Re: Freezing leaking oil in Gulf of Mexico
The problem with this is that they have a weak point where the riser is kinked and the riser itself has a relatively low burst pressure. They need to block the leak within the blowout preventer (BOP) which has a much higher burst pressure.
Here's how I would do it:
I would cut a rectangular section out of the top of the riser near the kink, removing a curved rectangle about half the diameter of the riser and at least ten feet long.
At the far end of this notch I would insert a flat plate. This gives us something to push against.
On this pushing plate I would mount a hydraulic ram.
I would push a chain mail screen deep into the riser, as close as possible to the kink. The chain mail links would be just the right size to catch golf balls.
I would then do a junk shot with golf balls, filling the riser and the top of the BOP with golf balls.
Then I would shoot in shredded tires which would create a full blockage within the BOP.
Then comes the mud, followed by the cement.

Re: Freezing leaking oil in Gulf of Mexico
Hi Gary, I have not really studied this, and I am sure they are not going to employ a sheep ****ger from New Zealand.
The point I was really trying to put across was that, those who are trying to fix the problem, are from the same peer group in the same industry, thus are likely to be thinking in a similar manor, in many cases, when solutions are required, it is best to employ some one left field, out side of the peer group education stream

Re: Freezing leaking oil in Gulf of Mexico
The problem with having the oil industry's leading experts working on this is that experts do things strictly by the book.
If they do it by the book and it doesn't work out, they did the best they could.
If they resort to unconventional methods and it doesn't work out, they are the reckless idiots who screwed the pooch.
Experts are not innovators and innovators are not experts. This is as it should be for most situations, but sometimes they need someone who thinks outside the box.
Or perhaps a collaboration is needed, with an innovator coming up with ideas outside the box and an expert who makes those ideas fit within the box... so the pooch doesn't get screwed.Last edited by Gary; 02-06-2010 at 07:28 AM.

Re: Freezing leaking oil in Gulf of Mexico
If they had the techo stuff to cut off the bend bit, why can't they crimp off the pipe.
Where is the drilling company in all this. The guys that screwed up in the first place, killing rig workers. They are conspicuous by there absence.
Then we have Prezi-Obama getting his shorts in a bunch.

Re: Freezing leaking oil in Gulf of Mexico
This would be comical if it weren't so damaging. These idiots jammed their saw in an effort to cut off the riser a few inches above a flange so they could install a makeshift cap that leaks like a sieve. I wonder if it occurred to them to just unbolt the flange and connect a real valve above it.

Re: Freezing leaking oil in Gulf of Mexico
Hi Gary.
I am not suggesting for a moment that the situation is comical, this would have to be the worst man-made enviromental disaster in my memory since Bikini Atoll and Arizona testing, or lately the Kuwait well head burning after the desert storm. Here we bore the brunt of the ozone hole which effectively fried everyone real quick.
In my mind I cannot help feeling that something could be done real quick to resolve the leak, but they still want to maintain the well head for the oil downstream. So as to satisfy the biggest fuel market in the world, in the USA. The whole thing is money driven by "Wall Street ". those people again.

Re: Freezing leaking oil in Gulf of Mexico
couldn't agree more, what is starting to annoy me is the words being used out of the whitehouse, they are now saying this disaster is as bad as 9/11 and are blaming the Brittish, i think that is a slap in the face for everyone of the 3,000 familys who lost a loved one to a terrorist attack!! the disaster in the gulf is a bad 1, but to lay the blame at the feet of the Brittish is not on, yes it may be a Brittish company, but all the work force and equipment used is american, it all comes down to the thirst for iol in that part of the world

Re: Freezing leaking oil in Gulf of Mexico
Hey guys! interesting to read your view / solutions of the mess in the gulf ...I read that Russia has said they closed off several out of control wells by using a small nuke .!! the world sure as hell has enuf of them!!!
but it really seems that it should be straight forward to pinch the pipe closed and limit the flow to a relative trickle.........if they can put a saw down there to cut it off ... why not a clamp?? dddon from MN

Re: Freezing leaking oil in Gulf of Mexico
I've been watching this story closely and here are a few bits and pieces I have garnered along the way:
There are any number of ways to plug the flow. That’s the easy part. The oil industry routinely uses an inflatable device called a packer. The question is not how to plug it. The question is where to plug it… and if it should be plugged.
The pressure at any given point is the source (oil reservoir) pressure minus the pressure to lift the oil minus pressure drops through restrictions along the way. When you plug the flow, the pressure drops through the restrictions are gradually eliminated (think pressure equalization) and the pressure upstream from the plug ends up being source minus liquid lift. If methane bubbles its way up displacing the liquid, then it is just source pressure. Estimates start at 9000 psi and go up to about 30,000 psi. That’s the problem.
If the riser had been plugged while it was lying on the sea floor, given its relatively low burst pressure (1400 psi + 2400 psi water pressure on the outside = 3800 psi), even if it were in pristine condition, it probably would have burst. With it bent and cracked, there is no doubt about it.
I have heard that the BOP, which is designed to handle very heavy pressures, is showing signs of stress cracks, so plugging it at the top, or anywhere within, may in fact burst it.
We can move the plug point to the wellhead under the BOP, but here comes the really bad news:
The well is made up of concentric concrete casings. The inner well casing/tube itself has a concrete plug at the bottom. It is strongly suspected that the oil is coming up between the casings and leaking between the top of the inner casing and the heavy concrete slab which is holding it all down.
If sufficient pressure is allowed to build up under that top slab, the entire well structure could be launched, leaving a gushing crater that makes the current leak look like a dripping faucet by comparison. Or as one oil field worker put it, “You ain’t seen nothin yet”.
The safest bet at this point may be to produce as much oil as possible to hold down the wellhead pressures and wait for the relief wells… and this seems to be what they are doing.
Once they get all of their production piping in place and working, I would hope their next step would be to entomb it all under a mountain of concrete, to hold down that top slab while they wait for the relief wells.Last edited by Gary; 15-06-2010 at 06:45 PM.

Re: Freezing leaking oil in Gulf of Mexico
I saw someone quoted the pressure at the sea floor is about 2,500 PSI. Has anyone heard what the pressure along the length of the well casing is?
There's a formula, hagen-poisele or something like that, if you know the delta pressure and the diameter and the length and here's the kicker: the viscosity, then you can calculate the flow.
Did they even get a clean cut of the leaking pipe?

Re: Freezing leaking oil in Gulf of Mexico
i have a solution. sack all higher management for oil companies and throw them in jail as all they care about is money and bonuses. too many times i have seen incidents kept quiet so managment could get there bonuse. Also stop the yanks from drilling and the british.

Re: Freezing leaking oil in Gulf of Mexico
As I see it, the problem is the methane. A column of oil several miles high can hold down the reservoir pressure, but a column of methane will deliver full pressure up to the wellhead, through the BOP and up to the drilling rig.
I would install a parallel loop around the BOP. The loop would open with a pressure relief valve to reduce wellhead pressure, sending the oil/methane mixture through a methane separator (think oil separator). The separated oil would loop up to the top of the BOP, while the separated methane would be blown off, burnt off, produced... anything but deliver it to the drilling rig to cause explosions.Last edited by Gary; 20-06-2010 at 09:10 PM.

this tragedy claimed lives,nobody i know thank god,but it will be sorted guess a lot of money and time.but this find a scapegoat fast nail him to the mast ,gun ho yanks in full flow,bopal,friendly fire, lockerbie,four mile island,niger delta,remember the planes that bombed tripoli left our shores,not to mention screw ups on a global scale every week.dont get me wrong i love americans they push the technical boundarys i lived thru man on the moon,there help in our defense in 2 world wars men laying there lives on the line and never getting back,been to arllington cemetary and the beaches at normandy thanks many thanks,but hey guys an eye 4 an eye makes 2 guys blind ,get the prob sorted THEN get the nails and the cross in place.sorry if i upset anyone but i think your innocent till proven gujlty.

Re: Freezing leaking oil in Gulf of Mexico
I don't know of anyone who talks like that or even thinks like that. You've been listening to the propaganda machine... your's, ours, or maybe both.
Politicians are the lowest form of life and the media is not far behind. They don't care who died or how to resolve the problem. They just want to know who to blame so they know whose pockets they can pick.
If we ignore them... maybe they will crawl back under their rocks.Last edited by Gary; 21-06-2010 at 12:14 AM.

This should be the last drilling licence to be issued to BP. Their chief exec's performance is abysmal. He comes across as arrogant toff.
