It has been shown that the reservoir properties of the rocks are quite low, while most of the voids are filled with highly viscous hydrocarbons. Siliceous-carbonate and carbonaceous-siliceous highcarbonaceous rocks have the best reservoir properties. The void space in the core samples is mainly of the porous-fractured type, the cavernporous-fractured type is locally noted. The formation of voids is due to both sedimentation and post-sedimentation factors and is associated with the processes of recrystallization, dolomitization, leaching and cracking. Microtomographic studies of high-angle-related rocks made it possible to study local zones and obtain data on the microstructure and capacitive characteristics of the void space in areas not accessible for decoding by other methods. It has been shown that a significant part of the voids in high-carbon rocks is confined to the shells of tentaculites and there is an increase in porosity in these areas.","PeriodicalId":9748,"journal":{"name":"Chemical and Petroleum Engineering","volume":"69 1","pages":""},"PeriodicalIF":0.3,"publicationDate":"2023-08-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86093127","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The uniqueness of this modeling approach is associated with the prompt acquisition of mechanical properties along the well paths of the field, which is especially important in conditions of insufficient geomechanics data. \u0000Traditional three-dimensional geomechanical modeling is a time-consuming and resource-intensive process. The data often describe the mechanical properties and stress-strain state of the rocks within the current drilling or development sector of the field and do not take into account the interwell space, especially in poorly drilled areas of the field. The method of real-time 3D geomechanical modeling makes it possible to quantify values of minimum horizontal stress used in hydraulic fracturing simulators, as well as static and dynamic Young's modulus and Poisson's ratio over the entire field area using the optimal amount of resources and in a shorter time. \u0000Based on the built three-dimensional cubes of elastic properties and stresses, correct data were obtained in the inter-well space, their vertical and lateral changes were analyzed, and frac design data were obtained at any well drilled through the simulated targets of the field. \u0000This paper covers the Arlanskoye, Znamenskoye and Yugomashevskoye fields (Bashneft PJSC). The target targets are carbonate deposits: Kashira and Podolsk strata of the Arlanskoye field, Tournaisian strata of the Znamensky field and Bashkir-Vereisky strata of the Yugomashevsky field. \u0000For the carbonate rocks of the target targets, laboratory core studies were carried out to determine elastic properties, and stable regional core-core relationships were obtained in the intervals of lower and middle Carboniferous carbonate deposits. \u00001D geomechanical models were built in RN-SIGMA software 84 wells at the intervals of the study targets.

For the first time, the method of small-angle X-ray scattering (SAXS) has demonstrated the possibility of analyzing not only secondary phases (particles, precipitates), but also shows the potential to expand the limits of applicability of this method for analyzing the morphology and dimensional distribution of pores/microcracks that originated both during casting and heat treatment and during subsequent operation of the tubing. The SAXS approach was adapted, taking into account the shape of cementites/pores, the relationship and ordering of cementites/pores in three-dimensional space, the factor of scale and absorption, analyzed volume and background radiation when processing scattering curves. The analysis of the scattering curves obtained on the transmission  revealed cylindrical cementites with a diameter of 26 nm and a length of 180 nm, as well as manganese sulfides of an elliptical shape. Analysis of scattering curves measured in reflection mode has been shown to detect cylindrical nanopores/microcracks 36 nm in diameter and 170 nm in length, as well as spherical macropores 700 nm in diameter. To validate the obtained data, microstructure studies were carried out by scanning and transmission electron microscopy methods, which showed a convincing convergence of results between them.

Such solutions provide a low-cost means of communication with the physical world and can have applications in areas as diverse as security, production management, research and environmental monitoring. We outline the challenges of system design for a distributed sensor network in which each node has a limited power source and communication channel. The nodes must establish a synchronous network with multiple hops, determine locations, and communicate for purposes such as relaying a signal and transmitting data to a server device. The confluence of low-cost wireless, computing, and sensors has created a new generation of smart devices. The use of tens and thousands of such devices in self-organizing networks has led to the creation of a new technology called wireless sensor networks. In this article, we will consider an example of the use of such a network based on the Bluetooth Low Energy (BLE) wireless data transfer protocol, which gave a serious impetus to the development of wireless sensors. Together with organic polymers, which are used as a sensor layer, it is possible to achieve high energy efficiency and selective sensitivity in monitoring. It is also worth noting the fast and cheap production of electronics based on organic polymers. Due to the semiconductor and flexible properties of organic semiconductor materials, flexible organic electronics has become the core of our technology. The field of organic electronics is entering a commercial phase. The appearance on the market of the first prototypes based on organic transistors made from solutions is intended to expand the existing presence in the market of organic electronic devices. We'll look at some of the key performance requirements for working devices.

In order to eliminate the influence of the viscous instability factor on the motion of the displacement front, the processes of displacement of a less viscous fluid by a more viscous one were studied. \u0000It has been established that non-equilibrium capillary phenomena manifest themselves most intensively in reservoirs with a heterophilic surface, where capillary forces can initiate or block fluid flows between differently permeable interlayers. It has been experimentally shown that in layered-heterogeneous reservoirs with a heterophilic filtration surface in the interlayers, capillary phenomena largely determine the nature of the movement of the fluid displacement front (from the almost complete suppression of the “run-up” of the displacement fronts in the interlayers to the formation of an advanced front in the low-permeability interlayer). In order to exclude the influence of errors of a systematic or random nature on the results of the experiments, their reproducibility and the significance of differences were assessed using the statistical criteria of Student and Cochran, which showed the reliability of the above conclusions. \u0000The results obtained indicate the dominant effect of crossflows between interlayers on the formation of the displacement front of immiscible fluids in layered-heterogeneous reservoirs, especially with a heterophilic wettability characteristic, as well as the possibility of controlling this process by means of physicochemical modification of the wettability conditions of the filtration surface, for example, using surface active substances (surfactants) of various nature and structure.","PeriodicalId":9748,"journal":{"name":"Chemical and Petroleum Engineering","volume":"121 1","pages":""},"PeriodicalIF":0.3,"publicationDate":"2023-08-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89875643","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

But despite a wealth of experience in the use of hydrochloric acid treatments, the results of treatments often do not reach the planned values of oil production growth. Efficiency of acid exposure depends on the depth of penetration of the hydrochloric acid solution into the thickness of the productive reservoir, which, in turn, is conditioned by the degree of reactive activity of the acid composition. It is important to achieve the creation of filtration channels in the zone remote from the borehole, which will lead to an improvement in the filtration characteristics of the bottomhole formation zone to the proper extent. Therefore, in order to achieve the best result when planning acid exposure, it is important to consider the geological and physical properties of the object to be treated and select the appropriate formulation of the acid composition. \u0000The reaction rate constant is a parameter that allows you to take into account the compatibility of the acid composition and the geological and physical conditions of the productive reservoir. This parameter characterizes the rate of reaction between substances. However, a generally accepted method for studying the kinetic parameters of the reaction of acid compositions with carbonate formation rock has not yet been developed, which leads to low reproducibility of experimental results. The purpose of the research presented in the article is to develop a methodology for studying the kinetics of the reaction of hydrochloric acid with carbonate rock and to create a unified approach to determining the reaction rate constant, characterized by the greatest reproducibility of the results. The experimental part of the work was carried out in several stages, including the preparation of core material, the preparation of hydrochloric acid solution and its thermostating, and the further conducting of four series of studies at the PIK-OSG volumetric setup to determine the optimal acid-rock ratio, identify the optimal weight of the core material and establish the optimal coarseness of its grinding. \u0000The obtained results of experiments on the study of methodological aspects of the study of the rate constant of the reaction of hydrochloric acid with carbonate rock showed that the experiments should be conducted in conditions of an excess of rock relative to acid, in this case the mass of the core sample and the coarseness of the grinding of the core material will not affect the error in determining the reaction rate constant.","PeriodicalId":9748,"journal":{"name":"Chemical and Petroleum Engineering","volume":"12 1","pages":""},"PeriodicalIF":0.3,"publicationDate":"2023-08-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89006270","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The relevance of this topic is justified by an increase in the volume of associated petroleum gas (APG) production and, accordingly, the damage caused to the environment due to its combustion. In addition, insufficient financial investment hinders the successful development of innovative economic schemes such as industrial symbiosis. \u0000The methods of APG disposal and processing used at present were analyzed, the negative consequences of combustion, sanctions imposed by the state and restrictions on their application were investigated.
