Well history
WRITTEN BY THE NORWEGIAN OFFSHORE DIRECTORATE
General
Well 2/7-9 is located in the Ål Basin south of the Eldfisk structure in the southern North Sea. The main purpose of the well was to test Danian -Cretaceous limestone and Jurassic sandstone on a north-south trending anticline 6 - 8 km south of Eldfisk, where these intervals had proven commercial oil in several wells.
Operations and results
Appraisal well 2/7-9 was spudded with the jack-up installation Zapata Nordic on 25 December 1973 and drilled to TD 4448 m in Devonian sediments.
Appraisal well 2/7-9 was spudded with the jack-up installation Zapata Nordic on 25 December 1973 and drilled to TD 4448 m in Devonian sediments. The Danian Limestone (Ekofisk Formation) came in at 3086 m. It was expected to be 90 m thick while 77 m was found. The Late Cretaceous Chalk (Cromer Knoll Group) was anticipated to be 695 m thick, but a greater thickness of 800 m was found. Good shows were seen in both intervals, but no hydrocarbons were produced when tested. Sands initially dated Late Jurassic were encountered at 4313 m and proved to be hydrocarbon bearing with a 111 m pay section with average porosity of 13% and 55% oil saturation. A clear OWC was found at 4424 m.These sands have later been interpreted as of Devonian age.
No cores were cut and no wire line fluid samples were taken.
The well was permanently abandoned on 10 April 1974.
Testing
Three drill stem tests were conducted in the well.
DST 1 tested the interval 4313 to 4356 m in the Devonian sandstone

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.
