One of the Last Off Alive - An Interview Worth Watching

| 10 Comments
As we gather more information about the blowout of BP's Mississippi Canyon 252 well, conflicting accounts are emerging about the cause, who's to blame, and exactly what happened.  The picture being painted of the final moments before the loss of the Deepwater Horizon became clearer last night as Mike Williams, an electronics technician on the rig told his story on 60 Minutes.  Here it is, in 2 parts:

I can’t help but wonder if there was an MMS waiver issued for operating with a damaged control pod. It seems pretty farfetched that Transocean would keep something like that a secret given the potential consequences.

Is the drilling report on-line somewhere?

Old Man,

There's nothing on the drilling report that shows it was perforated. The ran casing, circulated, cemented, set the packoff and set the bottom plug. They came out of the hole, picked up about 20 something joints of tubing as a stinger on the drillpipe to 8,367' to set the top plug. After that, the report goes blank.

Yes, when I started on rigs we called it the Hydril because Hydril made most of the annulars in use. The annular on this BOP, however, was made by Cameron. I'm not sure about this whole getting rubber back. As you say, annular rubbers are designed to move drill pipe through, so I'm not sure what could cause that kind of damage.

You guys are all looking at this from a technical point of view. Fine.

What I hear from this interview is not complicated.

BP was past schedule, and over budget on this well.

It was a "finish it fast", (not necessarily safe situation.)

The guy from BP, and the guy from TransOcean got in a pissing match on the best method to be used on how to cap this well.

The guy from BP (the lease holder) prevailed....

Given that news reports today are saying that BP accounts for 97% of all the safety violations in the oil and gas industry... the outcome was not that big a surprise.

Neither is the fact that they are trying to lay the blame on others.

We are all better for the fact that this man was spared, and lived to tell his tale.

Bob, do you know for a fact that the well was not perforated, or is only standard procedure for the completion unit to do the perforating?

In my day the annular was called the "hydril" and I seem to remember it was common practice to pull drill pipe thru it when taking a kick. So I am not excited about the annular. Maybe my memory is gone with my youth.

Does the damage to the annular explain the "anomalous" pressure tests?

The casing was not perforated, nor do I think the cement plug(s) failed. The gas came up the outside of the casing to the packoff. The packoff failed, or the casing collapsed, allowing gas into the riser at casing head.

I believe the pressure was on the outside of the casing, under the casing head packoff. Even if they had set the cement plug inside the casing, I don't believe that it would have prevented a blowout when they displaced the riser to to pull off the riser and BOP.

listened to the 60 min thing again. It sounds like the well was perforated and the casing cement job was not bad. And, maybe the two temporary cement plugs did not hold after the mud was circulated out prior to setting the third plug. Comments?

I've got a question for Eljefebob, based on the 60 Minutes report of the annular seal being damaged. If the crew had left the mud in place and put in the top concrete plug would the production rig have had a blow out when they redrilled the well?
