This study investigates the electrokinetic properties of reservoir fluids and fluid discharge behavior under varying pressure conditions in the presence of magnetic fields.</p> <p><strong>Aim: </strong>The primary aim of this study is to investigate the effects of magnetic fields on the electrokinetic properties of reservoir fluids and their fluid discharge behavior under varying pressure conditions. By conducting comprehensive experimental analyses, the research seeks to determine the optimal magnetic field intensity that enhances fluid conductivity, ion mobility and water displacement efficiency. The study also aims to evaluate the role of magnetic fields in mitigating pressure-induced compaction in porous media and establishing stable fluid flow conditions. The findings are expected to contribute to the advancement of enhanced oil recovery (EOR) techniques by integrating magnetic field technology to optimize oil field development, particularly in mature and low-permeability reservoirs.</p> <p><strong>Materials and methods:</strong> A custom experimental setup, including a high-pressure column, PVT bomb, electromagnet, measurement and control devices was developed to simulate reservoir conditions. Magnetic field intensities ranging from 40 to 150 mT were applied to study their effects on voltage, resistance, and water discharge during pressure variations (1.6–14.4 atm).</p> <p><strong>Results: </strong>The application of magnetic fields significantly enhanced the electrokinetic properties of reservoir fluids. At an optimal intensity of 125 mT, ion mobility and fluid conductivity were maximized, leading to a peak water discharge volume of approximately 75 m³ at 8–9 atm. Beyond this pressure, a dynamic equilibrium stabilized fluid flow. Resistance and voltage values decreased substantially under magnetic fields, highlighting their role in mitigating pressure-induced compaction in porous media.</p> <p><strong>Conclusion:</strong> This study demonstrates the transformative effects of magnetic fields on the electrokinetic properties and discharge behavior of reservoir fluids. The optimal magnetic field intensity of 125 mT enhanced ion mobility, fluid conductivity and water discharge, achieving a peak discharge volume of approximately 75 m³ at 8–9 atm. These findings emphasize the role of magnetic fields in reducing flow resistance and stabilizing fluid flow under high-pressure conditions, particularly by mitigating pressure-induced compaction in porous media. Additionally, the observed dynamic equilibrium beyond 8 atm suggests that magnetic fields can maintain fluid conductivity and discharge stability despite increasing pressures. These advancements pave the way for employing magnetic field technology to enhance oil recovery, especially in challenging environments such as mature or low-permeability reservoirs.</p>magnetic fieldreservoir fluidselectrokinetic propertiesenhanced oil recoveryporous mediawater dischargeresistancevoltageмагнит өрісіқабат сұйықтықтарыэлектрокинетикалық қасиеттерімұнай берудің жоғарылауыкеуекті ортасу разрядыкедергікернеумагнитное полепластовые жидкостиэлектрокинетические свойстваповышение нефтеотдачипористые средыразряд водысопротивлениенапряжение1.Мирзаджанзаде А.Х., Искандаров М.А., Абдуллаев М.А.
