This work addresses the influence of buffered sodium silicate, (SiO2)3.35Na2O, on water-oil displacement efficiency in quartz media using static and flooding experiments. IFT measurements reveal that sodium silicate-oil interfacial tension is a...

fingerings, with characteristics corresponding to the experimental observations. The effects of wettability, viscosity ratio and interfacial tension were investigated. In strongly water-wet matrix, with grain contact angles of θ<π/8, different micro...
