  • Fatigue management extends drill pipe life

    Richard F. Zoanni, S. DeWayne Everage, Thomas M. Wadsworth and Juan P. Cassanelli

    Industry advances continue to enable operators to pursue more challenging drilling targets with complex wellbore trajectories in costly deepwater and/or remote operating areas. Demand for a practical, field-proven drill pipe fatigue management system has grown as drillstring fatigue failures contribute to non-productive time and cost. The response has been the development of an engineered approach that combines pipe section positioning and inspection scheduling, based on estimated fatigue damage rather than rotating hours or footage drilled. Successful real-time field implementation with ongoing drilling programs demonstrates that the cumulative fatigue damage technique is a valuable tool for risk mitigation and cost reduction.
