i'll tell you how i would kill it. i'd take the riser off of the lmrp, exposing a 19" hole.


May be in the near future, IMHO.

Suttles mentioned the BOP on top of BOP scenario at yesterday's 4:30 presser. BOP/BOP w/ LMRP attached will allow the flow to be directed up to the Enterprise for seperation. You can then slowly choke it down (hoping to not cause a SS blowout).

Is the path from the top of the LMRP to the bottom of the BOP into the wellhead a straight line down? I would assume so but not sure. Would the upward pressure from the oil/gas flow prevent drill pipe from entering the hole?


straight line.

they do not want to mess with the BOP bc it is restricting some of the flow and for potential legal reasons. It is going to be a big piece of evidence in the investigations.


F**K protecting legal evidence. Get the f'ing thing fixed!

NOT A CONSIDERATION........they have already taken and reconfigured the pods.....

The existing drill pipe (that may have prevented the shear rams) may prevent you from entering hole.

did they ever confirm that they do, in fact, have drill pipe locked in the rams?

I believe the plan for next week may be to take the riser off and stack another valve/bop on top. Taking the riser off will allow the well to flow ALOT more. Should something happen and BP can't kill the well, BP is toast.

Not to my knowledge, but it is still a possibility. Many things can happen when the riser is detached from the existing BOP, most of them bad........but it is getting down to that stage, IMHO.

i know BP doesn't want to remove the riser because of the fear that it may undo the restrictions on the flow caused by the kink.

however, it seems like stopping the leak is going to be pretty impossible with the current condition of the well, but taking the riser off the top gives them way more options. i gotta believe 1 or 2 days of unrestricted flow is gonna be better than not being able to shut down the well until August.

I believe it was Fox news early show the other day said BP profits $93 million a day and this has only costed them about half a months profits so far...

including being able to sit the top hat on the stack as opposed to sitting it on the stack and the riser laying on the ocean floor.

Not positive but I think there is still a substantial amount of drilling pipe in the well. If this is so they would have to fish it out once they remove the bop. But if it was all tripped out then it depends on if the shear rams are open enough, and if not whether they can open back.

is the stuff coming outta the pipe at this point in the topkill process supposed to be so black, black, black?

Pieces of the Hydril and elastomar have come up in the top kill effort. Oil has been flowing through it uncontrolled for 37 days. I don't think evidentiary value of much of a concern here.

Beside, Cameron only has 500 million in insurance.

1 to 2 days of unrestricted flow isn't the issue, it's if they can't kill the well and have to wait until the relief wells have done their thing.

i'd enter that hole with a bha (drill pipe with a tool on the bottom) and one of two things:

1- set a storm packer
2- start pumping mud at the same depth that they want to enter with relief wells


Wouldn't that be like pushing a pinwheel into a firehose going full blast? Don't know, but just sayin.

Tried several times early on to close the shear rams....sent several junk shots and tons of MUD after that....chances of opening shear rams fully approaches zero, IMHO.

I think they like the thought of applying a new fully tested BOP stack but are afrais to remove kink. Top hat is still an option. Maybe even try Top Hat in conjunction with a new larger Riser Insertion Tool (RIT) that is currently parked on bottom before removing the riser.

no. you see, this pinwheel would weigh over 500,000 pds. (if you use a hell of a lot of collars for the bha).

I said it was possible evidence bc from what ive heard they are really keying in on the changes that were made to the BOP. Also Cameron is in the clear, they notified BP and Transocean that particular BOP had problems and needed to be taken out of service.
