Wells remain inadequately studied with respect to the probability and rate of leakage in geologic CO2 sequestration. Efforts to model reaction-induced leakage along wells have been limited due to poorly understood reaction between cement and sequestered CO2 fluids. Recent work on class H cement unde...
