    Opis:
    Based on geochemical data of the Oligocene Menilite Shales in the Boryslav–Pokuttya, Skole (Skyba), Silesian (Krosno) and Dukla units in the Carpathians, between Krosno and Styi towns, 1D modelling of generation and expulsion processes of hydrocarbons has been carried out. These strata are characterized by mostly high organic matter content, the total organic carbon (TOC) content reaching up to 26 wt.%. The highest hydrocarbon potential was recorded in the Boryslav–Pokuttya and Skole units. Organic matter in the Skole (Skyba) Unit is immature; in turn, in the Boryslav–Pokuttya, Silesian (Krosno) and Dukla units it is mature enough for generating hydrocarbons. Results of the modelling reveal that during the deposition of flysch in all the above mentioned Outer Carpathian units the Menilite source rocks did not reach a level of thermal maturity high enough to generate hydrocarbons. Conditions of hydrocarbon generation were obtained in the thrusting stage of the Outer Carpathians. In general, the process of hydrocarbon generation began at depths of less than 2 km in the Polish part, and about 4 km in the Ukrainian part. The kerogen transformation level reached from 10% to to complete transformation as in the Suche Rzeki IG 1 well.The results of the modelling of hydrocarbon generation and expulsion from the source rocks of all the units reveal that the highest maturity and the highest generation potential were obtained by the Menilite Shales in the Silesian and Dukla units.

    Opis:
    2-D modelling of hydrocarbon generation, expulsion, migration and accumulation processes was carried out for the four (Middle Cambrian, Upper Cambrian-Tremadocian, Caradocian and Llandovery) source rock horizons. The petroleum potential of these source rocks is different, the highest being observed in the Upper Cambrian-Tremadocian horizon and the lowest in the Middle Cambrian one. The maturity of organic matter within these source units increases from the north-east to the south-west of the Polish part of Baltic region. The petroleum generation from these source rocks was highest in the Darlowo and Slupsk blocks as well as in the onshore part of the Leba Block. Expulsion took place mainly from the Upper Cambrian-Tremadocian source rocks and these rocks sourced almost all hydrocarbons accumulated within the Middle Cambrian sandstone reservoirs. Migration of hydrocarbons proceeded along fault zones. Almost all petroleum processes in the study area took place between the end of the Pridoli and the end of the Carboniferous. Moreover, during the Permian and the Mesozoic, part of the hydrocarbons remigrated within the reservoir. This process changed the setting and the volume of hydrocarbon accumulations. It was caused by the tectonic rebuilding of the basin and, in most cases, it led to the modification of accumulation range or to the dispersion of hydrocarbons.

    Opis:
    Two-dimensional modelling of hydrocarbon generation, expulsion, migration and accumulation pro- cesses in SE Poland between Tarnów and Rzeszów was carried out for five source rock horizons, i.e. the Ordo- vician, Silurian, Middle Devonian–Lower Carboniferous carbonates, Lower Carboniferous clastics, and Middle Jurassic. Five cross-sections in the study area allowed the reconstruction of timing and range of petroleum processes. The best source rocks related to the Ordovician and Silurian shales and mudstones reached “oil window” maturity within the entire study area and locally also reached the “gas window”. Generation of hydro- carbons was observed from all five source rocks, but the Ordovician and Silurian source rocks generated two and three times more hydrocarbons than the Lower Carboniferous and Jurassic source rocks, respectively. Expulsion took place only in case of the Lower Palaeozoic source rocks, but the volume of expelled hydrocarbons differed across the area. Hydrocarbons migrated from the Ordovician and Silurian source rocks to the Upper Jurassic (carbonates) and Upper Cretaceous (sandstones) reservoirs or to the Upper Palaeozoic carbonates in connection with the emplacement of the Carpathian thrust belt during the Miocene. Faults formed main migration pathways and hydrocarbons accumulated in structural and stratigraphic traps, located in the vicinity of faults. In places, traps are associated with a deep Miocene erosion surface. The onset of hydrocarbon generation took place during the Neogene, mainly the Miocene, but in the north, generation and expulsion started earlier – at the end of the Mesozoic.

    Opis:
    The geochemical characteristics of the Palaeozoic and Mesozoic strata of the basement of the Carpathian Foredeep depicted the Devonian and Carboniferous source rocks as the best source for hydrocarbon generation. Moreover, the Outer Carpathian sequence was geochemically characterized and proved capable of generating hydrocarbons. The oil-source rocks’ correlations indicated that the source of the condensate accumulated in the Łąkta field, while oil in the Grobla field. Maturity modelling identified Devonian source rocks as they reached a late phase of the “oil window” and, locally, even the “gas window”. The Carboniferous source rock was mature enough to start the generation processes. The generation started in the late Carboniferous, both in the Upper Silesian and Małopolska blocks. The main phase of the petroleum processes took place in late Neogene. The expulsion was observed only in the Devonian source rocks, and vertical migration by fault system in both blocks resulted in oil and gas accumulation in the Upper Jurassic carbonates and Upper Cretaceous sandstones. The petroleum modelling indicated the Devonian source for oil and gas fields in the study area. However oil-source rock correlation also suggests the presence of the Carpathian flysch source for hydrocarbons accumulated in the Łąkta field.

    Opis:
    Numerical modelling of the Carboniferous–Permian petroleum system in the Polish Basin was carried out using PetroMod software. The Carboniferous source rocks contain organic matter mostly of a humic nature (gas-prone Type III kerogen). Subordinately, only in the Lower Carboniferous deposits, kerogen of algal marine origin and mixed Type II/III kerogen occur. The quantity of dispersed organic matter is variable, but usually below 2% TOC. In the Carboniferous section, a progressive increase in the maturity of organic matter with depth was observed, from approximately 0.5% Rr at the top of the Westphalian in marginal parts of the Carboniferous basin to over 5.0% Rr at the bottom of the Lower Carboniferous in the eastern Fore-Sudetic Homocline. The thermo- genic generation of hydrocarbons continued from the late Westphalian (eastern Fore-Sudetic Homocline and partly Pomerania) throughout the Mesozoic, up to the Late Cretaceous. The advancement of this process is va- riable in different parts of the Carboniferous basin, reaching up to 100% of kerogen transformation in the zones of maximum maturity of organic matter. However, the most intensive periods of gas generation and migration were the Late Triassic and the Late Jurassic. The most prospective areas are located NE of Poznań–Kalisz line and SW of Poznań.

    Opis:
    The lower Paleozoic source rocks in the offshore part of the Gryfice and Kolobrzeg blocks (NW Poland) were studied through geochemical data and numerical modelling. The geochemical study revealed a presence of effective source rocks in Caradocian strata, but with low hydrocarbon potential. The remaining lower Paleozoic source rock horizons were not documented by core samples. The timing of hydrocarbon generation and expulsion was modelled for the K1-1/86 and L2-1/87 boreholes located in the Gryfice and Kolobrzeg blocks, respectively. 1-D and 2-D modelling indicated that in the Kolobrzeg Block the onset of petroleum generation occurred at the end of the Silurian and the beginning of the Devonian. Source rocks in the Gryfice Block reached the early stage of oil generation at the beginning of the Permian and generation processes were completed by the end of the Triassic. Migration of hydrocarbons from source rocks began in the Carboniferous in both the Gryfice and Kolobrzeg blocks and lasted to the end of the Mesozoic. During hydrocarbon migration, an intensive dispersion process was observed, caused by leaking along the fault planes. The modelling revealed that hydrocarbons may have accumulated in Devonian reservoirs. The lack of any discovered accumulations could be the result of hydrocarbon dispersion caused by tectonic deformation and intense vertical fault block movements.

    Opis:
    The Mesozoic strata in the southeastern Poland were geochemically characterized to determine their hydrocarbon potential on the basis of 483 core samples from 36 boreholes. The Lower and Middle Triassic, Middle and Upper Jurassic, and Lower and Upper Cretaceous turned out to be highly variable. Middle Jurassic rocks represent the highest geochemical quality. Their total organic carbon (TOC) contents range between 0.0 and 17.0 wt.%, with a median of 0.89 wt.%. The highest TOC was observed in the rocks of the Tarnawa 1 borehole. In the remaining boreholes analysed the organic carbon contents were much lower and usually did not exceed 1 wt.%. Gas-prone Type-III kerogen with an admixture of Type-II kerogen is present in the study area. The lowest TOC values were observed in the Cretaceous rocks, where median values were 0.05 wt.% and 0.04 wt.% for Upper Cretaceous and Lower Cretaceous strata respectively. Low TOC contents were also observed in the Lower Triassic and Upper Jurassic strata. Accordingly, those horizons could not be regarded as effective source rocks. The petroleum potential of these stratigraphic horizons is additionally significantly reduced by low maturity, below the threshold for the generation of hydrocarbons. The Mesozoic organic matter was found to be generally immature, i.e. below 0.5% of vitrinite reflectance.

    Opis:
    Comprehensive geochemical analyses (Rock-Eval pyrolysis, stable carbon isotopes, biomarkers and aromatic hydrocarbons and elemental composition of kerogen) provide an explanation of genetic relationships between dispersed organic matter in various source rock horizons of the Palaeozoic–Mesozoic basement in the Carpathian Foredeep and also the liquid (oils and condensates) and gaseous hydrocarbons accumulated in reservoirs in the area between Kraków and Ivano-Frankivs’k. The study region was divided into seven zones around oil, condensate and gas deposits for detailed determination of genetic oil – natural gas – source rock correlation. Based on source, reservoir, seal and overburden rocks, generation, expulsion, migration and accumulation of hydrocarbons and trap formation along with 1-D and 2-D modelling, two separated petroleum systems of the Palaeozoic–Mesozoic strata were established. One petroleum system occurs in the western part of the Małopolska Block, the second one in the eastern part of the Małopolska Block and western part of the Kokhanivka Zone (south-eastern Poland – western Ukraine). In addition, nine generation and expulsion areas were identified. The comparison of the two petroleum systems reveals that the western part of the Małopolska Block has considerably greater prospects for oil and gas exploration than the eastern part of the Małopolska Block and the western part of the Kokhanivka Zone.

    Opis:
    Origin of natural gas of Gorzysław, Białogard and Daszewo fields from Lower and Upper Carboniferous, and Rotliegend reservoirs on the Baltic part of the Western Pomerania was characterized by means of geochemical methods. The results of molecular analyses as well as stable carbon isotope analyses of methane, ethane, propane and carbon dioxide, stable hydrogen isotope analyses of methane and stable nitrogen isotope analyses of gaseous nitrogen enabled the determination of gas origin. Gaseous hydrocarbons and carbon dioxide originated from thermogenic processes from type III kerogen with small component of type II kerogen. At least two phases of gas generation took place: the first one at the stage of 0.6 to 0.8%, and the other one at the stage of 1.4 to 1.8% maturity of source rocks in the vitrinite reflectance scale. Gaseous hydrocarbons generated from source rocks within the Upper Carboniferous (Wesphalian) and Lower Carboniferous (Visean) strata. Nitrogen probably originated during thermocatalytic processes of organic matter transformation and partly in abiogenic processes.

    Opis:
    W pracy przeprowadzono analizę generacyjną węglowodorów w utworach karbonu w południowo-wschodniej części rowu lubelskiego za pomocą numerycznych modelowań programami BasinMod 1- i 2-D. Na podstawie wyników analiz geochemicznych wydzielono w utworach karbonu poziomy skał macierzystych. Skały macierzyste utworów karbonu rowu lubelskiego charakteryzują się dobrymi własnościami macierzystości i obecnością gazotwórczego kerogenu IlI typu. W jednowymiarowych modelowaniach numerycznych, po skalibrowaniu pomierzonych wartości dojrzałości termicznej z wielkością erozji, dokonano identyfikacji faz węglowodorowych w utworach karbonu w profilach odwiertów Komarów IG-1, Grabowiec IG-4 i Terebin IG-5. W dwuwymiarowych modelowniach wzdłuż przekroju Komarów - Terebin uzyskano przestrzenny rozkład transformacji kerogenu skał macierzystych karbonu i sumaryczne ilości wygenerowanych węglowodorów. Wykazano, że jedynie w okolicach Komarowa i Grabowca możliwe było zachowanie węglowodorów. Przeprowadzona analiza naftowa dowiodła, że intensywna erozja w paleozoiku rozformowała potencjalne pułapki złożowe, a brak regionalnego uszczelnienia mezozoicznego pozwolił na rozproszenie resztkowych ilości węglowodorów.
    In the paper authors carried out the petroleum analysis of Carboniferous strata in the south-eastern part of Lublin Trough by means of BasinMod 1- & 2-D numerical modelling. Results of geochemical analyses allowed to determine source rocks in three complexes of Carboniferous strata. Carboniferous source rocks have good petroleum potential and contain type III kerogen. In one dimensional numerical modelling, measured thermal maturity values had been calibrated of erosion quantity, it provided to identification of hydrocarbon phases in Komarów IG-1, Grabowiec IG-4 and Terebin IG-5 wells. Two dimensional modelling along Komarów - Terebin cross-section gave a spatial view on transformation ratio of kerogen and total amount of generated oil and gas. It is pointed, that hydrocarbons could be retained only in Komarów and Grabowiec area. Petroleum analyses reveal also, that intensive Paleozoic erosion ruined previously formed traps and lack of regional Mesozoic overburden caused the dispersion of residual hydrocarbons.

    Charakterystykę geochemiczną poziomów potencjalnie macierzystych utworów fliszowych jednostek alochtonicznych wschodniej części polskich Karpat Zewnętrznych wykonano dla dolnokredowych warstw wierzowskich, lgockich i spaskich, górnokredowych warstw istebniańskich i inoceramowych oraz oligoceńskich warstw menilitowych. W analizie wykorzystano wyniki badań geochemicznych 875 próbek skał z profili 11 odwiertów i 48 odsłonięć w polskiej i przygranicznej ukraińskiej części Karpat Zewnętrznych. Wyniki badań geochemicznych potwierdzają, że warstwy menilitowe są najlepszymi skałami macierzystymi. Ropotwórczy kerogen II typu jest generalnie niedojrzały lub dojrzały w fazie wczesnej "okna ropnego". Parametry kinetyczne kerogenu warstw menilitowych są zbliżone w jednostkach śląskiej i skolskiej oraz wyraźnie niższe w jednostce borysławsko-pokuckiej. Pozostałe analizowane kredowe wydzielenia litostratygraficzne lokalnie spełniają ilościowe kryterium macierzystości i mogą uzupełniać bilans węglowodorowy utworów fliszowych Karpat.
    Potential source rock horizons of the flysch cover were geochemically characterized in the eastern border area of the Polish flysch Carpathians: Lower Cretaceous Verovice, Lgota and Spas Beds, Upper Cretaceous Istebna and Inoceramian Beds as well as Oligocene Menilite Beds. The results of geochemical analyses of 875 rock samples collected from 11 boreholes and 48 outcrops in the Polish Outer Carpathians as well as from the adjacent Ukrainian were analyzed. The results indicate that Menilite Beds are the best source rocks of the Carpathian flysch cover in all analyzed tectonic units. The oil-prone Type II kerogen, deposited in marine environment of regular salinity, was proved to be usually immature or mature at an early stage of "oil window". Kinetic parameters of organic matter dispersed in the Menilite Beds, calculated based on organic sulphur content, are similar for the Silesian and Skole units and significantly lower in the Boryslav-Pokuttya Unit. The remaining lithostratigraphic divisions: Verovice, Lgota, Spas, Istebna and Inoceramian Beds, locally meet the source-rock requirements and can supplement the hydrocarbon balance of the Carpathians.
