Well history
WRITTEN BY THE NORWEGIAN OFFSHORE DIRECTORATE
General
Well 6204/11-3 was drilled to test the Schweinsteiger prospect in the northern part of the Måløy Slope in the northern North Sea. The primary objective was to prove producible hydrocarbons in the Cretaceous Åsgard Formation.
Operations and results
Wildcat well 6204/11-3 was spudded with the semi-submersible installation Borgland Dolphin on 14 September 2020 and drilled to TD at 1321 m, 50 m into Basement. A 9 7/8" shallow gas pilot hole was drilled from 307 to 631 m. Shallow gas was observed at 331 m. Visible gas bubbles were seen that lead to pumping of kill mud. The well was killed with no visible gas observed by the ROV. Operations proceeded without significant problems. The well was drilled with seawater and hi-vis pills down to 307 m and with Glydril mud from 307 m to TD.
The target Åsgard Formation sandstone was not encountered. Instead, the well encountered 140 m of undifferentiated Cromer Knoll Group siltstone with sandstone and limestone stringers from 1084 - 1224 m. The well also penetrated a 47 m section of undifferentiated Jurassic of interbedded sandstone, siltstone, and claystone from 1224 to 1271 m. The basement also consisted of sandstone. All sandstones were water bearing with no oil shows.
No cores were cut. No fluid sample was taken.
The well was permanently abandoned on 14 September 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.
