Background: During deep drilling of oil and gas wells, the dynamic instability of the drill string caused by radial and axial vibrations of the drill bit leads to a reduction in the rate of penetration (ROP), increased tool wear, and deterioration of the wellbore gauge. This problem becomes particularly pronounced when drilling formations with alternating lithology and rock strength. An analysis…
This article examines problems associated with the quality of cementing and casing integrity in oil and gas wells under conditions of increasing drilling activity in Kazakhstan. It is shown that complications such as behind-casing hydrocarbon migration, sustained casing pressure, and water coning are largely caused by poor cementing quality and the loss of wellbore integrity. It is noted that more…
Background: Conventional waterflooding typically achieves an oil recovery factor of no more than 35–40%, leaving a significant portion of the oil in place within the pore space of the reservoir rock, where it is retained by capillary forces. The application of chemical enhanced oil recovery methods, particularly Alkaline–Surfactant–Polymer (ASP) flooding, is a promising approach for high-viscosity…
Background: The problem of internal corrosion in oil and gas pipelines remains one of the key challenges in ensuring industrial safety and reliable operation. Conventional monitoring methods, such as gravimetric and electrochemical techniques, provide only average corrosion rates and do not account for localized areas of accelerated metal loss or the influence of erosion. Therefore, the…
Amid the digital transformation of the global economy, Big Data analytics and advanced analytics technologies are becoming key tools for enhancing business efficiency and sustainability. Their application is particularly relevant in the capital-intensive and high-risk oil and gas industry, where data-driven decision-making offers significant competitive advantages. This study examines the…
Background: In recent decades, artificial intelligence technologies (hereinafter – AI) have been rapidly integrated into the oil and gas industry, covering key stages of geological exploration, geophysical data interpretation, reservoir modeling, and field development. Modern methods of big data analysis, machine learning, and intelligent control systems make it possible to improve the accuracy of…
Background: Correct identification of the fluid phase state (oil or gas condensate) at the Eastern Urikhtau field is critically important for reliable reserve estimation and the selection of an appropriate development strategy. Anomalously highgas-oil ratio values in wells EU-6 and EU-7 (up to 1000 m³/m³) as well asdiscrepancies between the hypsometric levels of the presumed gas-oil contact and…
Background: High water cut increases operating costs and reduces oil recovery. Gravity-driven redistribution of oil and water during well shut-in periods has been proposed for reducing water cut; however, laboratory methodologies for investigating this phenomenon in core samples remain limited. Aim: To develop a laboratory methodology for evaluating gravity segregation in oil–water saturated cores…
This study examines the thermal treatment of polystyrene waste as an effective alternative to conventional mechanical recycling. Given the growing volume of plastic waste and the complexity of processing foamed materials, an analysis was conducted of recent publications on the influence of process parameters on the yield and composition of liquid pyrolysis products. Particular attention was paid…
The gradual tightening of environmental standards, combined with growing global demand for environmentally friendly fuels, has significantly increased the importance of advanced technologies in oil refining. In this context, the catalytic isomerization of light alkanes (C₄–C₆ fraction) is one of the most strategic processes for improving gasoline quality without increasing the concentration of…
