Exploration well on Skirne Øst, a low relief structural/stratigraphic trap with a Hugin Sandstone objective and possible fill/spill from the Skirne Field. Down-thrown against horst block structure to east with normal fault to south and dip-closure to north and west. Gas/condensate in high net/gross Hugin at 2,459 m (2,307 m TVDSS) with 9 m column to gas-water contact at 2,468 m (2,316 m TVDSS) in 36 m gross reservoir. Contact was 88 m high to prognosis and reserves significantly less than anticipated. Depletion 36.6 bar relative to virgin pressure due to Skirne Field production.
