DoE Posts Raw Data From Oil Spill, Coast Guard Asks For Tech Help 138
coondoggie writes "The US Department of Energy this week opened an online portal where the public can get all the technical details it can stomach about the BP oil disaster in the Gulf. The DoE site offers online access to schematics, pressure tests, diagnostic results and other data about the malfunctioning blowout preventer and other problems in the ongoing mess. This comes alongside news that the US Coast Guard has issued a call for better specialized technology to help it respond to the ever-widening spill. The Coast Guard is looking for all manner of technology, such as advanced wireless sensors to help it track the movement and amount of oil in the Gulf, or devices that could help to contain and control the underwater leak."
Reader freddled points out a story at the Guardian that illustrates how the location of an oil leak is frequently the primary factor in its perceived importance.

"We've done a number of tarballs from Florida, Key West, Miami and so forth, none of which so far have matched the Deepwater Horizon," Gronlund said. "The tarballs that have been found on the beach in Florida are fuel oil."

Do you know what the amount of pressure was from the leak when BP's 3 failsafe's failed? 20k+ psi. The NOAA has that info; at least they did yesterday.
Crude is extracted at +/-1,500 psi, so they were drilling deep enough to hit magma pockets (I forget the proper nomenclature for those types of pockets).
Only Russia has successfully drilled that deep...but they weren't dumb enough to try that kind of depth under the pressure and weight of the freakin' ocean.
20,000+ psi will destroy anything man can make to "plug" the leak. Is our only option nuking it?
If so, even if they do angle drill and drop a nuke, what if it cracks the strata further?
IMHO this will help to shuttle in that BS carbon tax. The longer the leak remains, the more damage, the more "reason" for the aforementioned tax. ...But, of course, this is conspiracy stuff. :)

Any chance to expose the pillaging of Africa is a good thing IMHO. Such a tragedy, does anyone care? Not many where I live. Now I know that not everyone can account for what happens on the other side of the world, but I mention the Niger Delta, the DRC, the current state of Somalia and their civil war, Sudan, Egypt's relationship with Israel, anything from Africa.. and watch the eyes glaze over. I usually just take it as a chance to tell someone, an opportunity. If we ever want to be a truly global community then we need to know what is going on in that community. Heads in the sand cause future conflict.

Only a 1/4 is oil free....at the moment. I thought I read or heard somewhere that they were worried about the oil slicks/spill getting caught in some water flow thing and coming around the coast of Florida and up the Eastern Sea Board, not to mention every other country and island near there. So it may only be a limited amount of time that the beaches are clean and able to be enjoyed before most of Florida and parts of the Eastern Sea Board are a complete mess, let alone all of the Gulf of Mexico areas. Time will tell for sure.

You do remember that the flaming oil fields in Iraq were successfully put out by explosives, right? Detonating an explosive near the well could potentially close the breach without introducing it to catching fire or exploding. Given the properties of underwater/underground explosives, you could also drill a hole nearby and drop some explosives in there to seal off a long stretch of the well.
At least, in my head that makes sense.

True about valves being designed for 20 K psi being available.
However there are all the other aspects of the architecture of the systems down there that have to deal with 20 K psi. So many other bits of hardware have to be able to handle these pressures too.
Together they make for a very risky architecture because when something goes wrong we are at natures mercy.
Lets take an look at this another way. When we design an aeroplane we design in a Safety Factor. That means that everything is over designed to whatever the "Safety Factor" requires.
The engineering safety factor is determined by the consequences of a failure. For an aeroplane we design for a safety factor 1.5 . So everything structural is designed over by 1.5 times because if the wing fails it will likely kill 300 people.
See the Nasa article about it as it shows that safety factors are commutative for all the hardware combined.
http://blogs.nasa.gov/cm/blog/waynehalesblog/posts/post_1229459081779.html [nasa.gov]
For an oil well we should probably have a much much safety factor than just 1. So at 20 K SI, the equipment should be designed to handle at least a safety factor of 2, and so hence be designed for a 40 K psi.
Frustratingly because the damages claimable is limited to 75 million USD; and there is a self monitoring policy that wont design the hardware properly.
For aeroplane makers, there is no statutory limit on the damages, and they are heavily monitored throughout the lifecyle of manufacturer and usage.
As we are seeing the consequences of a failure of the oil well are likely to ultimately kill more than 300 people when you factor in the laws of cause and effect.
But humans that see it immediately; when an aeroplane crashes the laws of cause and effect are right in our faces, but when an oil well leaks if is less apparent to us immediately.
Its a shame that the industry has been allowed to get away with this. Energy policy is screwed up. We want oil, and so we let them get away with low safety because we dont want to scare away investment. ...
How crazy can it get
