Mitigation of fine migration in low salinity water flooding of clay-rich sandstones Using Fe₃O₄/Saponin/Cu(II) nanocomposite

Key Points

• Fine migration is significantly mitigated using a nanocomposite approach with Fe₃O₄ and saponin.
• The study reports a reduction of fine migration by 50% in scenarios with low salinity flooding.
• Assessment using experiments on clay-rich sandstone indicates enhanced stability with the Cu(II) nanocomposite.
• This highlights the potential of nanocomposites in optimizing water flooding techniques for oil recovery.
