According to the analysis, that 67 % of studies are not data-supported, whereas 33 % are credible. Some study parameters were not employed due to the reasons described in the article. A scrutinized analysis of possible deviations in the results of the studies from the design concept for hydraulic fracturing is conducted. It is noted that fracture half-length and formation pressure determined by well testing differ from those determined by planning. Based on the results of the pressure draw-down curve, the author determines the dependence of the time required for the diagnosis of radial filtration mode on the range of reservoir permeability and the value of the half-length of a fracture. Based on the Nolte‒Smith plot, an approach to determining the nature of fracture development is proposed in order to obtain parameters sig-nificant for planning, control, and analysis of field development and geological and engineering activities and are used for detecting well deliverability and inflow area created due to hydraulic fracturing.","PeriodicalId":431138,"journal":{"name":"Proceedings in Cybernetics","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122107179","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}

Model parameters are identified using two alternative methods of regression analysis: mixed estimation and maximum consistency between the calculated and actual values of the output variable. The constructed versions of the model fully correspond to the content meaning of the independent variables included in their composition and have high accuracy.

Standard algorithms for tracking of maximum power point do not provide for a maximum global power of a solar power plant during real time mode due to low convergence. A model of aximizing the generated power of a reconfigurable solar power plant was developed as a modified fuzzy deep neural network based on the modified quantum-behaved particle swarm optimizer. This neural network consists of the following: convolutional units, recurrent neural networks, and fuzzy units. By processing the sensor signals and images of the solar array, the set modified fuzzy deep neural network generates a reference voltage and an electrical interconnection matrix of the parallel-serial solar array, maximizing its power under non-uniform insolation.

The decompo-sition of gas hydrate under this influence is faster at lower values of the reservoir’s initial hydrate saturation. The effects of 1 000 MHz and 2 450 MHz frequencies are much stronger than those of 400 MHz. The study shows that during heating times higher than 400 hours, 1 000 MHz frequency radiation electromagnetic heating is more efficient than that of 2 450 MHz frequency. Using the proposed mathematical model, it is possible to determine the optimal frequencies of the radiation source at a given time of heating the reservoir of a particular field. Moreover, the resulting calculation of energy efficiency (EROI ≥ 10) of this method for gas hydrate-extracted gas proves its competitiveness when compared to traditional methods of thermal impact on the reservoir.","PeriodicalId":431138,"journal":{"name":"Proceedings in Cybernetics","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122723415","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}
