This paper attempts to calculate hydrocarbon reserves in productive formations of the Buyaginskaya deep drilling area. Brief information on the lithologic-stratigraphic section and tectonic structure of the Buyaginskaya structure, which is located in the western part of the Suntar uplift of the Siberian Platform, is given. Zonal and sectional features of the prospective Kharystan Vendian horizon are noted based on the history of the region’s development. The results of well testing in the intervals of occurrence of Kharystan and Osinsk productive horizons are presented. On the basis of the data obtained during the trial operation of the Kharystan productive horizon deposit, the reserves were estimated by the pressure drop method. The conclusion was made about low potential of the Kharystan horizon gas deposit within the studied area. Based on eld geophysical data, the calculation parameters for the Osinsk horizon were substantiated and oil and gas reserves were calculated using the volumetric method. It is shown by calculation that the reserves of the Buyaginskaya area can be classi ed as shallow according to the current reserves classification. The results of prospecting and exploration works in the area of the junction of the Vilyuchanskaya saddle and the Predpatomsky regional trough, showing high prospects of the Kharystan horizon in the regional plan, are presented. On the basis of the conducted studies, it is suggested that the Kharystan horizon may be distributed within the avlacogens, which are narrow and extended negative structures of the crystalline basement of northeastern strike along the northwestern and southeastern slopes of the Suntar uplift. Similar zones of oil and gas accumulation may be developed along the slopes of the Arbaisko-Sinskiy rampart. Alternative ways to monetize the available gas resources of the Buyaginskoye prospective field were proposed.

The environmental responsibility of a business implies the obligation of a business to conduct its activities in such a way as to preserve the environment for future generations. “Responsibility” also implies a willingness to pay for damage caused to the natural environment as a result of economic activities, emergencies, accidents, etc. Today, the assessment of damage resulting from accidental oil and petroleum product spills remains an urgent problem, which should cover not only environmental damage, but also economic, social and image (reputational) damage. The authors propose an approach to a comprehensive assessment of environmental and economic damage based on the analysis and comparison of various methods and methodological recommendations. The purpose of this article is to conduct a critical review of existing methods for assessing damage caused to the environment, residents and the economy of regions, and to justify the choice of the most appropriate concepts for assessing environmental and economic damage caused by a spill of petroleum products in the Black Sea. When writing the article, various methods of theoretical and empirical research were used. The theoretical significance of the work lies in the fact that the authors have developed a schematic diagram of the ecological and economic damage caused to the environment, and also proposed approaches to damage assessment, taking into account not only socioeconomic and environmental approaches, but also from the point of view of compensation for reputational losses. The practical significance of the study lies in the fact that these approaches can be used to assess the environmental and economic damage caused by the oil spill in the Black Sea in December 2024. As a result of the study, a comprehensive assessment of the damage caused was proposed, including economic damage caused to economic facilities in the form of losses and profit losses, environmental damage, image damage to the region (reputational damage). The paper suggests indicators for assessing the region’s image losses, which are based on socio-economic development strategies.

A method for working out placer placers in the permafrost zone is proposed. The method is environmentally friendly, using traditional mining technologies. The method includes working off the subterranean placers in the winter time by building an ice dam across the river bed. In the spring, the dam collapses and provides unhindered flow of water and passage of fish to spawning sites. A mathematical model of the process of freezing an ice dam is given. The necessary calculations have been made and the optimal modes of erection of an ice dam have been shown.

Cracks in the rock mass significantly affect the physical and mechanical properties of rocks, and they, in turn,must be taken into account in the planning of mining operations and construction of mining structures. There arevarious techniques for detecting cracks in the rock mass using GPR data. However, the application of these techniquesis limited by the productivity of geophysical operators, as the GPR data are mainly interpreted by them manually. Tostudy the fracturing of frozen rocks from GPR data, it is possible to use artificial neural networks (ANN), which willmake it possible to analyze GPR radarograms in order to detect discontinuities and shifts of in-phase axes of GPRsignals. A significant problem in the application of ANN is the preparation of data for training (training sample). It ispossible to create a training data set using a model of GPR section of frozen rock massif with a fracture. However,the practice of using synthetic radarograms based on the model of GPR section of frozen rock massif with a crack hasshown the need for its improvement in terms of increasing the number of rock layers, the possibility of setting inclinedboundaries, taking into account the presence of syn- and antiforms. The article describes the stages of neural networkmodel development, including the creation of a training data set, selection of architecture, training and testing of theneural network model. The validation of the ANN model showed high performance of the ANN model. Nevertheless,some drawbacks are observed in the performance of the model. The developed system will significantly reduce the timecost of GPR data interpretation. Further research will be related to improving the prediction accuracy associated withthe expansion of the training data set and development of an additional ANN model.

The GPR method is used to study the river ice cover, which provides operational information on ice thickness. The obtained data are visualized through the QGIS geoinformation system, which maps the spatial distribution of ice thickness. However, the system has disadvantages due to manual correction of the data. The study proposes the use of software to visualize the results more efficiently. This will help analyze the data more quickly, identifying areas of thick ice and ice-bottom contacts that could be potential obstacles to spring ice drift movement.

This article presents the developed physical and geological models for the GPR method, which is currently actively used in the study of mining and geological and geocryological conditions of developed alluvial deposits in the cryolithozone. The relevance of the development of GPR models is dictated by the need to determine the features of wave fields (radargrams) for reliable data interpretation. Typical models of horizontal layered structure of the upper part of the geological section (frozen loose sediments, including those with inclusion of layer ice, paleorules) of diamondiferous placers in the subarctic zone of Yakutia are considered. Computer modeling was carried out in the gprMax system using the numerical finite difference method in the time domain. Based on its results, the GPR models containing a scheme of the geological section with a description of electrophysical properties and a synthetic radargram were built. Analysis of the results of computer modeling allowed us to determine the features of the radargram structure, parameters of GPR signals in the presence of formation ice, paleorules sections. The results of the studies have shown that the developed GPR models contribute to the improvement of signal processing procedures and the development of data interpretation features in the study of the geological structure and geocryological conditions of alluvial deposits in Yakutia (using the example of “Mayat River” Anabar district) by GPR.
