This panel session explores the complexities of HPHT and deepwater well delivery, where technical uncertainty, operational risk, and high capital exposure intersect. As the industry moves into increasingly challenging subsurface and operating environments, effective decision‑making requires a careful balance between technology deployment, risk management, and value realisation. Key challenges include subsurface uncertainty, geomechanics, drilling risk, and development cost.

Drawing on experience and lessons learned, the discussion will examine how operators and regulators navigate narrow drilling margins and manage uncertainty, with a focus on delivering wells safely, reliably, and commercially while maintaining regulatory confidence.

Panel discussion will include:

• Managing subsurface uncertainty and geomechanical risk in HPHT and deepwater wells
• Early integration of reservoir, geomechanics, and development planning to protect value
• Decision‑making frameworks under narrow margins and high uncertainty
• Technology readiness, qualification, and adoption for HPHT and deepwater applications
• Operational risk containment and assurance during well planning and execution
• Balancing safety, regulatory requirements, and commercial outcomes
• Emerging technologies and evolving practices for HPHT and deepwater developments
