Summary
BSEE investigates an estimated three-barrel oil discharge through Thunder Horse’s produced-water system on 13 July 2020. The report links water-quality problems to inadequate flushing of subsea well workover fluids, discusses possible emulsion and foaming, examines delayed pollution notifications, and records corrective communication training and recommendations for agency coordination.
