Equinor used the âDeepsea Bergenâ S/S to spud a well on the Gunnvald prospect in PL 751 on 17 November 2018. 6407/11-1 lies approximately 12 km southwest of Draugen and 8 km south of Tau. The well, which was dry, encountered a 115 m section of the Tofte Formation with around 75 m comprising good to very good quality reservoir quality sandstone. In the Tilje Formation a 215 m section was penetrated with around 155 m comprising good to very good reservoir quality sandstone. The well reached TD at 2,175 m (2,152 m TVDSS) in the Are Formation and on 7 December 2018 the well was plugged and abandoned.   The Tau oil and gas discovery was made by BP in 1994 when the company held the area under PL 158. Good quality reservoir was confirmed in the Are Formation at 1,733 m but volumes are small and development is unlikely.  Equinor Energy AS operates PL 751 with an 80% interest. It is partnered by Petoro AS (20%).
