Barents Sea - Carboniferous to Permian plays

	Group/Formation	Age	Area	Reservoir rock	Depositional environment	Trap	Source rock	Critical factors	Examples of discoveries	Examples exploration wells
bcu,pl-3 (unconfirmed)	Gipsdalen Group with Falk and Ørn Formations	Late Bashkirian-Late Sakmarian	Finnmark Platform	Limestones and dolomites	Carbonate buildups in shallow marine, warm water	Stratigraphic, but a combination of stratigraphic and structural cannot be excluded	Upper Devonian-Lower Carboniferous shales, Lower Carboniferous coal (Billefjorden Group), Upper Permian shales (Tempelfjorden Group), Middle Triassic shales (Steinkobbe Formation).	Presence of mature source rock. Reservoir quality. The area has been affected by tilting, reactivation of faults, and Cenozoic uplift and erosion.		7128/4-1 7128/6-1
bcu,pl-4	Gipsdalen Group with Falk and Ørn Formations	Late Bashkirian-Late Sakmarian	Loppa High and Polheim Sub-platform	Limestones and dolomites	Carbonate buildups in shallow marine, warm water	Stratigraphic, but a combination of stratigraphic and structural cannot be excluded	Lower Carboniferous coal (Billefjorden Group) and Upper Permian shales (Tempelfjorden Group).	Presence of mature source rock. Reservoir quality. The area has been affected by tilting, reactivation of faults, and Cenozoic uplift and erosion.	7220/11-1	7220/6-1
