[QUOTE=Alf;36121]The quote…
[I][B]“I’ve seen a lot of top drives with kellies on the floor. Of course that was back in the day when I rode my horse to the dock.”[/B][/I]
… wasn’t mine… but never mind.
In my roughnecking days we used kellies, and spinning chains and… and… … I like to think now that the technology we have is safer and better despite the fact it’s getting more complex.
Last time I saw a kelly in use was about 4 years ago on a Croatian land rig op. I think they must have got a job lot from somewhere, including the crews…!
if I remember correctly… the horse that’s mentioned in the quote … looked more like a donkey… but I could be wrong.[/QUOTE]
The charred cable tool rig that they used to film There Will Be Blood is sitting in Gary’s yard in McCamey, TX, he was using it up until they burned it, but he now has another one. Have you ever seen the well samples from a cable tool, big chunks compared to the fines of a PDC bit.
I read the article and it brings home the fact that there has only been one option to fix this well from day one: drilling a relief well. The political pressure on BP caused them to look for ways in which to attempt to combat the flow issues. They tried the ‘hats’, realising that oil capture was the main hope. These failed and the political pressure continued. Eventually, the idea that they may be able to pump down the C&K lines was considered possible. We all knew the risks involved. I feel the top kill has resulted in breaking down the formation (possibly through the Glass Plug in the 16" casing), and thereby creating a bigger leak.
I wonder if BP decided to do this on their own or if they were forced to try it, by a higher authority. Flow has increased as a result. BP would have been aware of the risks. They may have been forced to try and kill the well, even though we all know it could break down formations, thereby creating more flow areas.
Sometimes, political pressure backfires. There is no way to fix problems like this short term, even though Obama insists on and demands a solution. Easier said than done.
Check out the first few pages. Others also claim they saw similar things happening at the same time.[/QUOTE]
From these pictures I see dispersant hoses at work. The leak I saw coming out of the stack was further down about 10-15’ from the bottom& it wasn’t dispersant. It was oil Shooting straight out the side as hard as it was coming out of the riser after they cut the riser. Ther was also a small leak at the base of the stack.
[QUOTE=Alf;36128]No big surprises really.

Well, they were pretty much guaranteed to put holes in your casing! The more you pump, the bigger the holes.
Yet strangely (no that’s a lie…) none of this was made readily available to the public from their crisis centre over the last weeks.
It’s just yet another example of this puppet amusing the crowds, and occasionally it farts with a bit of info…

MMS, are fully involved and will be dictating action. They may have to answer for any decisions relating to additional flow caused by any surface activity sanctioned by them.
The only way to truly combat this well is through the relief well.

Please don’t do that. You should know by the design of the casing & the fact that the BHP migrated up due to all the things that were done to incite these events when there was zero political pressure involved, would have caused this by whatever means they would have used to shut in or pump on the well. Try another route because this one ends in the ditch. This was pandora’s box & from the day it was opened there was no closing it due to the initial design which you still refuse to acknowledge had any contribution to this disaster.
You never answered my question of assuming the company men / rig crew would have put their feet down & absolutely refused to go any further, what remediation would have had to be undertaken by BP to mitigate the condition caused by design defects ?

Do you have any evidence of this? It was supposed to be the Coast Guard in charge & yet Thad was on the air at 1500 Hours on the second day claiming they were pumping when in fact they had sut down to monitor some 16 hours before. We all remember that fiasco. So you mean to say BP didn’t use their stop work authority to not do something that could have made a bad situation worse ?
I’ve made 8 Youtube videos on this subject since May 24th. The latest has to do with Anglo - Iranian Oil Company, aka BP. Earlier ones dealt with images of gas jetting out … set to Buffalo Springfield, Godzilla set to Highway 61 and All Along the Watchtower. I made followups. I never had a thanks here yet for one video I made. Thanks guys.
I was suggesting a casing blowout a week ago … and I referred here to the BOP work thrust in our faces to watch as a mere “robot show” and diversion by "slight of hand."
Youtube has given me one strike for copyright violations. My videos are never featured, not even in the search engines by key word tags. Two more strikes for any reason any time and I am out. They kill real messengers. Most people “producing” videos on Youtube just copy and upload. Most writers just copy YT links. My video edits attempt to connect the dots and form missing BIG pictures.
We’re headed into a world of sheite. Anybody play chess here? Maybe we are only pawns in someone elses game. BP has been sacrificed in this game as perhaps a knight. God save the King/Queen. I set my course and see the BMF’s all around me now. I told you then we’re dealing with sociopathic gangs at the helm. A big storm is coming. Good luck, captains! Thanks for having discussions.

Don’t sweat it TBT. There are things I’m seeing now that as little as two months ago I would not have considered possible. I think this ongoing event is giving even the most trusting people cause to rethink their positions on the way business has been done. I will still stand by my earlier statements that not all CEOs are psychopaths. I will even give the operating officers of this disaster the benefit of the doubt (although it gets harder to every day ) that they did not intentionally do this damage. I will forever hold them accountable in that they should have known what their negligence could/ would eventually cause. They also have to be held accountable for their lack of action to correct their mistakes. To date as far as I have seen they have spent more money on advertising & trying to rehabilitate their public image than they have on paying the claims of those most affected by their negligence.

This is the NPD report from the Snorre incident in 2004 where the TLP platform nearly got blown up. I hope the investigation of the DH incidents is as detalied as this. I use this report often. If i feel we are doing something that may be in conflict with the rules I read this report again. I also recommend all foreign engineers to read it when they plan wells here in Norway. It is not “pretty” reading. It also shows how it could happen and that a lot of barriers failed as well as poor management involvment.

Or paid a few more weeks of day rate to complete the Macondo well properly.
[QUOTE=HellSD;36080]Looks to me like there is some kind of rectangular pattern evident in the right half of your second image. I don’t have a clue if it is the right scale to be a mud mat or if it is just an artifact of the image compression, but there’s definitely a rectangular crisscross there.[/QUOTE]
I’ve taken the same sea floor snapshot and applied an unsharp mask to increase contrast around visible and invisible edges in the image. I also scaled it by 200% (after edge enhancement) for easier viewing.
There are rectangular shapes visible in the right half of the image. However, these shapes are irregularly distributed. All of these shapes are also perfect rectangles aligned with the image’s pixel grid. These are characteristics of video compression artifacts rather than real features on the sea floor. Features in a mud mat (or any other grid-like structure) would be positioned more regularly and foreshortened by perspective rather than perfectly aligned to the pixel grid.

Just browsing through the table of contents of this report, why do I get the feeling that this report & the final report on Macondo #1 will have many similarities ?
MMS, must have approved the design.
We often drill wildcat wells worldwide expecting to allow for a certain amount of over-pressurized zones. When we meet a monster, we have to decide straight away how to control it. After eventually weighing up the mud and bringing the well under control further decisions are required as to the suitability of our well design. It may be that in a worst case scenario, we get full reservoir pressure at the WH. Our original design may not have anticipated such pressures. This may have been the dilemma facing BP when they initially hit the payzone!!!
At this point, the design is weaker than required. And yet, it is no different to all the exploration wells conducted around the world…which we have been permitted to drill. So, who is the authority in the US to say whether we carry on with the well? Is BP the authority? Surely, Gov’t agencies call the shots on what’s considered safe.
I suggest that BP applied for change of use from exploration to production, and a Gov’t authority approved it.
Regarding, the well design, I’ve worked on wells where we’ve discovered our casing design won’t meet the criteria required in the case of a well full of gas.
I have no idea what pressure was seen in the Macondo well WH prior to the blowout. We have seen the SPP reach 6000 psi on the logger’s charts. Other than that, I have no idea. All I’m suggesting is that it is quite possible that the Rupture disk may have remained intact. I’m also suggesting that no-one saw bullheading as an option immediately after the blowout. They opted for oil ‘capture’, knowing the probability of worsening the situation with regard to more flow to be a strong one.
When it was decided to give Bullheading a try one of two things happened: they either ruptured the disk or they pumped through an already ruptured disk at 1000 ft below the WH. As I said earlier, I feel it is quite possible that the top Kill may have exacerbated the situation by increasing the flow from other areas.
The great thing about this forum is that all possibilities are explored. This is a valid possibility.
Regarding the other issue, all I can say is that I would reccommend the crew shutting down when safety became an issue. The TP has to take the required action to stop proceedings when the Co Man fails to do so.
And, when a kind of agreement to continue was established, the crews should have been briefed on the possibilities that the well would flow. When the SW displacement took place as far as the BOP, failure to identify an anomaly in the SPP sealed the fate of the unfortunate crew. The well could still have been saved at this point. How we all wish someone was monitoring the displacement and interpreting the data.

If MMS aren’t involved and approving action being taken on the US shelf then we really are in trouble.

I would say it is, but I was wrong about the kelly that wasn’t a kelly & could be wrong about the pipe in the riser. So I won’t say that’s what it looks like to me.
Alcor said " failure to identify an anomaly in the SPP sealed the fate of the unfortunate crew"
It is not possible to tell which ‘anomaly’ or artifact on the strip chart you are referring to. Can you please identify that anomaly by time on the log? Are you referring to the SPP spike that began at 21:47?
IMO ‘failure to identify’ began at 21:30 when rig pumps were dead OFF and pit gain Continued. My belief is that they had earlier Noted AND Discounted pit gain as being Unimportant during an off-loading operation. This was a correct and reasonable judgment that I’m sure they had made many times before.
For an hour and a half, starting at 20:00, while displacing and off-loading, they Reasonably ignored pit gain. But then with rig pumps OFF at 21:30 (and pit gain Still Increasing!) they failed to make the Mental Shift required to place pit gain Back at the top of the Importance tree/list. They simply remained in ‘pit gain Not Important’ mode. A perfectly human nature kind of compartmentalization activity.
I have seen No log Evidence nor heard any testimony nor seen any time line to suggest that this is Not what happened. And further it would be almost impossible to believe that 5 or more bright, dedicated, and tremendously experienced men could simply Miss something like this. They correctly discounted pit gain while off-loading and did not reacquire it as crucially important when pumps stopped. They Did Not Miss the pit gain (which they certainly knew was one of the first signs of a blow out in progress). They discounted it.
