Well history
WRITTEN BY THE NORWEGIAN OFFSHORE DIRECTORATE
General
Well 35/9-6 S was drilled on the Titan Prospect on the Måløy slope in the northern North Sea close to several hydrocarbon discoveries. The most important of these are the Gjøa field to the east and Aurora and Vega to the west. The objective was to test four target levels in the Jurassic with the Tarbert and Etive formations as primary targets and Callovian Intra Heather Formation sandstone and Cook Formation sandstone as secondary targets.
Operations and results
Wildcat well 35/9-6 S was spudded with the semi-submersible installation Bredford Dolphin on 29 September and drilled to TD at 3740 m (3689 m TVD) in Late Triassic sediments of the Lunde Formation. The well was drilled with Seawater with Hi-Vis Sweeps down to 465.5 m, with KCl/GEM mud (3-5 % glycol) from 465.5 m to 1723 m, with Performadril mud (3-5 % glycol) from 1723 m to 2925 m, and with Performadril HT mud (3-5 % glycol) from 2925 m to TD.
Oil and Gas-Condensate, was encountered over a gross column of 434 meters in the Viking, Brent and Dunlin Groups. Hydrocarbons were proven in 5 different stratigraphic levels:
· Intra Heather Formation sandstone of Callovian age with top at 3256.9 m (3206.4 m TVD) contained oil
· Tarbert Formation with top at 3426.6 m (3376.1 m TVD) contained

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.
