At present, for the purification of gases from sulfur compounds, amine solutions are mainly used, which become contaminated during operation, which entails a number of technological problems. We have chosen a list of key indicators characterizing the degree of contamination of solutions, which consists of the concentration of thermostable salts, the mass fraction of chlorine ions, the mass fraction of iron and nickel, and foaming solutions. The article presents a multiple description and essence of methods for determining the indicators of the degree of contamination of solutions. For testing, 10 regenerated MDEA and MEA solutions were selected. For each value obtained, the limit of the total error and the allowable interval of the value were calculated to determine the convergence and adequacy of the measurements. All values fall within the allowable interval, taking into account the characteristic error of MI, which indicates the reliability and expediency of using these methods. Keywords: methylethanolamine; methyldiethanolamine; thermostable salts; corrosion; electrical conductivity; foaming; cleaning; activated carbon; ion-exchange resin.

The study of breaks in sedimentation is of interest in various aspects. The role of biogenic and chemical sulfate reduction in the dissolution of carbonate rocks is emphasized. The formation of reservoirs of different genesis in sediments was established in the tested cases of erosive action. As a result of deep processing of deposits, identified denudations and the formation of a weathering crust, the conditions for the formation of large reservoirs of hydrocarbons in its thickness. The role of breaks in the change in the sedimentation regime in the marine on the continental part is considered; appearance of humic organic matter (OM) in sedimentary deposits of the Late Paleozoic. Representatives of representatives of humic OM in pre-salt deposits of the Caspian oil and gas province are given. In the Volga-Ural region, coal-bearing deposits of erosion-karst paleoincisions enhance the heterogeneity of Carboniferous deposits at catagenic depths. A feature of the relief of the erosion-sedimentary surface formed within the Astrakhan carbonate massif is noted. Fragments of alluvial fans preserved from erosion are fixed here. An analysis was made of the relationship between breaks in sedimentation and catagenetic unconformities. Keywords: Interruption; Carbonate deposits; Karst; Catagenesis; Collector; Oil and gas bearing; Reservoir.

Global climate change has a great impact on ecosystems. For this reason, there is a need for modern research on greenhouse gases and organic carbon. For the effective use of the findings, it is advisable to accumulate scientific results in a unified place, where there will be operational access and the ability to work with the data. The article discusses approaches to the formation of a regional information system (digital platform) on the example of the Republic of Bashkortostan – one of the regions where scientific research is carried out in 2022 at the sites of specially protected natural areas and areas of the Eurasian carbon polygon (experimental research sites). The platform is designed to work with decarbonization ecosystems based on one of the existing geoinformation systems with distributed access and display of information coming from measuring systems and stored in databases. Keywords: geographic information system (GIS); digital platform; greenhouse gases; decarbonization; ecosystems.

When implementing the SWAG technology, the degree of stability of the water-gas mixture plays a key role. A many factors of various nature is known to the suppression of the coalescence of gas bubbles is facilitated. This article presents the results of studies of the effect of surfactants of various compositions and concentrations on the operation of a multistage centrifugal pump when pumping water-gas mixtures. The foaming agent disolvan 4411 is determined to the degree of negative influence of free gas on the characteristics of the pump is significantly reduced. The reagent Neftenol VVD provides operating parameters very close to the characteristics of the pump when using disolvan 4411. The concentration of Neftenol VVD, recommended for addition to the water-gas mixture, has been determined. The expediency of choosing this surfactant is also due to the fact that the use of this reagent improves the injection capacity of wells. Keywords: multistage centrifugal pump; ejector; water-gas mixture; foaming surfactants.

In аrticle we analyze the drilling results based on three-dimensional geological and hydrodynamic models based on data from 115 wells in 28 different fields in the Volga-Ural and Timan-Pechora oil and gas provinces. The analysis of the results of production drilling of wells on the accepted geological and hydrodynamic models was carried out. The confirmation of the main elements of the geological three-dimensional model is considered. To differentiate the reasons for the deviation of the forecast flow rates associated with geological and hydrodynamic modeling, it is suggested to use the graph of comparison of the relative deviation of flow rates and the filtrationcapacitive properties predicted on the geological model. Efficiency and visibility of the separation of geological and technological reasons for the unconfirmed debits on the chart showed that, first of all, the factors related to reservoir development technologies and the forecast of the hydrodynamic model influence the flow rates. The study allows to choose effective measures to reduce the risk of failure to reach the planned production at oil fields, it is proposed to improve the methods of geological and hydrodynamic modeling in the direction of the development of the use of multivariate modeling technologies. Keywords: reservoir; predicted oil production; reservoir simulation modeling; porosity; permeability; reservoir properties.

The paper analyzes the features of the distribution of oil and water phases in the pore space of rocks with a mixed type of wettability. It is shown that when a two-phase fluid moves through an elementary micro-volume of a porous medium, the pore space of which is represented by both hydrophilic and hydrophobic channels, one of these adjacent channels can be saturated with only one of the phases in a mobile form. It is established that the change in the water saturation of the pore space over the area of productive formations during their flooding is the reason for the strong dependence of the residual oil saturation of the rock on the displacement pressure gradient. Hence, in particular, it follows that sealing drilling technologies used to increase oil recovery and increase the values of displacement pressure gradients in rocks with a mixed type of wettability will be more effective. Keywords: mixed type of wettability; flooding of productive formations; residual oil saturation.

Currently, various innovative technological approaches are used to develop deposits of hard-to-recover oil and gas reserves. To increase the efficiency of these activities, software products for the design of remedial operations can help. Hydraulic Fracturing Simulator (HFS) is an essential tool for developing hard-to-recover reserves and shale reservoirs. The hydraulic fracturing simulator makes the process of oil production in complex geological conditions safer and more efficient. There is a human factor in decision making in the endless iterative process at all stages of hydraulic fracturing application, which should be taken into account in software development. Foreign IT-solutions for modeling of geological and engineering operations (GEO) are considered to be the benchmark in the Russian market. However, there are promising domestic import-substituting developments, and one of such solutions is modeling software «Fractal», created in Ufa by «Tetaсom».
