Barents Sea – Triassic plays
Group/Formation | Age | Area | Reservoir rock | Depositional environment | Trap | Source rock | Critical factors | Examples of discoveries | Examples exploration wells | |
---|---|---|---|---|---|---|---|---|---|---|
brl-1 | Sassendalen Group with Havert Formation | Indus | Finnmark Platform, Hammerfest Basin, Hoop, Måsøy, Nyslepp and Troms-Finnmark fault complex, Loppa High, Maud Basin, Mercurius High, Nordkapp Basin, Norsel High and Swaen Graben | Sandstones | Fluvial, deltaic, shallow marine, tidal and estuarine | Mainly stratigraphic, but also structural (rotated fault blocks and halokinetic) | Upper Devonian-Lower Carboniferous coal (Billefjorden Group) and Upper Permian shale (Tempelfjorden Group) | Lateral extension of reservoir and reservoir qualities. The area has been affected by tilting, reactivation of faults, and Cenozoisk uplift and erosion |
|
|
brl,rm-4 | Sassendalen Group with Klappmyss and Kobbe Formations | Induan-Anisian | Finnmark- and Bjarmeland Platform and Nordkapp Basin | Sandstones | Fluvial, deltaic, shallow marine, tidal and estuarine | Mainly stratigraphic, but also structural (rotated fault blocks and halokinetic) | Upper Devonian - Lower Carboniferous coal (Billefjorden Group), Upper Permian shales (Tempelfjorden Group) and Upper Triassic delta plain shales | Lateral extension of reservoir and reservoir qualities. The area has been affected by tilting, reactivation of faults, and Cenozoisk uplift and erosion |
|
|
brl,rm-5 | Sassendalen Group with Klappmyss and Kobbe Formations | Induan-Anisian | Loppa High Maud Basin, Mercurius High, Hoop Fault Complex and western part of the Bjarmeland Platform | Sandstones | Fluvial, deltaic, shallow marine, tidal and estuarine | Stratigraphic | Middle Triassic shale (Steinkobbe Formation), Lower Carboniferous coal (Billefjorden Group) and Upper Permian shales (Tempelfjorden Group) | Lateral extension of reservoir and reservoir qualities. The area has been affected by tilting, reactivation of faults, and Cenozoisk uplift and erosion |

bru-1 | Kapp Toscana Group with Snadd Formation | Ladinian-Early Norian | Finnmark- and Bjarmeland Platform, Nordkapp basin and Norsel High | Sandstones | Fluvial, deltaic, shallow marine, tidal and estuarine | Stratigraphic (rotated fault blocks and halokinetic) | Upper Devonian - Lower Carboniferous coal (Billefjorden Group), Upper Permian shales (Tempelfjorden Group) and Upper Triassic delta plain shales | Lateral extension of reservoir and reservoir qualities. The area has been affected by tilting, reactivation of faults, and Cenozoisk uplift and erosion |

bru-2 | Kapp Toscana Group with Snadd Formation | Ladinian-Early Norian | Loppa High, Maud Basin, Mercurius High, Fingerdjups Sub-basin, Veslemøy High, parts of Bjørnøya Basin, Stappen High, Bjørnøyrenna Fault Complex, Hoop Fault Complex and western part of Bjarmeland Platform | Sandstones | Fluvial, deltaic, shallow marine, tidal and estuarine | Stratigraphic (rotated fault blocks and halokinetic) | Middle Triassic shale (Steinkobbe Formation), Lower Carboniferous coal (Nordkapp Formation) and Upper Permian shales (Tempelfjorden Group), Lower Permian marls (Tyrellfjellet Member equivalent) | Lateral extension of reservoir and reservoir qualities. The area has been affected by tilting, reactivation of faults, and Cenozoisk uplift and erosion |
