Equinor spudded an exploration well targeting the Sputnik prospect in PL 855 on 18 June 2019 using the âWest Herculesâ S/S. 7324/6-1 is located approximately 30 km northwest of the Wisting discovery and approximately 6 km from the Gemini North discovery, drilled in 2017, in the same licence. The well was targeting a large channel system in the Upper Triassic Snadd Formation and the Middle Jurassic Sto Formation was a secondary target. Gas above oil was expected in the Sto Formation while just oil was expected in the Snadd Formation. Equinor drilled to 746 m and, for a period of around two weeks, temporarily suspended the well whilst waiting for BOP repairs and maintenance to be completed. The well was then drilled to TD at 1,600 m in the Snadd Formation. A 15 m oil column has been proven in the middle part of the Snadd Formation with an OWC at 1,354 m. The reservoir quality is poor. The upper and lower parts of the Snadd Formation also contained sandstones (60 m and 45 m respectively), but again quality was poor and both sands were water-wet. The Sto Formation contained a good quality, water-bearing sandstone which was 20 m thick. Estimated recoverable reserves are 20-65 MMboe. The well was abandoned on 31 July 2019.  7325/4-1 was drilled in 2017 targeting the Gemini North prospect. The well had objectives in the shallow Jurassic Realgrunnen Group (743 m) and the Upper Triassic Snadd Formation (812 m). Both were expected to contain oil similar to nearby Wisting. However, instead of the anticpated oil, gas was discovered in the main objective. A 19 m gas column (no GWC) was proven in the Middle Jurassic Sto Formation, which had good reservoir quality, and a 5 m oil column was encountered in a poor quality Snadd Formation. Estimated recoverable reserves were reported to be 14 â 35 Bcfg and 0.6 â 1.9 MMbo and the find was declared non-commercial.    Equinor Energy AS operates PL 855 with a 55% interest. It is partnered by OMV (Norge) AS (25%) and Petoro AS (20%).
7324/06-01 (Sputnik) (Equinor 55% op. OMV 25%, Petoro  20%) in PL 855 (30 kms NE of the Wisting disc.), P&A, oil disc. encountered poor reservoir quality sands in various parts of the Snadd Fm and 20m of good quality aquiferous sands in the Sto Fm, preliminarily discovery size estimated at 19 â 63 MMbbbl of oil. Fluid samples from the well contained light oil and water. TD=1569m, WD=449m
