[QUOTE=alcor;38408]Incorrect. Our 1/4 Bbl of gas has to be allowed to expand. We monitor the SICP on the Choke guage and bleed off as required at surface to ensure the WH integrity is not compromised. Our weak zone may help if the volumes are small, in that the bubble will expand on its own. The casing will not be ejected from the well. The Rams are closed, and pressure above and below the Seal Assy/Hanger are the same if a leak exists.[/QUOTE]
Keep trying.
[QUOTE=company man 1;38409]I won’t argue this point with you again since you haven’t even attempted to tell me I’m wrong. You, as well as Pumping Jack as well as Alf as well as Kasol as well as Kasol and any others who have first hand experience on a rig all know that the way I explained it is the way it was going to happen. There was no choice. This well was either going to blow inside or outside of the 16" casing when the gas started migrating. The underbalance didn’t cause the migration. It just revealed it. The cause wasn’t well control failure during displacement, although I certainly agree with you that it didn’t help. The cause was putting nitrous oxide on 1500 horse power car without any breaks. Those choices were made days before this blowout occured.[/QUOTE]
We’ll have to see what the volumes were during the cement job to verify your migration statement. And, what the well volumes were for the 18 hours after the cement job. Did TO report any volume increase? No. Then we have to accept that no gas was in the well until displacement of SW took place. Show me evidence to back up your statement, that migration was already occurring. If you have it and TO aren’t aware of it then TO are in bigger trouble than originally suspected. I don’t believe there was any migration. I believe, movement of hydrocarbons from the Reservoir into the well occurred when the well went underbalance, when the SW displaced the 14 ppg mud.

If the bubble is left to migrate and the volumes back as it migrates are ignored there’s a good chance that the casing Hanger would have blown out.
Now, you answer my question:
Who is responsible for volumes and pressure observation on the rig?
I won’t tell you you’re wrong because I don’t want this to flare up. I want to explore what’s happened. I want to keep it clean. If I’m wrong then tell me.

The well was sealed once they bumped the plug & released from the hanger. There was no way to detect migration until they negative tested. The migration was obviously there. That was a clear indicator the cement hadn’t held & that gas was swapping out with the mud. At that point its game over because you don’t have isolation between the 9 7/8" & the 16". Since you don’t have isolation & the 16" is booby trapped with rupture discs that are rigged soewhere below rated burt pressure, once they go, then its onto the 18" & the uncemented section at 3800’ below the mud line. Once pressure gets high enough it blows out around the whole well head & comes in like the blowout video Kasol showed only a whole lot harder than that. Do you deny this could happen?

How many times do you need to me to tell you you were right about the mistakes of the crew & the company man? Now you may at least admit that I can be right about the other outcomes no matter what they did. BTW, you might want to hit your little knees tonight & pray that some bastard/bastards on a beach don’t do the same thing to you without you even knowing it.

How much gas was in the Annulus?

One thing you conveniently forget, Alcor, was that the pitbull Vidrine and his Houston handlers had already browbeaten some of the crew into submission. In my humble opinion. BP was dictitorial on this rig, and nobody dared to cross him/them. So interpretations and objections and reconsiderations and concerns for safe operations were completely subsumed to The BP Wrecking Crew. That’s why I doubt you are a real floor hand. You obviously know the textbook stuff about well control, but you give absolutely no considerations to REAL WORLD working environments. You’re a suit, Dude, and the quicker you admit it, the better your words will make sense. But for now, anybody who has worked for tyrants knows how far they can push it before they are put on the next boat back to the beach.
[QUOTE=alcor;38419]How much gas was in the Annulus?[/QUOTE]
Enough to blow the rig to kingdom come. The better question is where did it come from & why was it allowed to leave there?

I’ve woken up to the rig shaking! There’s danger in this line of work. Fortunately, I get a handover with both drillers on the rig and we debate what can go wrong. I would never suggest we have operated 100% correctly and on occasion have lined up Choke Manifold incorrectly. We now have new procedures in place which means that if you open a valve anywhere on the Choke or standpipe manifolds we confirm the line-up with pressure of 150 psi. I’m not complacent and realise things can get hairy. That’s where we need all parties on the rig working together. But, there are one or two drillers you have to keep an eye on.

And your evidence?
Remember, I’m talking about while we still had 14 ppg in the well. You said it was migrating.

Who is in charge of the vessel? Is it Vidrine or the OIM?

Why are you so dogmatic that you don’t get my point? I understand what your procedures are & I will guess that you do quite a bit of completion work. I quite frankly don’t believe these guys had enough experience in realizing once this hole was cased that it could still bite thme in the ass. It sounds as if this rig was strictly for drilling & may have been assigned to just drilling exploratory wells.
The fact still remains that when they changed the casing design & continued to be so wreckless with the cement that they caused a blowout situation below the rams. That is undeniable. Now for at least the third time I have admitted the crew screwed up. You, for the betterment of your own future safety as well as everyoe else’s need to come clean and admit that it didn’t matter what happend at the stack if the bottom was rigged to explode it was going to explode.

Pinpoint for me when it entered the well.
Are you speculating or drawing on facts?
[QUOTE=New Orleans Lady;38424]CM1 ,is this it?http://www.youtube.com/watch?v=sYTO_0_0ReQ[/QUOTE]
Its another one where the gas came up around the rig & blew for a while then they were able to get everyone off.

Obviously at some point before the first test. Don’t do that. You know as well as I do the well was static until they tested the annulus.
Edit: It was static at the surface anyway.

It would not explode if small volumes entered the well. That’s why TO are responsible to ensure volumes and pressure are controlled. That’s why when they started cementing if anything was wrong with volumes (gain), they should have shut in then. If a gain was seen.
Bottom line: Gain? Shut it in!

It was static with 14 PPG mud. Not with SW.
Replicate what you intend to do. If the well is to be displaced you have to replicate this. How do you do it?
Refer to my previous posting on Negative testing.

The gain was the indicator. Once they shut in the gas is still swapping out with the mud. You know that’s the case that’s why they couldn’t get a top kill. You know good & well that this casing should have been a tie back & you’re just being pigheaded about it.
