This paper analyzes the flow behavior of gas – liquid mixtures in pipelines and reviews modern approaches to hydraulic calculations of two-phase flows. The main hydrodynamic and thermodynamic factors affecting the transportation of gas, oil, condensate, and wa...
This article presents the results of a comparative analysis of occupational safety culture in small enterprises of Uzbekistan across different sectors. The study was conducted in 2023 – 2025 in enterprises operating in Kashkadarya region within three sectors: ...
Abstract. Cotton processing waste (husks and stalks) in Uzbekistan represents a significant renewable raw material for lignin production, the basis of thermo- and salt-resistant drilling fluid reagents. The choice of lignin extraction method affects its purity...
The article presents the results of a 3D geological model of the Sherkent oil and gas field, created using Schlumberger’s Petrel software. The Sherkent structure was prepared for exploratory drilling in 2007 based on the interpretation of 3D seismic survey dat...
The paper presents the results of studying the fracturing and reservoir properties of rocks based on well logging data. Standard well logging methods (WLM – acoustic, neutron - gamma, gamma - gamma density, electrical and induction logging) were used to determ...
The article analyzes issues related to improving the operational reliability of centrifugal pumps widely used in the mining industry. It has been established that the primary causes of failures in pumping equipment operating in hydrotransport systems are hydro...
This article analyzes the effect of pressure (0.1 – 100 MPa) and temperature (20 – 250°C) on the properties of technological fluids (HCl, water) and reaction products ( 𝐶𝑎𝐶 𝑙 2 , 𝑀𝑔𝐶 𝑙 2 , 𝐶 𝑂 2 , 𝑁 2 ) during acid treatment of carbonate reservoirs. Studies sh...
The article presents the results of studying the conditions for well gushing in oil and gas condensate fields under development systems with priority oil extraction and gas cap gas conservation, as well as the joint operation of the oil and gas condensate part...
Using the central part of the Chardzhou stage as an example, the results of zoning the territory by the ratio of structural plans of carbonate and terrigenous deposits are presented, with the identification of 9 types of zones in the paper. Based on the analys...
This article examines the issues of improving the efficiency of chemical treatment of productive formations in oil and gas wells. Due to the shortage of hydrochloric acid and the increase in its cost, the possibility of using phosphoric acid for treating produ...
This article analyzes the production technology of sulfur-based polymer concrete and its environmental efficiency. Compared to traditional cement-based concrete, the manufacturing process of sulfur polymer concrete significantly reduces carbon dioxide (CO₂) em...
This study focuses on the analysis of the control system for the roasting process of sulfide-containing products. The physico-chemical characteristics of the process are examined, including temperature regulation, oxygen concentration, and gas flow stability. ...
The near-wellbore zone of reservoirs of various types is characterized by complex physical and chemical processes that determine well productivity and the efficiency of stimulation methods. This study examines three independent directions of near-wellbore tran...
This paper presents an integrated analysis of geological field data and the current development status of the Shortak gas-condensate field. Through interpretation of hydrodynamic well test results, reservoir filtration parameters were determined, including the...
The near-wellbore zone of reservoirs of various types is characterized by complex physical and chemical processes that determine well productivity and the efficiency of stimulation methods. This study examines three independent directions of near-wellbore tran...
This article analyzes the conditions and criteria for selecting the optimal absorbent or the type of combined absorbents for the selective purification of natural gas from acidic components and sulfur-containing compounds, as well as the challenges associated ...
The article presents the results of the author's research on the use of resource-saving technologies and technical means for gas production and transportation through pipelines, as well as their purification from foreign impurities. Considering that 75% of all...
The results of evaluating the oil displacement coefficient by water, based on actual field development data from oil reservoirs in the Bukhara - Khiva region, which is represented by clastic rocks, are presented. A wide range of variations in the achieved valu...
Hydrogen is of great interest as a carrier of clean energy in the global transition to renewable energy sources. Uzbekistan is distinguished by its high solar radiation; therefore, it offers a wide opportunity in the production of hydrogen from solar energy. I...
The agrotechnical and energy performance of the ripper plough for non-tillage depends largely on the relative position of the roller and the last working body with an inclined rack. The purpose of the study is to substantiate the longitudinal distance between ...
