Well history
WRITTEN BY THE NORWEGIAN OFFSHORE DIRECTORATE
General
Well 16/5-6 was drilled to test the Rome Central prospect on the southeast part of the Utsira High in the North Sea. The primary objective was to test the presence of and hydrocarbon potential in the Late Jurassic Intra Draupne sandstone. The secondary target was to test the hydrocarbon potential in the underlying preserved wedge of Triassic or Paleozoic sediments.
Operations and results
Wildcat well 16/5-6 was spudded with the semi-submersible installation Borgland Dolphin on 22 June 2016 and drilled to TD at 2350 m in the Triassic Skagerrak Formation. No significant problem was encountered in the operations. The well was drilled with Seawater and sweeps down to 702 m, with Innovert NS oil based mud from 702 m to 2134 m, and with KCl/GEM water based mud from 2134 m to TD.
Well 16/5-6 failed to prove the presence Late Jurassic Intra Draupne Formation sandstone sequence prognosed to overlie a Triassic section. Instead, the well drilled directly from a thin (6 m) Late Jurassic Draupne shale and 109 m into a tight sandstone sequence of Triassic or possibly Paleozoic age. No shows or indications of moveable hydrocarbons were observed in the well.
No cores were cut. No wire line logs were run. No fluid sample was taken.
The well was permanently abandoned on 10 July 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.
