Well history
WRITTEN BY THE NORWEGIAN OFFSHORE DIRECTORATE
General
Well 25/2-19 S is an appraisal of the 25/2-10 S Frigg GammaDelta discovery. Well 25/2-19 S was drilled in the south-west end of the Bjørgvin Arch in the North Sea, east of the 25/2-10 S GammaDelta. The primary objective was to evaluate the hydrocarbon potential in the Frigg Formation and to obtain fluid samples.
Operations and results
A 9 7/8" pilot hole was drilled down to 1102 m. No shallow gas or waterflow was observed.
Appraisal well 25/2-19 S was spudded with the jack-up installation Mærsk Interceptor on 27 August 2017 and drilled to TD at 2380 m in the Paleocene Sele Formation. Operations proceeded without significant problems. The well was drilled with seawater and hi-vis pills down to 1102 m and with EMS 4600 oil-based mud from 1102 m to TD.
Top Frigg Formation was encountered at 2100 m (1989.4 m TVD), with oil down to the OWC at 2114.5 m (2003 m TVD). The well was drilled with no returns to surface down to 1102 m. Below 1102 m there were no shows detected above the oil-based mud, apart from a questionable show in the oil-bearing Frigg reservoir. Oil mobility in the Frigg reservoir was confirmed by sampling.
No cores were cut. Twenty two samples were acquired with the MDT tool: three oil samples at 2101.2 m, five oil samples at 2104.3 m, three oil samples at 2107.2 m, five oil with traces of formation water samples at 2111.5 m, one water with traces of formation oil at 2113.0 m, and five water samples at 2114.4 m. Interval Pressure Transient Tests were conducted at all these depths except 2101.2 m due to probe being plugged at the end of the station.

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.
