“…The porosity of Rotliegend sandstones is 15-20% on average, and permeability varies from 2.5 to 60 mD, e.g., [70]. The sediments of the Upper Rotliegend are mainly eolian and less commonly fluvial facies (Figures 3 and 7) [55,95,[113][114][115][116][117]. The gas accumulated within the Rotliegend is almost free of higher gaseous hydrocarbons and hydrogen sulfide but has admixtures of helium of up to 0.3-0.45%.…”

Reserves totaling ~142 BCM (5 TCF) of natural gas trapped in 306 fields and ~22 MTOE (~157 MMBOE) of crude oil in 87 fields have been discovered. The prospection, exploration, and production of hydrocarbons are licensed: an entity interested in these kinds of activities needs to have concession, which is granted by the Polish Ministry of Climate and Environment for 10 to 30 years according to one of two independent ways — international tender or open door procedure. In this review, the most prospective areas for oil and gas exploration in Poland, selected by the Polish Geological Survey, and announced as dedicated for the next 6th tender round, planned in the second half of 2022, are described. These are: Block 413–414, Block 208, Cybinka–Torzym, Zielona Góra West, and Koło areas. The main exploration target of these tender areas is related to conventional and unconventional accumulations of gas and oil in the Carpathian basement, Carpathian Foredeep, and Outer Carpathians (Block 413–414), as well as in the Carboniferous, Permian Rotliegend, Zechstein Main Dolomite (Block 208, Cybinka–Torzym, Zielona Góra West), and in the Mesozoic of the Polish Lowlands (Koło). The second way of granting concession in Poland is the so-called open door procedure, in which an entity may apply for a concession for any other area selected on its own.

“…However, in petroleum exploration practice, terrigenous complexes of Permian in Poland are traditionally subdivided as non-reservoir Autunian and generally prospective Saxonian. The latter is represented by eolian and fluvial sandstones, playa mudstones and siltstones [35,37,38]. A maximum thickness of the Rotliegend continental clastic sediments in the MPT reaches 1400 m [39].…”

New seismic data and the completion of the K-1 petroleum exploratory well, located close to the axial zone of the Mogilno-Łódź Trough (Polish Lowlands) delivered new insight into local structural, tectonic, facial and thermal variability of this geological unit. In this paper, the two variants of 3D models (SMV1 and SMV2) of Permian-Mesozoic strata are presented for the salt pillow related Kłecko Anticline, while resources assessment was confined to the Rotliegend Enhanced Geothermal System (EGS) type reservoir, that is divided into Playa, Eolian and Fluvial facies-based complexes. Using very conservative assumptions on the methods of the EGS reservoir development, authors assessed that heat in place and technical potential for eolian sandstones are about 386 PJ and ca. 2814 kW, respectively, and for Fluvial 367 PJ and ca. 2850 kW in relation to the volume of 1 km3 at depths of about 5000 m b.s.l. The authors recommend for the further development of the Eolian complex because of its low shale content, influencing the high susceptibility to fracking. The presented research is the first Polish local resources assessment for an EGS reservoir in sedimentary Rotliegend, within thermal anomaly below the salt pillow, which is one of over 100 salt structures mapped in Poland.

Dryland flu vial sys tems have been de scribed from many an cient and mod ern, pre dom i nantly tec toni cally-con trolled sed i men tary bas ins across the globe. This study pro vides de tailed sedimentological anal y sis and palaeoenvironmental in ter pre ta tion of the low er most part of the early Perm ian (?Asselian) Krajanów For ma tion ex posed within the con ti nen tal, fault-bounded Intra-Sudetic Ba sin (ISB), lo cated on the NE pe riph ery of Bo he mian Mas sif. High-res o lu tion sedimentological log ging and fa cies anal y sis in di cate that the early Perm ian flu vial system in this area was dom i nated by ephem eral flu vial pro cesses in flu enced strongly by a semi-arid to arid cli mate. Rapid (?cat a strophic) flood events led to ep i sodic sed i men ta tion of ver ti cally and lat er ally amal gam ated flu vial chan nel infills, with abun dant up per flow re gime struc tures as well as poorly channelized, lat er ally ex ten sive sheet-like bod ies of sand stone. The overbank de pos its are poorly pre served due to fre quent lat eral shift ing of the chan nels. Soft-sed i ment de for ma tion structures formed due to events of river bank col lapse as well as de bris flow fa cies point to high-en ergy, wan ing flows.
