Summary
BSEE investigates a fatal casing pressure test on Eugene Island Block 158’s platform. Gas supplied from an adjacent well without pressure regulation or a pressure safety valve overpressurised the casing. The report examines incomplete job safety analysis, absent management of change and possible confusion between gauge display units.
