Well history
WRITTEN BY THE NORWEGIAN OFFSHORE DIRECTORATE
General
Well 25/8-14 S was drilled to test the Forseti Jurassic prospect, located East of the Ringhorne Field on the northern part of the Utsira High in the North Sea. The well was planned deviated with a deviation of about 65 degrees to avoid pipes and pipelaying activity at the sea floor.
Operations and results
Wildcat well 25/8-14 S was spudded with the semi-submersible installation Deepsea Trym on 21 August 2003. It was drilled to 2124 m where mud loss and drilling problems occurred. This caused the well to be plugged back and sidetracked at 1230 m in the 8 1/2" hole. The sidetrack 25/8-14 S T2 was drilled to final TD at 2825 m (2145 m TVD) in the Early Jurassic Statfjord Formation. The well was drilled with sea water and hi-vis pills down to 228 m, with sea water and bentonite sweeps from 228 m to 1051 m, and with Versavert oil based mud from 1051 m to TD.
The Statfjord Group was encountered at 2540 m directly underlying Cretaceous chalk. Oil was found in Statfjord sandstone from 2584.1 m to the OWC at 2611.6 m (1957.5 to 1973.5 m TVD). Oil shows were described on SWC's from the oil bearing reservoir, otherwise no shows over the OBM were recorded in the well.
No conventional cores were cut. RCI wire line fluid samples were taken at 2596.8 m.
The well was permanently abandoned on 22 September as an oil 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.
