassic Tarbert Formation.
Operations and results
Wildcat well 30/11-11 A Viti was kicked off by milling a window inside the 13 3/8" casing in well 30/11-11 S at a depth of 1092 m in the Hordaland Group claystone. The well was drilled to a total depth of 4016 m (3362.8 m TVD) in the Tarbert Formation. No significant problem was encountered in the operations. The well was drilled with XP07 oil-based mud from kick-off to TD.
Top Brent Group, Tarbert Formation came in at 3796 m (3168.1 m TVD). All Brent Group reservoirs were water wet. No shows were seen in the well.
Due to no discovery, no cores and no fluid samples were taken.
The well was permanently abandoned on 7 April 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.
