General

Well 15/12-2 was drilled in order to evaluate Jurassic formations on a seismic structure located in the eastern part of block 15/12. The principal objective of the 15/12-2 well was to test the Dogger (Hugin Formation) sandstone, where oil shows had been encountered in the 15/12-1 well. A secondary object was a possible sand in the Paleocene.

Operations and results

Wildcat well 15/12-2 was spudded with the semi-submersible installation Ross Rig on 7 January 1976 and drilled to TD at 2924 m in Late Permian Zechstein anhydrite. The well was drilled with a lignosulphonate mud system.

No sand was found in the Paleocene. The Hugin Formation sandstone was found 304 meters higher than in the 15/12-1 well. The sandstone proved to have very good reservoir qualities, but was completely water bearing. There were sandstone stringers in the lower part of the Heather Formation. The Hugin Formation sand was cored from 2823 m to 2835.4 m, with no show. No fluid sampling was attempted in the well.

The well was permanently abandoned as a dry well on 27 February 1976.

Testing

No drill stem test was performed
