Well history
WRITTEN BY THE NORWEGIAN OFFSHORE DIRECTORATE
General
Well 25/1-11 was drilled on the Storklakken prospect between the Heimdal- and Frigg Fields in the North Sea. The objective was to drill a top hole down to setting of the 13 3/8" casing, after which the well would be suspended due to planned repairs of the rig Aker Barents. The exploration objective would be fulfilled in a later re-entry.
Operations and results
Well 25/1-11 was spudded with the semi-submersible installation Aker Barents on 4 January 2010. A 9 7/8" Pilot hole was drilled to 1178 m from AUX ram, before opening up to 17 ½" hole. No indications of shallow gas were seen during the pilot hole. TD was set at 1178 m in Early Oligocene to Miocene sediments of the Hordaland Group. After running and cementing 13 3/8" casing, the well was suspended, due to a planned DAT (Direct Acting Tensioners) Cylinder repair on Aker Barents. The well was drilled with seawater/bentonite/CMC to TD.
No cores were cut and no wire line fluid samples were taken.
The well was suspended on 12 January 2010.
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.
