Statoil, operator of production license 169, has concluded the drilling of wildcat well 25/11-28, 13km south of the Grane field in the North Sea. The well is dry, according to the Norwegian Petroleum Directorate.
The objective of the well was to prove petroleum in Upper Jurassic reservoir rocks (the Draupne formation) and in the Permian (the Rotliegend group). The well encountered 22m of sandstone in the Upper Jurassic, of which 7.5m is of good reservoir quality. Reservoir rocks were not proven in the Permian.
The well was drilled in 118m water depth, by the Songa Trym semisubmersible, to a vertical depth of 2563m below the sea surface. Extensive data acquisition and sampling have been carried out. The well will now be permanently plugged and abandoned.
