The Transocean Spitsbergen semisub drilled an exploration well and follow-up sidetrack on the Røver Sør structure in PL 923, which is 10 km northwest of Troll in 348 m of water.
Preliminary assessment suggests 17 MMboe to 47 MMboe recoverable, with oil accounting for the majority of the resource. Both wells encountered hydrocarbons in three Jurassic Brent Group sandstone reservoirs (Ness, Etive and Oseberg formations).
Transocean Spitsbergen has plugged and abandoned both wells and will next drill a wildcat in PL 554 in the northern Norwegian North Sea.
Equinor’s previous six discoveries in the area were Echino Sør (2019); Swisher (2020); Røver Nord and Blasto (2021); and Toppand and Kveikje (2022). These could hold total volumes of about 350 MMboe.
Equinor is working with its partners on a potential coordinated development of the discoveries through existing infrastructure. Along with others, Røver Sør could be tied back to the Troll Field center.
The next exploration well in this area will target the Heisenberg prospect, with further exploration drilling to follow later in 2023.
