Summary
BSEE investigates a well-control and pollution event at West Delta 80 D during coiled tubing work. The report examines tubing-to-casing communication, probable corrosion-related alignment pin plug failure, delayed remediation and reporting, and inadequate fluid-handling capacity. An estimated 107 gallons of hydrocarbons spilled; all 19 personnel evacuated without injury.
