Investigation of Well Cement Degradation by Carbonated Brine in Supercritical CO2 Environment

Well cement tends to degrade when exposed to carbonated brine. This study focuses on the chemical alteration of cement by carbonated brine in supercritical condition and to estimate the degradation rate of cement by carbonated brine attack by using Fick’s Law and Elovich equation. Correlation betwee...
