Well history
WRITTEN BY THE NORWEGIAN OFFSHORE DIRECTORATE
General
Well 34/10-28 was drilled on the fourth well drilled on Gullfaks South. It was drilled in the north-eastern part of the Alpha structure, and the primary objectives were to test for hydrocarbons in the Middle Jurassic Brent Group and the Early Jurassic Statfjord Formation. The Early Jurassic Cook Formation, water bearing in the other wells on the Gullfaks South, was a secondary objective.
Operations and results
Appraisal well 34/10-28 was spudded with the semi-submersible installation Dyvi Stena on 2 January 1986. When running the BOP, after having set the 20" casing, the guide posts were damaged and the well was abandoned with TD at 528 m in Pliocene sediments in the Nordland Group. The well was drilled with water based mud.
Top Pliocene was encountered at 290 m. Shallow gas was found in a sand at 332 - 339 m. Otherwise the drilled section contained clay and only minor sand stringers.
No cores were cut and no fluid samples were taken. Only MWD logs were run. Cuttings samples were taken every 10 m from 260 m to TD.
The well was permanently abandoned on 16 January 1986.
Testing
No drill stem test was performed.
