Yes I know the location makes it difficult but there are plenty of ROVs that can operate at that depth, and I'm pretty sure that $ can get them there quickly. I was just surprised at the low flow rate. The upper well casing is supposed to be around 20" diameter, so either the pressure differential is quite low, or the leak is not coming from the full diameter. Some speculation I've read seems to think the blowout is outside the casing, and was due to the last injection of casing cement somehow blowing out. At any rate, the BOP structure is quite tall, on the order of 30-40 feet or so, so burying something that high would take a a fair sized bladder. The real issue is what the pressure would build to. A low flow might simply be the result of dynamic pressure loss of the long column of very viscous fluid flowing up the casing (I'm not sure what they expect to pump out of these wells as a flow rate, and the lower casings are smaller than 20"). If the static pressure once the flow stopped built up to several 1000 psi differential to the ocean floor, that is a bit difficult to deal with. The pressure might already be high if the leak opening is quite small. You would think they have some video of the leak source by now.
