- •
Gas breakthrough experiments were conducted using CO2, N2 and CH4 gases.
- •
Capillary sealing efficiency of shale was determined as a low quality seal.
- •
The anhydrite caprock is appropriate for long term safety of underground CO2 storage.
- •
Seal samples showed a better sealing performance for CH4 rather than N2 and CO2.
- •
Low effective permeability of gas was measured at high capillary breakthrough pressure.
