This study demonstrates a sustainable, "trash-to-treasure" approach by synthesizing silica (SiO2) and alumina (Al2O3) nanoparticles (30–80 nm) from local waste materials—specifically bentonite clay and aluminum wire waste—and evaluating their performance as eco-friendly additives in 350 mL water-based drilling fluids at concentrations ranging from 0 to 1 g. Tested under harsh subsurface conditions, the incorporated nanoparticles significantly enhanced the fluids' rheological properties, lubricity, filtration control, and swelling inhibition, with performance scaling alongside nanoparticle concentration. Notably, at a 1 g dosage, the fluid's yield point spiked from a baseline of 9 to 42 for SiO2 and 32 for (Al2O3), while high-pressure high-temperature (HPHT) fluid loss was reduced from 21 mL to 14.6 mL (SiO2) and 16.4 mL (Al2O3) due to the formation of a low-permeability filter cake. Furthermore, a 0.75 g dosage lowered the coefficient of friction from 0.45 to 0.35 (SiO2) and 0.37 (Al2O3), while effectively mitigating clay swelling (SiO2) showing superior inhibition at lower concentrations), ultimately proving that these waste-derived nanoparticles offer a highly effective, cost-efficient, and environmentally friendly alternative to commercial drilling mud additives.
