OK....I did some checking about when they would be doing the flushing and "fishing" to get the drill out which is blocking inside the BOP....they
have already finished the flushing and the ambient testing, which ended this morning....they replaced whatever was in the well with sea water....now,
they just started fishing ops to get the drill....so I think that is what is all the commotion down there....Here is part of the briefing from Kent
Wells about it.
Press Briefing August 19 2010
So then, what we are – here we are on the 19th of August, and what we did last night was we flushed out the BOP. And so, basically, by pumping down
from the Q4000 into the choke-and-kill lines of the BOP, we flushed what was ever in the BOP and the capping stack up to the Enterprise, because we
had hooked the Enterprise on top. So, we’d flushed out the hydrocarbons that were in there, some mud that was in there, any fluids that were in
there, and replaced that with seawater.
And so, now what we did, at about 6:30 this morning, we started an ambient test. And, the purpose of this ambient test is to actually take it down to
the point that if we were to open everything up, either by opening all the valves or actually removing the BOP, we want to have confidence that the
well wouldn’t flow. And so, we’re going to do that for a 48-hour period.
And, the reason we’ve chosen 48 hours, that’s about twice as long as it would take us to actually remove the BOP if we choose to do so. So, it’s
just giving us a safety margin. So, I think you can sort of see the steps we’ve taken to get us where we are today. So, the ambient test will finish
up Saturday morning.
At that point, what we’ll start to do then is to see if we can remove the drill pipe that is in the Macondo BOP. And, what we’ll do with that is
we’ll move the Enterprise over top, we’ll open the rams in the capping stack, so the
capping stack will remain in place, but we’ll open those rams and then go down with drill pipe and look to pick out what’s ever in the top of the
BOP.
Now, the term fishing, this is a technique we use in our industry. We’ve used it for decades. We’ve fished everything from drill pipe, to tubing,
to casing; you name it, we’ve done it over time. There is, once again, a real specialty; we have experts in the industry, we have all sorts of
different tools that can help us pick up pieces of equipment that are in different shapes and sizes, et cetera.
And so, we will be looking to do that after Saturday morning. After the ambient test is done, we’ll start that fishing operation. And, once again,
that operation could take a few days, just depending upon how things go.
Now, if we successfully remove the drill pipe, or get ourselves to where we’re confident that we think we could remove the BOP, then what we’d do
is we would use the Enterprise to first remove the capping stack off; remember, it would have already been opened. And then, we would use the Q4000 to
actually remove the Macondo BOP, and we’ll bring that to surface. And then, we will replace it with the BOP from the DD2, which is drilling the
second relief well. And so, that would be the plan of action over the next number of days, week – however long it would take to get there.
Now, so then I have to go back and talk about the two relief wells. So, the DD2, which is on the second relief well, what we’re going to do there is
we’re going to suspend the wellbore, similar to what we do when we move off for a hurricane, where we put a storm packer down in the well. And,
we’ll actually move off the well and take the BOP with it, and that would be the BOP that would be put back on the Macondo well. Of course, you
remember, the second relief well has got its casing set and cemented, et cetera, there’s no open hole there.
On the first relief well, the DD3, is still about three-and-a-half feet horizontally away from the Macondo well. It’s about 50 feet vertically from
where we expect to intersect. And, we’re sitting there ready to intersect
whenever we decide it’s prudent to go forward with, at that point. And so, we’re well positioned there.
So, you can sort of see how we got to where we are today. Once we got the Macondo well cemented, it gave us more time to be quite thoughtful and
pragmatic about how we’ve gone about – how we’re thinking about and going about how we’re actually going to ultimately kill the well, and
that’s what we’ve been doing. And, the near-ambient and ambient tests have been things to help us best understand how to go forward. And, I think
we’re well positioned, at this point.Link to source
