General

Well 31/5-1 was drilled as an appraisal well at the southern part of the Troll West Field. The purpose of the well was to test the reservoir qualities, the oil/gas columns, and the hydrocarbon/water contact in the area.

Operations and results

Appraisal well 31/5-1 was spudded with the semi-submersible installation Treasure Saga on 5 September 1983. The well was drilled with seawater and hi-vis pills all through. After drilling to 860 m and setting the 20" casing, the BOP was run on riser. When the BOP was 12 m above the well head the drill pipe elevator broke, and the BOP dropped down and damaged the well head. The BOP and some riser joints were recovered before the rig was towed to Bergen where the BOP was changed.

No cores were cut and no wire line fluid samples were taken.

The well was abandoned on 30 September 1983 as a junk well. After repairs Treasure Saga returned to the location on 5 October 1983 to spud replacement well 31/5-2.

Testing

No drill stem test was performed.
