General
Wildcat well 2/7-17 was drilled on a low relief structure to the southwest of the Eldfisk Field in the southern Norwegian North Sea. The primary objective was to test the Danian - Late Cretaceous limestone and chalk. Secondary objectives were the Late Cretaceous and Jurassic where irregular and lens-shaped structures on the seismic records were interpreted as possible sandstones with stratigraphically trapped hydrocarbons.
Operations and results
Well 2/7-17 was spudded with the semi-submersible installation Borgsten Dolphin on 24 June 1980 and drilled to 1600 m in Miocene sediments. After setting the 13 3/8" casing the casing collapsed, forcing abandonment of the well. The objectives were not reached. The well was drilled with seawater, native solids, gel, and bentonite.
No reservoir sections or hydrocarbon indications were reported in the penetrated sediment column.
No cores were cut and no wire line fluid samples taken.
The well was permanently abandoned on 12 July 1980 as a junk well.
Testing
No drill stem test was performed
Interval [m]: 594.00 - 1600.00
