    How much Pressure *psi* Will it Take for BP to make a Bottom Kill?

     
    How much Pressure will it Take  BP for a Bottom Kill?
    It will take over powering the pressure of 6,6000 psi, @ the Top, at least 15,000 psi at well bottom = maybe 20,000+psi
    Now try to imagine 6,600 psi. How about three oxygen or acetylene tanks, blowing there tops off at the same time. Each tank is about

    2,500 pounds per square inch each.

    The Bottom of the Well is about 15,000 psi or Six of these tanks going off at the same time and BP has to overcome that with even higher pressure.

    The flowing wellhead pressure according to BPs measurements is around 6,600psi they measured it before they tried the top kill the first time. The top hat would grenade well before they reached that pressure.

    This is comparable with the pressure in an oxygen cilinder for welding.
    If the valve of a compressed air cylinder is broken or sheared off,
    the released pressure will cause the cylinder of 190 lbs to act like a rocket, shooting away quickly.
    But at the point where the drill hit the oilwell 30,000 feet under the bottom of the sea
    then one has to add another column of 30,000 feet oil representing about 13000 psi
    totaling about 15,000 psi.

    At least this should be the pressure in the well to push the oil up just to the level of the rig.

    Compressed Gas Cylinder Storage and Handling

    Compressed gas cylinders are used in many workplaces to store gases that vary from extremely flammable (acetylene)

     

    to extremely inert (helium). Many compressed gas cylinders are stored at

    extremely high pressures (up to 2,500 pounds per square inch gauge or PSIG).

     


    You do the math

    Waterjet cleaning of steel tubes, piping and vessels is routinely conducted at pressures from 5,000 to 40,000 psi.

    Blowout (well drilling)

    SIMMONS: ...when you look at the riser [on the live BP video], you realize that you're looking at a twenty-one-and-a-half inch circumference riser, and there looks like somewhere between a six and seven inch rip on the top. So the stuff coming out -- it looks like a lot, but I actually saw a white fish go through it and come out white. So I said, this isn't the same as this brown, gooey, orange stuff that they found in the plume seven miles away. And I still believe that what happened is that the riser blew off the wellhead, and it's hooked onto the rig; so you've got a mile of oil inside that that's pretty light concentrate. So that's what they're actually trying to get out. So it's not sure that -- luckily they placed the top kill correctly. But now they have to see if it will take mud. It probably will take mud. But then they shouldn't delude themselves that they've stopped the spill; they should now go and say, 'Let's figure out what the plume was all about,' because if THAT'S the hole, and the casing blew out, we have an enormous problem.

    RATIGAN: ...so you're saying that the video we're all now looking at right now is not the only leak, is that what you're saying?

    SIMMONS: That's a tiny leak, and what the scientists are saying watching this stain spread -- it's now bigger, I gather, than Maryland and Delaware, and several hundred feet thick, and it's gooey stuff -- that's NOT coming out of there; they think that it's flowing at 120,000 barrels a day. It would almost have to be that big to flow that wide.

    RATIGAN: And where do you believe the second outlet is relative to what we're seeing on the video, Matt?

    SIMMONS: What the research vessel found a week ago Sunday [referring to news reports of May 16, 2010] was this giant plume about six miles away, and then this huge layer of goo on the ocean floor... that's almost certain- I mean, maybe it's a natural fracture -- I think that's where the wellhead is.
