Well history
WRITTEN BY THE NORWEGIAN OFFSHORE DIRECTORATE
General
Valhall well 2/8-16 S was drilled from the Valhall platform in the Southern North Sea. The objective was to evaluate the Mjød structure in the Tor Formation on the eastern flank of the Valhall Field.
Operations and results
Wildcat well 2/8-16 S was drilled in combination with development well bores on the Valhall Field, using a down hole splitter system (DHS) marketed by Baker Oil Tools and Kværner National. The 2/8-16 S well was spudded from the "Splitter Housing" installed at ca 1409 m and proceeded without too much trouble to 1662 m where mud losses were seen. At 1927 m the losses had become severe, and this had not been seen on Valhall before. Examination of a seismic dip-map at approximately 1700 m TVD RKB showed that the well track had crossed a major fault at about the same depth as the losses became severe. The seismic image indicated the zone could be about 75 m wide. After curing the mud loss problems drilling continued to 3139 m, where a wiper trip was made back to 2100 m. On running back in hole an obstruction was hit at 2133 m. After working past this obstruction it became evident that the hole had collapsed. At this time it was decided to abandon the well track in favour of drilling an oil production well 2/8-A20 B. Well 2/8-16 S was drilled using an oil-based mud.
As the reservoir section was not reached, no log evaluation was done and the well was classified as a junk well.
No cores were cut and no wire line fluid samples taken.
The well was permanently abandoned on 14 March as a junk well.
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.
