Summary
Investigates natural-gas release during wireline scale removal and acid treatment at South Pelto Well No. 10. The panel identified ring-gasket corrosion, likely acceleration by acid treatment and an inoperable subsurface safety valve prolonging the event. It examines wellhead testing, integrity inspections and platform evacuation, recommending reviews of acid-operation policies and emergency plans.
