The method consists in interaction of water with dissolved CO2 on the surface of iron-containing fillers. The process proceeds at temperatures starting from ambient conditions and does not require creation of high pressures or electric current in the system. The interaction is accompanied by intense evolution of gas phase with high content of hydrogen. Carbon is transformed into carbonates and small quantities of generated hydrocarbons. Influence of temperature and process parameters is studied for steel turnings used as a prototype of cheap fillers produced from metalworking wastes. The possibility to optimize the degree of CO2 utilization is shown by controlling the carbonized water saturation pressure. According to the results of considered and previous series of experiments, the achieved degree of CO2 utilization is up to 76-83%, with hydrogen content in the output gas of 63-82%.

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.

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.

The article investigates a method for improving the efficiency of the development system of a layered and heterogeneous productive formation of the «ryabchik» type by controlling the parameters of the well grid and well completion.

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.
