Dont know if this was brought up yet but could they go down and thread the outside of the riser pipe then screw on a collar with a flange valve on top and shut it off. I doubt they make threaders that big.

man, whenever I click on the underwater cameras I'm hoping for some kind of reduction in the flow. Perhaps there is, but if so, it isn't much. Depressing........

a few questions:
Why are they venting oil for so long before they start closing the vents? I would think that it would suffice to vent until the cavity of the top hat is filled with oil and no water and then slowly close until you have as little oil as possible venting ou in order to assure no seawater is in the cavity
Several pages back you said you just cant crimp off the riser as pressure would build until the whole thing exploded. The pressure would build until it equaled the reservoir pressure, yes?
If the lmrp cant handle reservoir pressure how the heck do they control a normal "good" well????
My current idea is to attach a riser to the the big containment dome and pump diesel fuel down from topside until the whole darn thing is filled with fuel and no water, place it over the lmrp and have a pump inside the riser to pump the oil to the surface, even a small( 10hp would help) all the while letting some oil leak out the bottom of the dome to assure that no seawater gets into the dome.

Flow looks like crap again. It was temp. much less than it is now.
Yes I have not been able to understand why the cant make a big dome with a bunch of connections and hook up as many pumps as needed 2 pump ot almost all the flow like u said. Seems so simple.
Can the really not suck hard enough to pull up 12k barrels of oil through the existing riser???

there's more than 12k barrels coming out.. and that's not including the gas that's coming with it

Just seems that they are content with dragging things out until the relief wells are complete and just attempting something until then just to show that they are attempting something.
My sentiments exactly

Last official estimate I saw was 12,000 - 19,000 BOPD. That's probably pretty reasonable for an estimate instead of the original 5,000 or the researchers 100,000.

BP has collected 6,000 barrels of oil in the first 24 hours of pumping it from a ruptured well up to a drill ship, Coast Guard Adm. Thad Allen, the federal government's response manager, said Saturday.
and its still gushing bad

It looks better to me on one side. Perhaps that's an indication that they've closed some of the valves.
My understanding of why the large cofferdam didn't work is that the large volume allowed too much hydrate to form. The smaller "top hat" displaces seawater and prevents that from happening. In theory.
Then again the difference between theory and practice is that in theory there is no difference. In practice there is.

Assuming for the sake of discussion that the 19K barrels per day is reasonably accurate. That means that they captured roughly 33% in the 24 hour period. Based on the visuals it sure doesn't look like the output flow has been reduced by a third.

If they are obtaining 6,000 bbd then that is indeed encouraging. They are planning on using the choke and kill lines they used during the top kill operation to also siphon off at the BOP. Hopefully that operation will yield another 2,000 bbd or more.
Everyone keeps talking about pumping. My background is in the chemical industry and I've never seen a two phase flow centrifugal pump because of the cavitation it would create. I don't have any experience in the oil field though.
The process they would need to set up next is a vacuum hose type device which siphons the oil / gas / water to a separator where the natural gas is then flared off and the remaining oil / water is then separated and the sea water returned to the gulf. Problem is I doubt such a vessel with these process capabilities exists and you still have the hydrate formation problem to contend with.

What do you propose that they do? Hire aquaman? Dude, what they have done has been pretty amazing. I am going to take a WAG that you don't have a technical background. I don't mean that to put you down. I mean that to say that those who know think this is pretty impressive.
If you do have a technical background, put it out there. What would you do?

Roger that on the problem of pumping a two phase mix with a centrigal.
Ok put an old prop pump in the line, not real efficient but they do pump

If you "suck it," you pull seawater in and freeze it up. And that would suck.
Right now it is producing under its own pressure. If the pressure drops so much that they had to "suck it," it would not flow to begin with. It would just remain static.

Don't remember that. Do rememeber that the guvmint pulled the plug on top kill.

Judge,
That was originally my quote. It came from the frustration that they abandoned the original LMRP plan with the elastomer seal to recover most of the oil / gas.
Yes what they have accomplished has been pretty amazing.
What they would need to do is go back and get a clean cut with the diamond wire saw and then use the original LMRP plan to create a good seal and recover most of the oil.
The frustration came from that they scraped that plan because it seemed like the Coast Guard or some other authority ordered BP to use the Top Hat plan instead of going back to the wire cutter.
Was this decision due to Friday stock close coming up or Obama's visit? Who knows for sure but I think a lot of folks would like to see them go back to the original LMRP plan to get a tighter seal and recover more of the oil.

I see that in one view the level on the BOP is closer to level than it has been. Are they attempting to level it off or is just free floating and happens to be more level now? Or are they just looking at the valve next to the level thinking about opening it?

Also, does anyone have any idea whats going on in poseidon ROV I?

Quick question (which might already have been answered but I dont see it) -
during the last "experiment" that failed they managed to pump in the "mud" and stabilize the oil to where there was mostly mud coming out and just a little oil - then they found they could not control it well enough to "kill" it. I believe this happened below where they are working now.
Why not continue that process, knowing they wont be able to "kill" it but at least minimizing the oil coming out? Would that interfere with what they are currently doing?
