Effects of Reservoir Pressure and Temperature on CO2-Brine Wettability in Low-Permeability Sandstone: Implications for CO2-Enhanced Oil Recovery and Geological Storage.
Wettability is a key interfacial property affecting CO2-enhanced oil recovery and geological CO2 storage in reservoirs. However, experimental data on the wettability of CO2-brine-rock systems remain limited for low-permeability sandstone, a major lithology in unconventional oil reservoirs. In this study, low-permeabili...
