Abstract
Methods of the present disclosure relate to assessing and mitigating the risk of pore pressure buildup as part of designing a cement formulation. A method comprises: performing wellbore integrity analysis to provide a stress state of a cement sheath, wherein the cement sheath is a model; modifying the stress state of the cement sheath due to fluid influx through the cement sheath; comparing the modified stress state to failure properties for the cement sheath; and formulating a cement composition based on at least the modified stress state.
