Well history
WRITTEN BY THE NORWEGIAN OFFSHORE DIRECTORATE
General
Well 34/10-12 was drilled on Tampen Spur in the North Sea close to the western side of the Gullfaks Fault Block. The primary objective of the well was to test sandstones of Middle Jurassic age. Secondary objectives were sandstones of Early Jurassic age.
Operations and results
Wildcat well 34/10-12 was spudded with the semi-submersible installation Neptuno Nordraug on 16 July 1981 and drilled to TD at 2800 m in the Early Jurassic Statfjord Group. The well was drilled with seawater and prehydrated Gel pills down to 298 m and with gel/lignosulphonate mud from 298 m to TD.
The sandstones of both Middle and Early Jurassic age were water saturated. Shows were recorded on cuttings from claystones, limestone and occasional thin sandstones from 1260 m in the Hordaland Group to 1657 m in the Balder Formation. The Jurassic had only trace fluorescence in sandstone cuttings at 2094 to 2110 m in the Ness Formation, otherwise no trace of hydrocarbons were seen.
One core was cut from 2037 m to 2042.7 m in the Ness Formation. No wire line fluid samples were taken.
The well was permanently abandoned on 12 September as a dry 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.
