General

Well 31/6-4 was drilled in the southern part of the Troll East gas province. The main purpose was to appraise and test possible oil and gas accumulations in sandstones of Late to Middle Jurassic age.

Operations and results

Appraisal well 31/6-4 was spudded with the semi-submersible installation Deepsea Bergen on 5 March 1984 and drilled to TD at 820 m in Eocene sediments. After setting of the 30" casing a 12 1/4" pilot hole was drilled. When opening the pilot hole to 26" hole, the hole holed kicked off from the pilot hole and deviated to 12.75 deg. at 662 m. Because of the deviation it was decided to junk the well. The well was drilled with spud mud.

No cores were cut and no fluid samples taken.

The well was junked and abandoned on 16 March as a dry well.

Testing

No drill stem test was performed
