Well history
WRITTEN BY THE NORWEGIAN OFFSHORE DIRECTORATE
General
Exploration well 34/2-1 is located a northwestern part of the Tampen Spur area. It was intended to be the first well to test the reflections below the Base Cretaceous (Kimmeridgian) Unconformity on a seismically defined, northerly trending west-northwest dipping fault block. The well was located near the apex of the structure at the Base Cretaceous level, but down-dip with respect to deeper stratigraphy. Primary targets were the Middle Jurassic Brent Formation and the Early Jurassic/Triassic Statfjord Formation. Secondary targets were possible Early Tertiary and Late Jurassic sandstones. Planned TD was 4300 m Sub Sea.
Operations and results
Wildcat well 34/2-1 was spudded with the semi-submersible installation Byford Dolphin on 29 December 1979. Due to problems with the guide line and instability of the temporary guide base three unsuccessful spuds were made before a successful spud was made on 23 January 1980. The well was drilled to TD at 807 meters in the Tertiary. Being unable to latch the BOP onto the 20-inch wellhead, 34/2-1 was permanently abandoned on 23 February 1980 as a junked well. A total of 68 days was spent on the well.
Testing
No drill stem test was performed.

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.
