Nowadays, novel silicon quantum dots (SiQDs) are applied in various aspects of the petroleum industry, especially enhanced oil recovery (EOR). Herein, amphiphilic (ASiQDs) were synthesized to improve stability foam formed by nonionic surfactant polyethylene glycol monoisodecyl ether (PMIE). The greater and resistance stabilized 0.05% PMIE-0.1% ASiQD system compared other systems (including pure PMIE conventional silica nanoparticles (SiNPs)–PMIE systems) confirmed relative volume measurement, half-life Turbiscan Laboratories expert analysis, observation morphology. Based on dynamic surface tension modulus measurements, promising was attributed rigid film generated largely adsorbed ASiQDs with tiny size moderate hydrophobicity. more intensive electrostatic repulsion among smaller bubbles, significantly preventing coalescence. Finally, sandpack flooding results suggested PMIE-0.1%ASiQD could efficiently plug high permeability pore throats evidently 21.2%. report employed efficiency for EOR.
