Well history
WRITTEN BY THE NORWEGIAN OFFSHORE DIRECTORATE
General
The well 2/1-10 was drilled on a prospect located within PL 164, 7.8km Northwest of Gyda Platform. The primary objective was to test the Upper Jurassic Ula Formation, if successfully, to prove a volume of oil that was commercial as a tie back development to the Gyda Platform. A secondary target was a younger Ula Formation interval.
Operations and results
The wildcat well 2/1-10 was spudded on 9 November 1991 with the semi-submersible installation "Ross Isle", and was completed 14 January 1992 in the Triassic Skagerrak Formation. The well was drilled with sea water and hi-vis pills down to 1101 m and with KCl polymer mud from 1101 m to TD. The upper part of the Ula Formation was encountered at 4189.5 m, 50 m deeper than originally predicted. A 133 m thick Ula Formation was encountered instead of the most likely prognosed model of 15 to 30 m thick Ula formation (intra Farsund) sandstone, separated from underlying Ula Sandstone by a 50 to 60 m thick Farsund mudstone. The Ula Formation was cored from 4194 m to 4289.5 m. Fair quality shows was observed in uppermost 5 meter of sandstone only. 2/1-10 was plugged and abandoned as dry well.

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.
