Effective coating of nanoparticles on the proppant pack has been regarded as a promising technique for enhancing proppant functions to achieve multiple objectives. In this work, a dynamic soaking technique which we refer as “pseudo-continuous fixed bed (PCFB)” adsorption has been employed for the first time for coating of four bare NPs (Al₂O₃, SiO₂, MgO, ZrO₂) with divergent physical and chemical properties, onto a fixed adsorbent glass bead proppant pack. A systematic study of the formulated nanofluid (brine+NPs) adsorption onto the proppant pack was conducted vis-à-vis salinity (0 to 10.5 wt% NaCl), temperature (298.15 to 348.15 K), NPs loading (0.01 to 0.2 wt%), and injection rates (1 to 50 mL.min⁻¹). Nanofluid stability was measured via zeta-potential measurements, where NP adsorption was verified through optical microscopy and atomic force microscopy. Results show that PCFB adsorption of NPs …
