  • Can silica nanofluids be used in oilfield polyacrylamide?
  • Liq. 248, 153–162 (2017). Sharma, T., Iglauer, S. & Sangwai, J. S. Silica nanofluids in an oilfield polymer polyacrylamide: Interfacial properties, wettability alteration, and applications for chemical enhanced oil recovery.
  • Does colloidal silica nanofluid affect interfacial tension?
  • In this study, colloidal silica nanofluid was synthesized using sodium silicate, and its effect on alteration in interfacial tension of water containing nanofluid and oil, alteration in wettability, secondary and enhanced recovery was assessed.
  • How can nanofluid containing nano-silica be synthesized?
  • First, colloidal nanofluid containing nano-silica was successfully synthesized by using the sol–gel method. FTIR test, particle size, and zeta potential indicated that silica particles are formed in fluid structure, and average particle size falls in nanoscale, and the solution was stable.
  • Are reinforced colloidal silica nanoparticles able to activate interfacial phenomena?
  • This clarified that strongly hydrophilic nanoparticles like silicon oxide are able to activate interfacial phenomena. In conclusion, the reinforced colloidal silica nanoparticles did so through three important EOR mechanisms of mobility control, wettability restoration, and IFT reduction, as illustrated in Fig. 14.
