“…The Bunter Sandstone Formation is a geothermal target in the North German Basin onshore Denmark and Germany (Hurter & Schellschmidt, ; Mathiesen et al ., ; Mahler et al ., ; Agemar et al ., ) and has CO 2 storage potential in both these regions and in the North Sea (Brook et al ., ; Bentham & Kirby, ; Heinemann et al ., ; Mitiku & Bauer, ). The Bunter Sandstone Formation is a gas‐ and minor oil‐producing reservoir in the North Sea (Fisher & Mudge, ; Underhill, ; de Jager & Geluk, ; Bachmann et al ., ) and is used as an aquifer onshore England (Downing, ).…”

Zircon U–Pb geochronometry, heavy mineral analyses and conventional seismic reflection data were used to interpret the provenance of the Lower Triassic Bunter Sandstone Formation. The succession was sampled in five Danish wells in the northern part of the North German Basin. The results show that sediment supply was mainly derived from the Ringkøbing‐Fyn High situated north of the basin and from the Variscan belt located south of the basin. Seismic reflection data document that the Ringkøbing‐Fyn High was a local barrier for sediment transport during the Early Triassic. Hence, the Fennoscandian Shield did not supply much sediment to the basin as opposed to what was previously believed. Sediment from the Variscan belt was transported by wind activity across the North German Basin when it was dried out during deposition of the aeolian part of the Volpriehausen Member (lower Bunter Sandstone). Fluvial sand was supplied from the Ringkøbing‐Fyn High to the basin during precipitation events which occurred most frequently when the Solling Member was deposited (upper Bunter Sandstone). Late Neoproterozoic to Carboniferous zircon ages predominate in the Volpriehausen Member where the dominant age population with a peak age of 337 Ma corresponds to the culmination of Variscan high‐grade metamorphism, whereas a secondary age population with a peak at 300 Ma matches the timing of volcanism and magmatism at the Carboniferous/Permian boundary in the northern Variscan belt. Parts of the basement in the Ringkøbing‐Fyn High were outcropping during the Early Triassic and zircon ages similar to this Mesoproterozoic basement are present in the Bunter Sandstone. The heavy mineral assemblage of the Solling Member is uniform and has a high garnet content compared to the contemporaneous sediments in the Norwegian‐Danish Basin and in the southern part of the North German Basin. This finding confirms that a local source in the Ringkøbing‐Fyn High supplied most of the fluvial sediment in the northern part of the North German Basin. The northernmost part of the Bunter Sandstone is situated on a platform area that is separated from the basin area by a broad WNW–ESE‐oriented fault zone. The most promising reservoir in the basin area is the aeolian Volpriehausen Member since the sandstone has a wide lateral distribution and a constant thickness. The alluvial to ephemeral fluvial Solling Member may be a good reservoir in the platform area and marginal basin area, but the complex sand‐body architecture makes it difficult to predict the reservoir quality.

“…Accordingly predictive modelling of CO 2 reservoirs can profit from geothermal simulations but needs to integrate additional processes. Mitiku and Bauer (2013) quantify the different amounts of CO 2 that can be stored in a geological anticline reservoir dependent on different possible scenarios of well configuration and reservoir properties. Kempka and Kühn (2013) provide another example for predictive CO 2 modelling and validate numerical simulations of CO 2 arrival times and reservoir pressure with observations from the Ketzin pilot site in Germany.…”

“…The Barents Sea is being considered for the long-term geological storage of CO2 (e.g., Riis & Halland, 2014), given it contains many dome-like structures and anticlines (e.g., Mitiku & Bauer, 2013). The Samson Dome is a large, faulted, Mesozoic dome in the SW Barents Sea.…”

The growth of normal faults can influence subsurface fluid flow and entrapment within rift basins. However, fault seal studies typically view faults as static structures, with their growth and the potential related temporal changes in hydraulic properties being ignored. In this study, we use borehole data and a high-quality 3D full-stack depth migrated seismic reflection volume to analyse the growth history of the normal fault network in the Samson Dome area, SW Barents Sea. We specifically focus on how the kinematic history of normal faults impacts their sealing properties, whilst also considering their origin and implications for regional salt tectonics. We show that the faults formed during two distinct phases in the Late Triassic and Middle Jurassic-to-Early Cretaceous, and two phases of dome growth occurred in the Late Triassic and Late Cretaceous, challenging existing proposals for the timing of the development of structure. The salt-tectonic origin of the Samson Dome itself remains enigmatic, although mechanical considerations suggest existing models require refinement. Our fault seal analysis reveals a correlation between displacement patterns and sealing potential, as reflected in the Shale Gouge Ratio (SGR) values of different fault groups. More specifically, faults that grew via vertical linkage of initially isolated segments and experienced potential reactivation exhibit lower SGR values, implying a higher likelihood of across and along-fault leakage. Conversely, faults lacking evidence for reactivation or vertical linkage show higher SGR values, suggesting better sealing potential. Notably, the accuracy of our fault seal analysis is greatly influenced by the calculation methods used for Vshale, particularly for faults with low displacement. Our study provides valuable insights into the faulting, development, and sealing potential of the Samson Dome area. We also highlight the importance of careful consideration of Vshale calculation methods when conducting fault seal analysis.
