Shelburn,
In the most recent press conference (Monday) Suttles indicates they no longer believe the
kink in the riser and/or the riser itself are restricting much flow. Now whether that is due to
erosion or it was always that way, he didn't say.

That's a tiny bit of good news because if the top kill fails, BP feels like it's an acceptable option to cut off the riser and stick a new riser on it.

It looks like the next sequence of events (as of that call) -

1) Top Kill Wednesday
2) If fails, top hat over the BOP
3) Junk shot + Top Kill

I couldn't get much technical out of the press conference.

The idea that there are restriction downhole is interesting and there was a very early report, when they first reinstalled the control pod that the pressure at the BOP was 14,000 psi. A few days later a more official report stated 8,000 to 9,000 psi. I kind of dismissed the earlier report but maybe it was correct.

I got the impression from what he said (why, why no numbers for us techno-nerds??) that the pressure at the BOP keeps dropping which can only be a drop in formation pressure or restrictions below the BOP, or a bit of both. Or a leak going into another formation - real bad news.

On this next I am way out of my comfort zone and would like a comment from some of the downhole experts.

IF the leakage is through the annulus and IF they can configure the choke and kill lines to enter the main bore and IF there is blockage at the formation level then doesn't that actually give the top kill a real chance at success since it won't have to fight the outflow of oil/gas?

Could this be the best news we heard since this all started?

BP staff will begin testing to see if they can actually inject mud at each of the five entry points that could be used in the top kill.

They will also take a reading of the static pressure and a reading of the pumping pressure at each of the valves./
