Abstract Underground storage of carbon dioxide (CO2) and hydrogen (H2) in geological formations has been considered an effective method for the energy transition towards a low-carbon industry. The wettability rock is significant parameter underground gas storage, determining both capacity containment safety. This study focuses on using two chemicals, methyl orange (MO) methylene blue (MB), as wetting agents at different concentrations (10 to 100 mg/L) change improve CO2 H2. To achieve this, contact angle measurement technique was utilised measure advancing (θa) receding (θr) angles under reservoir conditions, with constant pressure 13 MPa system 20 system, temperatures 25°C 50°C, brine salinity 0.3 M NaCl. mimic surfaces calcite quartz samples were treated stearic acid before being exposed agent chemicals. Although these are hydrophobic, modifying their even very trace concentration MO or MB significantly alters from hydrophobic hydrophilic. demonstrates that presence organic acids can affect H2 rock. However, injecting diluted amount into sandstone carbonate increase capacity.

The distribution OHCs at pore scale, capacity these reservoir security their confinement are all greatly affected by interfacial properties. These variables include equilibrium contact angle (θE), tension (IFT) between solid brine phase (γSL) (γsohc). Nevertheless, due technological limitations associated with experimentally obtaining parameters, they frequently computed using Young’s equation Neumann’s state.
