This paper addresses alkaline sodium silicate (Na-silicate) behavior in porous media. One of the advantages of the Na-silicate … system is its water-like injectivity during the placement stage. Mixing Na-silicate with saline water results in metal … silicate precipitation as well as immediate gelation. This work demonstrated that low salinity water (LSW, sea water diluted 25 …
