Thermal Regime of Frozen Soils with Snow Covers at Combined Radiant and Convective Effects
Authors: Merzlikin V G , Zorich A O , Zagumennov F A 
Published: April 2020

Abstract
The paper examines the variability of the temperature profile (including the generation of its inversion by combined radiant and convective action) for the exposed snow cover, which determines the thermal regime of the underlying medium (dense firn or frozen soils and ground of low- and high-lands) in view of heating by a geothermal thermal influx. Experimental and theoretical researches allowed studying the effects daily radiating-conductive heating inside a snow layer (covered the underlying glaciological mediums) at conditions of the external impact by atmosphere convection (together with longwave thermoradiation) and solar shortwave penetrating thermoradiation. The possibility of the formation of heat conductive fluxes redirected to exposed superficial during subsurface radiant overheating - was shown theoretically in order to prevent thawing of the underlying media. For the first time inversion temperature profiles were registered inside snow thickness on the glacier surface near Elbrus at the height ∼ 4000 m. The authors interpreted this effect from the standpoint of scattering media optics. Snow cover was modeled as a semitransparent medium with volumetric albedo, scattering and absorption indices (coefficients), caused by the calculated parameter of internal radiant heat source function, corrected by the experimentally measured temperature profile of the investigated snow layer. It is shown that during the morning hours at intensive insolation and atmospheric negative temperatures, subsurface overheating inside the glacier is produced. This phenomena was observed experimentally on depth up to 5-40 sm using of thermodes of long measure probe. The obtained results are in the consent with theoretical estimations of authors and foreign researchers.
Experimental and Theoretical Study Focused on Transformation of the Processing Properties of Gold in the Operating Area of a Ball Tube Mill
Authors: Lebedev I F , Osipov D A , Gavriliev D M 
Published: April 2020

Abstract
The article is aimed at studying the process of free gold deformation extracted during grinding in various types of ball mills. Today, ball mills and similar machines are typically used for fine grinding of gold ores. Their working parts include armor plates of a shell, and balls used as grinding media loaded into the shell. Despite the fact that the ball mills dominate over the other fine grinding machines used to extract hard rock gold, they still have serious drawbacks. It is believed that only 2 to 20% of all consumed energy is spent directly on grinding, while the rest of it is used to overcome friction, heat formation, acoustic and mechanical vibrations, etc. In the meantime, mass deformation and degradation of free gold takes place in the mills. The particles degradation has a clearly adverse effect on their further benefication, and their shapes change to various extents as a result of deformation. If the deformation is aimed at forming an isometric shape of particles, their recoverability increases, while the reverse process decreases it.
Cadastral Challenges of Forest Resource Surveying in Belgorod Oblast
Authors: Kononova O Yu , Zatolokina N M 
Published: April 2020

Abstract
Private property as an institute first emerged in Russia in 1991. State Cadaster appeared as a result to keep land records. Russia’s policy today is to optimize the use and cost-effectiveness of natural resources. Cadaster is the main tool used to generate financial income. The more data is available in the Cadaster, the more profits can be made. The Russian Federation has the world’s largest forest resources. Forested lands account for 70% of Russian land; however, only 20% of the forests is recorded in the State Forest Register, while the rest is still not recorded in the Cadaster. Forest records are kept in the State Forest Register or in the State Cadaster; this duality entails greater costs for those who order and those who perform cadastral surveying. Since forest management does not use the coordinates used by the SFR, recording data on such forest plots is difficult. Forest surveying does not need to be approved by stakeholders, and neither do the boundaries defined by such surveying, as the boundary points are not landmarked.

Abstract
Enterprises of the oil and gas complex related to the budgetary-forming ones and they provide about 50% of the annual budget in our country. At the same time, these enterprises regarded as the most fire-hazard objects. Currently the problems of fire safety provision for the objects of the oil and gas complex are the most especially actual. The development of the enterprises accompanied by a complication of the technological processes and production as well. These processes invariably entail an increase of amount of combustible gases, combustible and volatile flammable liquids at these objects of oil and gas industry. As a result, it became possible the appearance and uncontrolled development of the fires which are capable to lead to the large-scale anthropogenic disasters B along with significant human, material and ecologic losses. Therefore, an estimation of the fire safety for the substances utilized at the objects of oil and gas complex proves to be a key element for the provision of the fire safety at the protected objects.

Authors: Yakimenko L , Ivanenko N 
Published: April 2020

Abstract
The article demonstrates high level of pollution in the waters and sediments of Ulysses Bay. The pollution can be traced through the sea life vital activity indicators. One of the causes of the negative effects on the bay ecosystem from human use is the lack of storm water treatment by shipyards which operate in the coastal zone and in the waters of Ulysses Bay in Vladivostok (Peter the Great Bay, the Sea of Japan). In this article it has been shown that the organoleptic and chemical indicators for the storm water discharged without treatment into the bay used for fishing activities do not comply to the requirements for storm water quality. The article suggests the design for the storm water treatment facility to be used at the shipyard which was used for the research. The use of the suggested facility – the combined facility for oil and sand interception – would ensure that the amount of pollutants discharged into Ulysses Bay are compliant to the maximum allowable concentration (MAC).
Modelling Atmospheric Properties in Industrial Geodetic Measurements
Authors: Mogilny S , Sholomitskii A 
Published: April 2020

Abstract
The article considers the questions of studying and modeling atmospheric properties in geodetic measurements on industrial objects near high-temperature aggregates. It is shown that atmospheric properties around such aggregates have significant differences, which influence geodetic measurements. The research was carried out on the basis of an industrial experiment on measuring atmospheric temperature field around a rotation kiln. The mathematical model of the air temperature field in the space around the kiln is divided into two zones: the first one – the space where the total station and sighting marks are positioned; the second one – the space from the shell surface to the distance ≤2.5m. The first zone temperature field is built on measurements made by inhausting thermocouple and interpolation between measurement points by Viner-Kolmogorov filter; the second zone field is built on measurements made on the shell surface by a pyrometer. The research showed that in the direction perpendicular to the aggregate axis the lines of equal temperatures are close to circles. The mathematical model of atmospheric temperatures allows to perform integration of differential equations of the sighting beam between any measurement points, to estimate the values of geodetic refraction, to choose more accurate measurement technology.
Solution of the Problem of Annular Space Gas Utilization in Wells Operated by Walking-Beam Pumping Unit
Authors: Gabdrkhmanova K F , Izmailova G R , Samigullina L Z 
Published: April 2020

Abstract
This article presents new approaches to solving one of the problems encountered in many oil fields - the disposal of gas accumulating in the annular space of production wells operated by walking-beam pumping units. This question is relevant because the accumulation of gas and the increase in its pressure affects the depression reduction and the fall of the dynamic level of the liquid, adversely affecting the downhole pumping equipment operation. Critical annular pressure is a value above 10 atm. Traditionally in order to bring the annular gas pressure in line with the linear, reverse wellhead valves installed in the wellhead fittings were used. The use of these valves reduces the annular gas pressure, but does not solve the problem of its subsequent disposal. The emphasis is on the technical and economic efficiency of the proposed associated gas utilization method.

Published: April 2020

Abstract
This article assesses the prospects for the use of geological and technical measures related to the creation of non-traditional methods. The essence of which is not only high manufacturability, but also energy saving with a significant expansion of geological criteria for their applicability. Hydraulic fracturing is widely used in wells operating an oil reservoir, which in most cases is proved theoretically and practically.
According to the results of geological field analysis, it was found that for the conditions of development of deposits of the Krasnoleninsky field, the introduction of hydraulic fracturing into wells is a tool, the reuse of which, regardless of the current water cut, will help to increase the productivity of production wells. A further increase in the efficiency of work is associated with their complex organization in a reasonable combination of well operating modes, hydraulic fracturing technologies, and optimization of the waterflooding system.

The Arctic regions include 13 regions of the Republic of Sakha (Yakutia), their territory occupies 52.56% of the entire territory of the republic. The delivery of fuel to the Arctic regions is fraught with large financial costs. They contain 155 sources of heat supply, out of 155 of which 83 work on solid and 72 on liquid fuel. The total fuel demand is estimated at 85.3 thousand tons of fuel equivalent. per year, of which a large proportion, 96%, falls on diesel fuel. To solve the problem of energy supply of the population in the arctic regions of yakutia the role of potential local sources of hydrocarbons is shown. Conducting prospecting and discovery of projected hydrocarbon deposits in the immediate vicinity of potential consumers will significantly optimize the fuel and energy balances of the Arctic and northern regions of the Republic of Sakha (Yakutia). The oil and gas prospectivity of the territory under consideration is shown

Authors: Glyaznetsova Yu S , Zueva I N , Chalaya O N 
Published: April 2020

Abstract
In the Arctic zone of Yakutia, geochemical studies have been carried out to study the state of the soil in one of the tank farms. The row of informative analytical indicators was used to characterize the composition of oil pollution and assess the features of its biodegradation processes in permafrost soils. The features of the chemical composition of oil pollution in soil samples with a long-term contamination are revealed and are taken into account at developing methods for cleaning soils from “old” oil pollution. An experiment on the biological treatment of soils with a biological product based on indigenous hydrocarbon-oxidizing microorganisms isolated from permofrost soils was conducted. The initial oil content was 34594 mg kg−1. After 3 months of incubation of a biological product, along with a decrease in the residual oil content, the composition of pollution changed in the direction of increasing the content of resin-asphaltene components and decreasing - hydrocarbons. The proportion of oxygen-containing groups and bonds has significantly increased in the chemical structure of alcohol-benzene resin. In the composition of alkane hydrocarbons, a redistribution is established both within the homologous series and between different rows of homologues. The degree of destruction of oil pollution reached 56.6%.

Published: April 2020

Abstract
The article discusses the use of ecologically and economically practical proved methods of neutralizing the soil ecosystems in Yakutia after emergency oil spills. Experimental studies have been made to develop a new biosorbent based on a natural sorbent. The natural zeolite Na and CA-differences from the Khonguruu deposit (The Republic of Sakha (Yakutia), Russia) is used as a base for obtaining the biosorbent. The necessary typification of zeolite deposits revealed at the stage of exploration, in order to determine the field of practical application of raw materials in the preparation of the field for industrial development. The types of raw materials according to the cationic composition difference are identified: clinoptilolite-heulandite and heulandite. A brief description of the material composition and averaged physico-chemical characteristics of various types of zeolite raw material is given. We present the results of the experimental application of hydrocarbon oxidizing microorganisms (HOM) immobilized on zeolite (clinoptilolite- heulandite series) from the Khonguruu deposit in oil-contaminated soils. It has been established that the obtained biomineral compositions provide a significant activation of petroleum hydrocarbons (HC) biodegradation in the soil. In general, the technology of using zeolite raw materials for cleaning up oil spills from different types of permafrost soils provides a significant ecological and economic effect, thus contributing to the reduction of the time for rehabilitation of disturbed lands and the improvement of the environment in the disturbed territory.

Research on Efficiency of Solvents of Paraffin Deposits
Authors: Ivanova I K , Semenov M E 
Published: April 2020

Abstract
Differential scanning calorimetry has been used to study the phase transition of commercial paraffins in asphaltene-resin-paraffin deposits (ARPD). Paraffin deposits have been collected from the surface of oil field equipment in the Irelyakhskoye oil and gas field (Sakha Republic (Yakutia). Gas condensate (GC) that is currently used in this field to remove deposits, as well as its mixture with cyclohexane and p-xylene, have been studied as ARPD solvents. The degree of crystallinity (DC) of paraffins has been identified to depend on the degree of aliphaticity of the mixed solvents used, with an increase in the degree of aliphaticity of the solvent, the DC of paraffins increases. Paraffins in the triple solvents are found to possess low DC and high melting points. The results of the research led to the conclusion that it is necessary to use GC with addition of aromatic concentrate to remove paraffin deposits in the oil field.
Method for Assessing the Environmental Impact on the Duration of the Safe Operation of Offshore Stationary Platforms (MSP) for the Extraction of Oil, Gas and Other Resources on the Shelf
Authors: Starokon I V 
Published: April 2020

Abstract
The article explores the problems of assessing environmental impacts on the duration of the operation of offshore oil and gas facilities. The methods used in the domestic and foreign regulatory frameworks to assess the duration of operation of offshore oil and gas facilities are analyzed. It is noted that the issues of the influence of loads causing alternating stress have been given significant attention, however, the issues of the “influence”, which also create various alternating stress, have not been sufficiently taken into account. Currently, with respect to offshore oil and gas facilities, there is no methodology that would make it possible to objectively describe both the nature of these impacts and provide numerical and analytical dependences of the impact of these effects on the duration of operation of offshore oil and gas facilities. The task is to systematize the effects that affect the duration of the operation of offshore oil and gas facilities, and to develop a mathematical apparatus that allows you to determine the specific numerical values of the variable stresses caused by these effects.
Frost Weathering as a Process of Degradation of Surface of Rocks under the Action of Internal Stresses
Authors: Popov V I 
Published: April 2020

AbstractThe article presents the results of studies of self-organization of ice inclusions in the surface layer of frozen moisture-bearing rocks. Frosty weathering of rocks is determined by the formation of inhomogeneous stresses in the surface layer. They are due to the random nature of the appearance of crystallization centers and further inhomogeneous growth of crystalline (ice) formations. They are narrow, rectangular inclusions of fixed sizes for which solutions of the theory of elasticity are known. An original model of heat and mass transfer in the surface layer of a moisture-containing rock under the influence of variable temperatures with a period of ∼ 12 hours is used. The correlated arrangement of crystalline formations is determined by the process of minimizing the total elastic energy of the ensemble of ice formations depending on the angle of their mutual orientation.
