BP Gulf Oil Spill Static Kill Has Failed And Created Mess That Will Make Well Harder To Seal
Drilling Experts Says BP Well Is Not Dead, Static Kill has Failed, and BP Needs To Answer Questions About Clouds Coming From Sea Floor.
Oil Industry Expert Bob Cavnar has posted a series of blog posts over the last few days that have escalated in charges that BP and the Federal Government BP and the Federal Government are deliberately providing the public with misinformation to cover up the fact that the static kill has backfired and made the BP Gulf Oil Spill well much harder to kill.
In a few of those posts Bob Cavnar says BP needs to explain the huge clouds coming from the sea floor that I have pointed out here, here, here, here, and here.
In his post BP: “Well is Static” US: “Oil is Gone” Nothing to See Here. Move Along he writes the following.
At 1 am today, we got the “everything is fine” press release from BP proclaiming that the well, after the “textbook” static kill, is static. They studiously avoided the words “dead” or “killed”. Per usual, they also provided no further information. I was watching the feeds of the worsening leak coming from the lower flex joint flange at the moment I got the press release. Odd. If the well is static, then why is the wellhead leaking? Also, the leaking fluid is rising, indicating hydrocarbons, and continues even at this moment. This whole operation has given me the willies.
…
BP has violated this principle in spades by doing what they are doing. Now that they’ve proclaimed the well is “static”, they’ve also gone radio silent with no press conferences or technical McBriefings scheduled for today. Admiral Allen is doing a victory lap at this moment during the White House briefing, also not giving any data, besides just saying that it’s static with seawater. Again, if that was true, why is the wellhead leaking? To be clear, dead means dead. If it’s leaking oil, that means it’s not dead.
…
I’m sitting here watching oil leaking from a well that is supposedly dead. I’m listening to Admiral Allen saying the well is dead and to Jane Lubchenco and Carol Browner seriously contending that almost 4 million barrels of oil have disappeared. Is it just me, or are we watching the Matrix in real life?
That post was followed up by Questions BP Needs to Answer in which he again alludes to the fact the BP and Government are not being transparent about the the success of the static kill and pointing out once again that oil is still leaking from the well and that there are the huge clouds coming from the sea floor.
Since announcing success (sort of) of the static kill, MSM attention has dropped to virtually zero, though the well is obviously far from static, judging from the huge clouds in the water around the wellhead and manifold, as well as numerous ROVs surrounding the wellhead, providing no feeds to the public. The media has payed virtually no attention to these feeds and has asked no questions of Adm Allen or BP. BP has stopped briefing the public daily.
The problem is that there are lots of questions that remain unanswered. Here’s what I want to know:
•Is the well dead?
•What is the pressure on the well? Now?
•If the well is open to the surface, what is that pressure?
•…
•How do you know all the cement went down the casing?
•…
•Why is the flex joint flange leaking?
•Why are the ROV feeds no longer provided in a decipherable resolution?
•Why are some ROV feeds not being provided?
•…
•Why are clouds of debris continuing to obscure the view several days after the well was supposedly “static”?
Until these questions are answered by BP, we have no real information to tell us that the well is dead, or even safe. As long as they continue to stonewall critical data, I’ll only continue to believe that the well is not “static” or safe.
Not only are the ROV feeds high pixelated to the point the screens can not be read BP has still not shown the BOP where a methane leak was discovered just inches from the well head
and BP is playing with the lighting to hide huge clouds shooting out of the sea floor and has even been caught applying filters in real time on the feeds to remove hydrates shooting out of the sea bed from the video feeds.
A comment on that post by fishgrease, an oil industry expert from over at the dailykos, responding to an attack on Cavnar’s post also agrees to the fact that the well is not dead.
They froze their chokes off this morning. The ones atop the Capping Stack. If you think that means this is a dead well,
1.You don’t know anything about oil, and/or gas wells.
2.You’re an idiot.
3.Both
Cavnar also posted the following response to the same person.
Mike,
A couple of questions for you:
1.If the “well is as dead as dead can be”, why does it have 4,200 psi on it, 2,000 psi more than seawater hydrostatic, and 600 psi more than 14 ppg mud hydrostatatic from the riser?
2.If the well is dead, why are they now “pressure testing” said dead well?
3.Both
That conversation was followed up with a new post from Bob Cavnar pointing out the fact that BP is conducting pressure tests indicates that the well is not dead and that BP and the Federal Government are deceiving the public about the real reasons the tests are being performed.
Adm Allen just finished his morning presser where he just casually mentioned that they are going to “test” the old BOP and capping stack and take pressure readings to determine if the hydrocarbons in the annulus are “dormant” or if they’re connected to the reservoir. Translation: “BP continues to have pressure on the wellhead from down below and have been letting me believe for a week that the well is static.” Of course, they’ve never disclosed not one bit of pressure data after the “well integrity test”, and even that “data” was sparse.
Yesterday, during his presser, the Admiral was asked about releasing the pressure readings and un-blurring the ROV feeds. The Admiral said he would check into the feeds and get BP to disclose the pressures. Of course, neither happened, and now he drops the bomb that they’re back to the ol’ BOP test again. That means they have no idea where the static kill and cement went.
Today Cavnar’s series of posts culminated to the conclusion that the Feds are deliberately putting out misinformation to hide the fact that the well is communicating with the reservoir, static kill has backfired miserably and the failure of static kill leaves BP and the Federal Government with no idea what to do next.
For the last several days, I’ve been trying to figure out what BP is doing and what is the actual condition of BP’s MC252 well after their “static kill” and cementing procedure last week apparently didn’t work.
…
On August 2nd and 3rd, BP ran the “static kill” pumping 2,300 barrels of mud. Early in the morning on the 4th, BP issued a press release saying the the well had reached a “static condition” with well pressure “controlled by the hydrostatic pressure of the drilling mud.” In his McBriefing later that day, Wells actually said that when they pumped the mud, they could actually see it go into the reservoir by pressures, and that they pumped up to 15 barrels per minute.
…
All was right with the world. Except, it wasn’t. Day before yesterday, Adm. Allen announced they were going to start a “pressure test”, babbling about the annulus and raising the ominous spectre that they are still actually communicated to the reservoir. Wells confirmed that fear in the afternoon, admitting that they indeed had 4,200 psi on the well when it’s supposed to be dead.
…
What’s going on here is that the “static kill” looks like it did the opposite of what BP and Allen had suggested at the beginning.
…
The mis-information and confusion is also taking its toll.
…
In actuality, this “static kill” did nothing that BP and Allen said it would do. Certainly the well is not dead or “static”.
BP and the government don’t really have a clue where the 2,300 barrels of mud and 500 barrels of cement went. They originally claimed it all went down the casing and out to the reservoir. I would set the probability of that actually having happened at zero… There is no way, unless that entire float assembly blew off, that they pumped down the casing and up the backside. On top of all that, there are HUGE lost circulation zones both below and above the reservoir.
…
So, where did all the mud and cement go? It likely went down the backside of the production casing and either out through some damage that was caused during the aborted top kill, or out the lost circulation zone right below the 9 7/8″ liner at 17,100. The fact that they’re getting pressure now tells me that they are indeed communicated to the reservoir below, probably obscured by the fact that they now have mud strung through the annulus. If they are indeed communicated, pressure will build on the wellhead, which is exactly what’s happening. Adm. Allen pledged to get BP to release the pressure data 3 days ago. The next day, when asked about it, he said it was released, but “nobody can find it.” The data is still AWOL.
As Washington’s blog points out:
BP has tried to cover up every aspect of the spill. See this, this and this.
The bottom kill – the procedure which all oil industry experts agree has the best chance of killing the leak – hasn’t yet been performed. The underwater cameras still show methane and oil leaking into the Gulf.
And yet the country’s attention is already drifting away from the Gulf and to celebrities, stocks, and other issues.
I’m beginning to wonder whether BP keeps on doing one confusing procedure after another, and keeps on saying that the well has been capped, hoping that everyone stops paying attention so that BP can just pack up its bags and slink away while people aren’t paying attention.
Relief wells are the best hope for permanently capping the well. But it is possible that BP has messed up the well so badly that the relief wells will fail.
As Cavnar notes, BP has already taken down or blurred most of its underwater camera feeds. BP might just declare “mission accomplished” and skip the relief wells, leaving a ticking time bomb which will pollute the Gulf for years to come.
Fishgrease, another oil industry expert that I mentioned earlier weighs in on the issue of the open communication that has caused a the choke line to freeze up and led to a new leak in the well.
I awoke early this morning to find they’ve got a hell of a pressure drop across those chokes on the capping stack…. those new ones they installed because the brand fucking new automated valves below them all failed and now require manual locks.
An ROV using a methanol hot-stab to try to thaw a choke out. Get this. It was poking the hot-stab INTO the end of the choke pipe! That’s right! They’re idiots! For that choke to freeze up like that (there were patches of external ice indicating it got pretty damned cold) there had to be a significant pressure drop across it. Pouring methanol into the low pressure end of that choke pipe is just… it’s fucking funny!
So now they got themselves a good old problem. We can’t see it, of course, and we’ll never get any pressure readings that will tell us exactly what sort of pressure drop caused those chokes to freeze. But let me tell you something that is true as death… it’s a LOT more hydrocarbon pressure then can be explained by anything residual in the BOP. The annulus is open to the reservoir and always has been.
Fishgrease’s comment was about the leak shown in this video.
The observation by fishgrease led to the following discussion from The Oil Drum community on the live chat about the issue.
[22:53] I should show a little respect. I mean, life isn’t just “one big cruise,” is it, TOB_ ?
[22:53] that was after they had to apply a fix to the valve underneath it, which had been probably damaged by clathrates
[22:53] I have 35-40 pics of bubbles coming from that choke pipe…
[22:53] okay.
[22:54] heh heh heh cigarette break
[22:54] when did they fix the valve? was that part of what i was staring at (mindlessly) last night?
[22:54] aviva: yeah, oi2 was holding onto a thing they stuck in the valve while oi1 had to adjust gauges and things
[22:55] What was the annulus question?
[22:55] anyway, after all that, apparently, according to dkos fishgrease, who got up to pee at 2 in the morning and glanced at the feeds
[22:55] yes….
[22:56] dkos, *eyes glaze over*
[22:56] one of the rovs was sticking a hot stab into that little chimney up there
[22:57] okay… you mean the curved one? the choke pipe?
[22:57] and releasing that stuff (i’m braindead) that melts ice into it
[22:57] aviva: yes
[22:57] methanol.
[22:57] TOB_ : I’d commented to CBLuc: “I’m not sure there’s been a lot of concern about cement in the annulus (from Halliburton/April), but more with the cement shoe.” (in reply to his concerns) and you wrote back: “That is the question, aviva.” Or something similar.
[22:58] TOB_: yes, thank you
[22:58] Okay, so they injected methanol in the choke pipe, which is outgassing methane (probably; it’s totally translucent emissions)
[22:58] and…
[22:59] what’s fishgrease thinking? or wondering?
[22:59] == SJFriedl [~Steve@ylnat.unixwiz.net] has quit [Quit: Leaving]
[22:59] Right, that is the big question.
[22:59] the question is why would the choke be releasing something that would indicated it’s icing up with clathrates on the inside?
[23:00] I think it’s the big question that they’ve shared with us, TOB_ . There may be others…
[23:00] Lot’s of other big questions remaining.
[23:01] fishgrease is proposing (and even tho he can get a little overpassionate, he knows this stuff) that the upper stack is under negative pressure
[23:01] There may be residual (trapped) hydrocarbons in the BOP and capping stack… hydrocarbons that are unlikely to be flowing up from the reservoir, but are still under some pressure and emerging from the capping stack…
[23:02] What does fishgrease say is causing the negative pressure in the upper stack?
[23:02] negative pressure?
[23:03] Does he think that the ambient pressure around the capping stack is squeezing it?
[23:03] negative pressure would cause those leaks that we’ve watched leak oil outward leak water inward instead
[23:03] Are asking why there would be hydrates in the choke line?
[23:03] TOB_: yes
[23:03] aviva: yes
[23:03] Oh. I see. And fishgrease is concerned that seawater oozing into the choke line is causing hydrates to grow…
[23:04] The pipe is full of water, when the little methane bubbles interact they form the hydrates.
[23:04] aviva: and wondering if they started the negative pressure test (which they said they would start after the storm) yesterday
[23:05] I can’t believe they’d start the negative pressure test — and then proclaim, in three briefings (2 for Allen, 1 for Wells) that they’re waiting until the storm’s over.
[23:05] It’s open to the seawater.
[23:07] Just a trickle of bubbles.
[23:07] or if they’re not already doing the negative pressure test, what else could cause the stack to go from being kept at positive pressure to being at negative pressure?
[23:08] TOB_: but the point has been to not let the stack go negative until they could do it under control, because it’s a pretty dangerous test to do
[23:10] == PhilMB [47f2a88d@gateway/web/freenode/ip.71.242.168.141] has joined #theoildrum
[23:10] I believe they are referring to pump pressure. Easing it off. Negative in relation to the reservoir pressure.
[23:11] the reason to do a negative pressure test is to see if, when they decrease the pressure, the force from the bottom will push back

[23:38] yuriwho: if things were the way they were supposed to be, after the positive pressure test, there would still be some positive pressure in the top of the stack, right?
[23:38] I don’t totally follow fishgrease’s entire reasoning here… but I won’t be surprised to discover that the annulus is open to the reservoir. I don’t expect it, exactly. But it’s still a possibility, as Allen stated in his briefing. Not probable, but possible.
[23:38] == overdub [~nomad@bas1-toronto05-1176310987.dsl.bell.ca] has quit [Ping timeout: 245 seconds]
[23:39] if the valve is frozen, thats because some gas is leaking through it causing the refrigeration effect (joule-thompson effect) which means that there is a increasing load of pressure building up inside the stack due to communication from the formation to the top
[23:39] Yep, possible. But they pumped a lot of cement in there.
[23:39] yuriwho: so it’s still positive pressure pushing from the inside to the outside?
[23:40] um… communication from the formation to the top? if it’s that obvious, why are allen and wells speaking of it as a highly remote possibility that must be checked, but isn’t likely?
[23:40] == Derek_ [~Derek@c-98-235-202-26.hsd1.pa.comcast.net] has quit [Ping timeout: 265 seconds]
[23:40] whether it is through the cememnt or from the annulus is a different question. It could be that the main casing string is plugged and it is slowly leaking up the annulus
[23:40] yes evergreen, that is what he is thinking
[23:41] yuriwho: i think what mixed me up was i was thinking it was negative pressure on the inside causing water to leak into the stack
[23:42] nope, has to be pressure leaking out. It would not get cold and freeze unless that pressure was building
[23:42] now i get it!!!
[23:42] If it was a leak, it was more like a trickle.
[23:42] it would only be a trickle prehaps up the choke
[23:42] == overdub [~nomad@bas1-toronto05-1176310987.dsl.bell.ca] has joined #theoildrum
[23:43] yuriwho, reading between the lines of allen’s briefing on august 10, do you think he believes that there’s a reasonable chance of communication from formation to capping stack? and up the annulus, most probably? Is he totally minimizing things?
[23:43] btw, his other comment about meeting the guys for coffee……thats his group of industry consultants who work for the service providers i the gulf
[23:44] personally I think there is a slow leak up the annulus, the pressure is only starting to build up now
[23:44] it’s when he said “pressure drop across it” that threw me, i translated that incorrectly inside my head
[23:46] imagine that the choke valve leaks gas slowly, if pressure is building on one side you get gas leaking and refridgeration occurs
[23:46] and he was actually more unnerved by their trying to stop it using methane than the fact that it’s there
[23:47] yuriwho: which is just a similar thing to what’s been happening all along, just a different version
[23:47] == rob___ [6de08ef6@gateway/web/freenode/ip.109.224.142.246] has joined #theoildrum
[23:48] slow leak up the annulus relates to what folks were talking about here about two hours ago
[23:48] that means there must be a place where the annulus under the wellhead is communicating with what’s above it
[23:49] could be where they never installed that locking ring
[23:49] yuriwho: right
[23:49] if it’s a slow leak it will be hard and slow to kill
[23:49] without opening up the well
[23:50] i had just gotten to that part of how they drill the well in that big document. i never understood how the well head was put together
[23:50] yea that pdf is excellent at explaing the fundamentals of well construction

[23:51] Speaking of the stack…where is it?
[23:51] heh, I just woke up……fell asleep after my sons soccer game tonight <–coach and ref…..got tired
[23:52] yuriwho: so if there’s a slow leak up the annulus it could help the relief well effort kinda sorta by providing a flow pressure upward
[23:52] perhaps too slow to get cement to move. Depends on how open it is
[23:53] but the problem is dealing with the wellhead could be quite problematic
[23:53] == overdub [~nomad@bas1-toronto05-1176310987.dsl.bell.ca] has joined #theoildrum
[23:54] they might have to pull both BOP’s and cement up past the leak point to the annulus.

On August 2nd and 3rd, BP ran the “static kill” pumping 2,300 barrels of mud. Early in the morning on the 4th, BP issued a press release saying the the well had reached a “static condition” with well pressure “controlled by the hydrostatic pressure of the drilling mud.” In his McBriefing later that day, Wells actually said that when they pumped the mud, they could actually see it go into the reservoir by pressures, and that they pumped up to 15 barrels per minute.
…
All was right with the world. Except, it wasn’t. Day before yesterday, Adm. Allen announced they were going to start a “pressure test”, babbling about the annulus and raising the ominous spectre that they are still actually communicated to the reservoir. Wells confirmed that fear in the afternoon, admitting that they indeed had 4,200 psi on the well when it’s supposed to be dead.
…
What’s going on here is that the “static kill” looks like it did the opposite of what BP and Allen had suggested at the beginning.
…
The mis-information and confusion is also taking its toll.
…
In actuality, this “static kill” did nothing that BP and Allen said it would do. Certainly the well is not dead or “static”.
BP and the government don’t really have a clue where the 2,300 barrels of mud and 500 barrels of cement went. They originally claimed it all went down the casing and out to the reservoir. I would set the probability of that actually having happened at zero… There is no way, unless that entire float assembly blew off, that they pumped down the casing and up the backside. On top of all that, there are HUGE lost circulation zones both below and above the reservoir.
…
So, where did all the mud and cement go? It likely went down the backside of the production casing and either out through some damage that was caused during the aborted top kill, or out the lost circulation zone right below the 9 7/8″ liner at 17,100. The fact that they’re getting pressure now tells me that they are indeed communicated to the reservoir below, probably obscured by the fact that they now have mud strung through the annulus. If they are indeed communicated, pressure will build on the wellhead, which is exactly what’s happening. Adm. Allen pledged to get BP to release the pressure data 3 days ago. The next day, when asked about it, he said it was released, but “nobody can find it.” The data is still AWOL.
As Washington’s blog points out:
BP has tried to cover up every aspect of the spill. See this, this and this.
The bottom kill – the procedure which all oil industry experts agree has the best chance of killing the leak – hasn’t yet been performed. The underwater cameras still show methane and oil leaking into the Gulf.
And yet the country’s attention is already drifting away from the Gulf and to celebrities, stocks, and other issues.
I’m beginning to wonder whether BP keeps on doing one confusing procedure after another, and keeps on saying that the well has been capped, hoping that everyone stops paying attention so that BP can just pack up its bags and slink away while people aren’t paying attention.
Relief wells are the best hope for permanently capping the well. But it is possible that BP has messed up the well so badly that the relief wells will fail.
As Cavnar notes, BP has already taken down or blurred most of its underwater camera feeds. BP might just declare “mission accomplished” and skip the relief wells, leaving a ticking time bomb which will pollute the Gulf for years to come.
Fishgrease, another oil industry expert that I mentioned earlier weighs in on the issue of the open communication that has caused a the choke line to freeze up and led to a new leak in the well.
I awoke early this morning to find they’ve got a hell of a pressure drop across those chokes on the capping stack…. those new ones they installed because the brand fucking new automated valves below them all failed and now require manual locks.
An ROV using a methanol hot-stab to try to thaw a choke out. Get this. It was poking the hot-stab INTO the end of the choke pipe! That’s right! They’re idiots! For that choke to freeze up like that (there were patches of external ice indicating it got pretty damned cold) there had to be a significant pressure drop across it. Pouring methanol into the low pressure end of that choke pipe is just… it’s fucking funny!
So now they got themselves a good old problem. We can’t see it, of course, and we’ll never get any pressure readings that will tell us exactly what sort of pressure drop caused those chokes to freeze. But let me tell you something that is true as death… it’s a LOT more hydrocarbon pressure then can be explained by anything residual in the BOP. The annulus is open to the reservoir and always has been.
Fishgrease’s comment was about the leak shown in this video.
The observation by fishgrease led to the following discussion from The Oil Drum community on the live chat about the issue.
[22:53] I should show a little respect. I mean, life isn’t just “one big cruise,” is it, TOB_ ?
[22:53] that was after they had to apply a fix to the valve underneath it, which had been probably damaged by clathrates
[22:53] I have 35-40 pics of bubbles coming from that choke pipe…
[22:53] okay.
[22:54] heh heh heh cigarette break
[22:54] when did they fix the valve? was that part of what i was staring at (mindlessly) last night?
[22:54] aviva: yeah, oi2 was holding onto a thing they stuck in the valve while oi1 had to adjust gauges and things
[22:55] What was the annulus question?
[22:55] anyway, after all that, apparently, according to dkos fishgrease, who got up to pee at 2 in the morning and glanced at the feeds
[22:55] yes….
[22:56] dkos, *eyes glaze over*
[22:56] one of the rovs was sticking a hot stab into that little chimney up there
[22:57] okay… you mean the curved one? the choke pipe?
[22:57] and releasing that stuff (i’m braindead) that melts ice into it
[22:57] aviva: yes
[22:57] methanol.
[22:57] TOB_ : I’d commented to CBLuc: “I’m not sure there’s been a lot of concern about cement in the annulus (from Halliburton/April), but more with the cement shoe.” (in reply to his concerns) and you wrote back: “That is the question, aviva.” Or something similar.
[22:58] TOB_: yes, thank you
[22:58] Okay, so they injected methanol in the choke pipe, which is outgassing methane (probably; it’s totally translucent emissions)
[22:58] and…
[22:59] what’s fishgrease thinking? or wondering?
[22:59] == SJFriedl [~Steve@ylnat.unixwiz.net] has quit [Quit: Leaving]
[22:59] Right, that is the big question.
[22:59] the question is why would the choke be releasing something that would indicated it’s icing up with clathrates on the inside?
[23:00] I think it’s the big question that they’ve shared with us, TOB_ . There may be others…
[23:00] Lot’s of other big questions remaining.
[23:01] fishgrease is proposing (and even tho he can get a little overpassionate, he knows this stuff) that the upper stack is under negative pressure
[23:01] There may be residual (trapped) hydrocarbons in the BOP and capping stack… hydrocarbons that are unlikely to be flowing up from the reservoir, but are still under some pressure and emerging from the capping stack…
[23:02] What does fishgrease say is causing the negative pressure in the upper stack?
[23:02] negative pressure?
[23:03] Does he think that the ambient pressure around the capping stack is squeezing it?
[23:03] negative pressure would cause those leaks that we’ve watched leak oil outward leak water inward instead
[23:03] Are asking why there would be hydrates in the choke line?
[23:03] TOB_: yes
[23:03] aviva: yes
[23:03] Oh. I see. And fishgrease is concerned that seawater oozing into the choke line is causing hydrates to grow…
[23:04] The pipe is full of water, when the little methane bubbles interact they form the hydrates.
[23:04] aviva: and wondering if they started the negative pressure test (which they said they would start after the storm) yesterday
[23:05] I can’t believe they’d start the negative pressure test — and then proclaim, in three briefings (2 for Allen, 1 for Wells) that they’re waiting until the storm’s over.
[23:05] It’s open to the seawater.
[23:07] Just a trickle of bubbles.
[23:07] or if they’re not already doing the negative pressure test, what else could cause the stack to go from being kept at positive pressure to being at negative pressure?
[23:08] TOB_: but the point has been to not let the stack go negative until they could do it under control, because it’s a pretty dangerous test to do
[23:10] == PhilMB [47f2a88d@gateway/web/freenode/ip.71.242.168.141] has joined #theoildrum
[23:10] I believe they are referring to pump pressure. Easing it off. Negative in relation to the reservoir pressure.
[23:11] the reason to do a negative pressure test is to see if, when they decrease the pressure, the force from the bottom will push back

[23:35] he’s saying that there is a large pressure variation at the new choke valves, more than there should be if it was just pressure from residual oil in the top of the well after cementing

[23:38] yuriwho: if things were the way they were supposed to be, after the positive pressure test, there would still be some positive pressure in the top of the stack, right?
[23:38] I don’t totally follow fishgrease’s entire reasoning here… but I won’t be surprised to discover that the annulus is open to the reservoir. I don’t expect it, exactly. But it’s still a possibility, as Allen stated in his briefing. Not probable, but possible.
[23:38] == overdub [~nomad@bas1-toronto05-1176310987.dsl.bell.ca] has quit [Ping timeout: 245 seconds]
[23:39] if the valve is frozen, thats because some gas is leaking through it causing the refrigeration effect (joule-thompson effect) which means that there is a increasing load of pressure building up inside the stack due to communication from the formation to the top
[23:39] Yep, possible. But they pumped a lot of cement in there.
[23:39] yuriwho: so it’s still positive pressure pushing from the inside to the outside?
[23:40] um… communication from the formation to the top? if it’s that obvious, why are allen and wells speaking of it as a highly remote possibility that must be checked, but isn’t likely?
[23:40] == Derek_ [~Derek@c-98-235-202-26.hsd1.pa.comcast.net] has quit [Ping timeout: 265 seconds]
[23:40] whether it is through the cememnt or from the annulus is a different question. It could be that the main casing string is plugged and it is slowly leaking up the annulus
[23:40] yes evergreen, that is what he is thinking
[23:41] yuriwho: i think what mixed me up was i was thinking it was negative pressure on the inside causing water to leak into the stack
[23:42] nope, has to be pressure leaking out. It would not get cold and freeze unless that pressure was building
[23:42] now i get it!!!
[23:42] If it was a leak, it was more like a trickle.
[23:42] it would only be a trickle prehaps up the choke
[23:42] == overdub [~nomad@bas1-toronto05-1176310987.dsl.bell.ca] has joined #theoildrum
[23:43] yuriwho, reading between the lines of allen’s briefing on august 10, do you think he believes that there’s a reasonable chance of communication from formation to capping stack? and up the annulus, most probably? Is he totally minimizing things?
[23:43] btw, his other comment about meeting the guys for coffee……thats his group of industry consultants who work for the service providers i the gulf
[23:44] personally I think there is a slow leak up the annulus, the pressure is only starting to build up now
[23:44] it’s when he said “pressure drop across it” that threw me, i translated that incorrectly inside my head
[23:46] imagine that the choke valve leaks gas slowly, if pressure is building on one side you get gas leaking and refridgeration occurs
[23:46] and he was actually more unnerved by their trying to stop it using methane than the fact that it’s there
[23:47] yuriwho: which is just a similar thing to what’s been happening all along, just a different version
[23:47] == rob___ [6de08ef6@gateway/web/freenode/ip.109.224.142.246] has joined #theoildrum
[23:48] slow leak up the annulus relates to what folks were talking about here about two hours ago
[23:48] that means there must be a place where the annulus under the wellhead is communicating with what’s above it
[23:49] could be where they never installed that locking ring
[23:49] yuriwho: right
[23:49] if it’s a slow leak it will be hard and slow to kill
[23:49] without opening up the well
[23:50] i had just gotten to that part of how they drill the well in that big document. i never understood how the well head was put together
[23:50] yea that pdf is excellent at explaing the fundamentals of well construction

[23:51] Speaking of the stack…where is it?
[23:51] heh, I just woke up……fell asleep after my sons soccer game tonight <–coach and ref…..got tired
[23:52] yuriwho: so if there’s a slow leak up the annulus it could help the relief well effort kinda sorta by providing a flow pressure upward
[23:52] perhaps too slow to get cement to move. Depends on how open it is
[23:53] but the problem is dealing with the wellhead could be quite problematic
[23:53] == overdub [~nomad@bas1-toronto05-1176310987.dsl.bell.ca] has joined #theoildrum
[23:54] they might have to pull both BOP’s and cement up past the leak point to the annulus.

'Afmaken tweede oliebron blijft noodzakelijk'
Uitgegeven: 13 augustus 2010 22:08
Laatst gewijzigd: 13 augustus 2010 22:08
AMSTERDAM - De lekkende oliebron van oliemaatschappij BP in de Golf van Mexico is nog altijd niet permanent afgesloten. Het is dan ook noodzakelijk dat het boren van een tweede bron door blijft gaan, zodat de bron van onderaf kan worden afgesloten.
Đ Getty ImagesDat heeft de federale regering van de Amerikaanse staat Louisiana vrijdag gezegd.
Deskundigen zijn nog steeds aan het bekijken op welke manier de tweede bron het beste kan worden afgemaakt.
Dat de tweede bron wordt afgemaakt is echter zeker, zo zei Thad Allen, die vanuit de regering de leiding heeft over het afsluiten van de oliebron.
Metingen
BP dacht dat modder en cement die van bovenaf in de lekkende put waren gepompt de bron feitelijk hadden afgesloten. Deskundigen hebben echter de druk onder het cement gemeten. Een stabiele druk is een teken dat het cement de bron permanent heeft afgesloten.
Tijdens het testen bleek echter dat de druk toenam, wat betekent dat er nog steeds ruimtes zijn die moeten worden afgesloten. Dit is dan ook de reden dat de bron ook van onderaf moet worden afgesloten, de zogenaamde 'bottom kill'.
Kap
Sinds 15 juli stroomt er geen olie meer uit de bron. Die dag werd er een tijdelijke kap over de put geplaatst die de stroom olie tot staan wist te brengen. Voor die tijd lekte de olie vrijwel ongehinderd de Golf van Mexico in.
Đ Novum
zoals ik al in het eerste uur schreef, en niemand mij geloofde, of bijna niemand, was het een ramp van jewelste. en zo is er nog een aantal plekken op aard die niet goed weten wat een ramp ze kunnen veroorzaken met oliewinning. laten we iets anders gaan zoeken en investeren, hebben we ook niets meer van doen met een soort van oliestaatjes.

Garnalenvissers doen eerste vangst sinds olieramp
17 augustus 2010, 10:20 uur | FD.nl
Amerikaanse garnalenvissers zeggen dat ze maandag bij de eerste vangst sinds de olieramp volop hebben gevangen en dat de garnalen vrij van olie zijn. Consumenten moeten nog overgehaald worden.
Maandag begon de garnalenvangst in Louisiana, de eerste vissoort die weer gevangen wordt in gebieden waar eerst nog olie lag. Louisiana is goed voor 70% van de garnalenvangst in de Verenigde Staten. De gehele visindustrie in de staat heeft een omzet van naar schatting $2,4 mrd per jaar.
Vissers, restauranthouders en andere aan de visindustrie gelieerde bedrijven hebben maandenlang in onzekerheid geleefd als gevolg van de olieramp in de Golf van Mexico. Grote delen van de zee waren afgezet voor visvangst, het merendeel is nu weer opengesteld.
'We zien geen olie hier. Geen teer, helemaal niets', aldus Biran Amos, een 53-jarige garnalenvisser tegen persbureau AP nadat hij de eerste vangst van het garnalenseizoen heeft gedaan. In verhalen in Amerikaanse media laten vissers blijken blij te zijn dat het normale leven weer op gang is gekomen.
'Veilig'
De Amerikaanse voedselautoriteiten zeggen dat de garnalen geschikt zijn voor consumptie. De chemicaliën die BP heeft gebruik bij het bestrijden van de olie zouden niet in de vis terecht kunnen komen, hoewel de voedselautoriteit dat nog nader gaat testen.
Wat het effect is van de olieramp op de vispopulatie op lange termijn, moet nog blijken, zegt de overheidsinstelling National Oceanic & Atmospheric Administration. De regio is ook een broedplaats voor vissen.
Het grootste probleem voor de lokale vissers is momenteel de beeldvorming rond hun vangst, blijkt uit de verhalen in Amerikaanse media. De consumptie van vis uit de Golf van Mexico is sterk gedaald. En ook al zeggen de vissers dat de vangst schoon is en bevestigen de autoriteiten dat, het zal tijd kosten voor consumenten daarvan doordrongen raken, is de verwachting.

Nog even wat extra informatie over Corexit:
wikipedia.org
Corexit[1] is a product line of solvents primarily used as a dispersant for breaking up oil slicks. It is produced by Nalco Holding Company which is associated with BP and Exxon.[2] Corexit is the most-used dispersant in the Deepwater Horizon oil spill in the Gulf of Mexico, with COREXIT 9527 having been replaced by COREXIT 9500 after the former was deemed too toxic.[3] Oil that would normally rise to the surface of the water is broken up by the dispersant into small globules that can then remain suspended in the water.[4]
Toxicity
The relative toxicity of Corexit and other dispersants are difficult to determine due to a scarcity of scientific data.[3] The manufacturer's safety data sheet states "No toxicity studies have been conducted on this product," and later concludes "The potential human hazard is: Low."[20] According to the manufacturer's website, workers applying Corexit should wear breathing protection and work in a ventilated area.[21] Compared with 12 other dispersants listed by the EPA, Corexit 9500 and 9527 are either similarly toxic or 10 to 20 times more toxic.[7] In another preliminary EPA study of eight different dispersants, Corexit 9500 was found to be less toxic to some marine life than other dispersants and to break down within weeks, rather than settling to the bottom of the ocean or collecting in the water.[22] None of the eight products tested are "without toxicity", according to an EPA administrator, and the ecological effect of mixing the dispersants with oil is unknown, as is the toxicity of the breakdown products of the dispersant.[22]
Corexit 9527, considered by the EPA to be an acute health hazard, is stated by its manufacturer to be potentially harmful to red blood cells, the kidneys and the liver, and may irritate eyes and skin.[23][14] The chemical 2-butoxyethanol, found in Corexit 9527, was identified as having caused lasting health problems in workers involved in the cleanup of the Exxon Valdez oil spill.[24] According to the Alaska Community Action on Toxics, the use of Corexit during the Exxon Valdez oil spill caused people "respiratory, nervous system, liver, kidney and blood disorders".[16] Like 9527, 9500 can cause hemolysis (rupture of blood cells) and may also cause internal bleeding.[4]
According to the EPA, Corexit is more toxic than dispersants made by several competitors and less effective in handling southern Louisiana crude.[25] On May 20, 2010, the EPA ordered BP to look for less toxic alternatives to Corexit, and later ordered BP to stop spraying dispersants, but BP responded that it thought that Corexit was the best alternative and continued to spray it.[3]
Reportedly Corexit may be toxic to marine life and helps keep spilled oil submerged. There is concern that the quantities used in the Gulf will create 'unprecedented underwater damage to organisms.'[26] Nalco spokesman Charlie Pajor said that oil mixed with Corexit is "more toxic to marine life, but less toxic to life along the shore and animals at the surface" because the dispersant allows the oil to stay submerged below the surface of the water.[27] Corexit 9500 causes oil to form into small droplets in the water; fish may be harmed when they eat these droplets.[4] According to its Material safety data sheet, Corexit may also bioaccumulate, remaining in the flesh and building up over time.[28] Thus predators who eat smaller fish with the toxin in their systems may end up with much higher levels in their flesh.[4]

The relative toxicity of Corexit and other dispersants are difficult to determine due to a scarcity of scientific data.[3] The manufacturer's safety data sheet states "No toxicity studies have been conducted on this product," and later concludes "The potential human hazard is: Low."[20] According to the manufacturer's website, workers applying Corexit should wear breathing protection and work in a ventilated area.[21] Compared with 12 other dispersants listed by the EPA, Corexit 9500 and 9527 are either similarly toxic or 10 to 20 times more toxic.[7] In another preliminary EPA study of eight different dispersants, Corexit 9500 was found to be less toxic to some marine life than other dispersants and to break down within weeks, rather than settling to the bottom of the ocean or collecting in the water.[22] None of the eight products tested are "without toxicity", according to an EPA administrator, and the ecological effect of mixing the dispersants with oil is unknown, as is the toxicity of the breakdown products of the dispersant.[22]
Corexit 9527, considered by the EPA to be an acute health hazard, is stated by its manufacturer to be potentially harmful to red blood cells, the kidneys and the liver, and may irritate eyes and skin.[23][14] The chemical 2-butoxyethanol, found in Corexit 9527, was identified as having caused lasting health problems in workers involved in the cleanup of the Exxon Valdez oil spill.[24] According to the Alaska Community Action on Toxics, the use of Corexit during the Exxon Valdez oil spill caused people "respiratory, nervous system, liver, kidney and blood disorders".[16] Like 9527, 9500 can cause hemolysis (rupture of blood cells) and may also cause internal bleeding.[4]
According to the EPA, Corexit is more toxic than dispersants made by several competitors and less effective in handling southern Louisiana crude.[25] On May 20, 2010, the EPA ordered BP to look for less toxic alternatives to Corexit, and later ordered BP to stop spraying dispersants, but BP responded that it thought that Corexit was the best alternative and continued to spray it.[3]
Reportedly Corexit may be toxic to marine life and helps keep spilled oil submerged. There is concern that the quantities used in the Gulf will create 'unprecedented underwater damage to organisms.'[26] Nalco spokesman Charlie Pajor said that oil mixed with Corexit is "more toxic to marine life, but less toxic to life along the shore and animals at the surface" because the dispersant allows the oil to stay submerged below the surface of the water.[27] Corexit 9500 causes oil to form into small droplets in the water; fish may be harmed when they eat these droplets.[4] According to its Material safety data sheet, Corexit may also bioaccumulate, remaining in the flesh and building up over time.[28] Thus predators who eat smaller fish with the toxin in their systems may end up with much higher levels in their flesh.[4]
Ja en die grotere vissen (predators) eten wij uiteindelijk weer....

Zo te zien is de bron nu definitief dicht, via de relief wells hebben ze cement weten te storten om zo de bron definitief te sluiten. Binnenkort zal dan de BOP verwijdert worden voor onderzoek?quote:BP Confirms Successful Completion of Well Kill Operations in Gulf of Mexico
Release date: 19 September 2010
HOUSTON - BP today confirmed that well kill operations on the MC252 well in the Gulf of Mexico are now complete, with both the casing and annulus of the well sealed by cement.
The MC252 well has been shut-in since July 15 and cementing operations in August, following the static kill, provided an effective cement plug in the well’s casing. The relief well drilled by the DDIII drilling rig intercepted the annulus of the MC252 well on September 15, followed by pumping of cement into the annulus on September 17. BP, the federal government scientific team and the National Incident Commander have now concluded that these operations have also successfully sealed the annulus of the MC252 well.
“This is a significant milestone in the response to the Deepwater Horizon tragedy and is the final step in a complex and unprecedented subsea operation – finally confirming that this well no longer presents a threat to the Gulf of Mexico,” said Tony Hayward, BP group chief executive. “However, there is still more to be done. BP’s commitment to complete our work and restore the damage done to the Gulf of Mexico, the Gulf coast and the livelihoods of the people across the region remains unchanged.”
BP will now proceed to complete the abandonment of the MC252 well, which includes removing portions of the casing and setting cement plugs. A similar plugging and abandonment of both relief wells will occur as well.
BP will also now begin the process of dismantling and recovering containment equipment and decontaminating vessels that were in position at the wellsite.
Surface Spill Response
Approximately 25,200 personnel, more than 2,600 vessels and dozens of aircraft remain engaged in the response effort.
No volumes of oily liquid have been recovered from the surface of the Gulf of Mexico since July 21 and the last controlled burn operation occurred on July 20. BP, as part of Unified Command, continues to conduct overflights and other reconnaissance to search for oil on the surface. At peak, approximately 3.5 million feet of containment boom was deployed in response to the oil spill. Currently 670,000 feet of containment boom remains deployed.
Additional information
On August 23 processing of claims from individuals and businesses related to the Deepwater Horizon incident transferred to the Gulf Coast Claims Facility (GCCF). To date, over 68,000 claims have been submitted to the GCCF, with over 19,000 claims totaling over $240 million being paid, including a $34.5 million fund for real estate brokers and agents. Prior to the transfer to the GCCF, BP had made 127,000 claims payments, totalling approximately $399 million.
The cost of the response to September 17 amounts to approximately $9.5 billion, including the cost of the spill response, containment, relief well drilling, static kill and cementing, grants to the Gulf states, claims paid and federal costs. On June 16, BP announced an agreed package of measures, including the creation of a $20 billion escrow account to satisfy certain obligations arising from the oil and gas spill.
