Chemical and Mechanical Properties of Wellbore Cement Altered by CO^sub 2^-Rich Brine Using a Multianalytical Approach

Defining chemical and mechanical alteration of wellbore cement by CO2-rich brines is important for predicting the long-term integrity of wellbores in geologic CO2 environments. We reacted CO2-rich brines along a cement-caprock boundary at 60 °C and pCO2 = 3 MPa using flow-through experiments. The re...
