Vertical exploration well on Fosen prospect. Stratigraphic pinch-out with Sleipner, Hugin and Intra-Draupne objectives sealed by overlying Cromer Knoll claystones and underlying Smith Bank. Seal considered main risk. Upper Jurassic absent, with thin Hugin and 112 m gross Sleipner subcropping BCU at 2,370 m TVDSS. High quality reservoir in Sleipner, with 90 m net water-wet sand. Minor shows may result from OBM contamination. Sands in Statfjord (2,488 m TVDSS) and Smith Bank (2,530 m TVDD to TD) may have breached base-seal.
