Top killer: BP plans to pump mud at high-pressure from the platform of the vessel Q4000 into its crippled well in a bid to squelch the month-old Gulf spill.

But BP's "top kill" method to stanch the spill could also break it wide open.
BP is preparing to launch a procedure as early as Sunday to clog the flow of oil and gas from the month-old Deepwater Horizon spill in the Gulf of Mexico. But the proposed "top kill" method is untested at the 5,000-foot depth of the spill, and could easily join the growing list of fixes thwarted by the spill's punishingly remote environment. It is also the most invasive maneuver attempted to date, and could rupture the leaking well and actually accelerate the flow of crude.
The potential environmental impact of the spewing oil picked up gravity this week when observers saw the first evidence of oil entering the loop-flow current that washes out of the Gulf and up the eastern side of the Florida panhandle. The oil threatens to foul Florida's sensitive coral reefs and its tourism economy by the end of May.
Oil containment operations simultaneously gained ground last week as BP installed a tube in the crippled mile-long riser that once linked the Deepwater Horizon rig to its seafloor wellhead. By Wednesday, the ad-hoc Riser Insertion Tube Tool was sucking 3,000 barrels of oil per day into the holding tank of a drilling vessel, cutting releases to the sea by roughly half; the vessel is also flaring off about 14 million cubic feet of captured natural gas per day.
BP's riser insertion operation marks its first real technology success after a string of high-profile failures. One early effort to suck up spilling crude--a 100-ton steel box lowered over the wellhead--jammed within hours with a frozen slurry of natural gas and seawater. This fiasco followed weeks of fruitless attempts to stimulate the blowout preventer, or BOP, that sits atop BP's crippled wellhead. Ongoing Congressional investigations last week highlighted design limitations and potential maintenance lapses involving the equipment, which the offshore industry hitherto regarded as a "fail-safe" defense against deepwater spills.
The BOP's possible design flaws may help explain why it could not stop the flow of oil and gas and save the rig after it lost control of its 18,000-foot well on April 20. Steve Newman, president and CEO of Transocean, Deepwater Horizon's owner-operator, told a Senate hearing Tuesday that the BOP's "dead man" mechanisms failed to trigger its rams to pinch off or sheer the drill pipe because the automatic activation mechanisms respond to separation of the BOP from the riser or rig--only the latter occurred, and not until two days after the accident.
Maintenance issues, meanwhile, may also explain the failure of the BOP. A loose fitting on a hydraulic line may have limited the force of the BOP's rams and crimpers. And shipboard testing of a control panel recovered from the BOP revealed a low battery.
The top kill procedure, if it works, will stanch the flow of oil and ultimately allow workers to cap off the well with two relief wells-but these caps won't be ready for several months. It will use the BOP's three-inch-diameter choke and kill lines, which open into the space between the well's casing and the drill pipe that runs up the riser. The lines are being cut and spliced into hoses connected to the Q4000, a vessel on the surface, whose 30,000-horsepower pumps will drive a dense mix of clay and other substances called kill mud into the lines. If the mud cannot stop the flow of oil, BP says it will be ready with a "junk shot," in which a mix of materials from shredded rubber to golf balls are pushed into the lines to further gum up the flow paths through the BOP.
Microbes may have eaten away at BP's oil in deep water; now the marshland needs help.
Safety upgrades are critical but could mean higher prices for oil and gas.
The disaster exposes overreliance on blowout preventers that has been long disparaged by insiders.
We need more regulators....like the high paid bureaucrats that we pay to watch porn at the office. With deep water drilling being so new and specialized, where inside the beltway will Obama find these regulators? Perhaps among his old Chicago neighborhood organizer mob.
Where is the East side of the Florida Panhandle? It's not water. It's called North Florida. The Panhandle is the non-peninsula portion of Florida that lies below SE Alabama and SW Georgia.
Re: We need more regulators...
This is worth a try ... they'd probably have to stuff a couple hundred regulators into that pipe to plug it up I'd guess.
Put the Coast Guard in charge of offshore, not some Dept of Interior folks.
The 3000 barrels per day being siphoned off is roughly half of BP's stated estimate of the size of the leak (5000 barrels per day). But there is good reason to believe that the actual size of the leak is much larger.
Has anyone considered using a series of large explosions (set off in unison) surrounding the leak, but have these detonations happen under the sea floor so the ground actually compresses and chokes off the flow of oil?
Basically -
Drill 6 to 8 holes around the perimeter of the leak source, but deep enough and close enough to the original well pipe to cause it to collapse or bend sharply when the detonation happens.
Envision - Bending a soda straw by kinking it but use a heck of a lot of C4 to do it.
IMHO, great idea for a movie. Not so great for reality. Explosive events are hard to design and predict the outcome.
BP isn't the one to blame. Do you wanna know who is to blame? It's you. It's me. It's all of us. Everytime we take the SUV to the corner store for Funnyuns. Everytime you throw away another plastic bag. Everytime you put oil on your farking toast. You are using up this dwindling resource. And, until we wean ourselves off, we are just going to keep seeing more of these disasters as companies use more extreme measures to suck our Mother Earth dry.
Nature is to blame because oil is a naturally occurring resource.
The sun is to blame because with out the sun, there would be no life, and so no oil.
Libs are to blame because they haven't thought of a workable alternative yet. Plus, they stop nuclear plants from being built for the last 30 years.
Obama is to blame because he accepts money from all those evil companies.
My dog is innocent. She is a good dog.
U.G.
What are you suggesting here? Do you have a plan we can all use?
Buy and ride motorcycles. Press the gov't to give tax incentives to motorcyclists (and bicycles, and public transit users, etc).
We are to blame has a good point. Even though we regard us humans as the superior being, and not even not related to the animal world, we do exactly as they do in that we exploit our environment to the maximum to our advantage. We say that nature is in balance and we just screw it up, but in reality there is no mutual agreement between animals and the earth in maintaining a balance in their existence and the world around them. There is just an oscillation between feast and famine where predator and prey never get completely annihilated. We are currently on the feast side of the equation, and all the concern is that were swiftly falling toward the famine side of the equation. When oil goes, so will we. There is a finite amount of oil and other natural resources that will eventually get used up. We can do what we can to delay the process, but its still just a delay. Hopefully an energy source of equivalent replacement can be found in time. I’m sure there are other alternatives, but they are not going to be perused until they have to be. If using solar cells were cheaper to power our homes that what is being used now, that’s what we would be using. Hydrocarbons are the raw material for a huge array of items. As they become less abundant the more higher risk methods of extraction has to be attempted. In this case we lost, somebody actually messed up somewhere. Maybe it was sabotage, or maybe is was just a worker who came to work sick because they could not afford to get fired and overlooked a critical procedure. Maybe it was a general company wide conspiracy in trying to get away with something on the cheap, and this time it did not work. Yes, we the consumer, are the reason why oil is drilled in the first place and it is we the consumer who should rightfully pay for the cost and assume fundamental responsibility. Don’t expect accidents never to happen. You can replace the word ‘oil’ for all the other thousands of things we exploit from mother nature that cause major disasters to occur. Don’t expect the use of hydrocarbons to ever go down very soon. I agree some outside source that would financially benefit for stopping the leak should have taken over the operation. Big business who’s actions result in a disaster and are then expected to fix the problem seem to have a tendency to take the cheapest route, which in this case would be to just do nothing and move on to the next drill site and let this hole just drain dry. I don’t expect us to find that using any alternative resources is going to end up being any less of an exploitation on the earth and causing some other kind of earth-depleting problem that we know not about yet that have now with using Hydrocarbons.
Sink a 40,000 ton flat-bottomed warship on top of it. Cement around the edges when settled.
What about sinking a big empty hull of a ship upside down on it with multiple heated pipe attachments on the bottom of the ship? Float it out to the area. Guide it down with cables from four other big ships as it sinks.
Drop down a upside down 40,000 ton warship over the oil leak? Would it not need to be a tanker ship that could hold the 100 million gallons or so of oil coming out. And what about huge amount of natual gas getting out also? How long will it take to set this up? By tomorrow, or a year from now? Where is the ship your talking about? Who is going to cut out the hull, and who's going to take resposibility in doing all this? No offense intended, but where did you get the idea this is simple? How many times has this idea already been done? If it is simple when will you have it ready? I'm guessing this might be the first deep water oil disaster that has occured, at least that the public knows about. Let BP do their stuff. They won't do any better or worse than anyone else. The damage has already been done...Its now just a learning experiance.
Ignite the fuel at a controlled depth
Clean the spill by deep sea burning ---- Seeing pictures of deep sea volcanoes such as on National Geographic’s web site suggests that aerating the area around the oil head and then igniting the aerated crude with a barrage of the same igniter sticks they use to fire the space shuttle rockets would be no more harmful than a deep sea volcano. Aeration and ignition should probably be at fixed distances above the actual broken well head.
Throwing this much burnt material into the deap sea should be no more dangerous than any of the deep sea volcanoes.
Re: controlled underwater burn
.
I agree, it's my first idea published in the article linked in my comment above
.
Thermite shaped charges as cylinders around a cable threaded into the wellhead and then ignited will turn the surrounding sand and the metal of the drill casing into a giant glass cork with high carbon and high iron content.
A giant TERMPERED GLASS BUBBLE of military grade strength at the crushing and cold depths of the BP well will be the result of a string of thermite charges ignited in the drill column.
BP does not want to seal the well, they will sacrifice ANYTHING and EVERYTHING to keep this well flowing ... why?
How are you going to get this in the wellbore? There is a riser attached to a BOP, attached to a wellhead. Inside the well is drill pipe. When you remove the riser or BOP, what will the flow rate be then? How much worse will the leak rate be at that point?
Guest (lordtzer0)
I thought about thermite as well. However there's a possibility the oxygen taken out of the water by that much will create a bubble of hydrogen gas. If they are still doing a burnoff on the surface at the time . . . well you see the possible problem with that. A simple implosion is safer and simpler.
You are absolutly correct the US NAVY has the resources to design and place a shaped charge around the outside and colapse the structure like superman. So the question is if we have the capability why has it not been done. Well BP is currently extracting oil and they can not extract oil if they distry the well head but stopping the leak is not BP's priority they have time and money invested in that well and they are doing everthing to save it not stop the flow of oil. So why has Obamy not called upon the US NAVY to take care of the problem????
I would insert a high pressure gas bladder into the pipe and inflate it to plug the pipe and stop the flow of hydrocarbons from the floor of the Gulf until a more permanent solution can be put in place. A couple of industries off hand that could have adaptable equipment and know how for the task would include automotive airbags, NASA air bag landing systems, tire and rubber production, etc. Or how about a oil pipe inspection pig adapted to plug and stop the leak.
Wouldn't the bladder seal better if there was a heavy liquid filling the bladder? Oil for example. or the sludge mix they intend to try to use to plug the pipe?
So you seal off the end of the riser... What happens when the pressure builds up on the riser and bursts or breaks near the wellhead. What will the leak rate be then - 5 times as much?
Improper Handling approach to BP Pipeline Leak
We, as a Nation might have missed an important mark in strategically handling and bringing the whole leak issue to an end.
Leaving the matter into complete hands of
BP Corporation had been a colossal error,
administratively and politically. The nation,
realizing,critical importance of the problem,
would had rallied and despatched team of experts
to ensure timely and unescalated resolution
of the technical problem,and thereafter,confront
BP Corporation for equitable reparations and damages.
A pipeline leak and the set up design cannot
fail to have terminal shut down nozzles. I keep
wondering why BP has not acted to shut down in
totality its terminal systems to afford examination, exploration and deployment
of a befitting technical solution.
Any technical problem that is inappropriately
managed generates inappropriate permannent solution. Our technical experts must push
outside BP COrporation and tackle the leak
matter with every expedition.
The financial bounties comes after repairs.
In my business we use hydraulic clamps or jaws to squeeze and seal pipes filled with refrigerant. It would not be difficult to design and build, quickly, a set of jaws that could crush and cold weld a 21-inch diameter tube having 1-inch thick walls. The process would guarantee no leakage.
Will the riser upstream of the resultant "pinched" section hold or fail? Will the leak rate increase as a result? There is also drill pipe inside the riser.
The riser upstream of the tube will not be affected and it could be cut off above the "pinched area" if desiarable. The clamping force of the jaws would be suffient to smash and cold weld the 21-inch diameter, 1-inch thick wall tube and the drill pipe that is inside the riser pipe. The jaws would be of very high-strength steel and hardened. The hydraulic fluid pressure would have to be no more than the pressure that they produced in the attempt to force the heavy mud down the well. They can easily obtain millions of pounds of force to crush the tubes and fully cut off the flow of oil. I'm attempting now to find a way to get this message to a responsible party.

Better an oil spill than sitting in the dark and freezing. Before you start in on the environment, I'll take you seriously when you start bemoaning volcanic eruptions as much as you do, coal, CO2 and petroleum.
During WWII, mow many barrels of oil were released into the Gulf of Mexico (worldwide?) due to tankers sinking? I know I've dived (scuba) at least 6 torpedoed tankers. I suspect many more were lost. Funny, how the world didn't end then, eh?
A hugh baloon attched to tubing of oil flow tube blowout, with large tubing attached leading to the waters surface to vessels atop. Attach to top vessels first, then to bolwout. VESSELS, carry to processing area and save oil as well as wild life and the economy. For the Love of Christ, don't destry this Country.
RLAH
Step 1: 20 ton concrete blocks with heavy steel hawser threaded through each dropped either side of the leak.
Step 2: Attach two of the hawsers ends to a magnetic cap shaped to fit the pipe.
Step 3: Attach the other ends of the hawsers to large winches on board suitable vessels.
Step 3: Synchronize the winches.
Step 4: Pull the plug downwards until it clamps onto the pipe.
Step 5: lower a 1 mile pipe to connect to the plug via a custom gate valve.
Step 6: Begin syphoning off the oil to ease the flow pressure.
Step 7: Bolt or weld the plug to the pipe once the water has cleared sufficiently for the RUVs to see what they're doing.
Step 1: Lower 20' long half section of 1" thick steel pipe with sets of adjustable steel straps in incremental distances from the ends towards the centre.
Step 2: Fit section underneath leaking pipe 10' from hole.
Step 3: Slide section along damaged pipe until underneath leak.
Step 4: Swivel half section using hawsers & winches from surface vessel until it sits over leak.
Step 5: Tighten straps, starting with the ends.
Place an extremely large cement collar over end of pipe . { use models to estimate size} . have extremely large tubing to attach in segments in order to bring oil to surface . The trick being to keep everything extra large, with the bottom piece heavy , to keep it in place .And up she comes .
It seems that what BP now has in place is a preliminary answer. The cap recovers about half of the leakage, according to reports. The rest of the oil leaks through stub-ins that are placed around the pipe to bleed off methane. This is to prevent freezing as the methane cools on expansion. It would seem that electric heaters could be placed around the pipe (if any will work at 5000 foot depths). The heaters would remove the necessity of the stub-ins, which could then be capped. Heaters of this sort are in common use in the refining industry for highly viscous fluids, but whether they would work at depths which are beyond their design specifications is the question. Perhaps some could be specially designed that could be put in place quite a bit earlier than the relief well.
Lines of industrial pipeline heaters from various sources, for any interested, are at the following link:

Deep Water Piledriving Technology
Error in reporting-- the Big Bell and Top Hat were salvage operations at the end of the fallen riser. It wasn't until May 20 that the first video of the BOP and wellhead were released!!
Of course, before you can come up with solutions to a problem a person must know the full extent of the damage. How can you do that when all you get from BP and the government is lies? For instance, the wellhead and bore hole are fractured deep into the bore hole. If you seal the top of the BOP the oil will simply flow out of the burst pipe below it. BP and our government have been covering-up that fact.
The report of another larger wellhead leak and cracks in the sea floor is also kept hidden from the public. The US will not even send their own submersible down to survey the other oil well leaks in the sea floor; some are 8 miles from the blown-out well that BP is stalling on.
BP and our government are lying to the American people about the full extent of the damage. It is as if BP and the government have their own plans for genocide and World Government and the oil spill is an attack against the American People.
The degree of stupidity, propaganda and Treason is amazing and they have convinced everyone there is nothing anyone can do to stop the oil flow; that is unadulterated BS!
The oil flow could have been stopped a month ago using known deep water pile driving technology. A simple solution is to lower a 4’ pipe over the BOP and the bore hole and than drive the pile 200 feet into the sea floor permanently sealing off all of the oil flow. The pipe can then be sealed with concrete and cut off far below the water line. It would take 83 sections of welded 60’ pipe and 80 valves to get to 5,000 feet in depth and the same pile could be used to seal multiple leaks. This is how all of the oil leaks in the Gulf will be stopped next year or 10 years from now.
Please do not whine that if BP and the government could stop the flow of oil, they would; you are just buying into the propaganda and lies! This is an ecological and economic genocide and Americans are so brainwashed and propagandized they do not realize it!
It is obvious after examining the facts that Big Oil, World Banksters and our government are on their own itinerary of implementing world governance and destroying our Democracy and Independence; all for our own good, of course!
Re: Deep Water Piledriving Technology
One wonders how a spill of this magnitude would be handled if it was in the North Sea, where it would impact the coast of Europe.
Based on your comment, “...It wasn't until May 20 that the first video of the BOP and wellhead were released!! ...” do you have information on what type of BOP (singular) was installed. You imply that there was only one, and earlier reports only mentioned an annular BOP.
An annular type costs considerably less. If a well head is designed properly there should be both types (annular and ram type). There is agreement in what you say about the paucity of information being provided by the government and BP. Full disclosure should have provided schematics (piping drawings) of the well head. It seems obvious that, since this sort of complete disclosure is missing, BP was in violation of safety requirements for well head design at these depths. Reports are surfacing that BP has had 100’s of safety violations regarding the design of its oil exploration operations, whereas companies like Chevron, Shell and others in the area have only been cited in low double and single digits.’
Regulations also state that, for spills from oil operations, there is a penalty of $4500 per barrel. This should be assessed, and that would put BP out of business. That is not a case of “too big to fail”, because, just as with the current debacle in the banking industry, BP still has assets that could be taken over and managed by competent oil industry executives, thereby removing those who are willing to cut corners and buy the silence of government officials.
Re: Deep Water Piledriving Technology
Where did you find out that the well head is fractured? I would like some more "confirmed" technical information on the situation or problems encountered.
Thanks,

Hi, my name is Kalashnikov, just the same as of famous AK-47 submachine gun inventor. I know how to stop oil spill easily. This know-how technology is simple and cheap as submachine gun.
I sent my proposals to some e-addresses but got no reply. Either they do not care or do not believe. Every minute counts and shows/proofs their helplessness. Who do you advise to adress?
Capping the Spill, A Calculated Solution
ID pipe = 24”
Sq in ID pipe = pi*(24^2)4 = 452.16 sq in
Crude press = 70,000 psi
Weight of steel = .283 lb/cu in
LENGTH OF STEEL ROUND BAR, 1ST INSERTION, TO COUNTERACT PRESSURE
Given: bar 1” less than pipe ID = 23” (less than required to insure full insertion)
Area of round bar end = pi * (23^2)/4 = 415.265 sq in
LENGTH OF ROUND BAR TO COUNTERACT PRESSURE
Total force on round bar end = 70,000 #/sq in * 415.265 sq in = 29,068,550 lb
1” length of round bar weight = .283 lb/cu in * 415.265 sq in = 117.519995 lb/in
To counteract 70,000 lb/sq in requires 70,000 lb/sq in / 117.519996 lb/in = 596 in =
596 in / 12 in / ft = 50 feet of round bar 23” in dia.
Note: to simplify, buoyancy was not factored in the calculations
Once the first run of round bar is inserted there will be a large manageable pressure drop at the top of the first run of round bar. The bar end should be further modified from a square cut-off to a pointed or rounded end to counteract any unknown distortions in the well pipe.
Since pipe diameters for the full length of the well run have not been published, this is a preliminary idea on a solution that could be refined by those with full well design information. The steel employed should be capable of remaining intact for the foreseeable future.
A further note: If insanity can truly be defined, those who suggest nuclear devices are insane! Suppose, instead of sealing the leak, more and larger fissures are created, and the heat of the detonation ignites the huge quantity of escaping oil.
In the last paragraph, on the first page, the artical mentions relief wells. Relief wells take months to drill. This is the cure that works.
At the Ixtoc spill, thirty yrs ago, there was a pressure kick that destroyed the BOP; caused a fire and spill. After many months, relief wells fixed the leak. We have not improved the safety of rigs in the three decades since.
They hope to stop this one as early as August. It is a safe bet that a better fix will be found for the next one.
It was know that pipe crushing Blowout Protectors may not work on the heavier pipe used on deep water wells. But it seems none were ever tested. This seems to be a needed first step.
As long as they had a pipe down the well, why didn't they pump Liquid Nitrogen down it. Would this not stop the oil flow until something better could be put in place?
Manufacturing in the United States is in trouble. That's bad news not just for the country's economy but for the future of innovation.

in the next ten days up to 30,000,000 of more gallons of oil will be spilled in the ocean!
.
and... 30,000,000 more gallons of oil spilled, means add 30,000,000+ gallons of TOXIC dispersant to (try to) absorb them!
.
solve the problem in HOURS and NOT weeks!

Re: >>> STOP the oil spill NOW >>>
Why couldn't they use DMSO instead of hot water so that ice couldn.t form using the tophat?
DMSO ( Di Methyl Sulfoxide) @ 100% concentration freeze point is 65°F. But at 70% with 30% demineralized water is -130°F. It seems to me that a solution of DMSO could have worked.
Have A Sparkling Day!

I doubt there is a conspiracy, oil prices are down $20 since the spill along with BP's stock. This will cripple the company for years to come.

Re: >>> STOP the oil spill NOW >>>
I've already sent BP everything they need to do the job. It's up to them if they don't wish to listen. It's simple. Implode the well. 2 days after I sent that suggestion there was an ex-submarine officer on the news saying the same thing. It's been done quite a few times, including being done with nukes by the Russians, though I agree with him that conventional explosive will do the job just fine, and it won't radiate the oil leaving it unusable for sometime. I also suggested to them that instead of dispersant they use an oil eating micro organism known as archaea. Archaea Solutions has been using them for years to clean the lagoons in pig and chicken farms, as well as decontaminating oil and fuel spills on airbase runways. The only questions would be is there enough supply to meet this kind of demand. The Gulf is no runway or sluice lagoon. There may only be enough for wetlands recovery unless production can be ramped up.

Re: >>> STOP the oil spill NOW >>>
BP needs to get the pressure working for them, not against them. Remember Prof. Julius Sumner Miller physics fans? You can karate chop a yard stick with just the air pressure that's on a sheet of newspaper. At 2000psi they have all the pressure they need to cap that well. And then, if they have to, they can glass parking lot the strata to keep it from leaking. Last resort? Maybe. But it won't be the first nuke in the ocean.

Maybe now that the pipe has been cut a "stint" type of insert could have a casing inserted center of expandable bladder that then could be inserted into existing casing and inflated within the existing casing
