Summary
Investigation of a gas blowout at Main Pass Block 91 Platform A, followed by platform subsidence. The report examines sustained casing pressure, poor cement quality, diagnostic testing and procedural communication failures. It describes unsuccessful kill attempts and relief-well abandonment, while leaving the precise casing-failure mechanism unresolved and recommending abandonment of remaining wells.
