Abstract
Supercritical carbon dioxide (Sc-CO2) has been used in shale gas exploitation for efficient fracturing and the added benefit of CO2 geo-storage. Many studies have suggested that the water wettability of shale significantly influences the success of shale gas recovery. The aim of this work was to investigate the effect of CO2 treatment on shale water wettability. X-ray diffraction (XRD) analysis, Fourier transform infrared spectroscopy (FTIR),...
