Well history
WRITTEN BY THE NORWEGIAN OFFSHORE DIRECTORATE
General
Well 16/1-33 S was drilled to test the Sørvesten prospect on the Gudrun Terrace west of the Utsira High in the North Sea. The primary objective was to test the hydrocarbon potential in the Middle Jurassic Sleipner Formation and the Triassic Skagerrak Formation.
Operations and results
Wildcat well 16/1-33 S was spudded with the semi-submersible installation Leiv Eiriksson on 10 July 2020 by tagging seabed with the 9 7/8" pilot hole BHA. The shallow gas pilot hole was drilled to 555 m, 5 m deeper than the planned setting depth for the 20" surface casing. No shallow gas was encountered. Drilling proceeded to final TD at 3158 m (3066.8 m TVD) m in the Late Triassic Skagerrak Formation. Operations proceeded without significant problems. The well was drilled with seawater and hi-vis pills down to 553 m and with Rheguard oil-based mud from 553 m to TD.
No hydrocarbons were encountered in any formation. Seven pressure points were taken with Stethoscope LWD tool on the way out of hole, proving a hydrostatic pressure slightly depleted compared to the regional pressure regime. Apart from some fluorescence in traces of sand in the Draupne and Heather formations there were no shows in the well.
No cores were cut, no wireline runs were made, and no fluid sample was taken.
The well was permanently abandoned on 6 August 2020 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.
