Well history
WRITTEN BY THE NORWEGIAN OFFSHORE DIRECTORATE
General
Exploration well 17/12-1 is located on the northern margin of the Egersund Basin in the North Sea, towards the Åsta Graben. Its primary target was Jurassic sands (Bream prospect) with estimated top at 2161 m (7090 feet) and with 61 m (200 feet) thickness. Sand developments within the Early Cretaceous and Triassic sections were regarded as secondary objectives. Planned TD was 8 m (25 feet) into the Zechstein salt.
Operations and results
Well 17/12-1 was spudded with the 3 leg jack-up installation Mærsk Explorer on 27 October 1971 and drilled to TD at 458 m in the 26" section where it was suspended on 1 November for later re-entry with a different rig, Ocean Viking.
Testing
No drill stem test was performed.
