Deepwater Horizon - Transocean Oil Rig Fire

[QUOTE=alcor;36177]What went wrong?
Cement job.
Positive and negative test data misinterpreted and misunderstood.
No CBL.
No second barrier (plug).
Displacement to BOP with SW with a DP string at 8300 ft (no-one able to recognise pressure on standpipe indicated gas in the well)
No Volume control.
No pressure control.

All the screw-ups that the cement job and misinterpretation of data related to the negative/positive tests still required the Drill crew to be on guard.

When I go to bed on the Rig I’m hoping that the next crew who relieve me are competent at reading the signs in the well. It has been unacceptable to mention these points up to now.[/QUOTE]
Add to this an F?><ed up casing design, totally screwed up cement job that the client ordered, & a screwy set of instructions for the day’s work from the Houston office & you’re getting warmer.
