Abstract
A method to design a wellbore cement sheath in compacting or subsiding formations is provided. The method may include performing a field scale analysis on a formation surrounding a wellbore. The field scale analysis may output boundary conditions including a pore pressure of the formation and a three-dimensional movement of the formation. The method may also include performing a wellbore scale analysis based on the boundary conditions, a wellbore scale model, wellbore conditions, and cement material properties. The wellbore scale analysis may output an indication of stress applied over time to a cement sheath within the wellbore. Further, the method may include determining cement material properties of the cement sheath to withstand the stress applied over time output by the wellbore scale analysis, and the method may include installing the cement sheath within the wellbore. The cement sheath may include the cement material properties.
