In this study, the mixture of the surfactant, nanoparticles and brine are utilized to investigate the performance for the interfacial tension reduction and contact angle changes at various conditions. From the results, IFT decreased adversely with brine content, whereas the nanoparticles even increased IFT when in used alone in the system. In addition, the temperature and the surfactant concentration have the effects on IFT, and nanoparticles are also the key contributor of ultra-low IFT reduction with the mixture of the surfactant-brine system. Meanwhile, without even the ion changes, the brine can affect the contact angle changes between crude oil and solid surface.
Key words: SDS / Silica Nanoparticles / Low salinity / IFT and contact Angle Reduction
