Well history

WRITTEN BY THE NORWEGIAN OFFSHORE DIRECTORATE

General

Well 30/10 4 was drilled on the northern tip of the Frigg Field. Its main purpose was to explore a deep-seated closure at Middle Jurassic level. This was a secondary target in the 30/10-1 well, but it was not reached in this well, which was terminated in the Late Cretaceous due to high-pressure problems.

Operations and results

Well 30/10-4 was spudded with the semi-submersible installation Neptune 7 on 11 September 1974 and drilled to TD at 758 m. At this point the drill string was lost in the hole. Fishing was unsuccessful and the well was plugged back and junked. The well was abandoned on 25 September 1974.

Testing

No drill stem test was performed
