Field-Proven and Emerging Technologies for Safe, Efficient, and Sustainable Well Abandonment and Decommissioning

Thursday, 7 May
Room 312
Technical Session
This session presents field-proven techniques and new technologies improving the safety and cost-effectiveness of well abandonment and decommissioning. Topics include thru-tubing cement barrier evaluation, hydraulic disconnect plug applications, and conductor removal innovations. Additional papers introduce modeling tools for plug performance and sustainable materials such as poromechanical cements and machine-learning-optimized geopolymers. Case studies from onshore to ultra-deepwater environments demonstrate how improved planning, digital tools, and advanced materials enhance reliability and efficiency. The session provides actionable insights for operators and service providers working to deliver safe, sustainable, and economically viable decommissioning projects.
