Implications of Wettability Alteration of Sandstone Rocks Using Non-fluorinated scCO2-based Silylation

Abstract

This research has compared the multiphase flow characteristics of the CO2-brine-rock system under the strongly water-wet and CO2-wet states. It has also developed a novel scCO2-based silylation technique that can be used to induce the necessary wettability alteration to sandstone rocks. This research serves to fill an existing gap in the published literature by providing reliable experimental evidence about the effect of wettability on dynamic multiphase flow characteristics of CO2-brine system.
