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:
The scheme in which the Carpathians, Carpathian Foredeep and Polish Lowland are distinguished as the hydrocarbon prospective zones was used hitherto in Poland. Good geological diagnosis of Poland area enables to distinguish the petroleum provinces in terms of basin analysis (methodology). This procedure are based on an integration of multidisciplinary geological and geophysical data with into a petroleum play concept. Results of drillings and petroleum play procedures allow to predict boundaries of petroleum provinces. Effects of basin analysis with regards to the stratigraphy of hydrocarbon-bearing areas are presented in Figure 1. All these prospective areas (Fig. 1) have been matched into five independent units (Fig. 2) which could be defined as following petroleum provinces: Pomerania, Wielkopolska, Ma3opolska, Lublin and Gdansk. These petroleum provinces are only the parts of sedimentary basins the individual development of which enabled generation, migration and preservation of hydrocarbons. Location of the above mentioned petroleum provinces is also brightly reflected on the map of crustal consolidation (Fig. 3): every province in Poland has its own individual geologic history.

Opis:
Shale gas is one of the well-known unconventional resources of natural gas all over the world. This term refers to natural gas that is trapped within shale formations. Shales are fine – grained sedimentary rocks which can be reach resources of both petroleum and natural gas. This sedimentary rocks are heavily layered and in their nature exhibit VTI velocity anisotropy behavior (Van Dok et al. 2011). This statement indicates that the world among us is not isotropic and we should not neglect this fact in our geophysical research. Anisotropy, in general is the property of the material. It can be described as the attribute of a material’s property with respect to the direction in which it is measured (Pereira & Jones 2010). There are two essential types of anisotropy: VTI and HTI. Vertical velocity layering gives rise to VTI (vertical transverse isotropy) velocity in which seismic wave velocity is faster in the horizontal direction than in the vertical one. The second type of isotropy is horizontal transverse isotropy (HTI) which causes azimuthal traveltime variations. The common mechanism for this type of anisotropy is vertical aligned fractures in an isotropic background medium (Jenner 2011.) Authors of this study focused mostly on VTI as this type of anisotropy is present in shale formations, as a result of small scaled heterogeneities from fine layering (Thomsen 1986). The VTI anisotropy can be mathematically described by using three Thomsen parameters: epsilon, delta and gamma. Epsilon is a measure of the difference between the horizontal and vertical propagation velocities for compressional waves. Gamma parameter is a measure of the difference in the horizontal and vertical propagation velocities for horizontally polarized shear waves (SH waves). Delta parameter is not easily described either mathematically or qualitatively (Pereira & Jones 2010), but it influences the anisotropy velocities in medium incidence angles. These parameters can be mathematically expressed by equations proposed by Leon Thomsen (Thomsen 1986). In this study, authors present influence of VTI anisotropy on microseismic data recorded during hydraulic fracturing of shale intervals in one of the well located in Northern Poland. Authors points out how the anisotropy affects on microseismic events location, locating them in isotropic and anisotropic velocity models with usage of TGS algorithm. Furthermore, authors indicate possible solution to estimate VTI parameters based on microseismic data. VTI anisotropy parameters plays critical role not only in case of microseismic data analysis but also in processing of active seismic data. Authors proved that VTI anisotropy present in the investigated area has strong influence on microseismic events location especially in depth. Moreover estimation of VTI anisotropy parameters based on microseismic data with usage of Thomsen equations is possible.

Ultrasonic irradiation is one of the advanced oxidation methods used in wastewater treatment. In this study, ultrasonic treatment of petroleum refinery effluent was examined. An ultrasonic homogenizator with a 20 kHz frequency and an ultrasonic bath with a 42 kHz frequency were used as a source for ultrasound. The effects of parameters such as ZnO amount, ozone saturation time, and type of ultrasound source on the degradation of petroleum refinery effluent were investigated. The degradation of petroleum refinery effluent was measured as a change in initial chemical oxygen demand (COD) and with time. According to the results, degradation increased with the addition of ZnO in an ultrasonic probe. There was also a positive effect of ozone saturation before sonication then applying ultrasound on the degradation for an ultrasonic probe. It was observed that there was no positive effect of ZnO addition and ozone saturation on degradation for an ultrasonic bath.

Opis:
The Polish part of the Baltic region is located within the contact zone between two large geological units: the Precambrian platform and the Paleozoic platform. It comprises the Polish sector of the southern Baltic Sea and the adjacent onshore part of Northern Poland (Western and Eastern Pomerania). The fundamental geological pattern is defined by the Teisseyre-Tornquist Zone, separating the East European Craton from the Paleozoic platform. As a result of exploration activity in the onshore Pomerania region, four oil fields in Cambrian sandstones, seven gas fields in Carboniferous sandstones, six gas fields in Rotliegend sandstones, and eleven oil fields within the Zechstein Main Dolomite horizon have been discovered. The petroleum play of the southern Baltic Sea region and adjacent areas must be considered separately for Eastern and Western Pomerania. In the Peribaltic Syneclise we can only take into consideration organic matter appearing in lower Paleozoic rocks but their geothermal history refers to the period from the Vendian up to the recent. The present extent of the "oil window" in the Upper Cambrian rocks is mainly restricted to the offshore area. Reservoir properties of the "gas window" Cambrian rocks are rather low due to intensive diagenetic processes. Acquisition of gas should be possible by processes of hydraulic stimulation (tight gas). Lower Paleozoic rocks rich in organic matter (Ordovician and Silurian), especially in the border zone of the EEC (Ro >>gt; 1.3%), could be an area of unconventional gas fields (shale gas). The Western Pomerania petroleum play shows two separate source rocks units. The older one embraces Carboniferous deposits with organic matter of terrestrial origin and generated gases accumulated in the Rotliegend and Carboniferous traps. The second petroleum system is located within the carbonates of the Zechstein Main Dolomite (Ca2). This is a closed system, meaning that the source rocks are at the same time the reservoirs sealed by Zechstein evaporates. Hitherto discovered hydrocarbon deposits in the Polish part of the Baltic region have confirmed good perspectives regarding oil and gas hydrocarbon zones. New, conventional and unconventional discoveries remain possible.

Opis:
In petroleum operations, the safety management and the uncertainty management have traditionally been completely separated functions. The two disciplines are to large extent based on different scientific pillars and it has been difficult to obtain an integrated approach. However, the recent introduction of risk perspectives highlighting the uncertainty component of risk has provided an improved basis for development of such an approach. By seeing risk as the two-dimensional concept covering events and consequences on the one hand side and uncertainties on the other, the content and boundaries of risk assessments are changed. The gap between the two disciplines can to large extent be bridged. The purpose of the present paper is to present and discuss an integrated framework for these disciplines and traditions, based on this risk perspective. An example is included to show the practical implications of the framework.

The paper presents studies on oil removal from soil by means of water elution with a help of shaking out the contaminants from the soil. The tests were performed on simulated soil samples contaminated with a mixture of petroleum hydrocarbons. The study consisted in recording the time influence and the number of elution cycles to remove contaminants from the soil. The samples were then subject to the determination of petroleum hydrocarbons, aliphatic hydrocarbons, and BTEX compounds (benzene, toluene, ethylbenzene, xylene). Due to adding various concentrations of petroleum into particular soil samples and applying different shaking times, it was possible to find out the impact of petroleum content and sample shaking duration on the course and possibility of petroleum substances removal by means of elution process.

Creation of rain sewer is connected with dehydration of roads and coexisting objects. The paper presents a discussion upon the issue of groundwater contamination by petroleum compounds and other pollutants from transport based on studies of groundwater within the parking lots. The study included 9 parking areas, including 7 in Bialystok, 1 in a residential area outside of Bialystok in Ignatki, and one in Kleosin. The tested waters were subject to determination of COD, total suspension, and petroleum substances expressed as a mineral oil index. The studies have shown that the concentrations of determined parameters were in most cases proportional to the larger runoffs and concentration of petroleum compounds increased with the increase of suspension. It has been shown that from part of the parking lots, the meteoric water was discharged directly into watercourses and exceeds the permissible limits regulated by the Decree.

Subject of this work was carrying out researches on removal of petroleum derivates in laboratory stripping tower. In researches model water was used, which was mixture of distilled water and petrol and diesel fuel mix in ratio of 1 to 3, next it was submitted to aeration. Repelling of petroleum derivatives was med in 4 series, starting researches from minimal concentration 0,132 µg/dm3 to 3,992 µg/dm3. Level of each concentration resulted from concentrations found in underground and superficial water based on researches made by authoress. As a result of stripping process outcomes were between 53,9 and 82,7%, lowest effects were achieved in III series – 44,8%. Observation was made, that during the process petroleum derivatives was removed gradually in III series, meanwhile in other series from the beginning high level of reduction was reached. Carried out stripping of petroleum hydrocarbons from water to air confirms relatively efficient method enabling lowering of their content to safe level. This process can be used to treatment of underground and superficial water with wide range of concentrations.

The aim of the work was to elaborate new method of wool entrapping into silica alginate beads and checking of their adsorption properties. The purpose of the present study was also to determine water bioremediation efficiency using Pseudomonas aeruginosa cells immobilized into wool entrapped into silica-alginate beads. The results of study showed that obtained capsules are stable in saline water environment. Additionally neither silica adsorbers nor wool impacted negatively on viability of bacterial strains that were entrapped into these capsules. Moreover, it should be underline that 83,01% of adsorbed engine oil has been degraded by immobilized microorganisms after 3 months of biodegradation process. The results proved that properties and non-toxic character of these beads are suitable enough to use them in purification of water from petroleum hydrocarbons.

The paper presents results of comparative tests of exhaust gases toxicity of GTD-350 turboshaft engine powered by Liquefied Petroleum Gas (LPG) and conventional JET-A1 fuel. Structure of GTD-350 engine’s test bed was discussed. Because of explosion danger of LPG vapour the test stand was arranged in the open air. Paper comprises specification of LPG supply system, gas injector’s construction and visualization of LPG injection. The supply system was based on the newly constructed pressurized injectors. Required LPG operating pressure was obtained by pressurizing LPG tank using nitrogen and LPG-flow was controlled using needle valve. A series of photographs presents shape of fuel streams for new injector supplied by JET-A1 and LPG. Photos of flame torches for multi-hole and conical type injectors fuelled by LPG are inserted as well. A comparative study of carbon monoxide, nitrogen oxides, hydrocarbons and carbon dioxide as well as oxygen concentration for GTD-350 equipped with new injectors fuelled by LPG and standard supplied by Jet-A1 was carried out. The study comprised turbocharger speed range between 40 and 80% of NTS. The exhaust gas temperature comparison for above-mentioned configuration is presented as well. All data shown in presented figures are mean of 6 measurements. All completed tests were carried out for standard GTD-350 engine combustion chamber.

The investigation revealed relatively slight changes in the pore space of the polluted samples, which were as sociated with adsorption of hydrocarbons onto the soil particles rather than with microstructural change. Introduction of non-polar organic fluid into soil pores did not cause rearrangement of the natural soil structure. Due to the initial air-dried state of the soil material, these findings pertain to unsaturated soils only. These results contribute to the crucial, but still poorly recognized problem of the engineering geology properties of organic contaminated soils.

Opis:
This paper represents the results of the investigation of soil phytotoxicity with a high level of oil pollution. The artificially contaminated soils were exposed to an oil-destroying biosurfactant based on the strains of Bacillus amyloliquefaciens and Bacillus subtilis. The main objective of the work was to evaluate the effectiveness of a consortium of microorganisms in reducing the phytotoxicity of soils with high levels of oil contamination. The determination was performed on the reactions of test organisms to the pollution of the soil environment. The test system in the experiment comprised Sorghum bicolor subsp. Drummondii, Phleum pretense, Galéga officinális, Trifolium pretense, Medicágo sativa, and Sinapis arvensis. The variety of the applied indicator plants has provided a comprehensive analysis of the results of oil destruction and allowed an assessment of the sensitivity of the seeds of each species to toxic substances.

Opis:
The peculiarities of sanitary and hygienic rationing of the oil products content in environmental components were analyzed. It was established that the general ecological situation in our country and abroad is unsatisfactory and the issue of finding modern methods of standardizing the quality of environmental components, which would cover the indicators and criteria of their composition and properties, is becoming increasingly urgent. Together, it would ensure ecologically sustainable development of the biosphere in all hierarchical levels of its organization. It was established that such an assessment system does not exist today and therefore, there is no generally accepted universal method for assessing the quality of the environmental components. For this purpose, it is necessary to develop a methodology, in particular a method of biotesting, which will provide a generalized qualitative assessment of the ecological state of the environment, without being based on the quantitative characteristics of the MPC. The possibility of applying a new method of phytotesting of soil that was artificially contaminated with different types of petrochemicals in different concentrations per unit volume of soil using flax seedlings (Linum usitatissimum L.) was investigated. The growth characteristics of the test plants grown on artificially contaminated soil with petroleum products were presented. In the course of research, the possibility of studying the effect of petrochemicals on plants directly in artificially contaminated soil was confirmed. On the basis of the analysis of the obtained results, it was found that when the soil is contaminated with oil products, the aviation fuel has a greater impact on the shoots, whereas gasoline and diesel fuel have a lower impact on the roots in lower concentrations. At higher concentrations, their depressant effect is almost equal.

Opis:
This research focuses on the bioaugmentation with Pseudomonas sp. (native) and Pseudomonas aeruginosa (commercial) for the biodegradation of total petroleum hydrocarbons (TPH) of the environmental soil samples of the AqLab laboratory in Orellana, Ecuador. Two treatments of sterilized soil (one inoculated with the native strain and the other inoculated with the commercial strain), where used for physical- -chemical analyzes as well as the degradation of TPH. They were evaluated every 20 days for a total period of 80–100 days. The native bacterium was isolated from the laboratory agglomerates in a selective culture medium specific for Pseudomonas sp. The biodegradation of the TPH exhibited a positive result after 80 and 100 days of treatment, with a reduction of 84 and 96% of initial TPH after the bacterial inoculation. The comparison between the two strains evaluated, commercial and native, showed a greater efficiency of biodegradation by the native strain isolated directly from the agglomerates, suggesting working with native strains of the place that have a greater adaptability to the contaminated environment that would ensure bioremediation processes faster and more efficient, low cost and environmentally friendly.

Opis:
Research background: The analysts of the petroleum product markets of industrial countries believe that the elasticity of demand varies at different periods, which gave rise to the hypothesis that behavioral and structural factors have changed the consumers? reaction during the last few decades, with a change in prices of petroleum products. Purpose of the article: The purpose of this article is to study the elasticity of demand and prices in order to identify changes in consumer behavior in the oil market after significant socio-economic shocks and to establish a correlation between changes in elasticity and price volatility, with the Ukrainian petroleum products market as an illustrative example. Methods: Based on the time series of the petroleum product market of Ukraine, static and dynamic models for assessing the demand elasticity were constructed. It was found that the time series of demand for petroleum products is non-stationary but then the time series of the first differences is stationary according to the extended Dickey-Fuller test; further, the fact of co-integration between time series of consumption, income, and prices was established by the Johansson test. This made it possible to construct co-integration dependence, allowing, in turn, the development of models for assessing the elasticity of demand for petroleum products, on the basis of which objective assessments of changes in consumer behavior were established. Analysis of the monthly calculation of petroleum products? price volatility during the period 2008 to 2018 has showed that the values of volatility increased abnormally in the period between the beginning of 2014 and the middle of 2015. The estimates of price and demand elasticities obtained for the two periods up to the beginning of 2014 and the second half of 2015 differ significantly from the values of the corresponding elasticities between the beginning of 2014 and the middle of 2015. Findings & Value added: Assessments of income elasticities and price elasticities for petroleum products in the Ukrainian market were obtained by three co-integration models, both short and long term, for each of the three previously defined time intervals. In one of them, characterized by a high level of price volatility conditionally referred to as a crisis, the value of elasticities differed markedly from the corresponding values in the other two periods, in particular, -0.383 for price elasticity and 1.068 for a long-term bond. In the other two periods, these were, respectively, 0.543 for price elasticity and 0.274 for long-term pre-crisis elasticity, and -0.470 for price elasticity and 0.235 for long-term post-crisis elasticity. Appropriate elasticity estimates were obtained for both the short-run and the dynamic model, for the same defined intervals. A comparison of these estimates showed the closeness of the values of elasticities for the pre-crisis and post-crisis intervals and a marked difference from the estimates of the elasticities in the crisis interval. Thus, it was found that a significant change in elasticities is accompanied by an increase in price volatility.

Opis:
Energy security is an extremely important area of every country’s activity. The management of the energy sector affects immediate functioning of the entire economy, and further the state of the natural environment. After Poland’s integration with the European Union, our country had to comply with the Community regulations. The constantly growing interdependence between states is an extremely important tendency of modern civilization. Oil and gas resources are declining, but the demand for these raw materials is not diminishing. It is estimated that there will be enough coal for some time, but burning all its resources would be a huge burden for the environment, because in this way global greenhouse gas emissions would increase even more.
