Well history
WRITTEN BY THE NORWEGIAN OFFSHORE DIRECTORATE
General
Well 7/1-1 was drilled on the J{ren High in the southern part of the North Sea, ca 8 km east of the UK border line.
Operations and results
Wildcat well 7/1-1 was spudded with the semi-submersible installation Sedco 135 F on 3 July 1971 and drilled to TD at 2808 m in the Triassic Skagerrak Formation. There were indications of shallow gas at 472 m, otherwise no significant problems were reported from the drilling operations.
The well penetrated Quaternary and Tertiary sediments with no significant sand development down to a depth of 2224 m where Cretaceous Chalk of the Tor Formation was encountered. The Cretaceous section continued down to 2661 m where the sandy Triassic Skagerrak Formation was encountered. The well was dry and no shows were reported from the well other than those originating from diesel added to the mud.
Two cores were cut, one from 2243.3 to 2261.6 m in the Tor Formation and the other from 2451.2 to 2468.9 m in the Hod Formation. No wire line fluid samples were taken.
The well was permanently abandoned on 5 August 1971 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.
