Summary
BSEE investigates a casing leak at South Pass 28 13(V) that released oil and gas into Gulf of Mexico waters. The report traces unsuccessful well-killing attempts, bridge-plug isolation and welded repair. It identifies inadequate preventive maintenance, corrosion and erosion as probable causes, alongside rough seas and shallow water as contributing conditions.
