    How far is the "sinkhole" from the caverns containing butane (was 1000 ft. in August) now?

    Also, I believe there were caverns containing acetone? And how many of the caverns contain nuclear waste? Do they all contain nuclear waste, by-products of fracking, et al? Or just certain ones? What are current H2S levels, a highly flammable, ground hugging gas? A week ago, or so, an ene story said the area has now edged into "explosive" potential. Particularly with the "coincidental" chemical plant explosions, at least one of the crisscrossing oil pipelines in the area exploding, and the real possibility that the "Flash" theory is true, have potentials been revisited? What is being done to minimize a catastrophic, mega-explosion event? Would the oil pipelines not be involved as well, since one has literally exploded out of the ground? Would not the nuclear plant within this involved area be at risk? Shouldn't it be shut down until further notice? Is there more FEMA or military presence in the area? Why do we here, who know this is a bigger problem than a single "sinkhole," continue to not connect the dots? Why do we continue to think this is a problem for only the Bayou Corne community and not the entire region (remember Charles's report of what he thinks is methane bubbling in a New Orleans suburb's streets?) and even possibly all Gulf states since a mega explosion involving pipelines, potentially explosive cavern contents, and NPP would probably cause mega methane/H2S venting and jet stream radiation?

    The butane in the salt domes won't explode because a lack of oxygen. Butane must be mixed with oxygen within certain ratio ranges for there to be either combustion or explosion. Oxygen can only exist in the caverns if it is forcibly pumped there, because of the pressures involved at these depths, and as dense as some of these companies are, they're not going to do something that stupid.

    Butane will not reach the surface from the caverns on its own. It is in liquid form in the caverns and remains liquid because of the pressure at the depths where it is stored. Something heavier than liquid butane must be injected into the cavern for the butane to rise to the surface.

    All of the explosions take place at the surface, and in the open they are methane (natural gas), not butane. Butane can explode in a pipeline moving it, if there is a leak in the pipeline that allows oxygen to mix with it. Usually this occurs when butane leaks out, explodes, causing a large break in the pipeline, which results in a second larger explosion.

    So the massive scale explosions talked about by some are just speculation based on inaccurate suppositions. Yes, local explosions are possible, but gas explosions that will wipe the state of Louisiana off the map are pure fiction.

      salt cavern explosions…true that oxygen wont easily get in nor butane out.

      (from ENEnews); In 2001 large surface explosions occurred when propane had escaped through a failed well casing tied to the Yaggy field salt storage cavern seven miles away in Tulsa, Okla.

      The propane moved through the underground Milan Limestone formation, which tilted upward from the cavern toward Hutchinson, exploding in an old well, causing 100 fr high geysers.

      Another explosion in Texas exploded with the force of a three kiloton bomb, registering 4 on the Richter scale.

      " In 2005, 29 salt storage caverns were registered with the Federal Energy Regulatory Commission. 1 out of 3 of those had catastrophic accidents."

      So of the untold number of unanticipated possible events, gas could migrate for miles to a salt mine where there is air. Lake Peigneur salt mine is the dramatic example of accident. Is it out of the question? What if there were a meteor strike? While very unlikely, a huge quantity of gas could be liberated

      Yes, what if's are never ending, and are nothing without scientific weight attached. Meanwhile, engineers are doing their best to assure nothing bad happens.

      The pressure is hydrostatic, and would not occur toward the top of liquid gas storage, unless the space above were pressurized.

    Just fishing here, with no formulated opinion…what if H2S blows cracks in the cap? Would oxygen not "leach" into the infrastructure? Are there pipes leading to the formerly producing, adjacent oil extraction well? If they were corroded by H2S, could oxygen reach depths? You are saying oxygen would have to be pumped at pressure under those circumstances? How did oxygen get into the buried pipeline that exploded a couple of days ago?

  • Cataclysmic Cataclysmic

    so, continuing on the fishing expedition.. what would happen if the salt dome continues to collapse from the direction of the sinkhole, and the cavern with the butane in it, starts to collapse, or lose it's integrity, cracks form, allowing the liquid butane to mix with the liquid sinkhole slurry, eventually finding it's way up to the surface?

    I tell ya the sinkhole has to widen out until the underlying conditions can support the sidewalls. If it can't find supporting sidewalls walls because the void in the blown out cavern is to deep then the bigger the sinkhole must become as movements will be ongoing as sand and water and oil and rock and salts shift around.

    If they haven't emptied the intact but threaten caverns by now or as needed then a bunch of idiots are running the show.

    Any radioactive sludge in only concentrations of materials removed as excesses during fracking like coal has concentrated sunlight. If they remove (pump) it out to another holding area, that is fine with me.

    Looks like new picture hints the sinkhole will grow towards the browning die off of trees.

      According to Rain's information, they have only drained 40% of the butane. Response to: "If they haven't emptied the intact but threatened caverns by now or as needed, then a bunch of idiots are running the show." At this point, we should be heavily into damage control. Whether they're idiots or not isn't really material anymore. This is home turf to us all…and possibly, this clathrate melt, or BP migration, or whatever is causing the entire region's subsidence and bubbling (which "they" must certainly know) has even more immediate consequences to the U.S. than many theorists here may now suppose. IMO, this isn't just a Bayou Corne issue. At all. Theories are now being replaced by hard facts, like chemical plants and buried pipelines blowing up for "unknown" reasons.

    Butane is stored under pressure which causes it to turn to liquid (like inside a Bic lighter). If it is under pressure, it doesn't need to be forced out by injection unless you wanted to purge the cavern after the initial emptying of butane.

    You also need ignition to cause butane to burn, high heat would do it. They could always do a controlled flare at the wellhead instead of allowing the butane to leak out which could create a huge mushroom fire ball depending on how much leaked out before finding a ignition source. Butane mixing with air only makes it more volatile if ignited. No air available to mix with, butane will produce carbon (black soot) when burning.

    The next thing you'll need to do is make your home physical appealing. Get rid of the clutter. Vacuum those carpets. Wash those windows. You want your living room to look like something out of an IKEA catalog.
