Wanted: Creative Ideas for Dealing With Oil Blowout in Gulf
Editor's Note: The massive deep sea oil blowout in the Gulf of Mexico has been flowing for more than a month. Several potential solutions have been tried; all have failed. You and the other members of our worldwide audience of over 300,000 principal investigators, in all fields and specialties of research, comprise a huge reservoir of creativity. Innovative methods for solving this drilling crisis--or the next one--are needed.
We are inviting all scientists reading this Alert to immediately submit their most creative and novel ideas and concepts for stopping the oil flow and/or remediating the leaked oil. You do not need to be an oil specialist (in fact it is probably preferable you not be one)
Whether unusual or conventional, all submissions will be printed (subject only to normal editing). They may be signed with name, title and affiliation, or be anonymous. Please limit to 200 words maximum, no diagrams. Post your ideas.
The entire list of suggestions will be shown on our website, and the first 250 have already been sent to the Chief Executive of British Petroleum and The President of the United States. As this matter is urgent, kindly respond within 72 hours. On behalf of the worlds' citizens, thank you for contributing your nuggets of scientific creativity.

Lower a torpedo-like metal cylinder into the riser, which fits snugly, but not too tight.
Weight of cylinder slightly greater than (oil pressure x cross-sectional area of riser)
Lower it a few hundred feet.
Repeat top kill.

Spring load a 3 ft-diemeter flat umbrella (spokes on the outside, steel mesh between the spokes) around then end of a mile-long cable, with a titanium sheath on the outside of the spring-loaded umbrella and on the outside of the cable.
Put the cable into the well and pass it down into the oil reserve.
Pull the sheath back to let the pring-loaded umbrella deploy.
The force of the oil pressure gradient will push the umbrella against the open lower end of the pipe, slowing or stopping the leak.
Fill the pipe above the umbrella with concrete.

The ultimate question is what sorts of redundancies can be built into the system to allow for drilling at 1 mile depths? The blowout preventer failed. There needs to be a much more reliable system for killing the flow when things go terribly wrong.

In case not, BP may resume its top killer method. the previous failure of this method
was because the oil running-out speed is larger than the fluid injecting speed.
By squeezing some pipe section (instead of cutting off), the oil outflow speed can
be reduced. In this case, injecting speed can outpace the outflow speed.
just a second thought.

It does not require the crazy nuclear options that have been proposed. The deep water submersibles that are currently being used could place planned charges that would then be detonated in a controlled fashion. This does not require any new inventions or technology, just application of what is used above ground.

At ocean floor, as close as possible to leak, suction oil/water mix and inject it back into the ground.
Use radioactive material close to leak to break down oil.
Drill relief well extremely close to original well to speed process.
Sink a casing into the ocean floor around the leaking wellhead. Then cap it.
Fragment well liner so that oil seeps into surrounding rock layers before reaching the ocean floor.

Drill a new oblique well nearby and connect it to the old one under the sea floor. Pump oil through the new well to a ship. This reduces the oil pressure in the old well at the sea floor and makes it easier to seal the old well. The new well can be sealed later.

The petrol gushing from the bottom has an upword pressure of more than 16 Atmospheres, otherwise it would be stoppe by the water pressure, which at the bottom of 1500 m is close to 15 Atmosheres. Pozzolana sould be sent under a comparable pressure.
POZZOLANA is used in Italy since the roman times for underwater constructions.
Contact Italian ambassador to receive the necessary amount.
Please put this suggestion at the top.
Few people know that POZZOLANA HARDENS UNDER WATER.

For the future, redesign Blow-Out Protectors to be "closed" as the default condition. Use a shape-memory alloy (such as NiTi) as the valve device which, in the absence of external control from controllers (heat in the case of a shape-memory alloy), would snap shut if electrical or physical contact is lost. Install more than one as a secondary fail-safe. The current BOP required active closure which failed, resulting in the blow out.
Could it be that this is a nefarious plot by British Petroleum to float the newfound oil all the way to Britain on the Gulf Stream?

They have a maned robotic sub which has enough mass and thrust to manipulate items on the bottom to plug the leak. This allows visual to work better than small cameras.
Start allowing oil drilling where it is safe on land. Deep sea can be done once they prove they can fix problems.

YES, I thought of that right away!
My suggestion on DAY 2!!!!!! was to use a ship like the Glomar Explorer and place a concrete dome, with a ledge on top, over the sawed off top of the pipe. Then you could drop lead/concrete ingots over it to seal it to the ocean floor. After stopping the leak, counter drill another well to take pressure off of the "sealed" well.
Are those idiots in Washington the BEST we can do?

I'm a chemist, retired memritus prof. A potentially simple solution for the oil spill is
LN2 pumped into the flow near the holes, and down the pipe. The evaporation of the
LN2 would cause the oil to nearly solidify, or at least become quite thixotropic (think catsup),
thus slowing the flow enough to get aa handle on a permanent cap. It would take tons of
LN2. Placing apparatus to generate LN2 from the air at the site on ships would be a simple
solution to the supply problem.
Second, the LOC (liq Oxygen) co-produced from the air would help the cleanup. Submersibles
would bubble the LOX through the plumes of oil, thus saturating the light fractions (supplying aquatic
life simultaneously). Escape of the gaseous O2 produces volatile mixture which can be ignited
(Heck of a boom!) This produces sufficient heat to syeam distill more light fractionss into the
ignition zone for ignition. The heavy fractions do not flow well, and can be scooped up for salvage
more easily. This may not be a total solution, but maybe one to buy time till a relief well is in place.

A rigie pipe with a long inflatable "balloon" at the distal end could be inserted into the well. The balloon would need to be very durable but able to distend. Then, instead of just pumping mud and golf balls into the oil that's already flowing out, the mud can be pumped into the balloon, which will fill up and block the pipe. Friction and whatever machinery is used to insert the pipe will keep it all in place long enough to allow the well to be definitively capped.

Nobody asks the question: How come BP and other oil companies are allowed to drill in places where they cannot plug the well?
There was a news item early on, according to which: Safety equipment used by BP in North Sea oil wells, and required by Britain and Norway, are NOT required by the U.S. !!! Shame!

I have reviewed the following ideas with my son, who has his doctorate in physics, and he believes that it may have merit.
Basically, it would involve creating a large hill on top of the leaking pipe by dropping a mixture of gravel, sand, (and, perhaps, dry Portland cement) to cover the area of the leak.
(Some of the following data is from investigative reporting from the Wall Street Journal; the rest is basic physics.)
The net pressure at the leak is 400 psi.
The diameter of the pipe leaking oil and gas is 9 inches.
Therefore, 400 psi X 63.6 square inches = a total force of 25,440 pounds (~ 12.7 tons).
It would be necessary to drop a mass of gravel and sand to first cover to the top of the blowout preventer (BOP), and then an enough to exert a downward pressure in excess of the 12.7 tons of the pressure leak.
For perspective, 12.7 tons represents about 210 cubic feet of a mixture of gravel and sand. However, in water, its effective downward weight would only be about 2/3 of that, because of the density of water. So, it would take about 19 tons of gravel and sand (318 cu. ft. of gravel and sand) to oppose the upward pressure of the oil leak.
However, a single railroad car filled with gravel and sand would be about 10 or more times this amount of fill. (Typically, 3200 to 4000 cu. ft. per car.) Bottom-dumping rail cars (very common for transporting coal) could be lowered by crane to dump their contents.
Note: The dome that they lowered over the leak at the time of that attempt weighed 74 tons. So, they must have a crane on site that can handle large loads.
It might not take an especially long time to create the hill; it would not take any specialized technology, and would not depend upon BP alone.
I am not an engineer, but I do have some background in mechanics.
I would like to hear from you.

Real suggestion--the first big containment box that failed due to clathrates (methane hydrates: which should have been expected, look at the P-T relationship of methane hydrate formation / stability; my undergraduate students in Environmental Chemistry could have told them this!) may work now--that is, the earlier pictures revealed a hydrate plume (white to white-ish) while the more recent pictures don't. Is this because they have released the majority of the thermogenic methane head or, with dirspersants being added, do we just see them anymore. That is, if the methane proportion is in fact much lower perhaps the big box wouldn't freeze up. Also an earlier comment here suggested heatingthe box-try that too.

1. To contain oil while trying to stop the leak: Take a ~2 km-long ~5 mm-thick soft rubber/plastic hose that is ~ 1 m in diameter with excessive lead weighted funnel at one end that would be
placed over the Gusher. The buoyancy and turbulence of the oil would cause it to rise and fill up the "wind sock" like "hose) containing it until it reaches at the surface. The important thing
is that there is some rigidity to the hose so it doesn't collapse on itself, maybe using "hula Hoop"
or spiral coil also made out of more rigid material that would keep open the cross area of hose.
The hose at the surface could have a "pull-up pump" that would pull the flow up and into
rotating cargo ships or oil tankers (potentially allowing for future refining at a refinery). The "Pull-up pumps" could be running while the long~2 km hose is deployed from the sea surface to the seafloor, to make sure that it is not blocked open with deep water rising to the surface, and then use ROV's to drop it onto the small funnel with the heavy lead weight from ~50 m up down over the rising Gusher plume, and then once sitting on the seafloor, release any floats that allowed the ROV to move it, leaving only the heavy weights to keep it in place. This could further be attached to drilled in seafloor anchors as needed.
2. To stop Gusher. Place 72 powerful (military has many options) controlled explosives placed in the form of a ~20 m diameter and 100 m deep cylindrical grid within the seafloor surrounding the well pipe (maybe 12 in a circle at 10 m depth, 12 at 20 m, 12 at 30 m 12 at 50m , 12 at 70 and 12 at 100 m depth) and set up the explosions to be timed that they detonate the layers in a time sequence such that the deepest layer is detonated last (probably only need a few millisecond delays between layers, so that an overall TOP DOWN squeezing of the pipe occurs, at which time, more material can be placed over the area to fully seal the seafloor surface (large Cement cap etc).

Send a small wire-guided gadget with an electric propeller down through the oil flowing in the pipe, to its very bottom, and release a spring catch to open a very solid "umbrella" or clamshell, that holds itself against the rim of the pipe. That should be enough. The pressure of the oil below should hold the seal tight against the pipe, cutting off the flow. The pressure above the gadget is then lower than the pressure below.
Once this is in place, dump something in that hardens after a while, because now there is no excess pressure in the pipe, and anything that sinks in water will sink in the oil. Now you've formed a plug, and when it hardens, it's permanent unless you deliberately punch it out.
The oil flow velocity in the pipe is not huge, and an axial compressor off a very small model jet engine from the aeromodeling hobby community should do for the propulsion. It might take an hour to go down the pipe. The clamshell gadget to open out like a flower and form the seal, and the electrically-switched spring release for the clamshell should be pretty easy for any machine shop to build. It's basically the technology of an umbrella, OK, a sturdy umbrella built of metal not fabric.
This may be easy and quick enough for the present disaster, but at any rate it should be easy to develop for the future if the govt or oil companies are willing to try.
And when they are ready to re-use the well, if ever, they can just send another gadget down and push this one down and out of the way.
The pressures are all huge, but at any given depth the pressures are not very different all round, and there's nothing here that steel can't do.
Of course I must be blissfully ignorant of some other hugely simple but insurmountable problem, but ignorance is so cool. :-)
As for cleaning up the oil already spilled, well.. reversing entropy increase is a tough problem. Stopping the flow is the simple part, above.

However, methane hydrates can also be put to good use in this case. The key is to cause precipitation of the hydrates INSIDE the blowout preventer and riser pipe. This will require a mechanism to rapidly cool the oil to ~< 1oC (depending on pressure and a wide range of factors that are not totally understood).
I would therefore second the idea presented here and elsewhere that the blowout preventer and riser be cryogenically cooled either with liquid nitrogen or liquified natural gas to promote the precipitation of methane hydrates within the wellhead. The key will be to sufficiently cool the oil to cause methane hydrate precipitation before it erupts out of the broken riser pipe into the gulf.
It may even be possible to pump liquid nitrogen into the blowout preventer using the piping already put in place during the 'top kill' effort. Just be sure to flush out the pipes to get rid of entrained seawater. Either dry air if it can be compressed to that pressure, or some type of oil that will not freeze at 77K.

Steps:
1.Cut the pipe to obtain a clean cut surface
2.Attach a metallic flange (Flange #1) to the cut pipe. The inner diameter of the flange should be slightly bigger than the outer diameter of the pipe.
3.Weld that flange to the pipe (flange material should be similar to pipe material for ease of welding). Make sure that the pipe is flush with the face of the flange. Welding should avoid any future leakage.
4.Use a second solid “blank” flange (flange #2). Flange #2 should be same diameter as Flange # 1 and should include the same amount of bolt holes. Use four long bolts to bring the two flanges together.
5.Gradually tighten the bolts to close the gap between the two flanges until sealing the leakage.
Other Considerations:
1.A ring seal may be used between the two flanges to obtain a total seal.
2.Flange #1 could be initially cut in two pieces (2 semi-circles) for ease of assembly onto the pipe.
3.The 4 bolts shown could be welded to Flange # 1 from the onset.
4.The cut (in step #1) should be performed at a point where the pipe is perfectly round.
5.Cutting and welding could be performed with robotic tools currently available.

When oil and mud push the cages together, many cages will stuck together (opposite magnetic attraction or ligand-receptor shapes can be designed into the cage materials). Filling the stuck cage with mud mixtures should biuld a long plug above which more cages mixed with quick bonding cement can be poured.
The key is to first get multiple layers of two or more cage complexes stuk deeply in the well without blocking oil flow (no presure buildup). That may allow followup pumping of mud to form a long stretch of plud that will be strong enough to allow cement reinforcement bfore oil pressure push the plug back up.

The second piece of the collar should be a half cylinder that completes the first half cylinder with corresponding flanges. The flanges serve to secure the two pieces together around the existing oil pipe.
The third component is a plate that is machined to fit within the channel at the top of the cylinder. As the plate is pushed into position it would effectively cut off/cap the existing pipeline. Once secured, a more permanent fixture could be attached that would permit the capture of any future oil flow.

I propose a coupling to seal to the existing rough pipe using a self-tightening "chinese finger trap" approach. A suitable structure could be made of cables, lined with a flexible layer for better sealing to the pipe (low temp elastomer or even a thin metal bellows) firmly attached to a larger pipe and valve. The diameter of the longitudinally compressed trap can be sized to easily exceed the rough or crimped pipe stub, and then lowered onto the pipe. The back pressure must not prevent the fitting of the coupling, so any valve attached to the coupling must be open. When in place, pull down the ring at the end of the cable trap until snug, then allow the backpressure to build by closing the valve, pulling the trap tight. This will conform to the uneven surface as needed.
Such devices can be built in advance and be at the ready.

Develop hinged cylindrical encasement allowing attachment from the side of the outer pipe rather than the top. The cylindrical encasment would be hinged on one side with hydrolic closure mechanism and appropriate seals where cylinder will meet once closed around the pipe. The encasement would also have a cut off valve at the top of the pipe top which would be left open during the time the encasement is secured around the pipe allowing oil to continuously vent during the encapsolulation process. Once secured, the top valve could be activated stop the flow of oil.

This "cage" approach has been used by the Applied Physics Lab at the University of Washington to cut off and retrieve deep underwater "smokers" which are large metallic sulfide columns, very rough and uneven, and belching very hot opaque fluid. The cage was lowered over the column, and a chain saw like device was able to cut through many inches of metallic material, which was held by the cage and then raised to the surface for study and display in several museums.

The science behind the biosurfactant is, biosurfactants are amphiphilic molecules produced by microbes using hydrophobic substrates or even using glucose. These versatile molecules reduce the surface tension drastically. It also emulsify and disperse the oils very quickly, these two processes will make the oil available to the microbes present in the area.
Since, all biosurfactants are not produced in high yield, but one biosurfactant called SOPHOROLIPIDS can be produced in large quantity through fermentation and the reported yield is 700g/L. There are few published papers available on this biosurfactant and its influence in biodegradation. But no one has done study on its application in marine environment. I also known that some companies sell this product in market.
Since my Ph.D is on biosurfactants and their application in oil degradation, I am ready to provide more information in this regard. In may lab scale study I observed 25 to 30% increase in biodegradation rates as compared to controls without biosurfactant.
People may say that we can clean the oil by using mechanical devices and chemicals, but your again polluting the environment by adding chemicals and their resides will be there for ever. In physical clean up process like use of boomer, skimmers and in situ firing, these approaches can not clean all the spill oil. So it is not a complete cleaning. the only way is to promote the biodegradation of the oil through eco-friendly methods as I proposed above.

if this doesn't work the next is intra-arterial control of blood flow with a balloon device (as my colleges indicated above) this needs to be of a material that would be resistant to rupture or disruption of the balloon (thick rubber, kevlar etc) then inflate the balloon in the lumen of the pipe. Usually we use air to inflate the balloon, the hydrostatic pressure of fluid would work better here (much like the hydrolic bladders used to expand cruched cars)
this would stop the flow!'
a more sophistacated version would be a balloon that would have a central area through which the oil could be removed in a controlled manner.

The balance sheet in fiscal terms would show the cost of collecting the oil in the Gulf balanced by the profitability of the agriculture in otherwise hostile growing territory.
But the balance sheet in environmental terms is even better. The environmental problem in the Gulf is minimised as much as possible, while the environment in North Africa is substantially improved and becomes a signifiant contributor to reducing greenhouse gases (the plant life, including trees, is an absorber of CO2).
This is not a crazy notion. It's a serious way in which BP could also recover some of the reputational damage and help the longer term issues of saving the planet.

1. Pour enough amounts of surface functionalized magnetic particles in this area, and the surface functionalization can make the oils bind to the particles.
2. Use ships or anything else which can move in this area taking some objects with magnetic fields to attract the above particles on the magnetic objects.
3. Remove the magnetic fields on the objects to release the oil immobilized particles to re-generate the oil.

I think maybe to take the "ballon effect," by using the same material used to block the oil spill from reaching the gulf shores, place it over the open hole until its filled, cap it off, let it float in the water until you guys come up with some way to dispose of it. Or maybe just use the "Hefty effect," cover the spill with the heavy duty rubber material, let it fill, use a draw string to close the ends, let it float to the surface. I think people on the gulf region will not mind looking at the ballons floating in the water knowing it is contained, rather than the oil, gas, and mud.

Pollow it with another 5" thich 12 inch pipe, then a smaller pipe till you can lower a solid cone to reduce the flow to a point you can plug it. There will be oil coming out between the pipes but it will be reduced to the minmum.
OR can you drop cannon balls smaller than the 21 inch oil pipe . Fill it close to the surface with large steel balls, then small steel balls . This will reduce the flowing oil as well as the pressure where you can cap it
Good luck

explosion of weak nuclear bombs or by emptying big stones from
big oil tanker ships just above the well or hitting the oil well by
many strong submarine torpedo. it is possible to have explosion ring all around the well(s). two stroke torpedo seems more appropriate.
the second plan may be; decreasing the outlet pressure (dm/dt) of oil by making many connected wells close the main oil wells hence dividing the outlet dragged-oil among all of them then sealing one by one that is much easier.

Seriously the news media is way out of their zone in hyper ventilating and aggravating the general public (not that it has any effect but it complicates how people who are working on the issue address this problem). I bet each one of them has no clue how oil was ever discovered and how difficult it is to get them and refine it. For all those who think who can live without oil, remember this is still the best technology available. The next best efficient technology thats available is nuclear. (how are we going to deal with that? some day everyone will have to turn to this and not use it to kill each other). Efficiency is the key in energy policy. Let the BP engineers and govt. scientists do the job. Rest if you can legitimately get on board and contribute do so else should stand and watch. time is the best fix)
To be fair for BP, they would like this well to be still functional and not have this cleanup problem.
Now,
Initially I was thinking that may be a giant crimper (like a can crusher) would do the job. It will reduce the oil out flow but also leak just a little bit to keep the wells from blowing up.

All current approaches will fail. The first hurricane will wipe out the marsh and instead of the absurdity of wiping oil off of individual blades of grass, rags will be wiping oil off of the beignets in Jackson Square.
There is only one answer and it is sitting right in front of everyone. Reverse the arrows that are directing water and oil movement.
Army engineers can do this, no question: remove the levees south of New Orleans and redirect the fresh water and alluvial soil into the dwindling marsh.
Result. All the grass will be washed, not wiped individually. The alluvial soil will be deposited as it has been for millennia and rebuild and extend the marsh. The salt water now creeping into the marsh will be diluted. That will with time protect the city and restore the crucial fishing estuary and wild life sanctuaries.
Some communities might be flooded, but those places depend on the seafood in the gulf, so those people will move anyway.
It’s a win-win-win. The marsh is cleaned. The marsh is rebuilt. The fishing is restored. New Orleans is saved by the marsh storm buffer.
Currently the oil moves north: tides, currents, storms.
The mighty Mississippi can beat the whole problem.
Unfortunately, we have no John Kennedy to unite the whole country to go to the moon.

Leaks can be stopped by the diffusion of source pressure though many small channels. These small channels are then less difficult to obstruct and block. Methods: First, US navy submarines will explode the oil pipe site with downward (45 degree) traveling torpedoes. A crater as deep as possible (20 meters?) into sediments and bedrock will be created and the above surface well casing blown away. After this crater is formed several possibilities will present themselves. The addition of large amounts of heavy and large aggregates (metal ore, compacted scrap iron, crushed vehicles) could be a first method for diffusing the pressure into more and smaller channels. After this addition, filling the crater with gradually smaller and smaller heavy aggregates would be necessary. Heavy barium clays could be used between aggregate additions. Alternatively or additionally explosives could be used to move the crater rim back into the depths of the crater and over the oil pipe emissions. Also, explosives could be used to move fine aggregates over the diffused oil emissions of weakened pressure. Small explosives could be used in the heavy aggregates of the newly filled crater to decrease the size of the channels.

For the second problem as the oil spread we need to a way to stop it from expanding and that could be by spreading another materials in a bigger circle so when the oil leak expand cant not spread outside that, then we start swallowing that oil leak.

In metric terms this well was drilled to 5468m with 1.7gm/cc density mud in water with a depth of 1524m.
Assuming the oil gas mixture has a density of 0.8gm/cc one can calculate that the reservoir pressure is somewhat below 92.956mpa, and the flowing pressure at the sea floor is 92.956mpa minus the pressure from the oil column of 31.696mpa for the 3962m column to the sea floor which equals 61.260mpa for the pressure at the sea floor.
This converts to pressures of 13,482psi for the reservoir pressure and 8885psi for the sea floor pressure.
Assuming an ID of 6 inches for the casing the cross sectional area for the flow is 28.27inches and the total force of the flow at the sea floor would be 251,217lbs.
Rounding off these numbers to 125tons and 13,000psi we have a very much simplified problem.
To stem the flow of oil we either need to cap the well with a 125ton "cork" or stop the flow at the reservoir with a mud column that will exert 13,000psi of pressure.
It should have been readily apparent that any attempt to cap the well at the sea floor had very low possibility of success and the only way to stop the flow is with a sufficient mud column holding back the reservoir pressure.
This will successfully be achieved with the relief wells and the question is whether this can be done sooner.
The last operation opened up vertical access to the well bore. If 4" drill pipe can be lowered past the BOP all the way to the bottom kill mud could then be pumped down the drill stem and be delivered to the bottom of the well at the reservoir level. It would take almost the full height from the reservoir to the sea floor for standard kill mud to accomplish this, but if hemitite instead of barite was used this could be accomplished with about three quarters of the column with this denser material.
With the riser already in place the drill pipe has an easy access to the well bore and this should be very similar to just tripping into the hole to TD.
This tripping operation should take under a day to complete and it would take only a few hours of pumping mud to completely stop the flow and get the well under control.
This is a simple and straight forward operation and providing the pipe can enter the hole and get to the bottom it is a virtual certainty that the flow can be stopped within two days.

This proposal is about augmenting biological remediation in a global scale.
Proposal:
Use synthetic biology techniques construct at least three alternative Halobacterium NRC-1 strains that can biodegrade most of the components of crude oil in saline water, by coupling the degradation pathways genes obtained from other bacteria to the energy production pathways in Halobacterium. Optimize efficiency by systems biology modeling (e.g., flux-balance modeling), mass produce in fermentors, produce aerosols and disperse into contaminated areas.
Background:
Crude oil is composed of hydrocarbons that are mostly paraffins, napthenes, small aromatics and less than 10% polycyclic aromatic hydrocarbons.
Biodegradative pathways of nearly all of these hydrocarbons are well known—they have been best studied in soil bacteria, such as Pseudomonads and Mycobacteria, for example. These bacteria do not survive well in salt water. However, salt-loving Halobacterium NRC-1 does not have these genes, so these need to be engineered in.
Method:
The engineering steps will include assembling all the genes into a single genome of Halobacterium NRC-1, coupling some of the encoded proteins, such as key rate limiting metabolic enzymes, into protein scaffolds so that maximal metabolite flow rate is obtained through the pathways. Some of the degradative enzymes are to secreted (such as those catalyzing the first steps of degrading larger (more insoluble) molecules, some are membrane bound and some are soluble (these information are available from computational analysis of genomic sequences in public databases). The engineering design would have to take into consideration the need for such spatial distributions. The designed strains will be constructed by high-throughput DNA synthesis and assembly techniques innovated within the past 5 years. Designs would be guided by computational modeling of pathway operation and dynamics. The constructed strains will then need to be optimized both for mass production and degradation efficiency—the fastest way is by repeated cycles of mutagenesis and selection. Whole genome sequencing, computational modeling guided by metabolome profiling, and gene/protein expression profiling, will be required at every stage of optimization. Mass produce the engineered strains in massive scale, roll into aerosols or powered dispersants, and release in contaminated areas. All of the above steps are technically feasible.
Potential impact on ecosystem:
This will be substantial but no more than that of the oil itself. Since the energy production in the engineered strains will be coupled to biodegradation of the oil residues, the engineered strains will die as they exhaust the energy supply (oil residues).
Resources:
A group of approximately 150-200, most young, scientists, including trained bacteriologists, biochemists, molecular biologists, and computational biologists, especially those trained in genomics, and chemical/industrial fermentation engineers, are to be led by a team of synthetic biology researchers in a management format recapitulating the Manhattan Project.
Time:
Approximately 1 year to delivery (six months to assemble the strains, 3 months to optimize, 3 months to production).
Yes, it is ambitious!

To place this in perspective, the use of , say, an 18 inch diameter steel cylindrical plug having a long tapered entry profile (to reduce the initially encountered effects of turbulence)would require a length of approximately 500 ft (200T). Full insertion of such a plug would require a knowledge of the alignment and bore restrictions. The progressively increasing impedance of the annular ductway during insertion would ensure a controlled reduction of oil flow. The maximum length of the fabricated sections would be determined by manufacturing, joint design, transport and assembly considerations.

The exfoliated graphite is the best candidate to remove all the crude oil from the water. The maximum removal capacity is 103 kilogram of oil removed per each Kilogram of the exfoliated graphite, which is the highest, in less than one minute. The exfoliated graphite is floatable, so that it can be used in two ways: (1) It can be injected to the well where it will adsorb the crude oil and then it will float to the surface or (2) it can be wrapped in fiberglass to form a boom and then applied to the spill directly in case of calm weather. The oil adsorbed by the exfoliated graphite can be recovered by centrifugation and used again and the used exfoliated can be recycled as well up to six time with 60% efficiency for the last cycle. The site will need location to place some furnaces, pumps and the exfoliated graphite precursor which is the graphite oxide, this material can be obtained from Asbury Carbons in New Jersey.
I have been awarded the very prestigious Fulbright scholarship to pursue my MSc. in The Penn State University. My project was the remediation of oil spills, and I am currently awarded the very prestigious Alberta Ingenuity scholarship toward my PhD in the University of Alberta, for an advanced remediation project as well.

An artery is bleeding at the bottom of a long dark hole.
1) Containment (apply appropriate suction): Construct a square pyramid of strong (multilayered) cold-hot resistant (antartic tent material) "canvas" that is lowered over plume via lines (or guided into place with ballast) with base secured by concrete footers (cubes) along perimeter-corners and vertex lifted to "point" with negative ballast (balloons). Vertex has been removed previously and joined to square cylinder "chimney" of same material that passes to surface collection point ("chimney is thus flexible"). Dimensions depend on width and pitch of oil-plume. Upward flow to vertex, chimney, and surface assisted by gas injection beneath "tent" (volumes adjusted for anticipated expansion during ascent) or warming of sea water with electric heaters. Imagine a circus tent (aquatic version) with a vent in roof (joined to chimney of cloth rising to surface) with "smoke" rising upwards by convection (and/or assisted by bubbler -- now think corner filter in your 10 gal fishtank). Oil is collected at surface. Tent is preformed and lowered into position. Suction achieved and operative field "controlled" -- hemostasis procedure follows (2).
2) Hemostasis (stop bleeding): Let's assume that the various capping procedures (clamping, cauterizing and shrinking) continue to fail -- can we "clot" the crude oil "in-line"? Surgical approach is to apply pressure and await natural coagulation (not possible here). HOWEVER: can we encourage sludging and/or solidification? IDEA: Cuff riser tube along its length with cooling rings (liq N2) and cool crude in transit (this would have been nice with pipe bent to slow flow). Multicomponent crude is said to become viscous near -50 deg C -- if viscous, flow will slow -- freezing may follow. If flow stopped or sufficiently slowed -- proceed with definitive capping OR use freeze technique(s) to create a saline ice "cap" around and over rise tube (might consider creating a cryo-cage that is placed over end with flow reduced and flash freeze saline within interstices via infusion coolant into cube railings (think a wire mesh 3D cube of pipes carrying coolant). Hemostasis achieved (maybe).
(1) and (2) are the natural and instinctive steps taken by surgeon confronted with a serious bleeding point located in a dangerous or tough to reach location. Principles: 1) clear the field of accumulating blood (suction) to prevent obscuration of problem (or spread of damaging heme) -- breath deep and think. 2) proceed with standard hemostatic maneuvers (here limited, it seems, to thrombosing vessel by slowing flow or "clotting"/freezing and/or slowing flow to permit routine/non-routine [freeze cap] occlusion).

A hollow tube turbine extended as needed on a boom over or under an oil leak is anchored to a ship, or stabilizing concrete counterweight on the ocean floor, and powered from engines aboard ships or the rig itself.
Attached to the end of the turbine in the direction of vortex flow is one or more flexible pipes siphoning leaking oil to tankers, barges, or ringed flotation containers. Decontamination ships can filter clean seawater out from the oil and return it back to the body of water.
The turbines can be made in varying sizes and shapes to adapt to surface oil, under tanker leaks, as well as platform or deep well conditions. Finally, these turbines, pipes, and containment units could be required equipment on all drilling and transport operations assuring immediate response.

2.Construct a cylindrical mesh screen with one end of the cylinder terminated with a thicker solid metal plate. The cylindrical diameter is to match the submerged pipe from which the leak is flowing.
3.Lower the cylindrical assembly alongside the robot that is standing by at the leak.
4.Arrange to have the robot (controlled by surface personnel) maneuver the cylindrical mesh assembly over the broken flow tube, and have the robot weld the mesh cylinder to the oil pipe.
5.Next, lower another cylindrical mesh but this one is hinged along its axis so that it can be opened and wrapped around the first welded mesh assembly; weld the latter onto the first. Now, the effective mesh diameter becomes reduced as does the leak rate.
6.Continue in succession to have the robot position and weld a number of such split cylindrical screens over, and around the assembly, until the overall mesh size is sufficiently reduced to effectively stop the oil leak –due to viscosity there will be a pressure drop across each mesh. The average force on each outer layer of mesh becomes reduced, so only the total wall thickness of the total number of meshes should be sufficient to withstand the oil pressure within.

Take a small diameter pipe and thread it deep into the casing or rock from which the oil flows. At the end of this pipe you have one or more retrograde jets. (The jets point backwards in the same direction as the oil is flowing) This retrograde direction will cause the flow of oil to pull material through the small pipe and into the main flow using the venture effect. Inject material through these jets that will combine with the oil to form adhesive materials. Having this pipe deep into the vent will allow this material more time to adhere to the surface of the casing or rock slowly building a crust inward in the vent. According to Poiseuille’s law if the radius can be reduced by 1/16th the flow will drop 50%. Over time the vent will slowly loose patency and the occlusion will stop. A second small diameter pipe could be fixed to the first pipe and it could extend a smaller distance into the vent. This pipe would be used to sample the adhesive byproducts and to measure the rate of flow through the main vent.

Every idea that requires new and novel materials be produced in quantity along with the equipment to utilize them is too slow.
Every 'insertion or balloon catheter' idea that ignores the force from the outlet (pipe cross sectional area times net flow pressure) is probably unworkable especially if it requires some large specialized item(s) be constructed.
Every 'bury it in debris' idea will spread out the flow and reduce pressures locally on top of and around the mound but WILL NOT STOP the leakage and blockage of the reduced flow at any point on the mound will increase the pressure and flow over the rest of the mound.
Every 'inverted funnel, water tank, derelict ship, rubber sheet collection' idea must take into account the buoyancy of the water and of the oil/gas mixture. Some of these might work if they are kept simple but they will not stop the leak; only minimize the damage.
Every 'cover it with a weighted dome' solution that does not account for the increase in force due to an increase in the cross sectional area of the flow will likely fail as the dome lifts or the flow blows out through another path; perhaps in the sea bed itself.
Every 'collapse the pipe with an explosion' plan that does not apply sufficient force to collapse enough of the pipe sufficiently far under the sea floor so as to oppose the pressure of the flow (both through the collapsed pipe and through the sea bed material by itself) will fail as the pipe blows out again or ruptures lower down so that the leak is through the sea floor material. Conventional explosives appear inadequate in virtually every scenario.
Every plan that requires excessive or complex manipulations be performed at depth is also unlikely to succeed given the difficulties of working at depth in the ambient environment. This probably includes crimping or bending of the pipe unless stock equipment designed for the purpose already exists.

We can dump debris on it if it gains us anything.
We can cut and weld at depth if we keep it simple.
We can perhaps turn nuts and bolts at depth assuming that the equipment for the purpose already exists.
We can cover the outlet with something if it gains us anything.
We can use a nuclear weapon to seal the well which is a tested technology even if it is a politically incorrect suggestion.
Beyond this, the capabilities of the existing technology are fairly limited.
If capping the well with the capability of future access is the goal, we need to discuss what can be done NOW with what is CURRENTLY available for use and we need to Keep It Simple Silly (KISS). Obviously blowing it all up won't work from the future access point of view even though that would be the simplest solution. The same thing applies to simply welding on a solid cap as it is held in place by something really heavy like a submarine pointed downward with engines revving (assuming such welds would be expected to hold against the pressure).
The original cap (inverted funnel) idea seems the best bet for this with modifications to prevent the outlet from icing over since it is on the site already. This is a weak solution in the long run, however, because the cap does not seal to the pipe and the flow cannot be turned off.
There should exist in the world oil drilling inventory a valve designed to fit over a pipe of the given diameter or which can be easily and quickly modified to do so with an appropriate pipe stub. Take such a valve, modified as necessary, open it fully, lower it (or the stub) over the pipe end allowing the flow to continue unimpeded, then weld or clamp the valve to the pipe as appropriate depending on the materials from which the pipe and valve are made. Finally, close the valve. This should work if the pipe is not damaged somewhere else down the hole such that the flow has an alternate escape route.
Also, as Dale C., June 04, 2010 said the end of the pipe might actually be unboltable and a replacement part with appropriate valving could be attached. Or maybe it is as simple to fix as indicated by DM, June 04, 2010 "Fix the valve to shut the pipe."
Finally, attempts to pump in sufficiently dense mud might work if the fill is done from the bottom of the hole where there is no major developed flow pressure to overcome. Presumably such drilling mud can be removed once the well head is appropriately repaired.
Beyond this it seems there are relatively few rapidly deployable options.

Use a torpedo-shaped weight heavy enough to overcome the force of the oil stream exiting the well pipe, and narrow enough to actually enter the well pipe. The weight is attached to a cable that can be extended to the desired depth from a vessel on the water surface. Above the weight should be attached one or more (in series) heavy-gauge inflatable rubber bladders connected to high-pressure air lines.
Use the submersible robot to assist guiding the weight into the well pipe. Once within the pipe opening feed addition cable to lower the deflated bladders as deep into the pipe as desired... Inflate the bladder(s).
Once bladders have been inflated, additional mass can be dropped into the well pipe to prevent the inflated bladders from being forced upward as a result of their own buoyancy plus any pressure inherent in the oil well. Alternatively, drill two holes on opposite sides of the exposed portion of the well pipe: Once the bladders have been lowered into the well pipe, pass a bar through the holes in the well pipe to prevent the bladders from being forced out of the well pipe once they are inflated.

Blocking crude oil inflow at the bottom of the well pipe will either stop or drastically reduce the outflow and pressure of crude oil at the top of the pipe, allowing a top kill.
STEPS:
Push a deflated balloon mounted with a submersible pump on the end of a stiff metal cable into the oil well shaft, like a string into a straw. Continue until the cable end protrudes far into the reserve of crude oil beneath the sea bed, past the turbulence of the oil inflow.
Activate the pump to inflate the balloon with crude oil.
Pull the balloon into position at the bottom of the well pipe.

We propose to place our TB in a pipe with hole on the side (PipeH). Holes will be near the pipe’s end on the length with must be shorter than the length of the existing pipe placed in the rock. The outer diameter (OD) of our pipe must be smaller than inner diameter (ID) of the existing pipe. We will place (attach to) our TB in PipeH and use a standard method connecting many short pipes together in order to place our PipeH with TB in the existing pipe so that ends of both pipes will be in the same depth. In the next step we will push TB that its first bristles will pass pipes’ ends and spread outside blocking TB up movement. Other bristles should also spread through our PipeH holes touching the wall of the existing pipe. As effect of this stage we will get an anchor that can be also used for other purposes. In the next step we should inject a plastic or other glue through our TB handle and bristles. It should seal both pipes together.

However, I do have a comment on future drilling. I think there should be a method for rig workers to stop any unsafe action they think is occurring - similar to the ability of Toyota workers to stop their assembly line. In the current accident, many rig workers felt that they were being pressured by management to rush to complete the job, but there was not a method for them to report this problem up the BP management chain or to government oversight folks.
Hopefully by using best practices from other industries, the oil industry could improve its performance.

Publish the thinking and efforts of those engineers whose ideas have been tried.
Arrange the ideas of submitters in categories, such as NON ENGINEERING, NON-STOPPING, CAPPING, FUNNELING, EXPLODING, FREEZING, etc, so we can ignore those whose ideas we do not respect.
I think those closest to the job probably have the best ideas, and I am also glad to have an open forum.
Until they cap the leak, I suggest a truly giant circular or oval oil barrier surrounding the center of surfacing of the leaking oil. This barrier might have be 10 miles in diameter and downstream from the hole. Separate the oil and ship it out of the oval.

The size of the enclosure will depend on the size of the leak. The exit tube and control flows if needed will be scaled accordingly. The same concepts can be employed to devise an intake tube designed to be inserted into the leakage hole.
I am a Ph.D./P.E. in Mechanical Engineering specializing in fluid/thermal sciences with 25+ years in applying flow control to practical situations. Multiple patents. My company Sinhatech and I will perform the design and guide fabrication/installation.
We need assistance in fabrication (metal cutting/welding/machining) as per our instructions near the jobsite. We also need assistance in lowering/installing our device .

2- From outside the pipe, run four (one on each hole) hoist metal cables through these holes.
3- connect one end of each cable to a cap (a thick, round, rubber padded Disk) and the other end of each cable to a pulling device (ship, submarine...) and pull cables in opposite directions until the disk seals the pipe.
During the process of pulling, devices need to pull with equal force (not a very easy task)

Method: Tak a couple hot air balloons, and then put one inside other. Steel cable (cut to fit pipe) 'hat' net encapsulated balloon and anchors balloon to an air-injector pipe inside the balloon... Now a 'plug'
Air hose affixed back of injector sticking out of bottom of 'plug'. Pipe inside 'plug' has holes along the length allows air to fill from sidesTip. (Baffles inject more symmetrically then nozzle).
Deflate loosely furl 'plug' around injector. Place inside 'penetration tube' (2 halves of a container shaped like a Torpedo. Plastic break away latches secure 'payload' in penetration tube.
Insert at well breach, deploying it to the proper depth, then inject air into 'plug'. As the 'plug' inflates it presses and pops the latches. 'plug' should have sufficient mass to displace oil in well. Inflates side to sideup-down well, filling well to walls 360 degrees-injects mudgravel behind 'plug' to proper metric tonnage to prevent oil pressure from ejecting 'plug'.
Result: Uncontrolled discharge is terminated.

Then drop a bell cap with a pipr or fabric sleve from the surface over the submerged silo to direct the plume to a workable depth where it can be pumped into a separator that extracts the oil and returns the water to the Gulf. Natural gas may be captured, but much of it may need to be diverted for burn-off.
It may be possible to start to fill in the silo creating a column of mud and material that has enough weight to stuff the leak. It may be a follow on to the secondary wells being drilled now to remove pressure.

Then they insert a smaller pipe (of smaller diameter) to fit exactly into the pipe above and continue this process with 3-5 pipes of consecutive smaller diameter until the oil is leaking as a small jet, which can be pluged by a full circumference steel rod rammed from above by a robot. All of this can be done with the help of the company who manufacture the BOP. This needs co-ordination of BP engineers and the company that manufactures the BOP.
I think this also needs engineers / committee set up by the white house to oversee BP who are working alone without any outside help; every day lost is destroying the most precious natural habitat in the gulf. Please no more oil dispersant chemicals.

Volcano throws out ash -> weathered ash turns during into smectic clay -> the smectic clay adsorbs organics -> clay precipitates on ocean floor -> ocean floor is subducted while carried along by convection current in the Earth’s crust -> smectic clay reaches large depths and turns into illite clay -> the adsorbate desorbs and turns into oil (which separates) -> at larger depth the illite clay turns into magma -> the magma is thrown out by a volcano.
The key point: smectic clay adsorbs oil, which is already widely applied for removing odorous sulfur compounds.
Use the clay carried by the nearby Mississippi, ‘the big Muddy’. Mixing the fresh water of the Mississipi with contaminated salt water may require some channeling, but it seems a simple and quickly feasible solution. The oil rig seems to lie straight in the path of the Mississipi. Much of the leaked oil seems to have vanished. Maybe the process is already working!

Then the Federal government uses this money to pay for Coast Guard and other Federal, state and local cleanup efforts. It also disburses compensation payments, eliminating BP's slow and ineffective process.
The biggest thing this does is it lights a fire under BP's ass to try to actually *stop* the oil flow and not merely collect as much as they can for sale, which is all they've been trying to do since the rig exploded.

A large flexible plastic insert should be joined to the leaking pipe and the flow not stopped but redirected to the surface to be collected. Over time the pressure will lesson as the oil flow is collected, at that point 'capping' or plugging could be considered.

dear B.P. I know that this is not the best idea of the world
but think about what am going to say.
build a huge block of cement that can weight thousands of pounds
and cut it from below close to the sand and place it on top.
Another thing that i have is that if you make like an umbrella
thing that can hold the pressure for at least more than two hours.
and stick it in to the pipe and with air pressure push it down the
pipe till it reaches bottom. and once it reaches stop air and
the umbrella thing will open and block at least some of the
pressure. and thats when you put the mud with
the cement.. and when it breaks the cement will be blocking the
pipe and will be dry by then......... hope you can try this..

Weld a bolt on the flange of a valve then add weight to overcome the pressure.
Install the bolt into existing flange after removing the flange thats there, then install the bolt and put a nut on it.
Do not tighten the nut so tight that you cannot swivel the open valve.
Swivel the open valve around and install a bolt 180 degrees and snug it down and finish installing the other bolts.
Then close the valve and finish up with piping so that you can allow oil to be pumped into a tanker and sell the oil.
