Title: Public Briefing 5/1/13 – Part 5
Source: Assumption Parish
Date: May 1, 2013

Gary Hecox, CB&I hydrogeologist: The thermogenic gas from depth has moved upward and has displaced the shallow swamp gas.

So what we talked to you about last November as one of the concerns we had was the deep gas in the MRAA [Mississippi River Alluvial Aquifer] coming up and displacing the shallow gas […]

So unfortunately what we told you several months ago that may be happening in terms of the deep gas displacing the shallow swamp gas appears to be occurring. […]

At least some of the methane in the community that is being detected has moved its way up from depth and is now coming up in the shallow part of the system […]

Now we know at least one of the bubble sites has a direct connection to gas coming up through the disturbed rock zone into the aquifer and is coming up through the other bubble sites.

    what are the potential outcomes of this methane moving on up?

      It is bringing other gasses with it from the hydrocarbon formations. Benzine is typical but if you want better info look at the fingerprint analysis from some of the samples. Then just google the gasses to see the hazards they pose to people.

        16p How does the "fingerprint" of gasses sampled compare with the Macondo footprint of gasses? Is it time to answer this question, as well? (a question I have been asking since September.). Where is the Methane/Benzene/H2S ORIGINATING? Yes, it starts at 3400 feet in the immediate area of the salt dome now…where did it come FROM? How large is the area of bubbling? We've had reports from witnesses posting on ene that bubbling is almost all the way to Lake Peigneur. The MRAA connects to the streams and river systems, yes? Are pollutants detected? How far is the lateral "push" of the gasses? The good news is that so far, the gasses have been able to find gushing and not explosive release. The bad news is that they can't control the pressure in the salt dome, which I see as acting like a vent or chimney of concentrated pressure release. But as pressure builds, it will find release elsewhere or build up and explode out. So, no good news…because either way…if the gas busts out in gushing or if it explodes out, there is increased risk of Ignition. Whether this would ignite cavern stored flammables has been debated here because of oxygen needed to fuel the underground explosion…but it does seem that a "wick" of fire might make its way into the cavern. Otherwise, if or until it explodes, Rain's voice may continue to rasp and deepen, folks will have respiratory distress, cancers may have already started, and wildlife and food will be contaminated.

          I wish I had access to a fingerprint from the gaseous portion of the Macondo mix. All I have been able to locate was a fingerprint on a weathered/aged sample which was on coral. The state has access to both. I noticed that while they were dispelling alleged "rumors" they made no mention of the connection between the two.

          As far as the gasses origins, Part 11 made a glancing blow on that. I didn't take good notes there so sorry no time stamp or speaker's name. The guy said the VSP shows the hydrocarbon traps were gone in the area of the collapse. That only means they are not holding hydrocarbons in the formation. That does not say that hydrocarbons and/or water are not passing through the porous formations which are now in communication with the rubble chimney. The assumption that the source of hydrocarbons (both liquids and gasses) is exhausted as the speaker did, is not supported by the fact that the remaining unfilled portion of the cavern is rebuilding pressure. That is called contradictory information.

          The locals are trusting technicians who are this prejudiced? Show me how unbiased you are Hecox. Call that guy to task and make him stand up next meeting and do the "in true Bayou Corne fashion we were proven wrong again" dance. Hecox, you will enjoy it more from the stands I promise.

          thank you 16P and IRH. I was so busy before with nuc news/twitters wasn't paying too close attention w/the sinkhole science… seems there's still a few important pieces missing in this knowledge puzzle.

      Possible/likely exposive events, or..the poisonous gases such as the H2S..both events could be dangerous to health. Boy, is THAT (Dangerous to health ) an understatement. Anyone mention buy outs of property yet..or is Texas Brine running for the hills???? If you can see the posterior "cheeks" flapping in the wind.they are running way..if you see the other "cheeks" flapping,think of coverups/fake reporting. Plus, Ignoring of any and all health and environmental dangers to Bayou Corne..or the rest of the aquifer area. "What we(experts) warned about…"–is just covering up..again.unless they/Texas Brine takes ACTION and RESPONSIBILITY. Isn't it also the responsibility of State of LA/EPA to keep TB working and correcting the dangers–like a "watch dog?" Seems other organizations, non-government, do a much better job. Why not CUT EPA or State of LA budget and save a few taxpayer dollars??????

        Yeah, non-government, non-funded "organizations" should do everything, yes? Then we will be SURE to have nothing. You can just save your taxpayer dollars and be helpless all on your own. Look, if government has authority there, make them do the work!! Do you elect these people? Then make them accountable!!

    Yes..methane and oil coming up from..unknown depth.
    Surely… they have done sampling..someone knows..where the oil is coming from.

    I agree..James Hollen.
    My concern..as the subsurface destruction continues..the geological materials (methane/gas).. following the path of least resistance upward..will find less and less resistance through time.
    I suspect the situation will accelerate.

      My main concern is this gas being released violently vs. being released slowly like it is now. One of the wells is at 500 psi ? The biggest "IF" in the world is if this gas could be vented off slowly-that would be perfect, but that looks least likely as time goes by. If that gas was to be released all at once, the surrounding area would immediately collapse into a giant hole, would it not? Just wondering. I would NOT want to be anywhere near THAT! You would see that fireball in Canada!

          Right.What is being done at the sinkhole is a waste of time and money. That is not the problem, that is the "result" of the problem! That is what we can visually see but that is not what really is going on. You and I realize that, some people do not. (reminds me of that 500 lb. elephant in the room) LOL

            Yes..it's a waste of time and money..
            People,time,and money..better served..with compensating the people quickly.
            And getting ready to see how ..it 'runs'.
            Even moving'slowly'.. 2 years out..5 ten..50..this is going to be a mess.
            Explosive potential…forever.

            The only thing they are doing 'at' the sinkhole itself, is skimming and monitoring. The majority of the tremors are around the sinkhole and Oxy 3, which is very close to the sinkhole, and directly related.

            Compensating people quickly will do nothing to resolve the problem, or protect the environment.

            It'snot a well that has 500+ PSI pressure, but Oxy 3 salt cavern, and they stated at Weds meeting that there was very little gas left in the cavern. That is was filledwith debris with about 100 foot remaining at the top that is brine. As more debris comes in, the brine is finding it's way out. They think what little gas is in the cavern is coming in with the debris.

            They admit the pressure is uncontrolled, and they don't know why it's staying so pressurized, but should it 'blow it's top', it won't be a fireball event. All of this is explained in the community meeting videos.

              The pressure in the well… doesn't mean that much to me…and is not what I am referring to.
              I am referring to the pressure build up or release…the various sources of oil/methane are breached…as the 'disturbed'area continues to 'shift'.

                Correction..the cavern at 500 PSI.
                This represents levels now..not the potential…pressure that may present itself..in the area..

                  What do you think has been blowing through the 50 by 100 foot long chunks of the clay layer? You are right on with this. As long as it can flow freely it bubbles. When a slough in happens the hole gets plugged. Then pressure builds in the collapse zone, the loose geology shifts, a pathway opens for the gas and burp!

              As Heart of the rose stated, compensate the people and get them out of the area. I agree, that will not solve the problem, but it will remove innocent people from the area in question. All of this increased bubbling at the surface leads me to assume a lot of gas is moving upward via cracks in the earth. Something is going to have to "give". Increasing bubbling usually means decreasing integrity of the caverns in question. (In other words, you got a leak and its getting worse) !

              Rainbeaudais, I'm just trying to understand what, if it is just ONE thing, was the root cause of the salt dome problem.
              I visit this site almost daily, but may have missed it.

              I know you live near there and always give factual reports on what analyses are and have been done.

              Remembering…. even back before the cavern collapse, they were having approx 900 psi of nat gas pressure build up about every two weeks; which they (TB I presume) would be able to vent to atmosphere, and in a day or so the pressure would be reduced to "acceptable levels".
              1.) Was there an event which can be attributed to triggering this gas leak into the cavern?
              2.) Do we believe the gas bubbling up "from the deep" now is from the same source?

              TIA

                Hi gr81…

                "Rainbeaudais, I'm just trying to understand what, if it is just ONE thing, was the root cause of the salt dome problem."

                Mining of the cavern too close to the edge of the salt. The 3D tests done way back to determine where and how far to drill showed the dome to have an overhang at the top. Like the left side of a capitol T. It was believed that the entire edge of the salt extended the width of that overhang. It didn't. It only went out as far as the body of that T.

                The collapse of the sidewall of the cavern triggered many things, and one of them was yes, disturbance of one or more oil and gas formations.

                Yes, it is assumed the gas still surfacing is from the same source(s).

                That's the best way I know to explain it. I don't believe this was done out of greed, or evilness, or to depopulize the gulf coast. I believe it was due to incompetence, neglect and complacency of more than one party that triggered a disaster that none of the above would ever have wished for, or thought would happen. And I believe that the very people responsible for this, are doing everything in their power to right it.

    The Precautionary Principle..

    Here's how the Rio declaration, which the UK, with 171 other states, signed in 1992, defines it:

    "Where there are threats of serious or irreversible damage, lack of full scientific certainty shall not be used as a reason for postponing cost-effective measures to prevent environmental degradation."

    Stewards of the natural world do not understand the precautionary principle
