“…The second group of samples consisted of core samples from the upper Istebna Beds, which-based on previous studies [14,29]-were found to contain mainly type III kerogen with a preference for gas and condensate generation. This is evidenced by the low HI index, ranging from 73 to 102 mg HC/g of TOC, and the generation potential.…”

The study of the source rocks was carried out with the use of various analytical methods in order to assess their generation potential and to predict the decomposition products of organic matter. The selected samples from the Menilite Beds from the Silesian and Dukla units, as well as the Istebna layers from the Silesian unit, which are classified as weak and medium source rocks in the Carpathian oil system, were examined. The generation potential and type of the products obtained from the pyrolysis of the analyzed source rocks, despite the often comparable overall content of organic matter, are significantly different. Menilite shale generated a higher abundance of hydrocarbons (alkanes, alkenes, and isoalkanes) by stage pyrolysis, which suggested that the organic matter of Menilite shale is different from the Istebna source rocks. Moreover, the thermogravimetric analysis showed a two-stage weight loss in the case of Menilite shales, while the Istebna shales were characterized by a one-stage weight loss at higher temperature. For the Istebna layers, n-alkanes from the C1–C5 range were detected as the main pyrolysis products, which proves the gas-forming type of the organic matter dispersed in these sediments. Rock-Eval analyses showed that the organic matter reached a degree of maturity corresponding to the early thermocatalytic processes (the initial oil window stage) and therefore was able to generate liquid and gaseous hydrocarbons. The comparison of the decomposition temperatures of the organic matter from the Rock-Eval and TG analyses allowed us to conclude that both measurements correlate well and can be equally used to assess the level of thermal transformations of organic matter.

The article presents the concept of petroleum systems modeling in the area with complex fold-thrust belt structure. The aim of the study was to verify the views on the influence of the overtrusting Carpathian orogen on the course of petroleum processes in the basement (Meso-Palaeozoic) formations. The project was implemented in the marginal zone of the Skole Unit (Outer Carpathians) overlapping various structural and tectonic units of the basement. The area of Rzeszów city was selected as it presents adequate complexity of the geological structure to meet assumed methodological objectives of the project and, at the same time, provides relatively vast amount of geological data available which creates a conditions for a comprehensive approach. The study was carried out using the Dynel 2D and PetroMod 2D software. The course of the structural and tectonic evolution of the area was reconstructed in 5 stages, the results of which were subsequently applied in a dynamic modeling of the petroleum systems. The modeling results made it possible to recreate and analyze the course of a complex geological processes, the effects of which are manifested, among others, by the time and amounts of generated hydrocarbons as well as the dynamics of expulsion, migration and accumulation processes. The results show the course of petroleum processes in each stage of the petroleum basin evolution, revealing a special role of thrust tectonic of Outer Carpathians on basement formations. For the adopted assumptions of the structural and tectonic evolution, the generation of hydrocarbons by Lower Palaeozoic source rocks was initiated with the overthrusting of the Carpathians. This increases the chances of their accumulation in reservoir intervals sealed by an overthrusting orogen. This is a positive premise in the context of petroleum exploration in the area.
