Corrosion of Cement by Carbonated Brine

    One component of the program to reduce CO2 in the atmosphere is to inject it into deep aquifers where it will remain for centuries or longer. The Carbon Mitigation Initiative at Princeton University addresses many aspects of the greenhouse gas problem, ranging from climate modeling, to the economics and technology for carbon capture, to injection and storage. Our piece of the problem is to study the mechanisms by which CO2 could escape through abandoned oil wells that penetrate the zone in which the gas is stored. We have studied the rate of corrosion of cement by carbonated brine, in work initiated by Andrew Duguid (now working for Schlumberger) and extended by Ed Matteo. A model for the reactive transport process has been developed (primarily by Bruno Huet (now working for Schlumberger) and Prof. Jean Prévost) that provides accurate predictions of the rate of attack.
