Item type:Article, Access status: Open Access , Remarks on the possibility of applying the mercury porosimetry method in petrophysical studies of rocks(Wydawnictwa AGH, 2017) Maruta, Michał; Kulinič, VitalijRock pore space is a rock mass composed of a large number of irregularly arranged and shaped pores. The diameter of the pores and their distribution and tortuosity determine the possibility of collecting and conducting reservoir fluids (Oil, Natural Gas and Saline water). Characterization of the pore space is intended to determine the distribution and size of the cavities in the rock. The characteristics of the study is based on parameters such as porosity and permeability and upon which the petrophysical static model is built. The article discusses methods of mercury porosimetry from the aspect of the exploration of the pore space of reservoir rocks for hydrocarbons. The research results of the petrophysical parameters of samples similar to typical reservoir rocks and unconventional rocks were presented. The results of capillary pressure tests in graphic form for six samples of the Inoceramian sandstone of the Skole unit were also given. The results of the petrophysical studies show the limitations of the use of the mercury porosimetry method in investigations of low reservoir parameters. Therefore, the authors have identified the next stage of research as exploring the application of the helium porosimetry method due to the chemical neutrality of helium and its small particle size.Item type:Article, Access status: Open Access , Analysis of Drill Stem Test (DST) results at Osobnica oil field, in terms of sampling of selected technology parameters(2017) Dubiel, Stanisław; Rzyczniak, Mirosław; Solecki, Marek; Maruta, MichałIn this paper results of DST tests obtained in two wells at Osobnica oil field are presented. At the same time there were analyzed and reinterpreted the conditions of these results from the selection of technological parameters and geological conditions. The results of this analysis have been developed in conclusions.Item type:Article, Access status: Open Access , Water resources and climate change - groundwater as an alternative source of water supply(Wydawnictwa AGH, 2020) Winid, Bogumiła; Chruszcz-Lipska, Katarzyna; Maruta, Michał; Solecki, MarekIn recent years, the world, including Europe, has seen a much higher incidence of extreme weather phenomena. The ongoing climatic changes have a direct impact on the condition of surface waters. Groundwater is less affected by anthropogenic pollution than surface water, since groundwater can be used in distribution systems for municipal purposes, for food purposes, sold in unit packages, and for medicinal purposes (in drinking and bathing treatments). In Poland, a country with poor water resources, the problem of water scarcity due to climate change may even increase. One solution to this problem may be the increased use of Polish groundwater resources. Hydrogeological conditions favorable to the construction of drill wells, detailed identification of available groundwater resources throughout the country and the low degree of their usage (25% on average) make it possible to increase the intake of groundwater to cover this water deficit, especially in periods of drought.Item type:Article, Access status: Open Access , Analiza właściwości zbiornikowych skał węglanowych na podstawie wyników testów RPZ i pomiarów geofizyki wiertniczej (górnojurajskie podłoże zapadliska przedkarpackiego)(2012) Dubiel, Stanisław; Zubrzycki, Adam; Maruta, MichałW artykule przedstawiono wyniki analizy statystycznej zależności przepuszczalności efektywnej (KDST) od porowatości Phi/geof.) w celu oceny zmian właściwości zbiornikowych górnojurajskich skał węglanowych, występujących w podłożu centralnej części zapadliska przedkarpackiego, w strefie Bochnia - Dębica - Mędrzechów.

Metodą analizy statystycznej wyznaczono odpowiednie równanie regresji w postaci: log KDST = -0,142 + 0,178 x Phi/geof. mogące być przydatne do prognozowania współczynnika przepuszczalności efektywnej na podstawie wielkości współczynnika porowatości dla węglanowych skał górnej jury podłoża zapadliska przedkarpackiego.Item type:Article, Access status: Open Access , Interpretation of DST test results for the identification of HC accumulation limits or boundaries in the area of the Carpathians and Carpathian Foredeep (South Poland)(2014) Dubiel, Stanisław; Rybicki, Czesław; Zubrzycki, Adam; Maruta, MichałThe result and interpretation of reservoir tests (DST) are presented in the paper. They were performed in 20 intervals of 17 production wells in years 1995-1997. These wells are located in the Central Carpathians (flysch sand beds) and mainly in the external and internal Carpathian Foredeep (the autochthonous and allochthonous Miocene thin bedded sandstones) and their substratum (mainly carbonates). The basies of the theoretical diagnoses for determining the main types of drainage zones or limits of hydrocarbon accumulations are presented in the form of a short description of the Kappa Company's programmatic procedure (Saphir 202B system). Some diagnostic diagrams for the main reservoir border models are described using the log-log method. Examples of their geological interpretation are also provided.Item type:Article, Access status: Open Access , The potential use of a Dräger X-am 8000 portable multi-gas detector for monitoring explosive gases in the area of historical oil and gas fields in the podkarpackie region(AGH University of Science and Technology Press, 2021) Maruta, MichałThe oldest oil basin in the world is located in the Polish Carpathians. Former mines, often abandoned, have become technical monuments. The growing popularity of industrial tourism in the world and in Poland attracts more and more tourists who want to »find oil« on their own. In most cases, these are abandoned crude oil and natural gas fields, with such places associated with the risk of poisoning, ignition or explosion of escaping gases from unprotected crude oil fields or borehole outlets. The article also highlights the heritage of oil mining in the Polish Carpathians and related cultural routes. The author focuses on the issue related to the occurrence of the hazard zone of hydrogen sulphide poisoning or methane explosion in the sites of old oil fields. It presents the possibility of using the Dräger X-am 8000 portable multi-gas detector as a personal device for monitoring the concentration of gases and vapours considered toxic and/or explosive, such as methane or hydrogen sulphide. It also proposes the use of the Dräger X-am 8000 multi-gas detector, which in combination with the Dräger X-site Live real-time area monitoring module, can serve as a mobile system for short- or long-term monitoring of the above-mentioned zones.Item type:Article, Access status: Open Access , Modeling of air pollution related to the “V” natural gas deposit exploitation : [abstract](Wydawnictwa AGH, 2016) Kulinič, Vitalij; Maruta, MichałExploitation of oil and gas deposits is often associated with a negative impact on the environment.Item type:Article, Access status: Open Access , Geochemical characteristics of Neogene methane-bearing lignite of the Bełchatów region(2017) Maruta, Michał; Zakrzewski, AdamCoal beds could contain various amount of methane. This attribute might be dangerous in shafts or quarrying. Among other things, the works in the coal beds, including drilling, potentially there is a risk of exceeding the methane lower explosive limit. But on the other hand it is a source of unconventional hydrocarbon accumulations. In this paper geochemical characteristic of organic matter of tertiary brown coal from central part of Poland were performed. Geochemical surveys helps to know about genesis of methane from study area. The analysed samples contain various quantity of organic carbon, from 20,74 to 71.93 wt. %. Lignite from examine samples have weak hydrocarbon potential. In tertiary sediments prevails III type of kerogen with admixture of II type of kerogen. The thermal maturity of the tertiary organic matter changes within the interval from 354 to 419 in Tmax scale. Organic matter is immature. The composition of bitumens is different in various part of study area. Elemental analysis confirm that brown coal was comprised mostly by humic-group macerals. Coal samples contain methane with mixed genesis.Item type:Article, Access status: Open Access , Analysis of drill stem testing technology of the Malm carbonate rocks of the Carpathian Foothills, in the aspect of geological research and exploration decisions(2013) Dubiel, Stanisław; Rzyczniak, Mirosław; Godula, Anna; Maruta, MichałGas-, oil- and water-bearing Upper Jurassic formations (Malm) in the area of the Carpathian Foothills are built from carbonate reservoir rocks with vuggy-fracture porosity system (or fracture-vuggy), which absolute porosity is from a few to several percent. At the end of the twentieth century DST tests provided a lot of reliable reservoir information, on which the important decisions for geological research and exploration, can be taken. The credibility of these tests results depends largely on the technology used. The paper presents the results of three selected DST tests, differing in technology, particularly with attention to the usefulness of the obtained information in explorations for hydrocarbon deposits process.Item type:Article, Access status: Open Access , Using surface geophysical methods to detect voids in the near-surface zone(Wydawnictwa AGH, 2024) Maruta, MichałThis study investigates the properties of rock formations using seismic down/up-hole measurements and electrical resistivity methods to identify structural anomalies such as voids. Surveys were conducted in four test wells in southern Poland and the analysis emphasizes the practical applications of mentioned geophysical techniques in subsurface imaging. The seismic method measured wave propagation, while electrical resistivity assessed rock resistance variability, aiding subsurface zoning. The methodology involved designing resistivity maps as depth cuts, based on seismic results. Presented velocity profiles identified weak zones, and was establishing critical geomechanical boundaries in depth, which was a basis for further resistivity geometry projecting. Resistivity measurements were conducted radially around wells, highlighting resistivity anomalies that signify risks related to subsurface void migration and changes in geomechanical properties. The analysis confirmed a general trend of increasing seismic velocity with depth, with significant deviations suggesting differences in rock quality. The resistivity method at the selected depth-cuts, mapped zones with high resistance, which was a direct indicator of the presence of changes in the rock mass. These findings are crucial for planning safe earthworks, soil stabilization, and environmental monitoring, particularly in subsidence-prone areas. Future research may enhance anomaly detection and monitor changes in rock mass properties over time. Combining seismic velocity profiling and resistivity measurements proves effective in identifying subsurface structures, which is vital for risk mitigation in engineering and environmental projects.
