Sustainable foam stabilization using red mud-derived nanoparticles for enhanced oil recovery and CO₂ sequestration.

ABSTRACT: Foam has been widely used for enhanced oil recovery (EOR) and CO₂ sequestration due to its ability to improve sweep efficiency and control gas mobility. However, foam instability poses challenges for long-term applications. While nanoparticles have been explored as foam stabilizers, their high cost and limited availability hinder large-scale use. This study investigates red mud-derived nanoparticles (RMNPs), synthesized from industrial waste, as an affordable and sustainable alternative to traditional foam stabilizers. RMNPs were produced by ball milling at varying milling durations, achieving sizes below 200 nm. Characterization of the RMNPs was conducted using scanning electron microscopy (SEM), energy-dispersive X-ray spectroscopy (EDX), zeta potential measurements, and parti
