o, has anyone thought to say to BP, "You guys stand down and we're going to bring Shell, Chevron, Valero and the other guys in here to work on this - and you get to pay them"?
Accordingly to published reports, Exxon, Shell, et al. have engineers in BP's war room working on this pretty much 24/7. The entire industry realizes this is an industry problem. I don't think this is a lack of engineering issue.

Sorry if this has already been discussed, but 75 pages...wow.
Is it plausible that BP did not try a "junk shot" because of the readings obtained during the "kill shot"
IOW, if they clog up the BOP to stop the flow, is there enough pressure to blow off the whole BOP stack? I understand that it would be better to seal off the pressure below the sea floor with cement, but why did they abandon the junk shot?

My guess is that they tried the top kill first because it did not foreclose the junk shot. Then they tried the junk shot because it did not foreclose later options. Now they are trying the LMRP cap, which will foreclose going back and trying top kills or junk shots.
The NYT reported an anonymous "technician" who said the top kill/junk shot failed because of a problem with the "internal geometry" of what is left of the BOP stack. I've already posted what I think that means. In short, there are probably flow paths in the stack that cannot be clogged by junk. But it is really just a guess now.

Not if they can get (could have gotten) enough kill mud in. Then good old Isaac Newton and the law of gravity will take over, and there will be (would have been) little or no pressure on the stack.

Post away, bro. No problem.

16 shots of junk were made.

You got any thoughts on why they did not clog up something?

check a page or two back. I am admittedly part of the peanut gallery. I have thoughts on things but am sensible enough to know that if I thought of it, then it's highly probable that someone in a position of authority has already thought of it and determined why that won't work (i.e. inserting an inflatable into the pipe and then inflating it under enormous pressure).
Hearing that Shell,exxon, etc are also involved is new info to me. That is both encouraging and disheartening at the same time. I'm glad to know all of the industry's minds are tackling this together. I am discouraged that they screwed this up so severly that nothing will work until late August. I vacation in the florida panhandle. I have family that owns restaurants in Kenner that rely on the fishermen down there to get them their product. I have tons of friends directly and indirectly impacted by BP's negligence. Like all on here, I am just concerned with getting the leak plugged and putting 100% of the resources into mitigating the damage and cleaning up as thoroughly and quickly as possible.
You and a few others on here have provided invaluable information as to the technical stuff going on out there, and it is much appreciated. I hope you will keep it coming. I also hope you understand that many of us can't divorce our curiosity about what comes next from our frustration with what appears to be a circus run by clowns. That frustration often unintentionally influences the way we ask questions or answer them.
I just want to open the paper/log on here/turn on the news....and find out that something - ANYTHING - they tried is actually working.

Why cant they drill 1000 feet below the broken BOP and explode a "bomb" that would obliderate the well hole and let mother nature seal the leak ?

Any idea what they are doing now in the ROV shot?

I asked almost the same question a couple of days ago and I was told that the risk of "cratering" the thing and unleashing all the oil at once into the gulf was apparently a possibility.

From what I see, if you use gunk or junk which (guessing here) has less weight/gal. than mud and because of the upward pressure will flow upstream, as you continue the gunk/junk you could slow or stop the oil from leaking, but then all that pressure is at the wellhead, not down the wellbore where the casing has structure behind it to keep it from fracturing.
If they cut off that riser to install the LMRP, the riser crimp obstruction will be gone and things could get worse.
Also, since they repaired the pods, why can't they signal the rams to work? Which again would create an enormous amount of pressure at the BOP/wellhead which if it blew...I don't even want to think about.

That is my view. You would make a bigger hole than you have now.
Also, I personally doubt that you could get an explosive very deep down in that well.
No matter what, the BOP is holding back some of the flow, and you do not want it to let go. That is one of the reasons they have been proceeding carefully.

That is why they tried top kill/junk shot first.

It is not a signal issue. They physically pulled the switch on the rams at the subsea. The rams did not seal. Or at least the shear rams did not.
Rant begins. Beware. It is not directed at you. I am glad you asked the question, nuwaydawg.
This is one of the media myths that has become urban legend. "If they had just spent 500K on an acoustic switch, none of this would ever have happened." Uh, wrong. They used the method planned for, which was to send an ROV down and pull the switch at the BOP if all else failed. That happened just a few days in. It did not work. If physically pulling the switch at the BOPs would not do it, then a sound signal from a boat would not do it.
Rant ends. For now.

Missed this part of your question. I have seen on this board that there are major hydraulic problems. Don't know that. I do remember reading that they hooked up a hydraulic hose from surface early on and still could not get the shears to close. Don't know why.
I don't think they have "repaired" the BOPs. I think you would have to get the housing off to repair them. That ain't going to happen til they get the stack off of the well.

I didn't realize this. I thought all they were pumping down the choke and kill lines was mud.
Clogging up a 16" hole under pressure through a 3" pipe is a challenge. I've heard all the golf ball, tire and rope solutions, but you're still talking about delivery of these through a 3" pipe.
I'm going out on a limb here. Crazy idea time.
Puree some hair/wool. Matted, I have no idea how much pressure it could overcome. It has fricked up my bathtub drain on numerous occasions.
It's at least as credible as golf balls.

There is no repairing the stack I am sure it is washed out now and will only get worse the longer this flows.

To all posters.
Thank you.
This board has done wonders for my blood pressure. Really.
I want to commend everyone, if I can do so without seeming preachy, for good questions and excellent follow up. There are some people here who really know there sh . . ., er, stuff. Everybody here, hopefully me included, is trying to listen to everyone else. That is going to be really important as we go forward in Louisiana from this.
Sermon ends. I gotta get to work.

We can't "brush" that idea aside. We need to "comb" over it. It could offer a really good "bang" for the buck. You might be a "part" of the solution.
Dang. Come to think of it, that sounds like a pretty good idea. Heck, it sure clogs up my drains at home!

That or just send me on one of those 36 hour Taco Bell/tequila benders I used to go on in college, then hook me up to that thing.
