Wintershall Dea spudded an appraisal of its 2018 Balderbra gas discovery in PL 894 on 22 January 2020. The âScarabeo 8â S/S was used to drill 6604/5-2 S. The well targeted three Upper Cretaceous Springar Formation sandstones, with the first expected at 3,633 m (3,389 m TVD), and was also designed to locate the GWC. Two sidetracks had been planned â one to the southwest (TD 4,120 m, 3,808 m TVD) and the other to the east (TD 4,258 m, 3,878 m TVD) â and Wintershall Dea also intended to carry out two DSTs. However, just a week after the main wellbore's 8-1/2" hole was still being drilled, the company was abandoning the well (on 19 February 2020). TD has not yet been confirmed but was planned at 4,126 m (3,863 m TVD).  Balderbra discovery well 6604/5-1 targeted a robust structural closure (Maastrichtian sand drape over older tilted fault blocks) with an amplitude anomaly between the Gullris (6604/2-1) and Gro (6603/12-1) wells. A gross gas column of 190 m across three separate sandstones totalling 90 m was encountered in the Springar Formation. The upper sandstone unit is thin with variable permeability, the middle sand is thicker (56 m gross) and laminated with 21% porosity, and the lower sand has a gross thickness of 129 m and 15% porosity. The three units are not in pressure communication and no GWC was encountered. Estimated recoverable reserves are between 247-671 Bcfg and 6-19 MMbc and the find could be developed as a tie-back to Aasta Hansteen, with first gas possible in 2027.   Interest in PL 894 is held by Wintershall Dea Norge AS (40% + operator), Equinor Energy AS (40%) and Petoro AS (20%).
