Transient Stress Distribution and Failure Response of a Wellbore Drilled by a Periodic Load

Transient Stress Distribution and Failure Response of a Wellbore Drilled by a Periodic Load

The poroelastodynamic failure of a wellbore due to periodic loading during drilling is an unsolved problem. The conventional poroelastic method to calculate the stress distribution around wellbore is for static loading cases and cannot be used for short-time dynamic-loading cases which result in wav...
