| الوصف: | Carboniferous organic-rich mudrocks are proven source rocks for conventional gas systems in Northwestern Europe and have sourced most of the gas found in the Rotliegend sandstones (di Primio et al., 2008). They are therefore considered as one of the stratigraphic horizons in the North German Basin that potentially could host unconventional gas occurrences. Recent gas-in-place (GIP) estimates of the German Federal Institute for Geosciences and Natural Resources (BGR) attribute 3.1–13.9 Bcm of shale gas to fine-grained sediments in depths between 1,000–5,000 m of which ∼ 40 % are assigned to carbonaceous mudrocks of the Lower Carboniferous (Ladage et al., 2016). The research and exploration activities on Carboniferous sediments in Germany in the last decades led to an overall good understanding of the formation and the collection of vast amount of data. However, despite the numerous boreholes that have been drilled to explore for conventional hydrocarbons in these successions, the potential for shale gas resources remains unassessed. In this integrated study, the potential for shale gas occurrences in Lower and Early Upper Carboniferous sediments is evaluated based on data compiled from different sources. The aim of this study is to elucidate the interrelationship of depositional features, rock characteristics and diagenetic influences on the governing processes for shale gas occurrences by incorporating: • a comprehensive literature database that emerged from intense research on various aspects of petroleum systems in general and unconventional shale gas systems in particular, • field data, e.g., from well reports, and • new laboratory measurements. The results of the initial shale gas and reservoir quality assessment conducted through comparison with successful U.S. shale gas system parameters and the detailed geochemical, petrographic and petrophysical measurements reveal, that heterogeneity in the investigated sample set is manifold. In general it seems, that variations too small to be resolved by the ... |
