“…Detailed petrographic analyses can be found in the previous studies by Becker et al (2017), Wüstefeld et al (2017a and Busch et al (2019). Their results indicate a subordinate control on reservoir quality by differences in the detrital composition.…”

“…4; see data table in online archive). All the sandstones show wide ranges of grain sizes: fi ne-to coarse-grained at Piesberg (Wüstefeld et al, 2017a), medium-to coarse-grained at Woitzel, fi ne-to coarse-grained at Hüggel (Becker et al, 2017), fi ne-to medium-grained at Well A, and very fi ne-to coarse-grained at Well B (Busch et al, 2019). Average grain sizes were 0.4 mm in the outcrop sandstones and 0.3 mm in the subsurface sandstones.…”

“…This study comprises of fluvio-eolian sandstones only, consequently a population bias against a strong control depositional control due to the lack of depositional system variety is introduced into the data set. As opposed to Heidsiek et al (2020) a facies dependent reservoir control on plug-scale reservoir quality analyses cannot be delineated in Flechtingen Sandstones, as is also supported by previous studies in similar arid or semi-arid fluvio-eolian deposits (Busch et al 2019(Busch et al , 2020Kunkel et al 2018;Monsees et al 2020a). The effect of grain size on permeability is also interpreted to be partly caused by a population bias, which is also discussed by Wadsworth et al (2016).…”

“…To characterize a reservoir, the knowledge of its rock properties (e.g., lithology, porosity and permeability), diagenetic alterations controlling not only porosity and permeability but also affecting mechanical properties, structural inventory as the fracture network, the heat transfer, and all resulting interactions are crucial (Becker et al, Published by Copernicus Publications on behalf of the European Geosciences Union. Busch et al, 2019Busch et al, , 2020. In recent years, outcrop analog studies aiming at providing high-resolution data for a subsurface reservoir model have been increasingly supported by the use of digital techniques as UAS and terrestrial laser scanning to complement traditional fieldwork data (e.g., Becker et al, 2018;Cawood et al, 2017;Hodgetts, 2013;Walter et al, 2020;Wüstefeld et al, 2018).…”
