"All the actions and few tid bits of information all lead to one

Now you have some real data of how BP's actions are evidence of that, as well as some murky statement from "BP officials" confirming the same. "To those of us outside the real inside loop, yet still fairly knowledgeable, [the failure of Top Kill] was a major confirmation of what many feared. That the system below the sea floor has serious failures of varying magnitude in the complicated chain, and it is breaking down and it will continue to. "This down hole leak will undermine the foundation of the seabed in and around the well area. It also weakens the only thing holding up the massive Blow Out Preventer's immense bulk of 450 tons. In fact?...we are beginning to the results of the well's total integrity beginning to fail due to the undermining being caused by the leaking well bore. What eventually will happen is that the blow out preventer will literally tip over if they do not run supports to it as the currents push on it. I suspect they will run those supports as cables tied to anchors very soon, if they don't, they are inviting disaster that much sooner. "Eventually even that will be futile as the well casings cannot support the weight of the massive system above with out the cement bond to the earth and that bond is being eroded away. When enough is eroded away the casings will buckle and the BOP will collapse the well. If and when you begin to see oil and gas coming up around the well area from under the BOP? or the area around the well head connection and casing sinking more and more rapidly? ....it won't be too long after that the entire system fails. BP must be aware of this, they are mapping the sea floor sonically and that is not a mere exercise. Our Gov't must be well aware too, they just are not telling us. All of these things lead to only one place, a fully wide open well bore directly to the oil deposit...after that, it goes into the realm of "the worst things you can think of" The well may come completely apart as the inner liners fail. There is still a very long drill string in the well, that could literally come flying out...as I said...all the worst things you can think of are a possibility, but the very least damaging outcome as bad as it is, is that we are stuck with a wide open gusher blowing out 150,000 barrels a day of raw oil or more. http://motherjones.com/blue-marble/2...ow-unstoppable Best Regards Tom. --- news://freenews.netfront.net/ - complaints: --- |

I think that you are ignoring quite a few things. Typically wells that blow out around the casing, and there have been quite a number of them, do not "destroy the foundation" as you think. They simply blow out a fisher and vent. Secondly the "foundation" is in effect a tapered pile reaching something like 15,000 feet into the earth.

In addition BP is energetically drilling two relief wells which when completed will be used to relieve pressure in the hole and serve as a conduit for pumping cement into the faulty well to permanently seal it. To be frank the attempts that BP has made to date with the chambers to drop over the well head are probably greatly in response to political pressure as I'm fairly certain that no one in BP expected them to actually cure the problem and simply hoped that they might catch some of the oil and calm things down until they can get the permanent solution in place. And I don't know what you have been reading but I can tell you that guys in the drilling business are certainly circulating some pretty specific data on the BP drilling program, what were the original problems, what was done when they finished the well and what was going on when the well kicked. In fact I posted, or thought I did, a short description of the completion of the well and what the rig was doing. Probably written by someone who knew one of the BP drillers or engineers or had been on the rig about the time they completed the hole. Cheers, John D. Slocomb (jdslocombatgmail) |

Unfortunately however, as a nation we are now far beyond this specific incident/problem, namely a total lack of credibility/accountability/capability of either the Federal government or BP. The available information indicates BP was in a continual quest for immediate profits, continually "cut corners," and got caught (as always happens). FWIW -- This is not the first instance, but the third, after the major pipeline leaks in Alaska caused by a total lack of maintenance, and the explosion in the BP refinery in Texas City, Texas that killed 15 and maimed hundreds. [What happened to 3 strikes and your out?] http://en.wikipedia.org/wiki/Texas_C...nery_explosion http://en.wikipedia.org/wiki/BP http://www.msnbc.msn.com/id/11696601/ http://www.marke****ch.com/story/ala...-ok-2010-05-29 The secrecy surrounding the mitigation efforts and clean-up activities by BP, aided and abetted by the Federal government's no go/ no fly zones around the blow-out site, and attempts to keep people away from even the beaches can only result in the assumption that things are far worse than admitted. The refusal of the Federal government to use the proffered expertise and equipment from other oil producing countries and their prevention of the use of oil recovery barges indicates either serious "hidden agenda" problems or gross stupidity, neither of which can be tolerated in a modern society. IMNSHO the Federal government via the MMS shares accountability with BP for this mess in that the oil companies were allowed entirely too much scope and room to cut corners. Given the extremely serious potential, and now actual environmental impact, and high on-the-job danger levels [11 killed, more maimed], it would appear that the MMS should have been specifying what practices *MUST* be followed, what type approved equipment *MUST* be used, e.g. no jury-rigged blowout preventers, and what drilling practices, e.g. double wall well casing, cementing [verification] tests, *MUST* be used. Deep water drilling appears to offer much the same levels of risks and benefits as nuclear power and civil aviation, and there appears to be no logical or plausible justification that similar governmental oversight and "best practices" should not be imposed, backed by stiff civil and corporate/individual penalties. -- -- Unka George (George McDuffee) ...............................

Doomsday scenario. Or, or , or, , , , , that well reaches into the "mother pool" of oil underlying
the entire G.O.M. and it will continue to flow until the pool is depleted. Of course, by that time the economy of all the US coastal states will have been totally wrecked; with the nation's economy in ruins as well. We will have no fossil-fueled defenses to fight with and none of our allies will come to our aid.

Not so easy to do just that so deep in the ocean.
And I don't think the casing and drill stem will just pull out so easy. the broken and not functional (so we think) and only easy access point to the tube might be clamping down on the pipe and stem or just the pipe and if it releases - might open up even more. The crushing blow that didn't stem the flow might be 80% of the flow stopped or 20% stopped... And it isn't 'easy' to just take off. Otherwise it would have been blown off by the high pressure moving through various side pipes. Who really knows. Once release wells are cemented in - I rather expect a recovery attempt of that unit is under order. Why did it fail. It was the insurance policy in hardware that failed. Martin H.

For want of a nail... http://www.nytimes.com/2010/06/21/us...er=rss&emc=rss Failure of Rig’s Last Line of Defense Tied to Myriad Factors This article is by David Barstow, Laura Dodd, James Glanz, Stephanie Saul and Ian Urbina. snip They wondered if the blades had by chance closed uselessly on one of the nearly indestructible joints that connect drilling pipe — a significant bit of misfortune, given a decision years before to outfit the Deepwater Horizon’s blowout preventer with just one blind shear ram when other rigs were already beginning to use two of them to guard against just this possibility. snip As it turns out, records and interviews show, blind shear rams can be surprisingly vulnerable. There are many ways for them to fail, some unavoidable, some exacerbated by the stunning water depths at which oil companies have begun to explore. But they also can be rendered powerless by the failure of a single part, a point underscored in a confidential report that scrutinized the reliability of the Deepwater Horizon’s blowout preventer. The report, from 2000, concluded that the greatest vulnerability by far on the entire blowout preventer was one of the small shuttle valves leading to the blind shear ram. If this valve jammed or leaked, the report warned, the ram’s blades would not budge. snip Using the world’s most authoritative database of oil rig accidents, a Norwegian company, Det Norske Veritas, focused on some 15,000 wells drilled off North America and in the North Sea from 1980 to 2006. It found 11 cases where crews on deepwater rigs had lost control of their wells and then activated blowout preventers to prevent a spill. In only six of those cases were the wells brought under control, leading the researchers to conclude that in actual practice, blowout preventers used by deepwater rigs had a “failure” rate of 45 percent. snip Using the world’s most authoritative database of oil rig accidents, a Norwegian company, Det Norske Veritas, focused on some 15,000 wells drilled off North America and in the North Sea from 1980 to 2006.

In only six of those cases were the wells brought under control, leading the researchers to conclude that in actual practice, blowout preventers used by deepwater rigs had a “failure” rate of 45 percent. snip The consultants said the Deepwater Horizon’s blind shear ram was vulnerable to “single-point failure.” In other words, the breakdown of just one part could result in a catastrophic failure. The consultants focused on one of several T-shaped shuttle valves, which control the flow of pressurized hydraulic fluid that pushes the shear ram’s blades together. This particular valve has no backup, so if it gets stuck or leaks hydraulic fluid, disaster beckons. In fact, the consultants concluded that this one shuttle valve represented 56 percent of the blowout preventer’s “failure likelihood.” snip Yet in April, as BP prepared to seal the well for later production, the company took what numerous industry experts and fellow oil executives say were highly questionable shortcuts. These included using a well design that presented few barriers to high-pressure gas rising up; skipping a crucial $128,000 test of the quality of the cementing; and failing to install capping devices at the top of the well that could also have kept gas from lifting a critical seal. snip At 7:30 a.m., a submersible cut a firing pin on the blowout preventer, simulating the rig’s pulling free. This time, the blowout preventer shuddered, as if struggling to come back to life. “L.M.R.P. rocked & settled,” one note says, referring to the top half of the blowout preventer. But after a few moments, as oil continued to flow, it became clear that this, too, had failed. snip Finally, seven long days after the explosion, operators of the underwater robots managed to repair the leak on the blind shear ram and apply 5,000 pounds per square inch of hydraulic pressure on its blades. This was nearly double the pressure it typically takes to shear pipe. A BP report tersely described the results: “No indication of movement.” ============== -- -- Unka George (George McDuffee) ...............................
