Iyer & Smith (2024): Impact of cement composition, brine concentration, diffusion rate, reaction rate and boundary condition on self-sealing predictions for cement-CO2 systems

Jaisree Iyer, Megan M. Smith IN: International Journal of Greenhouse Gas Control, 134, 104126, https://doi.org/10.1016/j.ijggc.2024.104126

Here the authors examine the sensitivity of our model, describing CO2 leakage through wellbores, to cement composition, brine concentration, diffusion rates, and reaction rates. They also evaluate the impact of the boundary condition to allow comparisons between observations from experiments performed at constant flow rate and model predictions made at constant pressure conditions. The results show that diffusion and reactions rates have the most impact on the self-sealing criteria for cement-CO2 systems.
