· During the drilling process, many operations will cause cyclic loading of the wellbore, including surge/swab pressure generated by tripping operations and pressure fluctuations induced by shutdowns/startups of the mud pumps. With cyclic loading, the wellbore rock may fail even if the stress level is lower than the predetermined static rock
