Equinor and its partners in production licence 1128 (PL 1128) in the Norwegian Sea have made a commercial gas discovery through the drilling of wildcat well 6605/1-2 S near the Aasta Hansteen field.
The discovery, Obelix Upflank, was made 23km south of the Irpa gas discovery, and 350km west of Sandnessjøen. It was confirmed by the drilling of the appraisal well 6605/1-2 A. Equinor (70%) is partnered by Wintershall Dea (10%) and Petoro (20%) in PL 1128, which was awarded in APA 2020.
The Obelix Upflank discovery is estimated to hold 2-11bn standard cubic metres of recoverable gas, which is nearly 12.6-69.2m barrels of oil equivalent.
The Norwegian Petroleum Directorate (NPD) said well 6605/1-2 S intersected three sandstone layers in the Springar Formation, with the reservoir quality being moderate to good.
The uppermost sandstone layer of a thickness of nearly 10m was gas-bearing. The 35m middle sandstone layer saw a 2m gas column intersected, and the gas/water contact was proven at nearly 3,190m below sea level.
The 6605/1-2 S and 6605/1-2 A wells were drilled by the Deepsea Stavanger drilling rig to vertical depths of 3,330m and 3,327m, respectively, below sea level. Obelix Upflank marks the first hydrocarbons discovery made in Norwegian waters in 2023.
