Innovative Industrial Clusters in the Context of Digitalization and Sustainable Competitiveness

To ensure Russia's sustainable competitiveness, it is necessary to create an infrastructure that allows creating globally competitive technologies and products. The authors suggest that industrial clusters can drive the country’s sustainable economic and innovative development. The research methodology is based on the content of the concept of sustainable competitiveness and cluster theory. The study was carried out using the methods of regression analysis. The systematization of foreign and Russian researchers’ ideas contribute to the conclusion that the cluster approach for ensuring sustainable development and competitiveness in the digital era is regarded as absolutely reasonable. In order to test the hypothesis of the study using regression analysis, a model has been built to assess the dependence and influence of the number of clusters in Russia Federal Districts on the main indicators of economic innovative development of these territories. The regression models constructed by the authors demonstrate a clear dependence of region economic and innovative development indicators on the clustering level. The authors of the present research recognize that clustering should be considered one of the basic elements in the system of national and regional sustainable competitiveness

Optical and chromatographic methods for efficiency analysis of non-stationary production

The problem of cost-effective oil production from carbonate reservoirs becomes more and more important every year due to a decrease in oil reserves in terrigenous reservoirs. Oil extraction from carbonate reservoirs is always associated with the low filtration properties of the rock matrix and the dense fracture network presence. One of the most effective methods at this development stage for carbonate reservoirs is the non-stationary drainage technology. The development of non-stationary deposit drainage technology by determining the effective action time with different work periods and well accumulation, due to deformations in the fracture system, will allow reducing wells watering percentage. As a result of fluid flows redistribution in the formation, unprocessed areas are attracted by capillary impregnation. An important stage in the application of non-stationary action is the study of oil optical properties. To assess the quality of the reserves involved in the development, laboratory studies of the deposit non-stationary production efficiency of the Romashkinskoye oil field were carried out. The investigations were carried out using a spectrophotometer and a chromatograph. The influence of non-stationary selection on the wells operation dynamics and on the final ORC was determined
