The method allows to control the isolation process by regulating the gel-forming time by means of temperature and delivering the mixture to a given formation depth. To ensure mixing of the components of the composition in full and to prevent the formation of sediment, before injection, a solution of a gelling agent is added into the solution of the gel-forming initiator. It is possible to mix the components of the mixture directly in the wellbore by successively pumping solutions of the gel-forming initiator and the gelling agent. The results of oil sweeping experiments showed that the developed technology for isolating water inflow based on the use of a thermoactive gel-forming mixture significantly exceeds the known compositions in terms of technological efficiency. After applying the proposed technology, zones with increased oil saturation are involved in the development, there is also a decrease in the volume of produced water, and the profitability of production increases.

Based on analytical calculations by the method of J.E. Oddo and M.B. Thomson's analysis of the mixing processes used in the process of silencing waters on the compatibility and degree of salt deposition revealed that when mixing reservoir water and water of the silencing fluid under reservoir conditions at T = 30 °C and P = 7 MРa, the precipitation of non-organic salts of calcite CaCO3 with a sediment mass in the range of 0.39-0.77 g is predicted/l and CaSO4 anhydrite – 0.01-0.03 g/l.

For various types of reservoir, petrophysical dependences of permeability on porosity were built, which became the basis for the original permeability array of the model. The refined permeability array made it possible to significantly improve the history matching to the actual data after the first iteration. In this research, an array of Voronoi polygons was built, which allowed further targeted modification of petrotypes in the area of wells, taking into account the actual dynamics of well rates. Based on the results of calculations, by local modifications, the cumulative oil and liquid production were matched. Proposed approach of fissures distribution made it possible to reduce the degree of uncertainty of filtration parameters during history matching of the model to actual development data and increase the reliability of forecast calculations.

In this regard, the assessment of the climatic conditions is of particular relevance. This study presents the results of an analysis of climate change and digital mapping of soil temperature in the Yangan-Tau UNESCO Global Geopark (Russia). The steady increase in air temperature was revealed, which causes an increase in the sum of active temperatures and the duration of the warm period of the year. Annual total precipitation during 1966-2020 changed the sign of the trend: positive trend (increase in precipitation) in 1966-1990, while in 1991-2020 is negative. The hydrothermal indicators determined the increase in aridity during the warm period. Based on the analysis of changes in the climatic conditions of the geopark, a comparison was made of the temperature regimes of air and soil, and the relationship between these indicators in the snow-free period was revealed (R2 = 0.62). An approach is presented for digital mapping of the temperature regime of the surface layer of soils based on ground-based research data and the results of interpretation of the Landsat thermal bands. A significant relationship between soil temperature and Earth surface temperature for the snow-free period was revealed (R2 = 0.83). Based on the obtained regression model and Landsat 8-9 data for the snow-free period of 2013-2022 the map of the distribution of average temperatures of the surface layer of soil from May to October was produced, which clearly demonstrated the relationship between soil temperature and biomes.
