Area

Ribban Basin, Vestfjorden Basin, Utrøst Ridge, Træna Basin, Harstad Basin

Halten Terrace, Nordland Ridge, Dønna Terrace, Revfallet Fault Complex

Helgeland Basin

 

Reservoir rock

Sandstone

Depositional environment

Coastal, deltaic and shallow marine

Trap

Rotated fault blocks

Source rock

Upper Jurassic shale (Spekk Formation) and Upper Triassic to Lower Jurassic coal beds (Åre Formation)

Upper Triassic to Lower Jurassic coal beds (Åre Formation) and possibly older source rocks (Permian (ref. stratigraphic borehole 6611/9-U-1), Devonian)

Critical factors

Reservoir quality, sufficient source rock and migration, nhjl,jm-1, nhjl,jm-3: uplift and erosion, nhjl,jm-2: seal integrity due to high reservoir pressure
