Interfacial-active green surfactants from sugarcane bagasse and its biochar for enhanced oil recovery.

ABSTRACT: Sugarcane bagasse (SCB), a primary agricultural waste from sugar production, poses significant environmental challenges due to its accumulation. This study introduces the direct application of SCB and its biochar (SCB-B) as cost-effective and eco-friendly agents for Enhanced Oil Recovery (EOR). We systematically investigated their efficacy in reducing oil-water interfacial tension (IFT) and altering the wettability of carbonate rocks. Both materials significantly reduced IFT by up to 70% and shifted strongly oil-wet surfaces towards neutral-wet conditions by up to 47% at very low concentrations. A pivotal finding was the shift in governing mechanisms at the Critical Micelle Concentration (CMC), which increased from 16 ppm in distilled water to 70 ppm in saline environments. Interestingly,
