Wellbore history
General
Well 30/11-12 A is a geological sidetrack to 30/11-12 S, the Askja SE discovery well on the Eastern flank of the Fensal Sub-Basin in the North Sea. The well is situated two kilometres south of the 30/11-9 A (Askja East) discovery, and about 35 km southwest of the Oseberg Sør facility. The objective of 30/11-12 A was to clarify the hydrocarbon-water contact downflank on the Askja SE structure.
Operations and results
Appraisal well 30/11-12 A was kicked off at 1228 m in 30/11-12 S on 4 May 2016. It was drilled with the semi-submersible installation Songa Delta to TD at 4173 m (3638 m TVD) m in the Middle Jurassic Tarbert Formation. No significant problem was encountered in the operations. The well was drilled with XP-07 oil based mud from kick-off to TD.
Top Tarbert Formation came in at 3961 m (3429 m TVD), 40 m deep to prognosis. The well, including the Tarbert Formation, was dry without shows. Valid pressure points in sands in the Tarbert Formation all lie on a common water gradient.
No cores were cut. MDT water samples were taken at 3975.9 m.
The well was permanently abandoned on 20 May 2016 as a dry appraisal 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.
