Summary
An offshore development well suffered a gas blowout during attempts to kill a deep saltwater flow. Gas jetting formed a seabed crater, undermining the platform legs; personnel evacuated safely before it toppled. The alert reviews drilling warning signs and planned casing-integrity checks, cement evaluation, well-control training and reassessment following operational deviations.
