Summary
Investigation of a workover blowout at Eugene Island Block 28, offshore Louisiana. Production tubing parted during pulling, allowing well pressure to eject tubing before preventers contained the annulus. Metallurgical examination identified fatigue cracking and flow-cut wall thinning. The report reviews barrier tests, work procedures and subsequent snubbing operations to kill the well.
