Um. A 737 crashed into the Empire State Building without terrorist involvement so yes, planes crashing into building are a possible "natural" outcome.

Another Patranus fantasy... you really need to hire a fact-checker.

The only plane that ever crashed into the Empire State building was a B-25 flying in bad weather long before the development of modern avionics and flight controls.

peoples stupidity makes me angry. everyone thinks this is easy, that they are just stupid. Ever see something designed to go miles into the earth?
(like the tools i use on a daily basis) the design factors get damn complicated.

Herm,

Since my rig is shut down until further notice... how much training do i need to transfer to your division? Seriously thinking about filing a claim with BP for possible loss of income. My rig was just about to start drilling a well. Nice steady schedule with the guarantee of a steady and relatively fat paycheck. Instead, I am being sent in halfway through my hitch, with no idea of my job security.


I've been doing my best to stay out of the oil spill related threads except to add some insight and clarity on what i have observed to be normal SOPs on for rig ops.

Nobody has a plan for every contingency on anything.

BP knows how to fix this, and they will. Being a mile underwater, it's always a difficult task.

Umm I'm sure they will fix this eventually but yes it is a difficult task. Every thing they have tried has so far failed specifically because it's a mile underwater. The containment box should have worked but they didn't foresee the methane clathrates, the kill shot should have worked but it's only been tried effectively on land, the blowout preventer might have been fixed if it were on land or in shallow water that divers could reach. Everything they try turns out to have some new unexpected twist because nothing like this has every been done a mile underwater. Not saying it won't eventually be fixed but yes difficult it is.

I haven't read the details, but my supposition is that any nuclear device would be sunk very deeply into the well and detonated in order to fuse the rock, creating in effect a mass of melted and re-solidified rock to act as a plug. I don't think it would require a huge device (relatively speaking), just something to generate a lot of heat quickly.

If that's wrong, I'd appreciate someone correcting me.

Because of presure in this well you wouldnt be able to send it down - new well would have to be drilled close to current one at least 1000 meters (3000 feet) deep - if you detonate 5-10 KT nuke there it would colapse/crush current well and stop the leak.

Reason why I dont think nukes would be used even in extreme case is that if you drill paralel well close, you dont need nuke - 100 tons of normal explosives should be enough if new well is within 100 meters from original well.

All three times Russia used a nuke on a blowout it was on land, they have never done it underwater and certainly not at a mile deep.
Two questions:
1) Would a nuke be able to handle the pressure at ~5000 ft depth of water without self-detonating?
2) If the nuke requires a signal to detonate, would the water prevent said signal from reaching the nuke?

They've spent nearly $1 billion to date trying to cap the well. Apparently nothing they've tried so far has been inexpensive. Less expensive than other options, maybe.

yup...1 billion. their quarterly profits are what?

1. yes
2. no (signal would be send via cable anyway).

This may sound like a dumb question but I honestly dont know, so I have to ask.

Does anybody know how much oil is actually in that well?
A billion gallons? A trillion? Too much? Not enough?

It failed in 1979 in 200 feet of water.

What made anyone think it would work 31 years later in 5,000 feet of water?
I assume you're down there working on it and lending a hand with your expertise?

I mean, there's certainly no chance that technology has improved in 30 years or anything.

50 million barrels or more . . .

i wonder if that's even accurate. a problem they're having with deep water projects is that it's so expensive to drill test wells (which would normally map out a field) that they have to rely on calculations with a lot less data behind them. in the case of BP's thunderhorse field it seems to be turning out that a lot less oil is down there than thought.

Actually technology has advanced enough that we can safely remote detonate a small yield Nuke in an ROV.

They didn't have that option 31 years ago.

The use of nuclear explosions to seal off natural gas leaks certainly was tried, mostly successfully, in the past. And it may be the only option that has some certainty of being effective in the Gulf.

The depth of the explosion will certainly contain the radioactivity and the overpressure and heat will likely fuse the immediate area of the controlled explosion.

There have been many undersea nuclear tests, so this is likely not a subject that is foreign to the US, though it would be important to consult the Russians as those who have the most detailed documentation on the past analogous uses of nuclear devices.

There is quite a bit of literature on this, here is one link that offers quite a bit of information...

The Soviet Program For Peaceful Uses Of Nuclear Explosions

Excerpt -

Excerpt:
In the middle of 1966, a crisis in the gas industry suddenly offered an opportunity for a new application for peaceful nuclear explosions, the extinguishing of runaway gas wells. Successful closing several such wells in 1966 and 1967 gave growing confidence to the leaders of the program, and they began to think about a broad spectrum of new applications. …

Urtabrdak
On December 1, 1963, while drilling gas Well No. 11 in the Urtabulak gas field in Southern Uzbekistan about 80 km southeast of Bukhara, control of the well was lost at a depth of 2450 m. This resulted in the loss of more than 12 million m3 of gas per day through an 8-inch casing, enough gas to supply the needs of a large city, such as St. Petersburg. Formation pressures were about 27@300 atmospheres.

Finally, in the fall of 1966, a decision was made to attempt closing the well with the use of a nuclear explosive. It was believed that a nuclear explosion would squeeze close any hole located within 25-50 m of the explosion, depending on the yield. Two 44.5-cm (13.5-in) diameter slant wells, Holes No. 1c and 2c, were drilled simultaneously. They were aimed to come as close as possible to Hole No. 11 at a depth of about 1500 m in the middle of a 200-m-thick clay zone. This depth was considered sufficient to contain the 300-atmosphere pressure in the gas formation below. A number of acoustic and electromagnetic techniques were used to estimate the distance between Hole No 11 and inclined explosive emplacement hole at 1450 m. The final estimate for the closest distance between Hole No. 11 and Hole No. lC was 35 + 10 m.

The location for the explosive in Hole 1c was cooled to bring it down to a temperature the explosive could withstand. A special 30-kt nuclear explosive developed by the Arzamas nuclear weapons laboratory for this event was emplaced in Hole 1c and stemmed. It was detonated on September 30, 1966. Twenty-three seconds later the flame went out, and the well was sealed.

Pamuk
A few months after the closure of the Urtabulak No. 11 hole, control was lost of another high-pressure well in a similar nearby field, Hole No. 2-R in the Pamuk gas field. In this case, drilling had progressed to a depth of 2748 m before the gas-containing horizon was encountered, and gas pressures were significantly higher than those at Urtabulak (580 atm). A month and a half after the runaway well started, it blocked itself at a depth of 80&l 000. Remedial work was done in the well and appeared to have resolved the problem when, four months later, gas started coming to the surface through other holes and through the ground itself.

After several unsuccessful attempts to seal the well by hydraulic fracturing from a slant-drilled well, it was decided to again use a nuclear explosive to pinch off the runaway well. A new inclined hole, No. 10-N, was drilled to intersect Hole 2-R in the middle of a salt formation that overlay the gas producing formation. Measurements after it had been drilled indicated that the minimum separation distance at a depth of 2440 m was 30+ 5 m.
This time, a special explosive developed by the Chelyabinsk nuclear weapons laboratory was used, one that had been designed and tested to withstand the high pressures and temperatures in excess of 10O”C expected in the emplacement hole. It also was designed to be only 24 cm in diameter and about 3 m long to facilitate its use in conventional gas and oil field holes. Its yield was 47 kt.s 1 The explosive was inserted into Hole 10-N and detonated on May 21, 1968, at a depth of 2440 m. Because of the large amount of gas that had infiltrated the overlying strata during the preceding two years, the flow continued for seven days before it finally died out and the seal was complete. The second “success” gave Soviet scientists great confidence in the use of this new technique for rapidly and effectively controlling runaway gas and oil wells.

“Crater and Fakel”
Some four years later, two more opportunities arose for the use of nuclear explosions to extinguish runaway gas well tires. The first, code-named “Crater,” was in the Mayskii gas field about 30 km southeast of the city of Mary in Central Asia. Control of the gas well was lost on May 11, 1970, and about 700,000 m3 of gas was lost per day. The producing horizon in this field was at the 3000-m level. No details have been made public about this application, except that on April 11, 1972, a 14-kt explosion at a depth of 1720 m in an argillite formation was used to successfully seal the runaway well.
On July 7, 1972, another runaway gas well in the Ukraine, about 20 north of the city of Krasnograd and 65 km southwest of Karkov, was sealed with a nuclear explosion. The runaway well was in the Krestishche gas formation at a depth of over 3000 m. No additional information has been made available except that for this event, named “Fakel,” a 3.8-kt explosion at a depth of 2483 m in a salt formation was used. The small yield would indicate that the location of the runaway well was well known, and the explosive emplacement hole was drilled to be very close to it at shot depth.

“Pyrite’
The last attempt to use this application occurred in 1981 on a runaway well in the Kumzhinskiy gas deposit in the northern coast of European Russia near the mouth of the Pechora River, 50 km north of the city of Nar’yan Mar. Control of the well was lost on November 28, 1980, resulting in a loss of about 2,600,000 m3 of gas per day. On May 5, 1981, a 37.6-kt nuclear explosion, code-named “Pyrite,” was detonated at a depth of 1511 m in a sandstone+ lay formation near the runaway well. However, the nuclear explosion did not seal the well, perhaps because of poor data on the position of the runaway well. No additional details have been published on the results of the nuclear attempt or of subsequent efforts to close the well by other means.
Of the Soviet attempts to extinguish runaway gas wells, MinAtom reports that all were completely contained, and no radioactivity above background levels was detected at the surface of the ground during post-shot surveys.

I figured the some in here would *LOVE* the new-cu-lar option but it won't work. Russian scientist who proposed it said only 10% chance and people are running with it like it's a panacea now. There is simply too much pressure. Throw some sand in a running hose and let me know how that works for ya.

Plus you risk making hole bigger and uncappable ever!!!

No

800,000 barrels leaked/50,000,000 x 100 = 1.5% leaked

or 98.5% is still in ground or about 100x.

That PBS thing says worst case flow put it at ~170,000,000
That is somewhere around 4 million barrels.

50/4 = 12.5

Anyways there are a lot of dead dinosaurs still left to leak into the gulf.

What do you guys think of something like this???

1. Blow off BOP well head with conventional weapons
2. Get a very long cone solid steel like 100 ft & 100,000+ lbs
3. drop it in hole

???
