In the southern part of the Khoreyver depression, a structure of the first order, which is a fragment of the supra-order Pechora megasyneclise, ring and linearly elongated structures have been established - parts of the complex Assel-Sakmar reef system. In the Sandiveyskaya area, the reef formations of the Lower Permian are commercially oil and gas bearing. Several fields have been discovered here: Sandiveyskoye, Severo-Khayakhinskoye, Veyakshorskoye, Vostochno-Veyakskoye, Salyukinskoye and others, including those with high oil production rates. As a result of the analysis of 2D and 3D seismic data and a complex of drilling and well logging data, numerous reservoir zones with high porosity and permeability properties were identified and mapped in the upper parts of reef structures, which are highly promising objects for the search for oil and gas deposits in the Lyzayuskoye, South Sandivey and East Bagan areas. Keywords: reef systems; oil and gas reservoirs; filtration-capacitive 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». Keywords: hydraulic fracturing (fracking); frac design; mini-fracturing; fracture conductivity; proppant; modeling.

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.
