Accident Investigation Summary
Summary Nr: 102574.015Event: 01/22/2018Three Employees Are Killed In Drilling Rig Explosion
At 8:37 a.m. on January 22, 2018, five employees were working on an oil rig, tripping out the wellbore to change a bit. During work, the gas surfaced as the pipe/bit was removed from the well, causing the well to burp. Once the initial burp subsided, another burp occurred and gas fumes found an ignition source, causing a series of explosions on and around the rig. Five employees were in the doghouse, unable to escape and were over come by smoke and excessive heat. Three employees were killed.
