This study presents the development and comprehensive evaluation of an innovative ternary-component nanofluid system, meticulously engineered through the synergistic combination of functionalized nanoparticles, surfactant molecules, and hydrophilic polymers. This novel formulation represents a significant advancement in chemical enhanced oil recovery technology, designed to concurrently address multiple recovery-limiting mechanisms including unfavorable wettability and inadequate oil recovery in challenging reservoir environments. The synthesized hybrid nanofluid underwent exhaustive experimental characterization to establish its performance metrics across all relevant EOR mechanisms. A multi-faceted experimental protocol was employed, incorporating high-resolution contact angle measurements for wettability quantification, precise interfacial tension analysis via the pendant drop technique, and dynamic core flooding experiments under representative reservoir conditions at 80°C. Comprehensive stability assessments were conducted through zeta potential measurements and time-resolved gravimetric analysis to evaluate sedimentation behavior and colloidal integrity.
