    A mathematical model, numerical algorithm and program code for simulation and long-term forecasting of changes in permafrost as a result of operation of a multiple well pad of northern oil and gas field are presented. In the model the most significant climatic and physical factors are taken into account such as solar radiation, determined by specific geographical location, heterogeneous structure of frozen soil, thermal stabilization of soil, possible insulation of the objects, seasonal fluctuations in air temperature, and freezing and thawing of the upper soil layer. A parallel algorithm of decomposition with splitting by spatial variables is presented

    Simulation of long-term influence from technical systems on permafrost with various short-scale and hourly operation modes in Arctic region

    Full text link
    Technogenic and climatic influences have a significant impact on the degradation of permafrost. Long-term forecasts of such changes during long-time periods have to be taken into account in the oil and gas and construction industries in view to development the Arctic and Subarctic regions. There are considered constantly operating technical systems (for example, oil and gas wells) that affect changes in permafrost, as well as the technical systems that have a short-term impact on permafrost (for example, flare systems for emergency flaring of associated gas). The second type of technical systems is rather complex for simulation, since it is required to reserve both short and long-scales in computations with variable time steps describing the complex technological processes. The main attention is paid to the simulation of long-term influence on the permafrost from the second type of the technical systems. © 2017 Author(s).The work was supported by Russian Foundation for Basic Research 16–01–00401 and program of scientific research UrB RAS 15–16–1–10

    The diffculties related to open loop geothermal systems using includes, in particular, the fact that there is a reverse injection of the cold water through an injection well into an underground aquifer from which hot water is extracted. This necessity for an injection well presence is caused the thermal water from an underground reservoir possible to be high mineralize and to contain toxic compounds and metals, and in most cases one have to avoid to discharge these waters into ground surface natural water systems. An open loop geothermal system of three wells is considered, which can be both productive and injection wells. The developed algorithms and programs allow to select an optimal system configuration of three wells for a specific geothermal deposit. The results of numerical calculations for various variants of the geothermal system are presented. © 2018 Author(s).The work was supported by Russian Foundation for Basic Research 16–01–00401 and program of scientific research UrB RAS 18–1–1–8

    Simulation of thermal stabilization of bases under engineering structures in permafrost zone

    Constructions on permafrost have to be ensured with reliability of the foundation, which, under the influence of various heat fluxes and annual freezing (thawing) of the soil, may get stressed, that leads to destruction of the foundation and the engineering structure itself. To assess the thermal impact of engineering structures on the ground, a computer simulation of the construction pads is used. Thermal stabilization of the soil is considered to be carried out due to freezing with the help of seasonally operating cooling devices for some time prior to the beginning of construction, or placing on site various technical systems that are sources of heat. The results of numerical calculations illustrating the effectiveness of preliminary thermal stabilization of the soil under the base of the engineering structure are presented. © 2018 Author(s).The work was supported by Russian Foundation for Basic Research 16–01–00401 and program of scientific research UrB RAS 18–1–1–8

    Проведено аналіз сучасного стану та тенденцій розвитку підприємств машинобудування України. Зроблено висновок про необхідність моніторингу дослідження машинобудівної галузі й визначення основних перешкод у процесі розвитку. Аналіз умов господарювання показує, що резерви підвищення ефективності вітчизняного машинобудування на основі використання екстенсивних чинників зростання вичерпані. Життєво необхідна переорієнтація вітчизняної промисловості на інтенсивний шлях розвитку, який передбачає необхідність вирішення комплексу взаємопов'язаних і взаємообумовлених накопичених проблем у законодавчій, нормативно-правовій, фінансово-економічній, освітній, кадровій та інших сферах.Machine-building enterprises in the different areas are considered to be the "base" of the national economy, their success determines the effective functioning of its systems and related sectors. The analysis of the current state of machine-building industry and industry in general, provides a background to state that despite some positive trends in recent years the problems in this field has not been overcome yet. The absence of deliberate government strategy of development has meant that having found themselves in a situation of self-financing and in the absence of practical experience in the market, most of the machine-building enterprises has been forced to exist in survival conditions. The lose of market position, the collapse and bankruptcy of many enterprises, the outflow of qualified personnel, critical moral and physical aging processes and technology has been resulted. Because most of the m achine-building enterprises of Ukraine still have the structure of production and use of technology which has been introduced in Soviet times and are designed to work in a planned economy. In addition, depreciation of assets in financial balance of enterprises, which has been occurred in turn determines their low credit and investment attractiveness. All these factors foresee that the reserves of national machinery improvement on the basis of extensive growth factors have been exhausted. The reorientation of domestic industry in an intensive way of development, which requires the solution of complex interrelated and mutually accumulated problems in the legislative, legal, financial, economic, educational, personnel and other areas is vital. Time factor is very important taking into consideration the fact that developed countries re-eguipment their industries every 7-10 years

    Optimization of location of injection wells in an open geothermal system

    Full text link
    A geothermal open loop system consisting of one production well and several injection wells is considered. The production well serves to raise hot water from a geothermal underground reservoir, which can be used for building heating or for other purposes. As a result, the water is cooled and then pumped through injection wells back into the geothermal reservoir. The cooled water begins to be filtered in the reservoir in the direction of the production well. A mathematical model describing the distribution of a cold water front in such a system is presented. A software package has been developed that makes it possible to evaluate the efficiency of the location of injection wells in a geothermal reservoir in order to increase the operating time of such a system, since the operation of the geothermal system life is over as soon as the cold water front reaches the production well. © 2019 Author(s).Russian Foundation for Basic Research, RFBR: 19–07–00435The work was supported by Russian Foundation for Basic Research 19–07–00435
