Reservoir

Sandstones

Depostional environment

Fluvial, deltaic, shallow marine, tidal and estuarine

Trap

Mainly stratigraphic, but also structural (rotated fault blocks and halokinetic)

Stratigraphic

Stratigraphic (rotated fault blocks and halokinetic)

Source rock

Upper Devonian-Lower Carboniferous coal (Billefjorden Group) and Upper Permian shale (Tempelfjorden Group)

Upper Devonian - Lower Carboniferous coal (Billefjorden Group), Upper Permian shales (Tempelfjorden Group) and Upper Triassic delta plain
shales

Middle Triassic shale (Steinkobbe Formation), Lower Carboniferous   coal (Billefjorden Group) and Upper Permian shales (Tempelfjorden Group)         

Upper Devonian - Lower Carboniferous coal (Billefjorden Group), Upper Permian shales (Tempelfjorden Group) and Upper Triassic delta plain shales

Middle Triassic shale (Steinkobbe Formation), Lower Carboniferous coal (Nordkapp Formation) and Upper Permian shales (Tempelfjorden Group), Lower Permian marls (Tyrellfjellet Member equivalent)

Critical factors

Lateral extension of reservoir and reservoir qualities. The area has been affected by tilting, reactivation of faults, and Cenozoisk uplift and erosion
