Numerical Simulation of Wellbore Closure Due to Shale Creep-Part I: A Poro-visco-elastoplastic Approach

Key Points

• Wellbore closure occurs due to significant shale creep over time, impacting drilling stability.
• The study specifically highlights a poro-visco-elastoplastic approach to geomechanical modeling.
• Assessment of wellbore behavior under various conditions helps in predicting closure scenarios effectively.
• The findings underscore the need for further investigation into shale behavior under operational stresses.
