Well history
WRITTEN BY THE NORWEGIAN OFFSHORE DIRECTORATE
General
Well 2/7-6, was drilled on the northern part of the Eldfisk structure in the North Sea. The primary objective was to test the Danian Limestone, and secondarily to test for possible further hydrocarbons in the Late Cretaceous of the Eldfisk structure.
Operations and results
Wildcat well 2/7-6 was spudded with the semi-submersible installation Ocean Viking on 31 March 1973 and drilled to TD at 3381 m in the Early Cretaceous Cromer Knoll Group. The well was drilled with seawater and hi-vis sweeps down to 488 m and with gypsum-lignosulphonate mud from 488 m to TD. Diesel was added to the mud below 488 m.
The Danian Ekofisk Formation and the underlying Tor Formation were found oil bearing and tested to yield commercial quantities of oil from top at 2911 m to 3078 m.
No cores were cut and no fluid samples were taken on wire line.
The well was permanently abandoned on 8 June 1973 as an oil appraisal well.
Testing
Four drill stem tests were performed, two in the Ekofisk Formation and two in the Tor Formation.
DST1 tested the interval 2973 to 2987 m and produced after acidization 46 Sm3 oil and 12400 Sm3 gas /day through a 96/64" choke. The GOR was 274 Sm3/Sm3, the gas gravity was 0.699 (air = 1), and the oil gravity was 36.6°API.
DST2 tested the interval 3069 to 3078 m and produced after acidization 158 Sm3 oil and 56900 Sm3 gas /day through a 96/64" choke. The GOR was 359 Sm3/Sm3 and th

About this data
Norwegian Offshore Directorate (Sodir) FactPages, mirrored nightly and used under the Norwegian Licence for Open Government Data (NLOD). Depths are metres along the wellbore from the kelly bushing unless a row gives its own unit; older cores are filed in feet. A zero the Directorate files for an unmeasured pressure, density, or temperature is shown as a dash.
