Abstract According to the US Energy Agency (EIA), Russia is the world leader in terms of the volume of technically recoverable "tight oil" resources (U.S. Department of Energy, 2013). To convert them into commercial production, it is necessary to create cost-effective development technologies. For this purpose, a strategy has been adopted, which is implemented at the state level and one of the key elements of which is the development of the high-tech service market. In 2017, the Minister of Energy of the Russian Federation, in accordance with a government executive order (Government Executive Order of the Russian Federation, 2014), awarded the Gazprom Neft project on the creation of a complex of domestic technologies and high-tech equipment for developing the Bazhenov formation with the national status. It is implemented in several directions and covers a wide range of technologies required for the horizontal wells drilling and stimulating flows from them using multi-stage hydraulic fracturing (MS HF) methods. Within the framework of the technological experiment implemented at the Palyanovskaya area at the Krasnoleninskoye field by the Industrial Integration Center "Gazpromneft - Technological Partnerships" (a subsidiary of Gazprom Neft), from 2015 to 2020, 29 high-tech wells with different lengths of horizontal wellbore were constructed, and multistage hydraulic fracturing operations were performed with various designs. Upon results of 2020, it became possible to increase annual oil production from the Bazhenov formation by 78 % in comparison with up to 100,000 tons in 2019. The advancing of development technologies allowed the enterprise to decrease for more than twice the cost of the Bazhenov oil production from 30 thousand rubles per ton (69$/bbl) at the start of the project in 2015 to 13 thousand rubles (24$/bbl) in 2020. A significant contribution to the increase in production in 2020 was made by horizontal wells, where MS HF operations were carried out using an experimental process fluid, which is based on the modified Si Bioxan biopolymer. This article is devoted to the background of this experiment and the analysis of its results.

Abstract Wells with extended horizontal wellbore (HW) drilling with multistage hydraulic fracturing (MHF) is necessary for commercial oil production from Bazhenov formation (Vashkevich et al., 2015; Strizhnev, 2019). Today the maximum HW length for Bazhenov formation wells is 1500 m (Strizhnev, 2019, Korobitsyn et al., 2020). In international practice the maximum HW length for shale oil production is around 3000-400 m (Rodionova et al., 2019). Pump Down Perforator (PDP) technology is used for MHF: a liner is run in hole and cemented, then perforation and hydraulic fracturing (HF) are successively performed by stages at equal distances from the end to the beginning of HW to create a branched system of fractures in Bazhenov formation. Performed HF stages are isolated with special packer plugs (insoluble blind, dissolvable blind, insoluble with seat for dissolvable ball or dissolvable with seat for dissolvable ball)) (Mingazov et al., 2020). Consequently, the fluid inflow into the well is occurred along whole HW and the flow rate increases from monotonically from the end to the beginning of HW and has maximum value at last HF stage. The numbers of HF stages are about 24-30 (number of perforating clusters - 100) at one well in Russia and 50 in the world (Alzahabi et al., 2019). One of important parameter during HF is the speed of HF fluid injection into the formation. Tubing outer diameters 114-140 mm. are used in HW to increase the injection rate and reduce friction losses in the well. The flow rate of HF fluid in this case reach to 14-16 m3/min (Ogneva et al., 2020; Astafiev et al., 2015). Monobore wells construction is planned to use with outer diameter 140 mm. A stinger is used as sealing element between tubing and liner to minimizing risk of HF liquids leaks into the annulus (Astafiev et al., 2015). As a result, the inner well diameter from wellhead to bottomhole is around constant in the process of MHF. The pressure in the hydraulic fractures and the collector near fractures after MHF is highly exceeded the initial reservoir pressure. Hence wellhead pressure after MHF in water filled well is about 100-150 bar (Jing Wang et al., 2021). This fact significantly limits downhole well operations because of requires killing (tubing change, let down ESP, etc.). These works are required heavy well killing fluid because of high overpressure. It is undesirable because of it can reduce the fracture conductivity, worse well bottom zone properties and reduce well productivity. Therefore, the well is working at flowing mode in initial period usually until the reservoir pressure in the drainage area is decreased at the hydrostatic level or below (Jing Wang et al., 2021). After that the well can be killing using technical water with a density of 1.01 – 1.07 g/sm3 (the use of well-killing fluid with a density higher than 1.1 g/sm3 is undesirable). The possibility of well flowing working depends on properties of collector and reservoir fluid: High gas-oil ratio (GOR) and reservoir conductivity help well flowing until reservoir pressure drop off hydrostatic pressure.

The article is meant to analyze current problems and prospects for the development of effective tax policy as part of digital transformation of Russian economy. Introduction of a digital tax and the consequences of the digital tax reforms in the EU, the USA and OECD countries are highlighted. The necessity of qualitative transformation of the tax system of the Russian Federation in response to modern challenges is substantiated, taking into account the changes of the Tax Code of the Russian Federation adopted at the end of July 2020. The authors suggested their own concept of a digital tax and the prospects for its adoption in Russia, and consider it inappropriate to impose taxes on Internet users who do not use the Internet for business. Today, the main focus should be made on creating and testing effective technologies that allow on-line monitoring the tax basis of digital economy entities, taking into account the cross-border movement or use of digital products (goods and services). In addition, it would be extremely important to provide for a potential tax exemption for part of the profits of international ICT companies that are received on the territory of the Russian Federation and reinvested in joint with Russian companies projects in the high-tech for civil purposes area.

Степень технологической и технической зависимости отечественных производителей овощных культур от зарубежных производителей с.-х. техники, а также их техническая оснащенность специализированными машинами объясняется высокими затратами на производство овощей, особенно на уборку, что при общем дефиците ручного труда приводит к сокращению площадей, нарушению технологии выращивания и соответственно снижению урожайности. Цель исследований – определить современное состояние технологического и технического обеспечения производства овощных культур в Российской Федерации. Для достижения поставленной цели использовали методологию системного анализа и синтеза, математической статистики, численные методы решения аналитических зависимостей. Статистические исследования современного состояния технического обеспечения производства овощей в России могут служить основой для построения модели и разработки концептуальных принципов модернизации технологического и технического обеспечения работ в овощеводстве. Определена потребность товаропроизводителей в современных высокотехнологичных комплексах машин для производства овощных культур. Проведенные статистические исследования позволили оценить современное состояние с.-х. машиностроения по выпуску необходимого для товаропроизводителей количества машин. Повышение объемов производства овощной продукции неразрывно коррелирует с уровнем технического обеспечения отрасли овощеводства в целом, что подтверждает уровень локализации с.-х. машиностроения РФ, а также Беларуси и Казахстана, где с.-х. машиностроение представлено широкой номенклатурой предприятий, выпускающих комплексы машин от предпосадочной обработки почвы до послеуборочной обработки товарной продукции. Для возрождения с.-х. машиностроения и развития рынка средств механизации аграрного производства определены основные механизмы обновления парка сельхозтехники – преимущественно привлечением кредитных ресурсов коммерческих банков и лизинговых компаний. Кроме того, интенсивность ведения сельского хозяйства в современных условиях производства невозможна без высокого уровня насыщения машинно-технологических комплексов средствами интеллектуализации. Получать качественную конкурентоспособную продукцию можно только при использовании современных высокопроизводительных машин, обеспечивающих совмещение технологических операций, в конструкциях которых заложены системы автоматизированного управления технологическими процессами, учета почвенного плодородия, обеспечения экологической чистоты агроландшафтов. The degree of technological and technical dependence of domestic producers of vegetable crops on foreign producers of agricultural machinery, as well as their technical equipment with specialized machines, is explained by the high costs of vegetable production, especially for harvesting, which, with a general shortage of manual labor, leads to a reduction in area, disruption of cultivation technology and, accordingly, a decrease in yield. The purpose of the research is to determine the current state of technological and technical support for the production of vegetable crops in the Russian Federation. To achieve this purpose, we used the methodology of system analysis and synthesis, mathematical statistics, numerical methods for solving analytical dependencies. Statistical studies of the current state of technical support for vegetable production in Russia can serve as a basis for building a model and developing conceptual principles for modernizing technological and technical support for work in vegetable growing. The need of commodity producers for modern high-tech complexes of machines for the production of vegetable crops is determined. The conducted statistical studies made it possible to assess the current state of agricultural engineering for the production of the number of machines necessary for commodity producers. The increase in the production of vegetable products is inextricably correlated with the level of technical support for the vegetable growing industry as a whole, which confirms the level of localization of agricultural machinery in the Russian Federation, as well as in Belarus and Kazakhstan, where agricultural machinery is represented by a wide range of enterprises that produce complexes of machines from pre-planting tillage to post-harvest processing of commercial products. For the revival of agricultural machinery and the development of the market of agricultural production mechanization tools, the main mechanisms for updating the agricultural machinery fleet are determined-mainly by attracting credit resources from commercial banks and leasing companies. In addition, the intensity of agriculture in modern production conditions is impossible without a high level of saturation of machine-technological complexes with means of intellectualization. It is possible to obtain high-quality competitive products only with the use of modern high-performance machines that ensure the combination of technological operations, in the designs of which there are systems for automated control of technological processes, accounting for soil fertility, ensuring environmental cleanliness of agricultural landscapes. Key words: vegetable growing, vegetable seeders, transplanters, vegetable harvesting equipment.

The relevance of the publication topic is argued by the need for an in-depth study of the globalization process, which is global financial, political and cultural integration, unification, the global division of labour, the planetary migration of capital, human and productive resources, standardization of legislation, and interference of cultures of the world community. The theoretical and practical goals of the publication are to study causal algorithms for the formation of a negative scientific and production balance of the Russian Federation and an increase in disproportions between the import and export of high-tech products, as well as a comparative description of global development as a symbiosis of contradictory trends in the subordination of the world economy to the interests of transnational capital. The theoretical and methodological basis of the publication was the scientific works of domestic and foreign scientists studying the globalization of the industrial economy due to the intensification of international scientific and technological competition and the expansion of the innovation market, deepening of specialization and division of labour, and the increase in the risks of producing high-tech products at the national and world levels. Scientific novelty lies in the authors’ interpretation of such socio-economic advantages of globalization as economies of scale, stimulation of labour productivity, rationalization of production at the interstate level and the spread of innovative technologies, cost reduction, price regression, achieving sustainable growth in the well-being of society, on the basis of which the development is confirmed global industrial economy on a research basis characterized by such attributes interdependence, asymmetry, regionalization and diversification, regression efficiency, inclusiveness, resource and raw material demarcation, a high degree of uncertainty and of the economic risk. The practical significance of the results obtained is determined by an in-depth analysis of the American (based on differentiation of labor and specialization of personnel, demarcation of labor duties, concentration of scientific and production efforts on a purely economic result) and Eurasian (characterized by mobility and compactness of production processes, saving transaction costs, adaptability to market conditions and availability of labour-tolerant staff) strategies for innovative development of industrial economics. Based on a critical rethinking of the American and Eurasian strategies, proposals and recommendations are formulated on the formation of the scientific and technical policy of the Russian Federation

Abstract Profitable development of hard-to-recover reserves often involves drilling of horizontal wells with multistage hydraulic fracturing to increase the oil recovery factor. Usually to monitor the fracture sweep efficiency, pressure transient analysis is used. However, in case of several fractures this method delivers only average hydrodynamic parameters of the well-fracture system. This paper illustrates the value of temperature logging data and demonstrates possibilities of the 3-D thermo-mechanical modelling in evaluating the differential efficiency of multi-stage hydraulic fracturing.
