On the basis of economic and mathematical modeling of geological and economic characteristics of shale formations, from which successful shale gas mining is currently being carried out in the world, correlation-regressive dependencies have been established. They allow to carry out a predicted estimation of the gas content, the initial rate of gas extraction wells, the marginal cost limit, at which a break-even production of natural gas from shale formations is possible. Using these dependencies, an analysis of the resource potential of slate formations has been carried out and it has been established that in the Eastern region stratigraphic complexes with promising shale formations are included: Devonian deposits - Upper Devonian (Famensian tier); coal deposits - Lower Carboniferous Complex (Tourney, Viseu, Serpukhov Tiers); middle-complex complex (Bashkir and Moscow tiers); Carboniferous complex (Kasimovsky and Gzhel tiers). Yevgenivsko-Druzhelyubivsk, Mirgorod-Livensk, Borkivsk-Velikzagorivsk and Zachipelsk-Livensk areas are the most investments-attractive in the prospects for shale gas extraction in the Eastern region. In the Western region, prospective stratigraphic complexes include deposits of the Cambrian, Silurian and Oligocene-Miocene age. The most investment attractive for shale gas extraction in the Western region is Davydivsky, Rava-Russkaya, East-Lishinskaya and Oleska districts. In the Southern region, perspective shale gas extraction is the deposits of the Middle Jurassic, the upper part of the Visean tier and the lower part of the Serpukhov tier of the carbon fiber of the Pre-Dobrug Trough. The results obtained can serve as a basis for investors to select priority objects for the development of natural gas resources from shale formations in Ukraine.","PeriodicalId":59694,"journal":{"name":"石油与天然气化工","volume":"83 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90986671","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The conditions for the development of organic agricultural production are given, namely: the presence of large areas of environmentally friendly agricultural land; high fertility of soils; favorable climatic conditions; low level of use of mineral fertilizers, plant protection products; presence of potential consumers market; Export attractiveness of organic products for EU countries; provision of the agrarian sector of the economy by labor resources. \u0000The efficiency of production of organic agro production, which is determined by internal (organizational, techno-technological, economic, marketing) and external (economic, institutional, legal, natural-ecological, social) factors, is investigated. \u0000The reasons that hinder the efficiency of production of organic products in Ukraine, which can be attributed to: imperfect institutional support and lack of state financial support; Innovative passivity of most manufacturers and management structures; lack of awareness of producers regarding the specifics of organic production and the public regarding the benefits of organic products; the predominance of exports of organic raw materials; processing, production, wholesale and retail trade in organic products of consumption are still underdeveloped; deficit of grain and other agricultural crops of organic origin; insufficient number of cattle as the main producer of organic fertilizers; high cost of borrowed funds; high ethnogeny load on the area of ​​Central and Eastern Ukraine. \u0000The evolution of the organic agricultural market will lead to the development of the relevant infrastructure. Agriculture of Ukraine has all the conditions for the development of organic agricultural production, since the soil-climatic allow to significantly expand the volume of organic farming. Co-operation of the organic agricultural sector in Ukraine is presented in the form of dairy cooperatives, which are intended for the sale of milk at more attractive prices. The cooperative movement makes it possible to combine efforts to create real competition for powerful agrarian enterprises and, at the same time, to promote the spread of organic agricultural production.","PeriodicalId":59694,"journal":{"name":"石油与天然气化工","volume":"36 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-05-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77784670","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Project management, like change management, is a well-developed field of management theory. Project management implies the application of certain approaches, the most common are functional and process approaches. The purpose of the article is to consider the application of project management in the context of interaction with functional and process approaches. Critical analysis of scientific views on functional and process management is carried out. It is proved that, in spite of all the advantages of the process approach, it is the functional specialization that provides the least costly execution of individual operations within the business process of the project. The result of both functional and process approaches is the simultaneous design of the organizational structure (functional areas) and the order of interaction within this structure (processes). The interaction and combination of functional and process approaches from the point of view of project management are highlighted. Due to this, a comparative analysis has been made on the criteria: orientation approaches, the interaction of structural units, the principle of constructing the organizational structure, the object of management, the concentration of management, the efficiency of the units, the information exchange, the speed of the adoption of managerial decisions. It is emphasized that in project management considerable attention is paid to effective coordination of work of separate units and strengthening of constructive interaction between functional units involved in the project. Thus, it has been proved that the synergy between functional, process and project approaches ensure manageability, efficiency in decision-making and increasing the efficiency of business processes.","PeriodicalId":59694,"journal":{"name":"石油与天然气化工","volume":"36 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-05-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88678392","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
