wlbHistory: 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.

Testing

No drill stem test was performed
