| Group/Formation | Age | Area | Reservoir rock | Depositional environment | Trap | Source rock | Critical factors | Examples exploration wells | |
|---|---|---|---|---|---|---|---|---|---|
| bcl-3 | Billefjorden Group with Blærerot, Tettegras and Soldogg Formations | Tournaisian - Viséan | Finnmark Platform | Sandstone and conglomerates | Fluvial and alluvial, river and floodplain deposits | Structural and stratigraphic | Upper Devonian - Lower Carboniferous coal and carbonaceous shales (Billefjorden Group) | Preservation and leakage owing to tilting, reactivation of faults and Cenozoic uplift and erosion, especially for shallow and/or truncated structures. |
