Taking into account the world and domestic experience of studying the ontogenesis of lithospheric hydrogen a combination of coupled hydrochemical, geochemical and microbiological factors of the accumulation of this natural gas together with methane in the terrigenous formations of the sedimentary cover is justified. It is predicted that various hydrochemical and microbiological processes that cause the development of carbon dioxide and sulfate corrosion of engineering structures, as well as cement of reservoir rocks and tires, can occur together with methane at industrial facilities of underground storage of hydrogen. The risks of reducing the volume of injected hydrogen in underground storage in addition to diffusion losses can be associated with geobiological factors, including the conversion of hydrogen into CH4 and H2S due to microbial activity, chemical interaction of hydrogen with minerals of reservoirs and tires, accompanied by changes in filtration-capacity and geomechanical properties, hydrogen embrittlement of metal structures of ground and underground well equipment.

The article is devoted to defining the essence of facility-tourism as a promising area within the tourism industry, which can potentially increase the attractiveness of Ukraine for foreign tourists and become a powerful competitive center in the redistribution of international tourist flows. The need to improve existing approaches to understanding industrial tourism (common term) has been demonstrated because it does not take into account the full range of opportunities associated with visiting abandoned cities, towns and buildings, existing and abandoned machines and industrial facilities, land and underground. engineering structures, exclusion zones and other objects of anthropogenic activity. The article proves that having an extraordinary technological, industrial, engineering potential, Ukraine can create hundreds of additional facilities that will have not only practical significance, but also financial and economic effect. In addition, the launch of facility-tourism in Ukraine will create additional opportunities for the development of related areas of services - hotel and restaurant business, museums, transport, etc., and will be the basis for creating new jobs, which is certainly important for modern Ukraine. Special attention in the article to the define the prospects and place of international facility-tourism in the tourism industry of Ukraine. The method of testing hypotheses proved that its initiation will certainly have a positive effect. The authors also paid attention to the development of the industry during the pandemic. It was proved that this type of tourism can fully work even in conditions of quarantine restrictions due to the possibility of organizing facility tours for small groups of foreign nationals.

During the past few years particular attention has been paid to the protection of metal parts of engineering structures of all kinds against corrosion. The problem of protecting metal structures against deterioration is now recognised as of primary concern both to users and to manufacturers. Corrosion prevention is an economic problem and its cost must be based on the cost of preventative measures compared with the loss directly and indirectly due to deterioration. In those sections of industry in which marked advances have occurred in corrosion prevention, the advances can be seen to be the result of close co-operation between the laboratory, manufacturers and users.

The geological strength index (GSI) is one of the most exceptional rock mass classification system which is used to evaluate very weak and highly jointed rock mass by different approaches and related to rock mass geomechanical properties including generalized Hoek & Brown constants, deformation modulus, strength properties, and Poisson’s ratio for an appropriate design of tunnels, caverns, and other engineering structures. The distinctiveness of this system over the rock mass rating (RMR), Q-system, and other empirical methods is as follows: it utilized field observations, blockiness of rock mass, and surface joint characteristics during the evaluation process of rock mass and efficiently espoused as an empirical tool for estimation of geomechanical properties of rock mass required for pre-post stability of engineering structures using numerical modeling. This study presents the review of the 19 years of research studies conducted by different researchers about the GSI in a systematic way, i.e., origination, modifications, applications, and limitations. Furthermore, this study will provide a better understanding to field professionals (geologists, mining and civil engineers) about the qualitative and quantitative estimation of the GSI and its application as an empirical estimating tool for an appropriate design of engineering structures in rock mass environments.

The topic of the article examines the special connection between an industrial enterprise and the urbanistic environment, taking into account certain features of the location of an enterprise in an urban planning environment, as well as the corresponding factors of the architectural and construction scheme of modernization of production to understand the modern process of reconstruction and renovation of industrial facilities in a historical context. In search of figurative plastic stylistic expressiveness, architects in the 1920s and 1940s drew attention to engineering structures, machines and units were placed outside, which already at that time became a visual carrier of iconic-shaped symbols of the aesthetics of industrial culture. Subsequently, during the period of new experimentation in the 60s and 70s, the volumes of the engineering infrastructure were included in the structure of the volumetric-spatial solution of the production environment as an element of compositional construction based on block-modules given by the technology. The revival of the modern synthesis of arts is talentedly embodied in the metallurgical enterprise "Interpipe": frescoes, volumetric compositions of the modern Danish artist - Olafur Eliasson have formed a modern industrial enterprise where almost classical heritage of the experimental period of the 60s-early 70s remained the basis and

Laboratory studies of the geomechanical properties of rocks are an important and integral part in building a geomechanical model. This study resulted in a set of data on geomechanical and elastic properties of the rocks that compose the lower part of the Middle Carboniferous section of the Ivinskoye oilfield (Russia). Relationships between various elastic parameters were also established. The distribution of geomechanical properties correlates with structural/textural features of the rocks under study and their lithological type. This information can be used as a basis for geomechanical modeling and in preparation for hydraulic fracturing. Keywords: geomechanics; elastic properties; carbonate rock; laboratory core studies.

Geologic CO2 storage site selection requires reservoir, seal, and overburden investigation to prevent injection- and storage-related risks. Three-dimensional geomechanical modeling and flow simulation are crucial to evaluate these mechanical-failure-related consequences; however, the model input parameters are limited and challenging to estimate. This study focuses on geomechanical properties extracted from seismic-derived elastic property cubes. The studied reservoirs (Middle Jurassic Sognefjord, Fensfjord, and Krossfjord formation sandstones) and cap rocks (Heather and Draupne formation shales) are located in the Smeaheia area, northern North Sea, and are evaluated for a potential CO2 storage site. From the elastic property cubes, i.e., acoustic impedance, P- to S-wave velocity ratio, and bulk density, we obtained geomechanical property cubes of Young's modulus, Poisson's ratio, shear modulus, lambda-rho, and mu-rho. Petrophysical property cubes such as porosity and shale volume were also available and were extracted from the elastic property cubes using deterministic methods. We evaluated the geomechanical properties to observe their relationship with depth, compaction/cementation, and petrophysical properties to characterize the cap and reservoir rocks. We found good coherence between the geomechanical and petrophysical properties and their relationship with compaction as a function of depth. The brittleness analyses using elastic property crossplots reveal that both the cap and reservoir rocks are mainly ductile to less ductile, posing lower fracturing risk during CO2 injection. This also indicates lower risks of associated microseismic and possible CO2 leakage.
