Investigation of fluid dynamics impact with magnetic field applications on enhanced oil recovery in porous media

This study investigates the impact of magnetic fields on the electrokinetic properties of reservoir fluids and fluid discharge behavior under varying pressure conditions. A custom experimental setup was developed, comprising a high-pressure column, PVT bomb, electromagnet and multiple measurement and control devices, to simulate reservoir conditions accurately. The study systematically examined the influence of magnetic field intensities ranging from 31831 to 119366 A/m on voltage, resistance and water discharge across pressure variations between 1.6 and 14.4 atm. The results demonstrate that magnetic fields positively influence fluid behavior, significantly enhancing ion mobility and fluid conductivity. This enhancement leads to increased water discharge and stabilized fluid flow, particularly under high-pressure conditions. Notably, an optimal magnetic field intensity of 99472 A/m was identified, yielding the most favorable effects on reducing resistance, stabilizing voltage and increasing discharged water volume. At this intensity, the resistance of the system decreased significantly and the discharged water volume peaked at approximately 75 m³ around 8- 9 atm, highlighting the field's role in facilitating fluid movement through porous media. Beyond this intensity, a diminishing return effect was observed, indicating a potential saturation point in the magnetic field's influence on fluid properties. These findings provide valuable insights into the role of magnetic fields in optimizing fluid transport in porous media, offering potential advancements for enhanced oil recovery techniques. The study underscores the transformative potential of magnetic fields in improving fluid mobility and recovery efficiency in oil reservoirs, paving the way for further exploration and application of this technology in the oil and gas industry.
