In the geological structures containing crude oil and associated gases and located in areas where volcanic activity has been detected, radioactive substances and minerals are contained both in the structure of the reservoir waters and in the impurities related to the composition of the extracted crude oil. They are present during the extraction of crude oil and associated gases and affect human health and environmental safety. Radioactive elements have been detected in reservoir waters, in impurities associated with crude oil, and especially during the processing of drilling fluids (the separation of detritus sourced from geological strata from the used drilling fluid). Other radioactive elements were also detected in the areas polluted with oil and drilling waste. In order to determine the radioactivity level of crude oil originating from the area of volcanic activity of the Romanian Mountains, crude oil samples were collected from the oil field in a one-year analysis. The collected samples were analysed to determine their physical-chemical structure. The reservoir water associated with these samples and the minerals separated from the crude oil following their solvent extraction were also analysed. Radioactive elements were detected using X-ray spectrometry, and their chemical structures are also discussed.
在含有原油和伴生气体的地质结构中，以及在已探测到火山活动的地区，放射性物质和矿物质既包含在储层水的结构中，也包含在与开采的原油成分有关的杂质中。它们存在于原油和相关气体的开采过程中，影响人类健康和环境安全。在储层水、与原油有关的杂质中，特别是在钻井液的处理过程中（从使用过的钻井液中分离来自地层的碎屑），都检测到了放射性元素。在受到石油和钻井废料污染的地区还检测到了其他放射性元素。为了确定罗马尼亚山脉火山活动区原油的放射性水平，在为期一年的分析中从油田收集了原油样本。对采集的样本进行了分析，以确定其物理化学结构。此外，还分析了与这些样本相关的储油层水以及溶剂萃取后从原油中分离出来的矿物质。使用 X 射线光谱法检测了放射性元素，并讨论了它们的化学结构。

Maintenance of equipment and tools used in the overhaul of oil and gas wells depends on the reliability and durability of the tool. The recovery process of damaged wells can be accelerated by choosing the right repair equipment and following the rules and regulations in force. Cutting equipment and tools operating under high pressure and load are deformed, in the cutting zone – dispersion, i.e., a tense situation is created, and as a result of corrosion in the tribonodes, high temperatures, such as 1000–1200°C, are observed. The stress-strain state created in the shear-disintegration zone causes the formation of microcracks in the working zone of the tool, which will grow over a certain period of time. Thus, the cutting elements wear out quickly, in some cases break and quickly fail. In this case, the structural composition of the cutting elements changes, and the structural lattice in metals is destroyed, resulting in riveting. To maintain the equipment and tools used in repairs in working order, one of the important conditions is their special care and adjustment of the mode parameters. This article discusses the increase in the efficiency of the milling tool with the use of cooling agents in the process of milling various metal objects left during accidents in the wellbore. To do this, experimental data were processed, based on regression analysis, mathematical formulas were obtained that describe the temperature process depending on various regime parameters of the grinding process, and their graphical dependences were plotted. A transition from linear regression to non-linear regression has been made. The results obtained make it possible to predict the classification and design schemes of borehole cutters and the choice of composite materials for reinforcing the cutting part.

The global warming phenomenon, primarily caused by the emissions from conventional energy sources, has become a pressing concern worldwide. Greenhouse gases (GHGs), particularly carbon dioxide (CO2), emitted into the atmosphere contribute significantly to this issue. They have diverse impacts on climate, ecosystems, public health, and socio-economic systems, highlighting the need for comprehensive mitigation and adaptation strategies. To address this problem and minimize GHG emissions, renewable energy sources have emerged as the most promising alternative for power generation. These sources offer a sustainable and clean alternative to fossil fuels, mitigating climate change, reducing air pollution, and fostering energy independence. In the context of this study, a 100 kW solar photovoltaic (PV) station was proposed in Ma’an, Jordan, as a sustainable solution. The effectiveness of this PV station in mitigating GHG emissions was evaluated by comparing it to a base case involving an oil station. To perform this analysis, RETScreen software, a widely recognized tool for assessing renewable energy projects, was used to examine the environmental impact of switching from a conventional energy system to a renewable energy system. The results obtained from the analysis revealed a remarkable reduction in annual gross GHG emissions in the proposed case compared to the base case. Specifically, the emissions would be reduced by 89%, translating to an annual reduction of 49.9 tonnes of CO2. These findings underscore the significant potential of the proposed solar PV station in curbing the emissions responsible for global warming. By significantly reducing GHG emissions, the solar PV station contributes to creating a more sustainable future, aligned with the principles of environmental preservation and climate change mitigation.

For increasing the efficiency of heat transfer processes, the layer-by-layer concept of arrangement of various types of packings in column apparatuses is considered. The results of hydraulic tests of a dry and irrigated cell packing, as well as individual hydraulic tests of a mesh packing, are presented. Methods and algorithms for solving linear programming problems under “uncertainty” conditions were considered. However, in some areas of science it is often difficult or impossible to formalize the problem in an appropriate way and reduce it to a linear programming problem. In this paper, methods for solving non-linear programming problems with a vector objective function are considered. At present, the use of non-linear programming in the vast majority of real situations is reduced to linear approximation models. Along with this, at a significant non-linearity, due to its specificity or influence on the nature of the model, it is necessary to apply optimization methods that are much more complex than, for example, the simplex method. However, the importance of non-linear programming is constantly increasing. This is due to the rapidly growing knowledge of managers and specialists in the use of mathematical models designed to prepare solutions, as well as the increasing availability of computer programs for solving large-scale nonlinear problems. The analysis and studies of the hydrodynamics of a number of regular packings have shown that cell and mesh packings are promising for the implementation of the phase inversion mode. The proposed concept of intensifying heat transfer processes in column apparatuses is based on the use of layers of various packings arranged in the following order in the apparatus, type 1 – cell, type 2 – mesh. At the same time, their main geometric characteristics differ significantly from each other. However, the structure of the bulk packing is inhomogeneous, which makes it difficult to implement a stable mode of local phase inversion under these conditions. This is due to the structure of column apparatuses with bulk packing, in which there is an increased proportion of pores (porosity) near the walls of the apparatus. Porosity is very significant; it can reach up to 40%, and as a result, the local velocity near the walls exceeds the velocity in the centre of the apparatus by up to 70%. By contrast, the use of regular packing structures makes this potentially highly efficient mode technically possible.

Wyroby z tworzyw sztucznych produkowane są na skalę przemysłową już od ponad 100 lat. Ze względu na dużą różnorodność polimerów i ich właściwości wyroby z tworzyw sztucznych można spotkać w każdej dziedzinie życia. Stosunkowo niewielka gęstość większości tworzyw sztucznych sprawia, że wyroby z nich wykonane są bardzo lekkie. Polimery są odporne na działanie różnych czynników powodujących degradację wielu innych materiałów. Tworzywom z łatwością można nadać pożądany kształt, a stosując różne dodatki, można modyfikować ich właściwości. Tworzywa sztuczne można łatwo łączyć z innymi materiałami konstrukcyjnymi. Te właściwości powodują, że tworzywa sztuczne to niezwykle wszechstronne materiały, dzięki czemu możliwości ich zastosowania są praktycznie nieograniczone. Wyjątkowa wszechstronność tworzyw sztucznych sprawia, że stosuje się je w produkcji opakowań, budownictwie i konstrukcjach, transporcie, przemyśle elektrycznym i elektronicznym, rolnictwie, medycynie czy sporcie. Nie oznacza to jednak, że są niezniszczalne. Zdarza się, że różne substancje oddziałują agresywnie na polimery, powodując zmianę ich właściwości. Zmiana parametrów, fizycznych i mechanicznych, może wpłynąć bardzo niekorzystnie na możliwość stosowania polimerów w środowisku narażonym na te właśnie czynniki, prowadząc do uszkodzenia maszyn i urządzeń, jak również niekorzystnie oddziałując na środowisko naturalne i człowieka. Kompatybilność materiałowa jest bardzo ważnym czynnikiem wpływającym na trwałość, bezpieczeństwo i niezawodność stosowanych urządzeń mechanicznych. Wprowadzenie na rynek nowo opracowanych środków smarowych do nowych zastosowań lub takich środków, w których zmieniono bazy olejowe lub pakiety dodatków uszlachetniających, wymaga sprawdzenia ich współoddziaływania z materiałami konstrukcyjnymi urządzeń, w których będą one stosowane.

"The paper discusses the influence of mechanical factors on the performance and aging process of rocking machines, specifically focusing on oilfield equipment such as the downhole rod pump jack. The authors emphasize the importance of analyzing the condition and aging process of oilfield equipment to ensure reliability, safety, and efficiency in oil production processes. The mechanical factors discussed in the paper include vibrations, loads, wear, and corrosion. Vibrations can be caused by improper balance, bearing failures, or other factors, and they have a negative impact on equipment performance and can lead to breakdowns. High mechanical loads associated with raising and lowering sucker rods can cause wear and damage to the pump jack. Operating in harsh environments with sand, abrasive particles, or chemicals can also cause wear on surfaces and equipment parts. Corrosion of metal components can occur due to moisture, chemical attack, or improper storage and maintenance, leading to deterioration and breakage of equipment. The consequences of these mechanical factors on the aging of an oil pump jack include accelerated aging, decreased performance, and an increased risk of accidents. Continuous exposure to vibration, stress, wear, and corrosion accelerates the aging process, resulting in deterioration and reduced equipment life. Damage and breakdowns caused by mechanical factors lead to decreased efficiency, negatively impacting oil production processes. Moreover, insufficient maintenance and failure to address mechanical influences increase the risk of accidents, downtime, and damage to other parts of the manufacturing process. To assess the health and aging status of an oil pump jack, various analysis and diagnostic methods are used, including visual inspection, strength testing, monitoring of parameters, and non-destructive testing. Visual inspection helps identify visible damage, wear, and defects. Strength testing evaluates the reliability of pump jack parts and identifies potential issues. Monitoring parameters like vibrations, temperature, and pressure allows for detecting deviations from normal operation and preventing breakdowns. Non-destructive testing methods such as ultrasonic testing, magnetic particle testing, and radiography help identify hidden defects and damage. The authors recommend several strategies to maintain the reliability and efficiency of an oil pump jack. These strategies include implementing a preventive maintenance program with regular inspection, testing, and parts replacement based on manufacturer’s recommendations and equipment condition analysis. Determining optimal service and part replacement intervals based on historical data, monitoring results, and manufacturer’s recommendations is crucial. Additionally, utilizing more durable materials, anti-corrosion coatings, improved designs, and technologies can increase equipment resistance to mechanical stress and improve performance.

Non-destructive testing methods such as ultrasonic testing, magnetic particle testing, and radiography help identify hidden defects and damage. The authors recommend several strategies to maintain the reliability and efficiency of an oil pump jack. These strategies include implementing a preventive maintenance program with regular inspection, testing, and parts replacement based on manufacturer’s recommendations and equipment condition analysis. Determining optimal service and part replacement intervals based on historical data, monitoring results, and manufacturer’s recommendations is crucial. Additionally, utilizing more durable materials, anti-corrosion coatings, improved designs, and technologies can increase equipment resistance to mechanical stress and improve performance.

The application of a systematic approach is crucial in the design, operation, and maintenance of lifting complexes in oil and gas wells. Lifting complexes play a vital role in the extraction of hydrocarbons by facilitating the movement of drilling tools, pipes, and other equipment in and out of the wellbore. The principles of a systematic approach and their significanc in ensuring the safe and efficient functioning of lifting complexes are outlined. The systematic approach involves the integration of various elements, including technology, personnel, processes, and equipment, to achieve desired outcomes. In the context of lifting complexes, the principles of a systematic approach are applied at different stages, from the initial design to the ongoing operation and maintenance. During the design phase, a systematic approach is essential to consider all the factors that influence the lifting complex's performance. This includes assessing the well's characteristics, such as depth, pressure, and geological formations, to determine the appropriate lifting capacity and equipment requirements. Additionally, factors like safety regulations, environmental considerations, and operational efficiency are taken into account to optimize the design. Once the lifting complex is operational, the systematic approach continues to play a crucial role. It involves implementing robust management systems, including quality control, maintenance procedures, and safety protocols. Regular inspections and preventive maintenance help identify potential issues and ensure the reliability of the lifting complex. Furthermore, the systematic approach emphasizes the training and qualification of personnel involved in the operation of lifting complexes. Proper training enables operators to understand the complexities of the equipment, follow standard procedures, and respond effectively to any unexpected situations. Continuous learning and skill development programs contribute to maintaining a high level of professionalism and safety awareness. The application of a systematic approach also includes ongoing monitoring and analysis of performance indicators. This allows for the identification of areas for improvement and the implementation of corrective measures to enhance efficiency, reduce downtime, and mitigate risks. In conclusion, the systematic approach is essential for the successful operation of lifting complexes in oil and gas wells. By considering all relevant factors, integrating technology and personnel, and implementing robust management systems, the systematic approach ensures the safe, efficient, and sustainable extraction of hydrocarbons. Adhering to the principles of a systematic approach leads to optimized designs, improved performance, and increased overall effectiveness of lifting complexes in the oil and gas industry.

W artykule omówiono zaawansowanie prac w krajach UE związanych z planowaniem i budową nowych terminali pływających do odbioru skroplonego gazu ziemnego (LNG) – FSRU (ang. floating storage and regasification unit). Wdrażanie na coraz to większą skalę technologii polegającej na produkcji LNG bezpośrednio na małych wyspecjalizowanych platformach i statkach pływających na morzu umożliwia w zdecydowanie większym zakresie dywersyfikację kierunków dostaw gazu, jak i zwiększenie zdolności do jego przetransportowania tankowcami do dowolnych miejsc docelowych. W obecnej sytuacji geopolitycznej i kryzysu energetycznego działania te mają podstawowe znaczenie dla Europy. Przedstawiono charakterystykę terminali importowych LNG w krajach UE (według danych na październik 2022 r.) z uwzględnieniem ich statusu (operacyjne, w budowie, planowane) i typu (lądowe, FSRU). Aż 11 krajów członkowskich UE zamierza w okresie najbliższych 3 lat wybudować łącznie 19 nowych jednostek FSRU o rocznej przepustowości gazu po regazyfikacji większej od 0,7 mld m3, co świadczy o dużym potencjale rozwojowym tej technologii. Zaprezentowano dodatkowe usługi komercyjne oferowane przez terminale, związane między innymi z bunkrowaniem statków morskich, z przeładunkiem LNG do cystern kriogenicznych w celu dalszej dystrybucji gazu na lądzie, na obszarach nieobjętych przez sieć przesyłową. Zwrócono uwagę na działania Polski związane z budową pierwszego w kraju terminalu FSRU, w rejonie Gdańska. Projekt ten, ujęty w Strategii Bezpieczeństwa Narodowego RP, uzyskał na obecnym etapie dofinansowanie UE na opracowanie specyfikacji technicznej i na prace projektowe. Oddanie tej inwestycji przewiduje się na lata 2027/2028. Przedstawiono też działania Polski wspomagające proces dywersyfikacji zaopatrzenia w LNG poprzez zakup 8 jednostek pływających, które oprócz obsługi długoterminowego kontraktu na dostawę LNG z USA do Polski będą miały możliwość transportu LNG na innych szlakach żeglugowych.

The article presents research methods and appropriate equipment for conducting experiments, as well as the analysis of the results. Studies on the hardness of the microstructure, elastic deformation and parts and samples were carried out using hardness testers, microscopes PMT-3, MIM-8 and devices for measuring the “force-strain” characteristic. The results of the study wer used to establish the dependence of the elastic properties of Belleville springs on the heat treatment modes, while also determining the microstructure and layer depth using various research methods. Every work studying the elastic properties and measurement of the static compressive force of a spring at a given strain value has been studied theoretically. Depending on the operating conditions, disc springs can be installed singly or assembled into packages, forming an elastic element working under compression. The research materials will be used in the work to improve the tightness of straight-through valves and the durability of the shut-off assembly parts. The dependence of the spring compression force and its deformation on the geometrical parameters of the disc springs has been established. Comparison of experimental and theoretical dependences has been made. It has been established that the residual deformation of the Belleville spring after captivity has a negative effect on the tightness of the shut-off valve assembly. The influence of various technological processes and modes of thermal treatment of disc springs on their elastic properties has been studied. Practical recommendations for improving the technological process of thermal treatment of Belleville springs have been proposed. The tasks of further research and implementation of the obtained results have been determined. Search work has been carried out to improve the technology of hardening processing of parts of the shut-off unit (gate and seat) of direct-flow valves. The possibility of using accelerated nitrocarburizing in a triethanolamine medium with induction heating by high-frequency currents at a temperature range of 950°С for boriding and borochroming has been established. Samples were made from standard steel grades 40, 40Kh and 38Kh2MYuA, subjected to hardening by the considered methods, and a study was made of the hardness, depth and microstructure of the hardened layer. Research in this direction should be continued in order to study the tribological characteristics (friction coefficient and wear resistance) of hardened parts. Each operation of the spring manufacturing technology has been studied, and deviations that have a significant impact on the operation of the spring and the sealing of the shut-off valve assembly have been identified.
