Purpose. Research and substantiating the expediency of cement mix formulations of grout slurries with different Defecate additive content and their effective use when cementing the reservoirs prone to absorption of the cement slurry, as well as to prevent behind-the-casing flows and for cementing operations in the zone of abnormal pressures (hydraulic seam fracturing). Methods. Analytical and experimental studies of the physical-chemical grout slurry properties are used: determining the influence of the Defecate additive content on the cement mixture technological properties; study of a change in the grout slurry rheological characteristics at various temperature conditions; testing the formulation of grout slurry with different rates of strength development; substantiating the economic efficiency of using the grout mixtures with the Defecate additive. Findings. It has been revealed that the cement mixture fluidity increases by 10-20% with the addition of a Defecate in the proportion of 5-20%. With a further increase in the Defecate content, the stone strength deteriorates, and with a decrease, the grout slurry concentration increases. It has been found that when Defecate is added to the cement mixture in a proportion of 20%, the pumpability of the cement slurry doubles, that is, from 1.5 to 3 hours. The economic efficiency has been proved of using these mixtures during insulating activities in the well No. 122 of the Kulychykhynske NHKR (oil and gas condensate field). The improved formulations of grout slurry with the addition of a Defecate are recommended to be used during repair-insulation works for delimitation of producing reservoirs prone to absorption, behind-the-casing flows and hydraulic fracturing. Originality.New dependences have been determined of the technological and rheological characteristics of grout slurries on the content of the Defecate additive, which makes it possible to set its optimal proportion. Practical implications. The use of grout mixture based on the Defecate will expand the raw material base for obtaining lightweight grout slurries. The properties of such a solution make it possible to use a grout mixture for cementing wells in the zone of abnormal pressures, while reducing the costs for the process of reservoir delimitation.

The aim of this study is to determine the need for cluster formations; to identify the influence factors on the creation of a cluster of thermal power companies in Poltava region. The method of evaluating the efficiency of formation of this cluster has been developed. The methodological framework of this research is general scientific dialectical method of cognition, in which the research object is studied as a dynamic system in the process of its development. The formation of the main directions of thermal power company development was carried out on the basis of dialectical, historical and systematic methods. In the process of studying and generalization of scientific and practical development methods of comparison, analysis and synthesis, induction and deduction were applied. Also the study is based on regulatory and economic instruments, economical studies and studies of scientific research institutions. As a result of the study the main participants of the cluster formation were identified. So it may be comprised of the members of the cluster, generating thermal energy, the thermal energy consumers and the region where the cluster of thermal power companies will be formed. According to the participants of cluster associations the factors of influence on economic and social effect from implementation of the cluster thermal power companies in the Poltava region were formed. We determined that to reduce the rate for thermal energy it is necessary to conduct a number of activities. The application of the proposed measures will significantly reduce the services cost of thermal power companies. The cost of thermal energy and the distribution among the participants of cluster associations were calculated on the example of Poltava region utility production enterprise of heat economy "Poltavateploenergo". The participants are heat producers, transport companies, distribution and heat supply companies, repair work companies, construction work enterprises. It is established that the overall effect of cluster members has both quantitative and qualitative nature. The impact on consumers is qualitative. It is based on the fact that the tariff for consumers remained unchanged in the medium term (five years). The essence of economic effect is in the quality and timeliness of services thermal management. The overall effect of its work influences all members. It occurs when there is the formation and implementation of cluster thermal power companies. But in addition to the advantages of cluster associations its major problems were presented in the work. Among them there are the following problems: the lack of informativeness of executive authorities and business representatives in the application of the cluster approach; the lack of public policy to ensure the systematic approach and organization of interaction between different levels of executive authorities in the implementation of cluster projects; lack of institutional and financial support to cluster initiatives; lack of trained personnel in the organizational aspects o...

Annotation. Introduction. The implementation of measures to reform the economy as a whole, agrarian reform and, in particular, land relations in agriculture, was one of the factors influencing the change in the structure of the resident population in terms of economic activity and changes in the agricultural labor market. Analysis of the distribution of the population of Ukraine by economic activity indicates a decrease by almost one third of the number of the economically active population in 2019 compared to 2000. There is also a trend towards a decrease in the number of those employed in economic activity. Purpose. The aim of the article is exploration of employment indicators (formal and informal) and unemployment of the rural population in Ukraine and identification of the main trends. Results. It has been established that the employed rural population is less educated and, accordingly, they perform mostly unattractive types of work that do not require high qualifications. It was revealed that workers in rural settlements have fewer job opportunities at their place of residence. In villages, the number of people who are employers is almost half. The biggest problem in rural areas is self-employment or predominantly employment in private households. A sharp increase in the share of unemployed youth who cannot find a job after graduating from educational institutions has been established. The situation with regard to youth employment in the villages of Ukraine is especially difficult. It turned out that 2/3 of workers in rural areas are employed in the informal sector. Moreover, two urban residents of this sector prefer hired labor, in agriculture, on the contrary, self-employed make up 74.0%, that is, they work in a peasant farm for agricultural products. In half of the cases, informal employment is carried out in agriculture. Conclusions. The unemployed urban dweller is more educated and therefore has more advantages over the rural dweller in terms of employment. Unemployed people in cities have more opportunities to choose a job, therefore they are more active when they leave their jobs of their own accord and depend on the seasonality of their work. For 1990-2019 the average number of full-time agricultural enterprises decreased 12.2 times due to the liquidation of agricultural enterprises. One of the reasons was the denationalization and privatization of enterprises in Ukraine, especially in rural areas, which were not supplemented by effective mechanisms for the employment of people, including by promoting the development of entrepreneurial activity. Keywords: labor market, employment, informal employment, unemployment, economically inactive population.
