Claim 3:
4. The method of claim 3, wherein predicting the second AFE within each of the multiple sealed casing string annuli further comprises:
determining a change in a fluid volume of a fluid within the sealed casing string annulus based on the predicted first AFE within each of the multiple sealed casing string annuli, a temperature, a pressure, and an applied pressure change; then,
determining a change in a casing volume based on the change in the fluid volume and a casing deformation associated with the simulated production operation; then
determining annular pressure build-up within the sealed casing string annulus; and then
repeating the steps of determining the change in the fluid volume, determining the change in the casing volume, and determining the annular pressure build-up until global pressure equilibrium is reached.
