Summary
An MMS alert describes natural gas escaping through a corroded ring gasket during well scale-removal work. An inoperable subsurface safety valve prevented containment, and the platform was evacuated without injury. Acid treatment possibly accelerated gasket failure. Recommendations address acid-operation policies, emergency plans and gasket history or condition.
