“…In fact, although the External Hellenides gained a renewed interest for hydrocarbon exploration in the last two decades (Grigoriou et al., 2019; Karakitsios & Rigakis, 2007), with several plays discovered, no studies on fault‐related fluid circulation have been performed so far. In contrast, many studies regarding fault‐related fluid circulation were performed in the nearby Albanides fold‐and‐thrust belt (De Graaf et al., 2019; Graham Wall et al., 2006; Roure et al., 2010; Swennen et al., 2000; Van Geet et al., 2002; Vilasi et al., 2006, 2009), where important hydrocarbon reservoirs were discovered (Bega & Soto, 2017; Zelilidis & Maravelis, 2015; Zelilidis et al., 2015).…”

Regional Scale, Fault‐Related Fluid Circulation in the Ionian Zone of the External Hellenides Fold‐And‐Thrust Belt, Western Greece: Clues for Fluid Flow in Fractured Carbonate Reservoirs

We combined field mapping, structural and microstructural analyses, stable‐clumped isotope geochemistry, and U‐Pb dating of calcite veins and syn‐tectonic slickenfibres, to assess the regional scale fault‐related fluid flow during the evolution of the External Hellenides fold‐and‐thrust belt. We show that fluid circulation during forebulge uplift was characterized by cold meteoric water‐derived fluids, from which calcite precipitated and sealed bed‐perpendicular joints likely formed during burial. Fluid circulation during foreland flexuring and early layer‐parallel shortening was characterized by warm fluids buffered by the carbonate host rock, which circulated through extensional faults and bed‐parallel veins. Mixing with meteoric‐derived fluids also occurred at this stage of tectonic evolution. Fluid circulation during the late stage of thrust wedge accretion and post‐orogenic extension at 1.6 ± 1 Ma was characterized by increasing dominance of cold meteoric water circulating in strike‐slip and normal faults. The ingress of external meteoric‐derived fluids was controlled by throughgoing fault conduits, while host rock‐buffered fluids were confined in isolated structures such as minor faults and veins. We developed a conceptual model of fault‐related fluid circulation, which invokes a transition from an open fluid system during forebulge uplift, to a semi‐closed fluid system during foreland flexuring and early layer‐parallel shortening, and to an open system during late thrust wedge accretion and post‐orogenic extension. This type of fluid circulation can have impact on fluid migration/leakage, including hydrocarbons, into or outside potential reservoirs in the highly prospective Hellenides‐Albanides fold‐and‐thrust belt, a renovated frontier for hydrocarbon exploration in the Mediterranean area.This article is protected by copyright.

“…The majority of European hydrocarbon reserves (excluding Russia) is located in the North Sea region within the Northern Permian basin, where reservoirs ranging from Carboniferous to Tertiary are present, e.g., [8], although the Adriatic region also has a long exploration history concerning hydrocarbon potential, e.g., [9,10], France, e.g., [11,12], Spain, e.g., [13], Italy, e.g., [14,15], Vienna Basin, e.g., [16], the Carpathians and their foreland in Czech, Poland, Ukraine, and Romania, e.g., [17][18][19][20][21][22][23], Transylvania, e.g., [20,24], Eastern Ukraine, e.g., [25] and the Black Sea, e.g., [26]. In Poland, new small-or mediumsized gas and oil fields continue to be discovered (e.g., Brzyska Wola, Czarna Wieś, Olchowiec, Pniewy, Rogoźnica, Wielichowo W, Gnojnica gas fields with total reserves of ~5.8 BCM/206 BCF, and Połęcko oil and gas field of total reserves of gas ~2.3 MCM/81 MCF and oil ~12.3 kTOE/87.6 MBOE; all of them documented by the Polish Oil and Gas Company in 2019-2020 in the Carpathian Foredeep and Polish Lowland) [1,2], which suggests the existence of still-unexplored regions.…”

New Opportunities for Oil and Gas Exploration in Poland—A Review

et al. 2022

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.
