Summary
Two Gulf of Mexico coiled-tubing operations suffered tubing separation after encountering unknown obstructions. Failed well-control interventions and absent back-pressure valves led to uncontrolled flow and platform evacuation. The alert recommends hazard analysis, force limits, backflow protection, supervision, communication, equipment-specific procedures, training and weekly well-control drills.
