On 13 May 2019 Equinor spudded a second well on the Korpfjell prospect in PL 859 (delayed from summer 2018). 7335/3-1 was located approximately 8 km south of the first Korpfjell well and was drilled using the âWest Herculesâ S/S. TD was reached in the Lower Triassic Havert Formation and was abandoned as a dry hole around 14 June 2019. Tight sandy intervals were encountered in the Triassic Havert Formation, Klappmyss Formation and Kobbe Formation (125 m). In the Triassic Snadd Formation sandy intervals of poor reservoir quality were encountered, with some sandstone layers containing traces of gas. Whilst not a target, the Realgrunnen Group was investigated and proven to have around 170 m sandstone reservoir of moderate to good quality.   The hotly-anticipated 2017 Korpfjell exploration well 7435/12-1 proved a 34 m gas column in the Lower-Middle Jurassic Sto Formation with estimated recoverable reserves of 212-424 Bcfg (40-75 MMboe) which in this location is non-commercial. The prospect was mapped with a closure of 850 sq km, which is 3-4 times the closure of Johan Sverdrup, and it was the first well to be drilled in the recently awarded 23rd Round acreage near the Russian border.   Interest in PL 859 is divided between Equinor Energy AS (30% + operator), DNO Norge AS (20%), Petoro AS (20%), ConocoPhillips Skandinavia AS (15%) and Lundin Norway AS (15%).
7335/03-01 (Korpfjell Deep) expl. (Equinor op, DNO, Petoro, COP, Lundin) in PL 859, ab. 8km SE of Korpfjell gas find that was non-commercial, WD=239m, P&A dry at TD=4268m, (L. Havert fm), targets Klappmyss, Havert, Snadd + Kobbe fmâs. Encountered sandy and mainly tight intervals at both targets, some thin sst layers in the Triassic revealed traces of gas, around 170m of sst reservoir of moderate-to-good quality were proven in the Realgrunnen sub-group of Triassic age that was not targeted by the well.
