Well history
WRITTEN BY THE NORWEGIAN OFFSHORE DIRECTORATE
General
Well 25/12-25 was drilled to test the Jerv prospect on the northern end of the Maureen Terrace in the North Sea, close to the UK border. The primary objective was to find hydrocarbons in the Paleocene Ty Formation.
Operations and results
A 9 7/8" pilot hole was drilled to section TD at 476 m and no shallow gas or over-pressured water was observed.
Wildcat well 25/12-25 was spudded with the semi-submersible installation COSL Innovator on 18 February 2021 and drilled to TD at 2820 m in the Paleocene Våle Formation. Operations proceeded without significant problems. The well was drilled with seawater and hi-vis pills down to 476 m, and with Aquadril water-based mud from 476 m to TD.
The Ty Formation was penetrated from 2765.5 to 2808 m and contained gas-condensate all through to top Våle Formation. Approximately 30 meters of Ty was sandstone of good reservoir quality. The gas-water contact was not encountered. Oil shows were not observed outside of the Ty Formation. Pressure data collected with TesTrak showed the reservoir to be highly depleted due to production.
Two cores were cut in succession from 2780 to 2811.5 m in the lower sandstone in the Ty Formation and into the Våle Formation. No fluid sample was taken.
The well was permanently abandoned on 26 March 2021 as a gas-condensate discovery.
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.
