General
Well 2/4-12 was drilled on a location ca 3 km west of the Ekofisk Field. The primary objective was to test the chalks in the Late Cretaceous and Early Paleocene.
Operations and results
Wildcat well 2/4-12 was spudded with the semi-submersible installation Ocean Viking on 28 July 1975 and drilled to TD at 3383 m in the Late Cretaceous Tor Formation. No significant problems were encountered in the operations.
The well was found dry. There were no shows while drilling and electric logs showed low porosities and high water saturations. Five cores were cut. Core 1 was cut in the basal part of the Våle Formation and topmost Ekofisk Formation. Cores 2 and 3 were cut in the Ekofisk Formation, and cores 4 and 5 in the Tor Formation. No wire line fluid samples were taken.
The well was permanently abandoned on 8 September 1975 as a dry well.
Testing
No drill stem test was performed
