@amazeifystore: The Deepwater Horizon disaster was not caused by one bad valve. ⚠️ On April 20, 2010, failed cement isolation, a misinterpreted negative-pressure test, and reduced well pressure allowed gas to surge onto the rig. The explosion killed 11 people. The lesson is critical: well control depends on every barrier working, being tested, and being correctly understood.
