1. A method for predicting annular fluid expansion (“AFE”) within a borehole using a processor, the method comprising:
defining a configuration of the borehole, wherein the borehole configuration comprises multiple sealed casing string annuli; then
defining a simulated production operation and a simulated borehole operation that would be performed before the simulated production operation; then
predicting, with the processor a first AFE within each of the multiple sealed casing string annuli associated with the simulated production operation; then
predicting, with the processor, a second AFE within each of the multiple sealed casing string annuli associated with the simulated borehole operation based on the predicted first AFE within each of the multiple sealed casing string annuli; and
outputting the second AFE within each of the multiple sealed casing string annuli associated with the simulated borehole operation to a display.
