On 15 October 2018 Equinor returned to PL 615 to spud an exploration well on the Intrepid Eagle prospect. 7324/3-1 was drilled using the âWest Herculesâ S/S and is located approximately 13 km west of the 2014 Atlantis gas discovery. The well has made a new gas discovery in the upper part of the Triassic Snadd Formation. A 30 m gas column was present (net 20 m reservoir) with a GWC at 1,492 m. Estimated recoverable reserves are 350 â 700 Bcf gas. Gas was also proven in a lower part of the Snadd Formation â the same reservoir as Atlantis â but the sandstone was tight and so a total gas column height could not be established. Reserves for this reservoir are estimated at 35 â 140 Bcfg. The secondary objective in the Jurassic Sto Formation contained 15 m of water-wet sandstone. TD was reached at 1,709 m in the Snadd Formation and the well was abandoned around 20 November 2018.  The Intrepid Eagle drilling plan prognosed the Sto Formation reservoir at 901 m (22 m thick with a porosity of 20% and a permeability of 150 mD), the upper Snadd Formation reservoir at 1,525 m (40 m thick, 21% porosity, 200 mD permeability) and the lower at 1,680 m (30 m thick, 18% porosity, 15 mD permeability).   7325/1-1 targeted the Atlantis prospect and proved 55 m net of sandstone in the Snadd Formation with a 10 m gas column. A 10 m sandstone section with hydrocarbon shows was present in the Middle Triassic Kobbe Formation (the main objective) and the Lower Triassic Havert Formation also contained sand but with poor reservoir properties. Reserve volumes were estimated at 18-70 Bcfg.  Interest in PL 615 is divided between Equinor Energy AS (55% + operator), OMV (Norge) AS (25%) and Petoro AS (20%).
