CM, are you talking about a view of inside the flexjoint, or of the riser after it was sheared? Post 2002 has an attachment that has one of the riser with the dual pipes in it. I am really trying to get my head around what/how there are two pipes inside the riser. One certainly is the DP, and the other is so similar I have to wonder if they didn’t shear the DP, then cycle the shear rams, and when they opened it up, slingshot the sheared DP up into the riser alongside the upper section. Some have suggested it is the lower production liner, but I cannot fathom several thou feet of casing going up that high in the riser. thoughts?
[QUOTE=Observer;35159]Exactly. The industry has got away with putting too much of its R and D budget into production and not enough into safe production. Ixtoc should have been a wakeup call that a lot more money needed to be spent to finding ways to contain or kill underwater blowouts quickly.
If the industry and regulators had put enough time and money into contingencies for deepwater blowouts, we’d all be debating why a semi-obscure platform known as Deeptwater Horizon burned and sank rather than discussing a four month long disaster that will have permanent consequences for the GOM and the people living near it.[/QUOTE]
An enormous amount of money is being spent on safety, just not in the right places. Companies evolve like governements, and the top is disconnected from the bottom, yet the bottom can bring the entire organization down.
Transocean’s financial committment to safety is unbelievable. As one small example: TOI sends sr supervisors on the rigs to a Chateau, north of Paris, for safety Leadership master class training. It’s a week of open minded discussion and exercise, by world class instructors. Upper management visits and gets right in the discussions. They treat you like a king. Are they really listening? Who knows…it’s probably more about how issues are presented…politics etc. Not money.
Then you go offshore: Adult daycare.
Everyone is brow beaten to submit a Start observation every day.
The weekly safety meetings are spent discussing nipped fingers and strained backs, whilst upstairs they are displacing a flowing well. Very 2 dimensional, is the safety mindset. The simple pyramid safety model looks only at at risk behaviours and numbers of incidents/behaviours. Severity is only really tracked with incidents, not at-risk behaviours. The model sucks imo.
People arn’t buying into the safty programs, because they are forced and brow beaten to participate.
[QUOTE=alvis;35080]Could someone comment on PLCGuy’s images of the inside of the riser? My untrained eye see drill pipe. But what’s that to the right?[/QUOTE]
It looks like its drill pipe inside the riser Alvis. Thanks for posting the pics PLC guy.
MichaelWSmith and rlanasa both have the same right and privilege to post their opinions on this forum as anyone else, even if they work for or lobby for BP. So please quit the snipping and playground behavior.

No problem, CM1. Thank YOU for all the good info and commentary you’ve posted.
I was snapping screenshots like crazy this morning during the shearing and riser removal operation. Just now had a chance to get back to sorting through them and found one more that might be of interest. I haven’t seen this view posted anywhere else so here it is: the other (top - away from flex joint) end of the kinked riser section. At this end I see only one pipe. Hmmm?

This is the way I interpret the pictures. The pipe has been smashed by the shears obviously while it was being cut. The force required to make this cut evidently caused the pipe to split in the seem where it is rolled into a tube when manufactured. When the burst rating of pipe is made it is based on one of two factors. As pipe is pressured up to the maximum pressure it will rupture in one of two areas. it will either rupture where the tool joint is joined to the tube, or the seem where it is rolled while being manufactured. The manufacturers of drill pipe will take a sample joint of pipe per so many joints in a lot. This pipe will purposely be pressued up until it ruptures. the average rupture pressure is the max bust pressure. This has been done on all makes & models of work string taking into account the type & grade of the steel. This is also done with tubing, casing, Etc. That is why it is SOP to never pressureup to more than 80% of burst pressure. The pipe is going to be approximately 1/3 the size of the riser. This is one third the size of the riser. I am glad you guys were on the ball on this thing. I was silent becdause I didn’t want to make any statements until I hopefully had a chance to see if the casing was lodged in the riser. If the casing had been lodged in the riser, it would have definitely had to remove all doubt from any BP apologist’s mind that BP had ordered casing that could not do its designed job.
Edit: A friend of mine designed those shears. His company has the exclusive patent on them. When I finish the job I am on I will call him & see if he can send me some pictures to post of some of the cuts they have made. His company has shears that are capable of cutting up to 60" drive pipe.
[QUOTE=alvis;35127]I think the lighter color is caused by the gas from the well mixing with the oil. You can see a tinge of white at the lip of the riser where the coloration starts. Would this be the liquid/gas interface?[/QUOTE]
Salutes Alvis and Observer. I myself am fascinated with methane, which goes from gas to solid, as an ice lattice, and then back to gas as solid/gas in two phases, dependent on the interplay of pressure and temperature. I speak as a man who listens and sees what is unspoken. If this event was a baseball game, they’d have a sportscaster. There never has been one. No soundtrack. Many find it boring in a day of ADDH.
This event is quite important to me and so again I offer you a video that expresses where I’m at … with methane and methane hydrate. If nothing else, enjoy the music. I don’t come here to gain fans for youtube, but I speak through youtube. Thanks for allowing me to speak and be heard. My point in this video is to show visual evidence of methane releases that puzzle me. No need to reply here. Trust that I’m pulling for every one of you. I do my best as crew.
tic toc…so…the cap has been in place for a good while now…
In live feeds, we are currently seeing, on a few cams, a good flow emerging from underneath the bottom of the cap AND, on one cam, a high velocity flow emerging from one of the relief ports on top of the cap…
based on flow prior to the cap being placed, it wouldn’t appear they’re suctioning off any oil to the surface…
BP only said that from THIS point, the relief ports would be slowly closed…but NO time frame…
any thoughts…?
and…IF hydrates had formed and were blocking the flow, wouldn’t it be likely that they also would have blocked that top port that we can see the high velocity coming from…?
and…IF hydrates had formed, would we see them remove the cap pretty quickly OR would it be possible to remedy that situation with the cap in place…?

I agree with your thoughts on the 7" casing going up like that. One problem it would have is going through the crossover. I do believe that it is possible that the 9 5/8" or the crossover could have ruptured while they were attempting to break circulation before pumping the cement job & could have possibly led to the cement being displaced completely away from the formation where it was supposed to cover, but even at that, I have trouble believing casing could have been displaced into the BOPs. It is possible though & hopefully one day, the truth will be unveiled.
Skandi 2 just went to work - appears to be only ROV actively working…not sure what or where…might just be preening…
no no…looks like it’s rigging up some tool/probe to it’s arm…readying for action…
Skandi Neptune’s ROVs are usually tasked with managing subsurface dispersant injection.
So far, major work has been the domain of Enterprise and Ocean Intervention, with some help from Viking Poseidon. All of these feeds are quiet right now.
Looks like Viking Poseidon one and DE 2 are both working again.
Shift change at ground zero? Lots of activity started just a few minutes ago.
Enterprise 2 just moved itself to watch the top of the stack.
BOP Deep C ROV #2 is involved in ‘dispersant hose relocation.’
Poseidon is working with the other LMRP cap.
Ocean Intervention 2 started working with a dispersant hose but is now in zero-visibility conditions.
[QUOTE=CPTdrillersails;35136]OK, I don’t want to be critical, but I’ve seen this flawed theory on the oil drum and want to debunk it now. You are confusing what the mass is (force = mass * acceleration). The mass is not the mass in the column, it is the mass leaving the column. In other words, to find the force needed to stop the flow, you take the mass being ejected times its velocity and divide by the time you will take to stop it. This force is negligible compared to the reservoir pressure.[/QUOTE]
Thanks CPdrillersails - a common misconception. The science of equilibrium v. the science of a change in equilibrium. What you say is right in terms of a continually exiting jet. However it does not apply when you want to change the equilibrium and stop the jet and all the fluid in the column altogether. In terms of acceleration, this occurs wherever there is a change of velocity. In turbofans it is at each stage of compressions/combustion. If we assume that the density of the oil from the dome to the BOP is constant, acceleration occurs as it leaves the dome and at each stage of the change in diameter of the casing. Larger diameter, slower velocity, force on the column of oil is actually downwards. f=ma=m(v-u)/t=(mv-mu)/t, impulse f x t = mv-mu. If your final speed v is 0 then you have to provide an impulse to overcome all mass that is moving mu. I well understand that my velocities are all in a mess because I did not allow for a far larger diameter in the bulk of the well bore. However, it is all irrelevant. Now they have a cap on and hopefully they can capture the bulk of the oil. Can industry experts tell us what the plan is when a hurricane occurs and the collection ship lets go of the vertical riser. Kent was thin on this.
Cool link to a blog where the kid has all the available ROV screens on one page:

People don’t buy into a safety program because they that ultimately, once you get past the propaganda it is BS. They turn in their “START” cards which are not mandatory but required [go figure that one out] just to keep the powers at be from reporting they didn’t turn one in. If they turn in too many safety cards with legitimate complaints they get either browbeat into not doing any more or otherwise discouraged. The entire safety program was designed by attorneys to lower worker injury claims which hit TOI along with every other company in the pocketbook. If workers couldn’t sue there would be no “start cards” and a lot of lawyers would be unemployed.
If BP and TOI truly have a serious safety program which is mandated for EVERYONE where are the task risk assessment, “start” and “cake” cards from the tool pusher, OIM, drilling superintendent and BP company man for the day the Horizon exploded, killing 11 men and creating a world class environmental disaster? Why didn’t any of these people use the safety programs’ ‘time out for safety’ when these decisions were being made pre-tower? Were they afraid of the consequences of shutting a job down or did they think the ‘safety program’ just applied to the lower echelon that might hurt their back or have a ‘dropped object’ land on them? Just asking.
Anyone else scene these numbers?
[I]“The reservoir pressure is 9,000 psi, and the pressure of oil coming through the BOP is 3,500 psi, he said. The collected oil and gas will go into a smaller pipe, which could increase back pressure and cause oil to leak out around the seal.”[/I]

It seems you are quite a reservoir of venom – ready to “blow out” into an uncontrolled spill of hatred – at anyone who refuses to toe-the-line and leap onto your “lynch-BP-now!” bandwagon.

So, in your opinion, then, the fact that thousands of wells have been safely drilled since the Ixtoc disaster is a result of mere luck on the part of the oil industry?
