Cement sheath integrity is a critical element to maintain over the life of a well to prevent/minimize Sustained Casing Pressure (SCP), Surface Casing Vent Flows (SCVF) and gas migration. The key to successful models is to combine the life cycle/stresses of the well with the cement mechanical properties to provide cement systems that will withstand the wellbore stresses.
