Deepwater Horizon - Transocean Oil Rig Fire

[QUOTE=Alf;39362]It should be an interesting couple of days…

Once they remove the flex joint they may be able to get a better idea where the flow is coming from ie either from the annulus, the drillpipe or both.

[/QUOTE]

FYI, the flexjoint is staying, only the remains of the sheared top flange that is mated to the top of the flexjoint is being removed -

I can imagine there will be a lot of people sweating profusely on what those two bits of sheared DP that are stuck in there are going to do when that top flange is split.

[QUOTE=New Orleans Lady;39323]Alf , interesting to note, that ya ll came to the same conclusion, as far as gas being mixed with the cement< pardon my verbage>. So , my question is,did the times get this info from this thread???[/QUOTE]

There is a lot of wrong/misleading info and statements in the article. My guess is that it is a regular journalist reporting and no experienced input coming from else where.

…“swallowing expensive drilling fluid and burping out dangerous gas…”??

Sorry, you’re right, my bad. Thanks.

Boy am I confused now! The BP plan clearly states they intend to immediately shut in the well after the addition of the short stack BOP above the flex joint. Either the reservoir pressure has dropped sufficiently to not breach casing, or they are nuts. What have we missed on this thread? I don’t think any of us were comfortable with shutting in this well with no hydrostatic help from mud given the casing/liner design.

  1. At present this plan moves to shut in the well directly following the installation of the capping stack and the cessation of collection from the Q4000. Attachment A illustrates the range of possible timings for shutting in the well. Details for the shut-in procedure are being finalized in a meeting today, July 9th 2010, with the DOE, DOI, Federal Scientific Technical team and Secretary Chu who will be in attendance. The detailed procedures will be finalized and submitted to Unified Area Command for approval following this meeting.

I saw that too. The Helix Producer is supposed to start up today/tomorrow. Maybe they’re thinking it will be taking enough in to help limit the pressure. Why are they stopping the Q4000?

Scary dare devil stunt perhaps ? Would this not cause surface broaching or underground blowout even if the well is only flowing through casing vs casing annulus, reducing relief well kill chances of success ??? This well had experienced 4 well control problems prior to blowing out and took massive losses below the reservoir. Perhaps Dudley has no technical background let alone knowledge of well control basics or perhaps he knows something the rest of us don’t ? Or perhaps when they say shut-in they actually mean just fixing this new containment cap ?

They are still quoting around 9000psi whd pressure, similar to when they tried the top kill!
They say they hope to see 9000psi when they shut it in with this mini BOP, which to me means they will close in with this new mini BOP.
They know there is damage to the well/annulus as they stated so after the top kill attempt.

This is an absolute “must” read. I would venture to say,that many of you guys, get credit for this valuable information. And, if no one else does, I certainley do. “thank-you!” http://www.drillscience.com/bp/#bn-forum-1-1-258780943/7897

the “root cause analysis” is esp interesting…sounds like the author, was a frequent flyer here, hhhmmm anyone dare to guess who?

"Tell him the 4.1 bbls expands to 70 feet 8.4 bbls and 800 psi under
the casing hanger and that was enough to breakdown the weak zone and
push mud out of annulus.

It wasn’t arbitrarily applied like Obama’s moratorium."

TV, there is no use in trying to reason with this BP hired gun. He is only out to cover BP’s ass because he knows they are guilty of premeditated negligence leading to the deaths of eleven men & causing the greatest environmental catastrophe in the history of the world. He let the cat out of the bag weeks ago when he was arguing against air that BP made the change of well plan from exploratory to production during the last days of drillng the well, when it is evident by their running of the rupure discs in the 16" that they had planned on producing this well before it was ever drilled. This meant that they were responsible to put the best available system in place to mitigate any possible dangers. Instead they made the conscious decision probably months before to run the cheapest well design possible & balme the government or their vendors if anything went wrong. They didn’t actually THINK anything would happen, but were already prepared with fingernails sharpened before the occurance to place blame on anything or anyone else for the damage caused by their premedtated death & destruction. How else do you think he turns so quickly from the MMS to TO to the company man to the BOPs every time the natural sequence comes back full circle to BP’s negligent planning & design as the root cause of this disaster. Remember the blame the cowboy mentality of US culture. This was a smoke screen when he as BP insider knew what the management of his company had planned to do & how they planned to blame others that they either cohersed, bribed, extorted, or plain ignored in their headlong push to make this disaster occur.

What an extraordinary statement to make. Those of us who believe in the offshore oil industry’s survival want to know the truth of the events the days prior to the disaster struck. We can all speculate about the failures. One fact is this: BP, are doing every possible thing to right the wrong. I guarantee all of you that there is much more to be revealed. Revealing some of that information may compromise the efforts to drill the relief well due to TO’s implication.
Those who work in the industry understand ‘last line of defence’, and who has the responsibility to take action. Those who want to simply fill their car without any understanding and appreciation of the dangers in the oil industry should hold their comments for other media outlets. Wild statements without any basis for fact are the media’s attempt to understand an industry which is so dynamic every well drilled is different. I hope this discussion thread is designed for those with intimate knowledge of the industry, and particularly, operations from Semi-Submersible vessels. This is what the investigation is all about.

As for the rupture disks, I believe every Oil Operator that I know of would like to convert an exploration well to a Production well. Again, it’s extraordinary, that anyone thinks this is not possible. Do not mislead people with inaccuracies.

Welcome back Alcor. I was beginning to wonder if Corexit induced cancer in you yet. But then agian I knew that fetish you have for defending crooks would compel you to crawl out of that hole you and BP have dug for yourselves.

Do you think shutting in the well with the new cap is a good idea ? or would it risk surface broaching or underground blowout ? Your technical responses are always most entertaining. Thanks.

Now, Blisters, ,come back here,not polite, to eat,and run!

[QUOTE=Alf;39379]

I thought about this all day as I worked to get the wifey’s kitchen back functional. 3 weeks without a sink or cooktop as the ol’ guy is slower at construction than he used to be… There has to be a lot missing in “translation here”, I think. From watching an interview of John Wright, it is clear to me that he is a very talented, calm and measured man. He is the kind of platoon leader I would still gear up for if he called me. Every assessment of his ability that I have found has been positive to the extreme. I do not believe he would allow BP to do something stupid and still remain on DDIII. I think he is the kind of guy that is going to manage this intercept well and if BP is determined to implement something that will compromise his crew’s safety or chance of success, I just think he will calmly assemble his team and chopper off.

That said, I could see this short stack BOP helping John Wright with the kill by deadheading the WW after he gets some mud column in and while he fine tunes mud densities. Think it would also help tremendously during the cementing phase. From the 16 inch casing burst pressures that I have seen, the dead head pressure would have to be down to a little over 6,000 psi to make the risk of outright deadheading with no mud in the column statistically responsible, and that is with undamaged casing/liners.

On a side note, it just doesn’t seem ‘right’ to have Alcor back and not CM1… The ‘balance’ just doesn’t seem in harmony with the universe, sort of like the sun is going to explode… :smiley: Until the posse finds and frees the good CompanyMan1, perhaps Blisters could temporarily fill the role?

[B]THANKS FOR EMBELLISHING MY COMMENTS AND REDUCING EVERYTHING TO YOUR OWN ANXIETIES.[/B]
[B]REGARDING SHUTTING IN, I HAVE NO IDEA WHAT THE DYNAMIC PRESSURE IS, BUT I WOULD ASSUME WELLHEAD PRESSURE WILL REACH ANYWHERE BETWEEN 5000 AND 8000 PSI, WHICH WILL DEPEND ON HOW MUCH GAS IS FLOWING COMPARED TO OIL. THE MORE OIL, THE LESS THE PRESSURE, DUE TO 0.85 SG SPECIFIC GRAVITY COMPARED WITH GAS 0.19 SG.[/B]

[B]WHY WOULD THEY WANT TO SHUT IN? I IMAGINE IT’S BECAUSE THEY NEED TO PERFORM THE RELIEF OPERATION WITH MUD TO SURFACE. OR, THERE MAY BE A MEANS OF PRODUCING TO A NEARBY PLATFORM WHICH WILL BE REQUIRED IF A HURRICANE FORMS AND THE VESSEL HAD TO UNLATCH. I’M GUESSING. I’M BACK OFFSHORE, AND HAVEN’T HAD TIME TO KEEP TRACK OF EVENTS. ONE THING I HAVE HEARD BEING DISCUSSED BY COLLEAGUES IS THAT IT MAY TAKE 2-3 WEEKS TO KILL. I MUST ADMIT THAT I THOUGHT THE KILL WOULD TAKE LESS TIME THAN THIS. I SUPPOSE THEY HAVE TO BE CAREFUL THEY DON’T INDUCE AN UNDERGROUND BLOWOUT OR CHANNELING THROUGH ANOTHER AVENUE.[/B]

[B]I STILL DON’T KNOW WHAT TO THINK. WHY DO WE HAVE 2 JOINTS OF PIPE? DID PIPE FALL DOWN THE HOLE AFTER THE EXPLOSION? I SUPPOSE ALL WILL BE REVEALED IN TIME.[/B]
[B]I STICK TO MY GUNS: VIDRINE, CAUSED THIS BLOWOUT, AND I AGREE WITH YOU, BECAUSE HE FAILED TO CIRCULATE OUT ANY POTENTIAL GAS. BP, INSTRUCTED HIM TO CIRCULATE. HE MADE A DECISION TO IGNORE THIS AND NO-ONE ON THE RIG WAS STRONG ENOUGH TO TAKE HIM ON. TO ARE IN CHARGE OF THE VESSEL AND ALL SOULS ONBOARD. THEY MUST KNOW THE CONSEQUENCES OF EVERY ACTION TAKEN. THEY DIDN’T. [/B]
[B]AND, I’M PREPARED TO WAIT AND SEE WHAT BP OFFERS AS A DEFENCE. I WON’T DEFEND ANY PARTY UNTIL I SEE ALL THE EVIDENCE. AT THIS POINT IT APPEARS THAT BOTH BP AND TO HAVE A GREAT DEAL OF EXPLAINING TO DO. AND MMS, HAS FAILED IN ITS OBLIGATIONS TO POLICE THE INDUSTRY. THESE ARE ALL UNDISPUTED FACTS.[/B]

[B]ONE MORE POINT: I DON’T SEE HOW BP’S PARTNERS CAN CLAIM THEY AREN’T INVOLVED IN THE ECONOMIC REPERCUSSIONS, THAT THERE INVESTMENT ONLY INVOLVED PROFIT!!! THEY INVEST, AND TAKE THE GOOD WITH THE BAD! THEY WILL PAY THEIR SHARE.

Open your eyes and you’ll understand ‘balance’. Understand the dangers which crews face on a daily basis. Operators, and Contractors, do their best to reduce the risks in the industry, but you have to realise that delivery of gas to your car comes with consequences. None of us are immune from the disasters which take place in our society. Accidents, occur every day even though we do our best to minimise risk. Our society requires oil. BP, is the leading deepwater drilling Operator in the world. That’s a fact you will find hard to believe.
BP, regret this massive failure more than you can ever comprehend. And, so does every Operator and Contractor Worldwide, as our operations are being scrutinised on an hourly basis.

Ahhh Alcor, thanks for being kind with this ol’ guy… the ol’ guy who hasn’t a clue about risk management… if you only knew…

This “incident” in the Gulf was entirely preventable:

[ul]
[li]Flawed well design by BP engineering[/li][li]Flawed execution as directed by BP mandated “shortcuts”[/li][li]Flawed on site well management by BP[/li][li]Flawed on shore well management by BP[/li][/ul]
That about covers it in my book. The rest of the details will work their way through court for the better part of a decade. Don’t worry, BP will still be there, it is “too big” to fail in today’s ever increasing socialist society. The fact that you provide 1/7th of Britain’s retirement fund income will result in the intervention of your sovereign…

Have a nice day over there, my friend. :slight_smile:
