Well history
WRITTEN BY THE NORWEGIAN OFFSHORE DIRECTORATE
General
Well 34/10-22 was drilled on the Gullfaks Field to test for possible shallow gas around the planned position of the Gullfaks A platform.
Operations and results
Well 34/10-22 was spudded with the semi-submersible installation on 25 October 1984 and drilled to TD at 579 m in Pliocene sediments in the Nordland Group. No significant problem was encountered in the operations. The well was drilled with water based mud
Pliocene sediments were encountered at 292 m, based on the logs. Four Pliocene sand layers were penetrated, and the two shallowest, at 310-315 m and 393-396 m, were gas bearing.
Eight core runs were attempted and a total of 22.2 m core was recovered in four cores. Wire line logging at TD was performed. The bottom hole temperature 3 hours after circulation was 23.3 deg C. No fluid samples were taken.
The well was permanently abandoned on 5 November 1984.
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.
