The task of synthesizing a universal apparatus that would cope with all the difficulties is extremely difficult. For an optimal solution to the problems facing this area, it is necessary to use multi-agent complexes of robotic systems. As a result of the analysis of the available devices, their functions, the tasks they perform, as well as highlighting the patterns of their use, we have proposed two typical scenarios for the use of a multi-agent complex. The existing backlog of NPP PT Okeanos JSC, as well as many years of experience in the development and operation of marine robotic systems allow developers to be confident that with the proper level of support from potential customers, the application concepts described by the authors are feasible in practical realities, and not only on paper and the results of theoretical calculations.","PeriodicalId":383927,"journal":{"name":"Engineering and Mining Geophysics 2021","volume":"308 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-04-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114524852","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 proposed approaches are optimized directly for solving “multisource” problems for further application in data processing systems. For constructing finite element approximation, we use optimized non-conforming hexahedral meshes allowing to drastically reduce the number of degrees of freedom while keeping the required solution accuracy. In addition, to provide calculations with a large number of positions of the transmitter-receiver set, the space-time grouping of subtasks corresponding to different positions of the airborne system and parallelization were used. We present a comparison of the developed computational schemes that perform calculations both directly in the time domain and in the frequency domain, as well as a comparison with the results of other authors. It is shown that the solutions obtained using different approaches are in good agreement with each other. The computational costs required for calculating the electromagnetic field taking into account the IP effects in a complex 3-D medium with topography are about 10 s per position. This will make it possible to use this approach in the future in systems for processing airborne data.","PeriodicalId":383927,"journal":{"name":"Engineering and Mining Geophysics 2021","volume":"64 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-04-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123470406","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 main object of study is the largest tar sand deposit - Alberta (western province of Canada).There are some problems with the production of such oil: 1) Reservoir heterogeneity associated with interlayers of clays and shales. This is a significant obstacle to vertical vapor migration; 2) watercut zones. Based on this, the following tasks arise before the electrotomography: 1) Select tar sand layers and estimate their thickness; 2) Select the conductive horizons (clay, shale, water) that may be present in the oil-bearing strata. The assessment of the capabilities of electrotomography was carried out using simulation with subsequent inversion. Models were created to match the geological structure of the region (Alberta, Canada). Comparing the results of solving the inverse problem (inversion) with the starting model gives this estimate. In the process of modeling, a pole-dipole + dipole-dipole electrotomography unit was used.","PeriodicalId":383927,"journal":{"name":"Engineering and Mining Geophysics 2021","volume":"149 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-04-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121395569","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}
