Mitigating CO2 Leakage by Immobilizing CO2 into Solid Reaction Products: 13th International Conference on Greenhouse Gas Control Technologies, GHGT 2016. 14 November 2016 through 18 November 2016

In the unlikely case of CO2 leakage from a storage reservoir, it is desirable to close the leak efficiently and permanently. This could be done by injecting a reactive solution into the leak path, thereby immobilizing migrating CO2 by consuming the gas and forming solid reactants. With regard to permanent closure, it is important to consider...

Model calibration on cement experiments at realistic CO2 storage conditions

Large scale implementation of CO2 storage can significantly reduce emission of greenhouse gasses into the atmosphere. However, safe and long-term containment of CO2 in storage reservoirs must be ensured. Wellbores in the subsurface present possible leakage pathways for CO2 to the surface and hence wellbore cement reactivity is of major concern....
