Title: Advisory from the Office of Conservation
Source: Assumption Parish Police Jury
Date: April 21, 2013
h/t Anonymous tip

The Office of Conservation, in consultation with Assumption Parish Incident Command, is advising the public that the Oxy 3/sinkhole monitoring alert status has been raised to Code 3 – requiring all work inside and around the sinkhole to cease until further notice. Per Dr. Stephen Horton with USGS, seismic monitoring detected several instances of subsurface activity in the area around the sinkhole and Oxy 3 area below the sinkhole, at an estimated rate of more than 10 VLPs (Very Long Profile seismic signals, often indicative of gas or fluid movement) in the early hours of Sunday morning, and personnel near the site have observed surface movement on the western side of the sinkhole area. The seismic activity is limited to the Oxy 3/sinkhole area, showing no indication of impact to the Oxy 1 area. Monitoring is constantly ongoing in the area and Conservation will advise the public of significant changes in subsurface conditions.

    I have a feeling a volcano is going to surface somewhere in LA. Maybe the ancient one is ready to brew.

A strong one in Mehico this morning, and previously Italy, Algeria and mid-atlantic – so the Bayou is taking the weight of the planet prior to this 3 eclipse month.

    3D Results

    http://dnr.louisiana.gov/assets/OC/BC_All_Updates/Plans_Reports/BayouCorne.T5.Seismic.Results.0420.2013.pdf

    Bayou Corne 3D – 2013 Summary of Key Findings

    •Excellent seismic images provided by new 3D are much better than 2007 Legend seismic data
    •OG 3 collapse zone limited to small area at depth and small vertical riser along outside of salt face
    •No evidence of void spaces below sinkhole including any area near the base of OG 3 cavern
    •No evidence for large gas pockets below sinkhole including any area near the base of OG 3 cavern
    •Sinkhole fill disturbed area limited to depth of approximately 400 ft., is contained within berm, and remains far south of Hwy 70 and Bayou Corne
    •Small amount of residual Big Hum hydrocarbons near the Hooker # 1, serial # 20913, appears to have been liberated and virtually gone in recent survey
    •No evidence of multiple hydrocarbon zones as possible supply to sinkhole and MRAA
    •Radial faults appear in the same position as Legend data
    •No change in the competency of the sub-surface strata in the area except around sinkhole
    •Confirmation of at least 150 ft (+/- 75 ft) of salt between OG 1 cavern and edge of salt
    •Napoleonville Dome’s western edge of salt in same location as 2007 Legend survey – stable with no movement
    •Additional processing and refinement needed on MRAA images due to shallow depth

    So they say there are no voids…great.

      That is Texas Brines report.

      Here is what DNR says…

      "The Office of Conservation and its contracted experts have begun review of the report and interpretation initially provided. Conservation staff considers the report, and the assertions of Texas Brine and its consultant on that report, to be preliminary only at this point, pending independent verification and analysis by Conservation’s consultants."

        I'm seeing some juicy-looking drilling targets and plan on setting up a penny-stock E&P company out of Houston. Who wants to sell their mineral rights? I want to lock up the drill rigs and well finishing services as soon as possible.

        Just kidding.

        I'm assuming this is relatively good news for those of you that want to stay, right rainbow? Depending on Conservation's assessment, it looks like it could be (relatively) safe to do so as long as Texas Brine keeps an eye on migrating gas. Maybe this works against people that want to leave and get bought out.

        What's the word down there so far from the locals? Anyone change their minds either way about leaving or staying?

          Paveway….based on what I understand of that report, I take absolutely no comfort in it. Mainly the missing voids.

          Adding these statements culled from some of the slides:

          -New data shows layers of sediment going across the area. There are no voids, or large new gas pockets**

          -The new 3d seismic shows the edge of the salt to be 150-175 feet away from the cavern top of the OG 1. With a current uncertainty of 75 feet.

          -This map shows the structure of the MRAA. The area under Bayou Corne is un-imaged due to the town.
          …..

          I have these questions:

          My first question is, how can there be no voids with all the material that went in to the cavern that's way more than the sinkhole volume? WHERE ARE THE VOIDS?

          Second question is if the Big Hum is dried up, and no evidence of multiple hydrocarbon zones shown, then WHERE is the gas and oil coming from and why isn't the 3D showing it?

          Third….DID THEY cover a large enough area with the 3D? I say no. I'm not sure how far east they went, but what's to say the voids aren't under the Crosstex property?

          Fourth….if there are no large gas pockets below sinkhole, then what is all the "burping" about? And what about what Dr Hecox described aslarge volumes of gas coming up but being broken up by the sand and gravel? Our "lucky break"?

          Fifth….why was the MRAA under Bayou Corne not imaged?

          Sixth…what does "no new gas pockets" mean when we've been told there is a solid layer of gas under us for 2…

              Had very similar thoughts.. especially the plus or minus 75 feet when you are touting 150 ft as the distance??? Not the least bit reassuring as to the accuracy and caliber of the 3-D test.. which, as I recall was not the test that DNR wanted initially.. Didn't they want a much more intensive test that was significantly more expensive? ..until Texas Brine sued them? ..seems like I remember something like that.. This initial report sounds like a bunch of happy horseshit.

                another recollection.. didn't they say, once upon a time, most definitely there was no signature for big Hum… and yet, now they say "Small amount of residual Big Hum hydrocarbons near the Hooker # 1, serial # 20913, appears to have been liberated and virtually gone in recent survey.." hmmm..

                  That is correct Cataclysmic. In fact, we were told the Big hum was NOT the source.

                  Dr Hecox @ 14:26. Fingerprint back. Big Hum NOT the source.

                  No wonder people are so distrustful. It is. It isn't. It was, but it's not now. It wasn't, but is now. Never was. Always was. WTH are we supposed to believe any more?

                  Don Marlin, who will be reading the 3D for LDNR has stated that there are as many as 8 sources. The 3D shows no sources. So he has his work cut out to prove his theory.

                That is also correct. DNR wanted two 6000 foot wells drilled. Tb said that wasn't safe. DNR didn't stick to their guns and crawfished.

            "…WHERE ARE THE VOIDS?…"

            There might be billions of them riddling the collapsed zone debris – they're called bubbles. I'm surprised Hecox hasn't pointed this out, but then again they ignored him and the other scientist when TB lawyers showed up.

            There is no 3D imaging on earth that is going to show a quarter inch bubble of methane 4000 ft. down. Seismic profiling has it's limits. The two 6000 ft. holes they asked for were so they could get a better idea of the slop in the cavern and collapse zone including some idea of density. Maybe it's not a spongy mass of highly-compressed methane and dirt.

            The only thing TB's 3D work accomplished is to show that there are no huge, sharp-edged caverns of methane (voids) down there. The LDNR scientists are not going to be able to say much more than that with the same data. Ask Hecox how much methane could still be squished out of that much unconsolidated sediment.

            They have to figure out a way to sample or measure the stuff down there directly, which means some kind of drilling. I don't even know if that's possible.

            They're never going to know about deeper pockets underneath Bayou Corne because they're never going to drill there.

            Expect nothing from the state besides hot air.

    I have been hoping to hear that they see the problems, and now know what to do to fix it, but it may take 1, 3, 5 years, or, they see the problems, and yes, everyone needs to be bought out because it can never be fixed.

    I have never been afraid of the sinkhole, but the gas, and the voids. Enough debris to fill a cavern the size of 2 Empire State buildings has to have left a void somewhere. And despite the 3D, we still don't have answers on how long it will take to remove all the gas, yet now they say they see no sources,when 2 weeks ago we were told that yes, the gas is being removed,but the problem is it is coing in just as fast from "wherever".

      Eh….scratch everything I said. Word is from our Tennessee Expert that the 3D is "fake". A "fraud". That this one was just "a test" to see how us dumb cajuns would react.

      The REAL 3D is expected to surface at any moment, as "they" have been WARNED for the last time. Stay tuned!

        Huh? I'm just getting back to this thread now – I've been spending way too much time combing through peon-worthy scraps of information (truth, lies, con jobs, misc. stupidity – mine, etc.) on Boston.

        Tennessee Expert? I'm not sure who you mean here, but I'll go out on a limb and guess that you're being facetious.

        I expected Texas Brine to produce a half-assed liability-limiting 3D survey and it looks like they delivered. No doubt they haven't paid Louisiana taxpayers back a dime owed to the state either.

        The best course of action now is to have Louisiana's blow-hard Attorney General mistakenly sell Texas Brine's current debt to one of those cheap collection agencies (in Texas) for pennies on the dollar. Let the collection agency hound Texas Brine Houston execs at home, church and strip clubs 24×7 (and every other oil exec they've ever know, slept with or did other oily business with).

        After about six months, the LA AG can apologize profusely to Texas Brine about the bureaucratic mistake (blame some clerk) and then assure them that no further collection attempts will be made until the matter is decided legally and properly in the courts.

        And then transfer the debt to two different and even *more* aggressive, slimy collection outfits. OOoops!

    Nobody's buying Texas Brine's version of the 3D. They are playing it down but it's backfiring because it's bringing up a lot more questions than it's giving answers. It was a know fact that there were no promises from the beginning that the 3D would show anything of any consequence. It was the hope of a lot of people that it would set the record straight and we all know it hasn't. We just need to wait until it's looked at independently and that's when the tale will be told. There's no evacuation order lifted because Texas Brine says every things great. That I can promise.

      Your addressing the thought I was having. I haven't been able to sit down and scrutinize the image which was released but after reading the report which was linked I was trying to understand if they were saying the cavern filled with sediment but is still somewhat of a cavern with salt between it and the shale. I only read the file once so I did not digest it well. I was left with the sentiment that it had magically fixed itself and brine production could resume in #3 soon, lol.

      As far as the source of the gas, faults, lots of gas, Hmm, wonder if GOM methane is in play here? Again it isn't ruled out and until they can produce a piano fingerprint result compared to an identifiable source or sources I don't think the possibility should be dismissed as easily as I have seen it done in the past.

      "There's no evacuation order lifted because Texas Brine says every things great. That I can promise."

      Sadly, you are in noposition topromise us anything. You don't have the knowledge, or the authority, regardless of what who is telling you.

      Texas Brine is not saying everything is great. They are saying two very important things. One….that there are no voids.And two, that the western edge of the salt dome is stable and safe. that is 2 out of the 3 key factors that determine if the evacuation order is lifted, and people are not only allowed back home, but told it's safe.

      The voids can't be hiding. if they are not there, then they are not there,and LDNR can't draw them in to be able to say they are there. If DNRS consultant, Don martin also finds no voids, and that the western edge of the dome is indeed safe, then it doesn't matter what we, the people think. It then goes to the Blue ribbon Commission, and they go by the results and interpretations given to them.

        What? Not sure what you are talking about, did I promise to promise you something?

        "people are not only allowed back home"

        I don't see anyone stopping the residents from returning home as it is. What do you mean?

        "The voids can't be hiding. if they are not there, then they are not there,and LDNR can't draw them in to be able to say they are there."

        I disagree with your opinion. With a level of error +/- 75 feet It seems they could hide. Also as this image is developed from over a thousand energy sources which were taken over time, I would expect distortion of any details where movement of the soil in the collapse zone was active during the seismic data collection. That's like taking a picture of something moving very fast, say a car at highway speed, with a long exposure time on a camera. All you will see is possibly a blur. I think this "static" in the collapse zone could hide voids. Here today, gone tomorrow sort of thing.

          The amount of debris that had filled a cavern the size of 2 Empire State Buildings would account for a void slightly larger than 75 feet area, and not as easy to be missed, even with distortion or time lapse. My question is again, where ARE the voids, but if DNRs reading also says no voids….then what?

          No, you didn't make any promises that i recall.

            "a void slightly larger than 75 feet area,"

            Singular

            "where ARE the voids"

            Plural

            Many small voids which change in size and location with each shift of the soils may not show up. I would expect for any Large voids to show up but again you are dealing with a model which was created over a period of time when we know activities were suspended due to subsurface movement.

              Void/Voids/Singular/Plural. Semantics matter not to me. The point of my post is that if Don Marlin and Dr Hecox and LDNR don't believe they can be being missed, or are hidden, then that is what the Blue Ribbon Com. will base part of their decision regarding returning safely on.

              I for one hope the report IS accurate, but I would like a convincing, unanimously agreed upon answer as to where all that cavern fill came from since no other sinkholes have developed.

                I think this is more than semantics. My point is that if it was a big void or even a few big voids, they may be able to identify them. If it is many tiny voids they will need a magnifying glass. Like the difference between a bucket with a basket ball in it or the same bucket full of sand or gravel. You can see the voids easily around the basketball but not so easily through all of the gravel.

                I didn't expect to see any large voids as I would expect they would be very short lived with all of the seismicity in the area. I was wondering what the voids would look like if they were filled with brine or some other fluid? Would they show up as the same texture as salt? Not directed towards you, but just a general ponderance.

                Like you and many others I am trying to figure out where the missing volumes are. I guess it is possible that early reports of the bottom of the cavern rising were more literal than we took them to be. If the salt did push up from below then I would expect unstable conditions for a longer period as deeper geology redistributes the stresses.

                Also, I understand earlier I mistook your first response as being directed towards me, I apologize. Thanks for straightening me back out and thanks for the video journalism!

                  Thanks for the apology 16p.

                  I see what you are saying. Guess I never considered it being a bunch of small voids, but several large ones. We are talking at this point of almost 4 million cubic feet of sediment, and I would think enough small voids needed to account for that kind of space would essentially act as one large one at some point with the instability they would create.
