BP, Feds don’t know what’s causing pressure drop: “We’re concerned about the vital signs of this well. We continue to be concerned about the vital signs.”

We’re trying to do two things while the evaluation of alternatives is going on. We have the opportunity to develop more vital signs for the well, one of them being to remove all foreign objects — all foreign liquids from the current well, flush it, and fill it with seawater, so we have exactly the same density of material inside and outside the BOP that will allow us to do an ambient pressure test to see if there’s any kind of pressure, a rise or fall related to something other than what we believe now to be the gas bubbles that are escaping and causing the drop in pressure.

Webmaster's Commentary: 

Here is what I think happened.

The MMS paperwork for the Macondo well complex indicates two wells were drilled. Early in the year, the "A" well was drilled, but ran into trouble and was abandoned. Then the "B" well was drilled, which resulted in the destruction of the Deepwater Horizon drilling rig and the massive blowout.

We know that the pipe and well casing for well "B" was destroyed in at least one location about 1000 feet below the floor of the Gulf of Mexico. This was the reasn for the failure of the first "Top Kill" procedure.

CNN reported on two other potential leaks at 9,000 feet and 17,000 feet.

Therefore, it made no sense to try to cap the well July 15th, much less to claim a success, unless BP pulled a fast one and switched the ROV camera back to the abandoned Well "A", and capped that for the benefit of the TV audience. This ia borne out by the navigation data for the ROVs which show the ROV camera showing the cap located well away from the blown out Deepwater Hporizon well "B", at the location for well "A".

But remember, well "A" was abandoned after it ran into trouble, so I think the pipe and casing for well "A" is also damaged, and BP wasn't prepared to deal with both well being blown out below the surface.
