Well history
WRITTEN BY THE NORWEGIAN OFFSHORE DIRECTORATE
General
Well 24/9-2 was drilled in the Vana Sub-basin in the Southern Viking Graben of the North Sea. The well was located to test Danian and Early Paleocene sands. Dip closure at this level was enhanced by a seismic anomaly of a "build-up" shape within the Middle-Late Paleocene Heimdal sands.
Operations and results
Wildcat well 24/9-2 was spudded with the semi-submersible installation Borgny Dolphin on 13 June 1977 and drilled to TD at 2743 m in the Late Cretaceous Tor Formation. A total of 9.8 days was lost on various mechanical hole problems during. The well was drilled with seawater and gel down to 1554 m and with lignosulphonate / CMC / gel / seawater from 1554 m to TD.
The well penetrated a gross interval of 439 m of Paleocene sands. No sands were found in the Danian, which was of a marl and limestone lithology. Hydrocarbons in commercial quantities were not encountered. While drilling the gas detector showed two slight increases, one within the Late Paleocene (a thin intra-Sele Formation sandstone) and one within the Early Paleocene Sand. Fluorescence was observed in the samples from the Late Paleocene Sand. Log analysis proved a 3-meter hydrocarbon bearing interval in the Late Paleocene sand between 2101.5 and 2104.5 metres, and sidewall cores proved the presence of oil in this interval.
No cores were cut, and no wire line fluid samples were taken.
The well was permanently abandoned on 22 July 1977 as a well with shows.
Testing
No drill stem test was performed.

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.
