Supplementary Data for article "Effect of wettability alteration towards gas-wet using surface-modified nanosilica on improving relative permeability and fluids recovery".

Supplementary materials contained data of fluid density and viscosity used in the experimental study (Table S-1) and porosity and permeability of the cores used in the coreflood tests (Table S-2). The experimental study was divided into two parts, i.e. in gas-condensate system and gas-water system. Data of coreflood tests in gas-condensate system were tabulated in Table S-3 through S-7, and its graphical representation in Fig. S-1 through S-5. Meanwhile, data of coreflood tests in gas-water system were tabulated in Table S-8 through S-12, and its graphical representation in Fig. S-6 through S-10.
