A detailed analysis of chemical reagents that are used in visbreaking units at oil refineries is presented. Additives have been identified that are used in a number of refineries, such as a passivator, coke inhibitor, dispersant, corrosion inhibitor, neutralizer, defoamer or antifoaming agent. The most vulnerable points of the visbreaking installation technology are considered. A diagram is presented with the designation of areas with possible problems, namely foaming of the oil product, contamination by coke deposits of equipment, corrosion of helmet lines, the possible formation of hydrogen sulfide and other undesirable components. A comprehensive review of each reagent allows you to understand its purpose at the facility, to understand the mechanisms of the action of reagents. The approximate compositions of each reagent are analyzed, the requirements for additives are considered.

In this article, based on determining strain parameters such as the equivalent (von Mises) strain and average strain, calculations of the depth growth rate of fatigue and stress-corrosion cracks as well as the operating life of the pipeline sections are performed. The results are presented as the operating time to failure and cycles number to failure by loading internal pressure. The obtained graphs of the dependence of the crack growth rate, crack depth, equivalent (von Mises) strain, average strain in the defective zone on the pipeline operation time are presented. During computational experiments for the main pipeline the destructive depth of defects, the residual operating life of the pipeline with cracks having different initial depth and length were determined.

The studies described in the article show that the by-product of oxidative desulfurization of low-viscosity marine fuel is a promising inhibitor of acid corrosion, showing anticorrosive activity in dimethylformamide medium with respectto carbon steel grade St3sp with a degree of protection of 75.5%. This will not only simplify the material support of the proposed alternative technological process of desulfurization of fuel and solve environmental problems, but also reduce the need of the domestic industry for expensive imported reagents.

The purpose of this article is to deduce the dependence of the hydraulic efficiency of drag-reducing agent on real objects on the hydraulic efficiency of drag-reducing agent in bench or laboratory conditions for two cases: smooth and rough pipeline wall. The method used in this article is a mathematical analysis of the dependenciesof the efficiency of drag-reducing agent in pipelines of different diameters with different roughness of the pipeline wall.This article analyzes the dependencies for calculating the coefficient of hydraulic resistance during flow in pipelines of various diameters. The dependence of the hydraulic efficiency of the drag-reducing agent on the diameterof the pipeline is analyzed. In the course of transformations, including using the Lambert function, an explicit dependence of the hydraulic efficiency of drag-reducing agent under conditions of different diameters for smooth pipes and an implicit dependence for rough pipes was revealed.

In this paper, a new mathematical model of unsteady flow of a naturally fractured porous medium is presented,in which artificial fractures intersecting a vertical well and three different geometries of pore blocks containing plates, cylinders and spheres were considered. A new solution was obtained using the Laplace transform and an integral approach using the point source function. A polar coordinate transformation was used to process the radial distribution of an arbitrary number of cracks and angle. The model was then tested against three published cases.

This article describes the methodology and results of studies to assess the distribution of residual water saturation in real core samples using X-ray computed tomography. The algorithm for determining residual water saturationis based on the analysis of integral intensities of absorption spectra, which is also used in other methods of studying the chemical composition of a substance, for example, infrared spectroscopy, nuclear magnetic resonance.This technique has been tested on standard petrophysical samples of terrigenous and carbonate deposits, characterized by various filtration-capacitance properties and collector type. The developed technique made it possible to determine the distribution of residual water in core samples, which can serve as additional information for development engineers of oil and gas fields.

The paper considers the issues of applying 2D and 3D modeling methods to justify the boundariesof the Qishn formation based on a set of seismic data for the Tawila field (Republic of Yemen). The proposed algorithms and approaches to identifying reservoir boundaries and subsequent modeling of the Qishn formation reservoir make it possible to assess not only the structure of the oil-saturated part, but also to assess the possibility of detecting promising oil production zones for the territory of neighboring fields, as well as oil-bearing formations in the upper and lower formations.

The possibility of saving energy resources in the transport of natural gas is considered - one of the most energy- consuming resources, which is characterized by large losses of energy used. The proposed technical solution is based on the use of an expander generator set in the fuel and pulse gas preparation unit. Using the example of a compressor station, a scheme is proposed for installing an expander-generator unit (DGA) in the fuel gasreduction unit, with the help of which additional electricity and cold can be generated. At the same time, the heat of the cooled air is not discharged into the environment, that is. the operation of the installation is characterized by high environmental indicators. The paper presents the technical characteristics of the DGA used, as wellas the calculation of economic efficiency.
