Oscillatory injection can delay particle clogging in porous media by disrupting deposit formation. However, its effectiveness depends on fluid salinity and particle interactions, with higher frequencies sometimes accelerating blockage under certain conditions.

Area of Science:

  • Geosciences
  • Fluid Dynamics
  • Colloid Science

Background:

  • Particle deposition and clogging in porous media significantly impact groundwater filtration, geothermal energy, and subsurface fluid management.
  • Declining permeability and blocked flow pathways necessitate effective mitigation strategies for sustained operation.

Purpose of the Study:

  • To investigate how oscillatory flow affects particle transport and clogging in complex, tortuous porous media.
  • To understand the influence of physicochemical conditions and flow frequencies on clogging dynamics.

Main Methods:

  • Microfluidic experiments using colloidal suspensions.
  • Application of controlled oscillatory flow over various frequencies.
  • Monitoring of permeability evolution and particle deposition.

Main Results:

  • Under saline conditions, increasing oscillation frequency delayed clogging and increased injected volume.
  • Decreasing ionic strength altered the clogging mechanism, with high frequencies accelerating blockage.
  • Oscillatory flow's effect on clogging is regime-dependent, influenced by hydrodynamic forces and particle interactions.

Conclusions:

  • Oscillatory injection is not universally beneficial for preventing clogging; its impact is contingent on specific environmental conditions.
  • Understanding the interplay between flow oscillations and particle behavior is crucial for optimizing fluid management strategies in porous media.
