Well history
WRITTEN BY THE NORWEGIAN OFFSHORE DIRECTORATE
General
The well 6506/9-2 S was drilled on the Fogelberg prospect in a rotated fault block located on the Halten terrace north-northwest of the Smørbukk and Åsgard fields. The overall objective for the well was to test the hydrocarbon potential in the Middle/Lower Jurassic sandstones of the Fangst and Båt Groups. The expected hydrocarbon phase was light oil with associated gas similar to the nearby 6506/11-7 Morvin light oil discovery. The planned total depth for the well was 4783 m TVD RKB, fulfilling the license obligation of drilling 50 m into the Åre Formation (Båt Group). The well was defined as a HPHT well.
Operations and results
Wildcat well 6506/9-2 S was spudded with the semi-submersible installation West Alpha on 11 February 2010 and drilled to TD at 4805 m (4736 m TVD) in the Early Jurassic Åre Formation. The well started with a 9 7/8" pilot hole down to 1227 m to check for shallow gas. No shallow gas was encountered. The well was drilled vertical down to 1213 m. From there angle was built up to 13 deg at ca 1600 m and kept at approximately this angle down to ca 3900 m, and then falling off to vertical again from ca 4000 m to TD. The well was drilled without significant operational problems. It was drilled with seawater and sweeps down to 1219 m, with Glydril water based mud from 1219 m to 2126 m, and with Versatherm oil based mud from 2126 m to TD.
No hydrocarbons were encountered in the Lysing or Lange formations. High gas readings were encountered in the Lange Formation at 4022 m (3954 m TVD). This coincided with maximum recorded pore pressure in the well and low mud weight. With the correct mud weight circulated in place, the background gas r

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.
