Well history
WRITTEN BY THE NORWEGIAN OFFSHORE DIRECTORATE
General
Well 30/9-25 was drilled on the Cerberus prospect about six kilometres south of the Oseberg Sør facility in the North Sea. The primary objective was to appraise the hydrocarbon potential in the upper Tarbert Formation and Intra-Heather Formation sandstones. Secondary objective was to test the presence and hydrocarbon potential of Intra-Draupne Formation sandstone
Operations and results
Appraisal well 30/9-25 was spudded with the semi-submersible installation Ocean Vanguard on 10 August 2013 and drilled to TD at 3220 m in the Middle Jurassic Ness Formation. No shallow gas was encountered in the well and the operations proceeded without significant problems. The well was drilled with seawater and hi-vis sweeps down to 445 m, with KCl/polymer/glycol mud from 445 m to 1552 m and with XP-07 oil based mud from 1552 m to TD.
Reservoir sandstones were encountered in Heather, Tarbert and Ness Formations, but they were dry. No Intra-Draupne Formation sandstone was present. The only hydrocarbon indications were shows on the core +/- 2910 m in Intra-Heather Formation sandstone and +/- 2913 m in the upper Tarbert Formation.
One 54 m core was cut from 2897 m in the Heather Formation to 2951 m in the upper Tarbert Formation with 100% recovery. The core - log depth shift was found to be +4.5 m. No pressure or fluid samples were taken due to hole instability during the MDT run.
The well was permanently abandoned on 20 September 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.
