The complex tectonic structure of the Sea of Okhotsk shelf, its high geodynamic activity and the presence of non-anticlinal traps in plays requires special technologies for studying the secondary filtration-volumetric parameters of reservoirs. The prediction of the location and direction of open fractures is complicated by their small size. Such fractures are frequently too small to be detected by such conventional logging or seismic instruments. The detection of fracturing by seismic methods is impossible in principle; however, some high-resolution logging tools are capable of detecting fractures under favorable circumstances. In cases where neither logging nor seismic exploration can detect fractures, geomechanical modeling can be used. Geomechanical modeling makes it possible to predict the effective porosity and permeability in the сrosshole space.Aim. To assess the geomechanical properties and secondary permeability parameters of the Sakhalin shelf reservoirs.Materials and methods. The ROXAR reservoir modeling software was used to assess the secondary filtration-volumetric parameters of the Sakhalin shelf reservoirs.Results. The modern shear stress field was revealed.

An analysis was conducted out to establish the boundaries of the Kurrachi-Dolomite formation reservoir (Jihar field, Hayan block, Palmyra fold belt). In the process of research, data from geophysical surveys of wells were used and statistical processing of the obtained data was carried out. Currently, due to the difficult situation in Syria, scientific research in this area is extremely limited.Aim. To conduct a combined processing of geophysical well data (GWD), including by using a correlation matrix, and to assess the applicability the results obtained as an express method for interpreting geophysical data and identifying the boundaries of the Kurrachine-Dolomite formation within the Hayan block and adjacent areas.Materials and methods. The well data for the empirical study was provided by the Syrian Petroleum Company. Correlation matrices were obtained between the following logging data: CAL, AC, GR, RD, RS, RHOB, and PE. This allowed a good correlation to be determined between their numerical values and the results of core studies, which were carried out to establish lithological characteristics and reservoir properties of the area under study (northwestern part of the Hayan block).Results. The processed materials made it possible to select the most effective GWD combination for identifying the boundaries and fringe zones of sediments in the Kurrachine-Dolomite formation, considered as a mega reservoir, and to identify priority development objects similar in geological structure and reservoir properties.Conclusion. The proposed method for processing field geophysical materials (construction of correlation matrices and statistical processing of geological and field data) can be used in selecting an optimal combination of GWD for establishing the reservoir boundaries of the Kurrachine-Dolomite formation, quantifying the reservoir properties, and increasing the efficiency of the Jihar field development (mega reservoir of the Hayan block).","PeriodicalId":508654,"journal":{"name":"Proceedings of higher educational establishments.

Tracer well tests were proposed in the last century as an approach for elaboration of detailed reservoir models. Such tests implied injecting weakly adsorbable tracers into an injection well followed by collection and analysis of samples in nearby production wells. The results were assumed to clarify well connectivity and inter-well hydraulic conductivity. However, practical application of these tests showed that the tracer penetrates into the production well much faster than predicted from estimates of the reservoir properties.Aim. To develop a new technique for interpreting the results of tracer well tests.Materials and methods. The process of tracer movement along a self-induced hydraulic fracture was simulated taking into account the mass transfer parameter. The developed algorithm for interpreting the results of tracer studies was tested in a deposit located in Western Siberia. The productive interval is located in the Jurassic interval of the Vasyugan Formation. An aqueous solution of thiocarbamide with a concentration of 9% was used as a tracer. Injection was carried out through injection well XX74 for 3 h. The mass of the injected tracer was 1 t. Measurements in six reacting production wells XX72, XX73, XX75, XX76, XX77, and XX78 were conducted for 75 days. During this time period, 516 samples were collected. In the first three days, 36 samples were extracted at equal time intervals; in the following two weeks, 90 samples were extracted also at equal time intervals; during the remaining days, measurements were conducted 2—3 times per week for each well. The results of the conducted studies were interpreted based on the developed methodology for all the wells.Results. A numerical and analytical solution of the problem of tracer slug movement along the fracture was obtained. Account was taken of the mass transfer between the fluids and the layer, as well as the dissipation of the tracer slug. This solution was used as the basis for a new technique for interpreting the results of tracer well tests, which allows a greater number of fracture parameters to be determined.Conclusion. The developed technique for determining the parameters of technogenic fractures was applied in practice. The presence of several fractures connecting injection and production wells is shown. It is established that the process of formation of such fractures in the reservoir is still ongoing.","PeriodicalId":508654,"journal":{"name":"Proceedings of higher educational establishments.

The mineral resource base is a strategic component of Russia’s economic security and a critical tool for strengthening the country’s position in the international arena. At the same time, economic turmoil and geopolitical tensions negatively affect the quality of resource auditing in the oil and gas and other extractive industries of the Russian Federation. This have an effect on the investment attractiveness of exploration projects, which are highly important for the continuous reproduction of the country’s mineral resource base.Aim and objectives. In order to consider the potential of mineral resource auditing for augmentation of Russia’s wealth, the following objectives were undertaken: 1) to analyze the structure and state of audit methods in Russian extractive industries; 2) to study the prospects and possibilities of applying international experience in auditing Russian extractive industries; 3) to apply new tools and approaches to optimize auditing activities in the domestic practice.Materials and methods. Both domestic and foreign research publications were reviewed, along with the reports of the Ministry of Natural Resources and the Environment of the Russian Federation and the Federal Subsoil Resources Management Agency, analytical materials and audit guides by CAAF, INTOSAI, and AFROSAI-E McKinsey. A set of general scientific and special methods Y were used: forecasting methods to assess the state and prospects of financing geological exploration in the Russian Federation; methods of comparative analysis and synthesis, induction and deduction to study the international experience of auditing in the extractive industry.Results. It is proposed to attract financial resources at various stages of geological exploration through the creation of special-purpose direct investment funds. Attention is also paid to such methods as streaming and acquisition of fixed profit margins from production activities in exchange for an advance payment, which can be applied at later stages of geological exploration.Conclusion. In order to attract investments for geological exploration of subsoil resources, Russian companies should apply new tools and approaches, as well as international best practices. In combination, this will facilitate the process of attracting funds alternative to budgetary resources, thereby diversifying the methods of financial support, and will increase the investment attractiveness of the Russian geological industry.","PeriodicalId":508654,"journal":{"name":"Proceedings of higher educational establishments.

Along with ammonites and septaries, concretions with fossils are increasingly being used as jewelry and ornamental materials in Russia. Such concretions are characterized by a wide range of sizes, as well as high decorative and technological properties, making them attractive materials for manufacturing diverse interior and jewelry products. The collection and processing of concretions with fossils was previously carried out in the Ulyanovsk region. In this paper, similar concretions found in the Republic of Kabardino-Balkaria are studied for the first time.Aim. Tо establish the stratigraphic position, mineral composition, and decorative and technological characteristics of concretions with fossils of jewelry and ornamental quality found in the Republic of Kabardino-Balkaria.Materials and methods. The collection sites of concretions with fossils and their stratigraphic position were studied. In total, 15 samples characterizing the main decorative and technological types were selected. Interior and jewelry items were manufactured from the concretions; typical samples were studied. A set of studies included the determination of luminescence (8 samples), microhardness (8 cycles), density (6 cycles), optical-petrographic analysis (3 sections), quantitative determination of mineral and chemical composition (2 samples), electron probe studies (2 samples).Results. Concretions with fossils of commercial quality are associated with lower Aptian deposits, representing marlstone with a large number of shells, mainly ammonites, and, to a lesser extent, bivalves. These comprise (wt %): calcite — 64.0, quartz — 18.7, microcline — 7.4, illite — 5.6, smectite — 2.7, kaolinite — 1.0, strontianite — 0.5, as well as traces of pyrite, apatite, albite, ilmenite, and goethite. Among the impurity elements, Sr in the amount of 0.0402 wt % is recorded.Conclusions. For the first time, the mineral and chemical (including micro-inclusions and impurity elements) composition of concretions with fossils of jewelry and ornamental quality are established. Factors determining their decorative and technological characteristics are identified. The possibility of using concretions with fossils for manufacturing a wide range of products, including jewelry, is shown. Concretions can be collected simultaneously with ammonites and septaries in river valleys without mining, thereby involving minimal costs and having no negative effect on the environment.","PeriodicalId":508654,"journal":{"name":"Proceedings of higher educational establishments.
