The oil industry is sensitive to taxation like no other industry, and all because resource taxes alone account for about 60% of the cost of oil. Over the past 16 years, the tax system of the oil industry has undergone a large number of changes and is still at the reform stage. The implementation of tax reform in the fuel and energy complex was the most important stage in the transformation of Russian legislation. In 2019, a new tax regime appeared - the additional income tax (AIT). In 2021, there was an expansion of the scope of application of AIT. Due to the fact that an increasing number of fields are switching to the AIT, the topic is becoming even more relevant. The main objective of the new tax is to stimulate production and stop providing targeted benefits for the mineral extraction tax (MET), which do not allow taking into account the profitability of production at specific deposits. The article discusses the problems of taxation in the oil and gas industry, provides a description of the current tax regimes, and also presents a solution to the issue of distributing AIT among operating facilities, since today there is no specific method for distributing AIT and this has become a serious challenge for many oil and gas companies that have switched to tax on additional income. In this regard, the authors examined several options for distributing AIT for development objects and found an approach for distributing taxes that allows reducing labor costs, as well as improving technical and economic calculations.

Review of data on the composition of the subsalt sedimentary sections of the Pre-Caspian basin

DOI:
10.24887/0028-2448-2024-1-16-23

The work examines the main patterns of the structure of the subsalt section of the Pre-Caspian Data on the structure of each of the sides of the depression was collected and updated, and the stratigraphic reference of the sediments was clarified, taking into account modern knowledge about the existing stratigraphic scheme of the region. Based on the analysis of numerous published and archival stock materials, schematic lithological-stratigraphic columns were constructed for the northwestern, northern, eastern, southern side zones of the depression and the zone of the Astrakhan carbonate massif, which reflect the main patterns of the structure of the sections of the given zones, and also mark their reflecting seismic horizons. Areas with active carbonate accumulation are identified, which occurred in stages during the time interval from the Middle-Late Devonian to the Early Permian. At the same time, the earliest carbonates are identified on the northwestern, northern and eastern sides of the depression and on the Astrakhan massif. Within the southern marginal zone, excluding the Tengiz-Kashagan subzone, until the end of the Early Carboniferous, terrigenous sedimentation prevailed. Moreover, predominantly terrigenous sediments accumulated within a limited area of the Matken-Ushmola subzone in the south of the basin.

The varying degrees of knowledge, existing disagreements in regional stratigraphic schemes, the degree of completeness and reliability of the identified stratigraphic units are questionable, and therefore additional core, lithological, paleontological and stratigraphic studies are needed in the future. It is quite possible to use isotope geochronology methods, especially in the southern and southern-eastern parts of the Pre-Caspian basin, where there are different views on the structure and origin of the South Emba zone. The northwestern section also requires additional research, clarification of ages and correlation of horizons.

A new look at the deep structure and oil and gas potential of the Pre-Caspian basin based on the results of the first phase of the Eurasia project

DOI:
10.24887/0028-2448-2024-1-24-30

The Pre-Caspian megabasin is a large oil and gas basin with a unique geological structure. However, the region remains poorly studied, with uneven drilling and seismic sections limited in length. The presence of thick salt strata and morphological features create difficulties during geological exploration, their interpretation and forecasting of hydrocarbon potential. The results of the study allowed authors to establish the complex structure of the depression, including the Archean and Baikal basement. The study of geophysical materials, especially seismic data, makes it possible to revise the concept of the structure and history of the development of the southeastern margin of the Pre-Caspian depression. Within the limits of the North Caspian and Temir uplifts of the depression, numerous protrusions of the foundation have been revealed, which are overlain by Paleozoic sedimentary rocks. These protrusions contain promising traps for hydrocarbons at depths up to 78 km. The block structure of the foundation determines the features of the subsalt sedimentary complex of the basin. The study of the Pre-Caspian basin showed the presence of isometric uplifts, such as Kashagan and Tengiz, as well as a system of narrow uplifts of the eastern side zone. As a result of modeling the migration of oil and gas from source strata, it was revealed that about 4,70 trillion tons of hydrocarbon fluids emigrated, mainly liquid. The analysis of structural maps has shown the possibility of migration and filling of potential traps in the Lower Permian, Visean-Bashkir and French-Famen oil and gas complexes. The obtained simulation results made it possible to successfully reproduce the main deposits in the studied area, reflecting real data. The deposits in the west of the depression are characterized by a high content of gaseous hydrocarbons, while in the east the liquid fraction predominates, corresponding to the more oil potential of the eastern side of the Pre-Caspian depression. In the central part of the depression, exclusively gas accumulations are formed associated with the migration of gas from the oil and gas source strata. In the northern side zone, there is an increased content of liquid components. An increased content of gaseous hydrocarbons was detected on the Astrakhan platform. In the south of the Caspian sea, accumulations of hydrocarbons are observed in all the complexes under consideration. Modeling also showed the presence of new promising zones at various stratigraphic levels. Particular attention is paid to the formation of gas condensate accumulations in the central part of the depression.

Methods for predicting heat flow during 3D basin modeling on the example of the Pre-Caspian depression

DOI:
10.24887/0028-2448-2024-1-32-36

The 3D basin modeling is fraught with a number of uncertainties, one of them being the correct reconstruction of geothermal history. The article examines the major issues that complicate the forecasting as well as the methods used to overcome them using the Pre-Caspian depression as an example. The purpose of the work is to enhance the accuracy of assessing the thermal field variations during the evolution of the Pre-Caspian depression. The account of the temperature measurements of the Earths surface from spacecraft can reduce forecast uncertainties. Repeated temperature measurements over a sufficiently close network from different spacecraft provide more information. However, obtaining reliable data characterizing exactly the endogenous component of the thermal field is associated with certain difficulties. Combining the results of the Earth's thermal field surface measurements with measured data from temperature surveys performed in deep wells made it possible to obtain a 3D vertical gradient model for the thermal field. The models evolution over time was traced using geothermal modeling in Temis Flow software. The modeling outputs were surface temperature and heat flow distribution maps updated based on actual well data. The results obtained demonstrate a non-uniform temperature distribution in the sedimentary cover due to halokinesis, which affects the distribution of the source rock catagenetic alteration degree: catagenetic maturity is lower under thick salt diapirs than in the salt thinning zones. The data obtained allow a more accurate assessment of potential hydrocarbon fluid generation volumes. In places at the same depth, sediments beneath the diapirs are transformed to gradation MK3-MK4, and in the interdome zone to MK5-AK1.

The influence of the processes of formation of authigenic clayey mineral deposits on the filtration-capacitive properties of terrigenous rocks

DOI:
10.24887/0028-2448-2024-1-37-40

Studying the influence of formation of authigenic clayey mineral deposits on the physical properties of rocks is a current issue today. The lithological features of reservoirs predetermine their physical properties, the main of which are filtration-capacitance characteristics and are divided into primary and secondary. The primary factors include the granulometric composition of the clastic part of rocks and structural characteristics (sorting, grain size). Secondary factors include the nature of compaction of sedimentary rocks (intergranular contacts) and superimposed transformations of rock fragments and cement, among which authigenic mineral formation of clay minerals is distinguished. Clay minerals, which are found in cement of terrigenous rocks, have a direct impact on the reservoir properties. The purpose of the work is to study the interdependence between reservoir properties of the rock and the composition of clay minerals and their forms of selection. The object of the study were core samples of the , , layers. The analysis of lithological, petrophysical, petrographic, mineral and geochemical data was carried out in the work. The research results showed that clay cement simultaneously with stage changes underwent superimposed epigenetic processes, which led to the transformation of the mineral composition of clay particles (kaolinization, chloritization and hydromica of cement), a change in the structural characteristics of clays and the emergence of new structural polytype modification. The comprehensive study made it possible to establish the authigenic nature of kaolinite and chlorite, as well as staging of their formation. Late generation kaolinite is represented by large, thick particles resembling pseudohexagonal crystals in their shape. The chlorite component of an earlier generation in the most cases directly contacts the surface of a detrital grain, while flakes of hidromicaceous composition are the latest in generation. The authigenic clay formation in the pores of terrigenous peservoirs leads to deterioration of reservoir properties. It should be noted that an increase in the hydromicaceous and, to a greater extent, mixed-layer component in the stone leads to a complication of the structure of the pore space and to a noticeable decrease in reservoir properties. Secondary mineral formation is an indicator for identifying reservoir zones with increased filtration-capacitance properties for rocks of various facies complexes.

Quantitative assessment of bitumen content in oil deposits of the Osinsky productive horizon of Eastern Siberia

DOI:
10.24887/0028-2448-2024-1-42-46

Natural bitumen refers to organically formed minerals with a primary hydrocarbon basis, which are confined to the subsurface in viscous, visco-plastic and solid states. Such substances form a wide range of compounds from high-carbon differences to individual classes of hydrocarbons containing asphalt-resinous components and metals: malt, asphalts, asphaltites and other analogs. The Osinsky productive horizon of the Lower Cambrian (productive formation B1) in the Irkutsk region is one of the main ones for increasing the hydrocarbon resource base in Rosneft's assets. At present, nine oil deposits have been put in the State Register of Reserves. Production of bitumen and high-viscosity oil in the future will allow optimizing the development system with the most complete recovery of hydrocarbons at maximum economic profitability. In most cases oil of the Osinsky horizon can be classified as light, but at the same time there is a widespread development of very viscous to oxidized bitumen in the sediments. The presence of bitumen and viscous oils is due to the fact that the carbonate sediments under consideration are ancient (low Lower Cambrian) and are characterized by a complex structure. The transformation of sediments considering the long history of formation caused a highness of reservoir properties anisotropy, and also led to the reformation of hydrocarbon accumulations. The proportion of bitumen in the rock is often significant and often affects the assessment of reservoir properties. The article presents the methodology of bitumen estimation in the carbonate reservoirs of the Osinsky productive horizon based on well logging data. The quantitative content of bitumen in the void space is determined by the dependence of pyrolysis data on the transverse relaxation rate according to nuclear magnetic logging data. Consideration of bituminosity in the void space allows estimating its volume by section and by area. For this reason, quantitative assessment of bitumen in open oil deposits was performed.

Increasing the efficiency of acid treatment technology in Riphean sediments of Eastern Siberia

DOI:
10.24887/0028-2448-2024-1-48-53

The efficiency of bottomhole zone hydrochloric acid treatment depends on geological and physical characteristics of the productive formation (formation temperature, fracturing, proximity of water-oil and gas-oil contacts, etc.), the degree of rock dissolution during interaction with acid composition, and formation coverage. To assess the influence of these parameters, an integrated approach is required when planning the design of acid treatment of horizontal wells. In order to improve the efficiency of acid treatment in the conditions of Riphean deposits of the Yurubcheno-Tokhomskoye oilfield, represented by low-temperature dolomitized rocks, a set of analytical and laboratory studies was carried out to determine the optimal treatment technology. The main features of this object are: low share of working intervals in relation to the total length of the open wellbore of production wells, low reservoir temperature, fractured dolomitized reservoir, risks of acid breakthrough into water- and gas-saturated parts of the deposit. In the course of physico-chemical experiments, the prospect of increasing the efficiency of exposure with an acid composition based on 24% HCl, modified by a mutual solvent, which provides an increase in the rate of reaction of the composition with the rock of the Riphean object of the Yurubcheno-Tokhomskoye field, was shown. In order to evaluate the effect of the modified acid composition on the rock matrix, a filtration experiment was carried out, the results of which revealed the formation of a highly conductive dissolution channel, which confirms the effectiveness of the composition. The horizontal well treatment design adapted to the conditions of the Riphean object was developed. Pilot tests of acid treatment technology with the use of modified composition were carried out; the results of the research and the technology effectiveness were confirmed.

Technology-induced mineral formation in carbonate rocks-reservoirs of heavy hydrocarbons under laboratory high-temperature filtration experiments

DOI:
10.24887/0028-2448-2024-1-60-64

One of the most effective thermal methods for oil recovery enhancement in case of high-viscosity oil reservoirs is the technology of steam cyclic stimulation of the well. Using this method, RITEK LLC was able to put into development previously unprofitable high-viscosity oil reservoir in the Volga-Ural oil and gas bearing region. However, sequential laboratory studies of physico-chemical processes occurring in carbonate rock during steam cyclic treatment of the reservoir at temperatures of 250-350C allowed to identify processes that affect the reduction of rock permeability, which leads to a decrease in the treatment efficiency. In the course of determining the relative phase permeability in the stationary mode during the filtration of oil and water, a significant irreversible decrease in the permeability of the core model was noted. Extended studies of samples of rock-reservoirs of high-viscosity oils allowed to identify a series of sequential, interrelated processes that underlie the reduction of permeability. Such a process is partial or complete destruction of the microcrystalline calcite rim with subsequent colmatation, local formation of organic hydrophobic films in the pore space, as well as the formation of needle-like technology-induced crystals at high temperatures. This study is devoted to the study of newly formed minerals as a result of high-temperature filtration experiments on the core model and hydrothermal impact on the rock crumb in reservoir conditions. The study of the rock was carried out by a number of lithological-mineralogical methods: petrographic study of thin sections, X-ray phase analysis, scanning electron microscopy, transmission electron microscopy with electron diffraction, micro-X-ray spectral analysis. According to the results of the study, it was found that during the hydrothermal impact on carbonate rocks in the presence of quartz, minerals of the group of calcium hydrosilicates (tobermorite, xonotlite, etc.) are formed, which fill the void space and significantly reduce the pore space and filtration ability of the rock, which worsens the filtration of fluids in the reservoir. The obtained results will allow to reasonably approach the development of ways to prevent the filling of the void space with newly formed crystals during the steam cyclic stimulation, which will lead to an increase in oil recovery.

Sensitivity analysis of hydraulic fracture direction in the development system for the hard-to-recover reserves based on control of the formation stress state

DOI:
10.24887/0028-2448-2024-1-54-59

The article considers a development system based on controlling the formation stress state. This development system combines the advantages of using horizontal wells with fractures oriented across the horizontal wellbore for fluid production, and horizontal wells with longitudinal fractures for injection of displacement agent. The required orientation is achieved by controlling the direction of fracture growth by controlling the stress state of the formation. The mechanism that allows to control the direction of hydraulic fractures is based on the influence of the pore pressure gradient on the local stress state of the rock mass. However, for the successful implementation of a development system, it is necessary to analyze its stability to a number of geological, geomechanical and technological parameters. A simulator for calculating the direction of initiation and growth of fracture was used as an analysis tool. This simulator is based on a physical and mathematical model of the stressed state of a formation with arbitrarily oriented fractures and a non-uniform pressure field. The model is based on the theory of poroelasticity using the maximum tensile stress criterion to determine the direction of formation and calculate the trajectory of a growing crack. It is shown that the development system is most sensitive to those parameters that are responsible for the energy of the stressed state in the formation. Such parameters include, in particular, the initial stress contrast, as well as the parameters of reservoir thickness and Biot constant. The direction of regional stress does not directly relate to the energy state of the formation, but can affect the energy of the hydraulic fracture system depending on their direction. The permeability of the reservoir determines the time interval in which stress reorientation occurs, the propagation pressure of a hydraulic fracture determines the degree of fracture trajectory deviation of the from the original direction. With the observed deterioration in the reservoir properties of fields, the implementation of this development system with transverse fractures will improve the efficiency of development of hard-to-recover reserves.

The perspectives of using natural phenomena for the construction of production facilities

DOI:
10.24887/0028-2448-2024-1-65-69

Over the last decades, humankind has been searching for new ways to improve the effectiveness of civilization. Firstly, the research and production community is learning to adopt ideas from nature for new technological solutions that allow improving efficiency of current production processes. Secondly, it is increasingly trying to manage natural phenomena in balanced manner.. The Presidential Decree "On the development of nature-like technologies in the Russian Federation" provides a substantial push towards this field. For the first time the various issues surrounding the comprehension and replication of natural systems, as well as their efficient management mainly pertaining to energy systems are presented as one, unified approach. Under the direction of nature-like technologies, first of all, one understands the task of studying and reproducing individual samples of living nature. This paper proposes to broaden the range of subjects studied to include macrosystems - components of an ecotope. This would address the specific need for efficient management of the existing ecotope or for replicating natural phenomena in order to achieve a desired outcome. One possible directional outcome of applying natural phenomena is a decrease in the expenses related to constructing and maintaining objects and production facilities. In this context, the paper considers examples of controlling the following natural phenomena: wind effects, hydrological processes, including lithodynamics, control of permafrost. The paper also considers examples of application of various microbiological technologies in construction. Both examples of directed impact and examples of minimizing negative impacts from the development of undesirable phenomena are considered. Some of the given examples relate to natural phenomena that have the most significant impact on construction objects during economic activities in the Arctic region.

On the possibility of optimizing the use of associated petroleum gas at the facilities of Samaraneftegas JSC

DOI:
10.24887/0028-2448-2024-1-70-74

The article considers approaches to the analysis and evaluation of the possibility of effective use of associated petroleum gas (APG) at the fields of the Samara region. A selection of the observed objects of Samaraneftegas JSC was carried out to assess APG in flares and check the characteristic indicators of their condition for evaluation as a solution for the possible development of more intensive use of APG. The quantitative criterion for selecting a cluster of candidate facilities was limited by intersection of a certain volume of gas flaring (at least 5 mln m3 per year) and a low degree of utilization of the facility in question as a whole (up to 75-77%). For a selected group of facilities, each of which, for the purpose of depersonalization, is called a licensed area, characterized by a serial number and gas flaring volume, calculations were made to model the relative unit costs of capital investments for a number of classical and often used in practice optimization measures use of APG. It is noted that the wells production in the Volga region quite often is sulfurous and hydrogen sulfide-containing oil, which objectively reduces the profitability of using petroleum gas in local areas of oil fields. The need for a detailed study of the use of APG resources in relation to the conditions of the Volga region is emphasized, in order to take into account, in each specific case, the specifics of the state of the oilfield infrastructure, gas quality, and the need for energy of one kind or another.

Experimental studies of the heterogeneity of the response of petroleum dispersed systems to the use of solvents

DOI:
10.24887/0028-2448-2024-1-75-79

As a rule, the effectiveness of an oil production technology based on chemical reagents is usually associated with the composition of the reagent and the technological parameters of injection. However, when developing new technologies, it is also necessary to take into account the heterogeneity of the response of the dispersed oil system to external influences. It is known that the composition and properties of oil, especially at the late stage of oil field development, are largely determined by the continuous change in geological and physical conditions during the development process. Temperature and pressure affect the stability of asphaltenes in the petroleum dispersed system and, accordingly, the physicochemical characteristics of the produced oil. Despite a fairly large amount of research into the interaction of oil and various chemical reagents, the question remains to what extent the results obtained are universal.

In the article, based on experimental laboratory studies of the influence of solvents in various concentrations on changes in the viscosity-temperature characteristics of oil samples taken from wells of one deposit, differences in their rheological behavior were identified and the intervals of the most significant changes were determined. The results obtained show the need to expand research into the heterogeneity of the response of petroleum dispersed systems to external influences and the potential for increasing the efficiency of technologies for extracting hard-to-recover oil reserves using solvents. Considering that during field development the nature of changes in the composition and properties of oil is dynamic and complex, an in-depth study of the processes occurring during the interaction of oil and chemical reagents is of high scientific and practical significance.

Study of the influence of graphene oxide additives on the physical and mechanical properties of cement stone

DOI:
10.24887/0028-2448-2024-1-80-83

The article presents the results of the study of graphene oxide additives influence on the physical and mechanical properties of cement stone. The prerequisite for the study was the use of carbon nanomaterials, in particular graphene and graphene oxide, for cement slurry, since these substances have unique physical and mechanical characteristics and determine the rheological properties of liquids at various temperatures and pressures. The authors present the result of experimental studies including graphene oxides during the hardening of the cement mixture, the strength of cement stone, the rheological properties of cement slurry, the properties of the adhesive action of the metal cement pair, and the structure of cement stone. PCT-I-G cement was used as the basis of the cement mixture. RG-T1 graphene oxide nanoplates were used as a additive. Methods of experimental studies of cement slurry properties correspond to national standards GOST 310.1-76 GOST 310.3-76, GOST 310.1481. The setting time of the cement paste is carried out using the VIKA IV-2 device according to TU 25-04.2550-80. The rheological properties of cement slurries were measured using an OFITE 900 rotational viscometer. It has been established that the addition of graphene oxide in an amount of 0.5-1.5% leads to a significant reduction in the setting time of the cement slurry compared to cement without additives. It has been experimentally shown that an increase in the proportion of graphene oxide leads to an increase in the tensile strength of cement stone. The influence of graphene oxide components on the rheological properties of cement slurry was also discovered, which is manifested in a decrease in dynamic shear stress and effective viscosity at a shear rate of 300 s-1. Using electron microscopic methods, it has been established that the development of graphene oxide has a significant impact on the structure of cement stone, changing its characteristics and porosity. These results indicate the potential of using graphene oxide to improve the properties of cement materials.

Review of international practices in diagnostics and accidents forecasting for ESP units

DOI:
10.24887/0028-2448-2024-1-84-89

To date computer technologies are being actively introduced into the industry. One of the urgent issues at the moment is a proactive approach to the prevention of equipment failures. The purpose of this paper is a review of existing approaches to diagnostics and failures prediction of electric submersible pumps (ESP) units. A literature review was conducted in the domain of diagnostics and forecasting of ESP malfunctions. There are 4 main approaches observed: deterministic, expert-based, data-based, and hybrid. A deterministic approach uses functional or analytical dependencies, an expert approach is based on the available knowledge base, which is used in the form of patterns interpreted by specialists, a data-based approach identifies existing patterns based on the historical archive of data, and hybrid approach may include various options for combining main approaches. For each group examples, features and results are provided where possible. Applicability and limitations of each category are given. As a result of literature analysis, the advantages and disadvantages of existing approaches are established. Main advantages of deterministic approaches are interpretability and non-dependence on historical data. Expert rules are mainly used in the diagnosis of the current state without forecasting, unlike fuzzy logic approaches. The effectiveness of this approach depends on the quality of the applied rules and data. The main advantage of the data-based approach is the absence of detailed physical modeling of systems or processes. The main disadvantage is the dependence on the volume and quality of historical data. A promising direction is combined approaches that include several models, thereby adopting the advantages of each one of them.

Tasks of forming a parametric system for ensuring the integrated safety of tank farms of marine terminals

DOI:
10.24887/0028-2448-2024-1-90-97

The construction and active operation of technically complex and critical industrial facilities, the consequences of accidents on which are extremely significant, requires ensuring the maximum level of safety. At the same time, any commercial activity, including the activities of fuel and energy complex facilities, requires managing and limiting costs and ensuring a certain level of profitability. The article is aimed at setting the task of creating a parametric system for ensuring the integrated safety of tank farms at marine oil terminals, allowing to reduce the risk of an emergency or emergency situation to the minimum acceptable level, while the cost of such a parametric system should tend to the minimum. A marine terminal with a tank farm is a strategic facility, both from the point of view of the countrys energy security and from the point of view of the scale of damage that could potentially occur in the event of an accident or emergency situation there. In recent years, the concept of integrated security has become actively used as a generalization of the entire set of measures that ensure the operational, reliable and safe condition of a particular object. The article proposes an approach to the formation of a parametric system for ensuring the integrated safety of tank farms at sea oil terminals. The proposed methodology is based on an integrated approach to the term safety, which is implemented in the legislation on technical regulation of Russia. For each security parameter, it is proposed to establish appropriate criteria that make it possible to quantify and compare the actual level of security for this parameter with the acceptable level of security. The article proposes such parametric criteria for the tank farm of a marine oil terminal.

Experience of the conditions monitoring of grounding devices on oil and oil product pipelines

DOI:
10.24887/0028-2448-2024-1-98-103

By measuring the resistance to electric current spreading into the ground from large-sized terminals as an example, we have presented our results when analyzing the possibility to perform measurements for various electrodes installation designs in field conditions. Specific features of performing work during the inspection of the existing on-site facilities of main oil and oil product pipelines we have described. Including taking into account the shape of large-area grounding devices, their location in close areas with various terrain features, in the presence of long pipelines, communication lines (CLs), power transmission lines (PTLs), forests, etc. For certain cases, e.g., for terminals of facilities with a size of about 100 m, that are located on loams, we have justified the parameters of a two-beam design for measuring the spreading resistance, which ensures the required measurement accuracy and the inspection efficiency in field conditions. Our theoretical assessment of the nature of changes in the measured ground resistance at different distances between the grounding terminals support point and the measuring electrodes qualitatively coincides with the results obtained in field conditions. We have described the cases that exemplify the possibility of expanding the application scope of the results obtained to facilities located in areas with a rugged topography. We have also demonstrated that the basic ratios between the distances, at which it is advisable to install the electrodes in case of a double-beam measurement design, can also be used under certain conditions when inspecting the state of grounding systems of main oil and oil product pipelines facilities with overall dimensions of several hundred meters.

Measuring the flux density of radon-222 at oil production facilities located in areas of perennial cryolithozone

DOI:
10.24887/0028-2448-2024-1-104-106

The perennial cryolithozone is unique and one of the most complex environmental conditions on the Earth. This phenomenon is of global importance for the study of natural processes, as well as for the development and application of technologies in various industries, including oil production. Permafrost conditions are of significant interest to the oil industry due to their potential impact on a variety of activities, including infrastructure development, resource exploration and environmental management. The oil production industry is actively developing in areas of perennial cryolithozone, since proven oil and gas reserves are located precisely in such regions. However, one of the important factors that must be taken into account is the release of radon-222 gas in these areas. One of the aspects that require special attention in the field of oil production in the permafrost zone is related to the measurement of radon-222 flux density. In permafrost areas, measuring radon-222 flux provides a valuable tool for assessing potential risks and mitigating their impacts. Long-term exposure to radon-222 can lead to an increased risk of developing cancer in oil industry workers, especially those who are closer to sources of radon radiation. Radon-222 is released from the ground and can penetrate buildings, potentially exposing employee to increased levels of radiation. The article discusses the results of determining the flux density of radon-222 in order to ensure safe working conditions and health protection for employees of NK Rosneft - NTC LLC.
