There remain more questions than answers at this point, but the BP spin from yesterday that “Top Kill” was working appears to have been a falsehood. BP is not the right source for what the actual data from the well head means, but unfortunately they are the only source of said data.
I would like to offer interested readers a couple of better sources of technical information.
Apparently what this is showing now (11:02 AM Pacific time) is alot of drilling mud being ejected. This mud is what is intended to counteract the upward pressure from the oil reserve and if it does not stop coming out then “top kill” attempt one will have failed.
