Parish Blog Update(s) from the Office of Conservation

Up to Code 3 … MICRO-quakes(!) are they nuts??

AND they say


Assumption Parish Police Jury

Bayou Corne/Grand Bayou Response Activity

Monday, Oct. 21 work-

Sinkhole Activity Code 2 – indicating no work is allowed directly on sinkhole, elevated due to seismic monitoring indicating trend of increased MEQ (micro-earthquake) activity near sinkhole/Oxy 3 in the past few days 

Sub-slab Sampling and Ventilation

– Conducting ventilation system inspections

– Conducting bi-weekly in-home air monitoring in Texas Brine-acquired houses


– Monitoring pump drawdown tests of OGRW 1 (Oxy 2 well pad)

– Continuing pump test on ORWs 39 and 40 (north of containment berm)

– Installing gas collection lines for ORWs 52 and 53 (west of Bayou Corne, south of La 70)

– Continuing running and evaluating DPVE 47 (west of containment berm)  

Containment Berm/Roads/Sinkhole

– Stockpiling limestone on site for potential containment berm needs

– Setting new reflectors around sinkhole

– Surveying DPVE 47 settlement plates

– Preparing for pressure reduction operations in Oxy 3A…

    • I KNOW-w-w!!
      That’s why I keep putting CODE 1 and 2 in big block letters! It should be CODE 4 (or 5 or 6!!) ….

  1. Few questions. Sorry, I haven’t been keeping up with thoroughly reading the parish updates. Am too sleepy to backtrack right now.

    Isn’t there an Oxy 1 storage cavern that is north of Oxy 3? Wasn’t it also brined too close to edge of dome? If I’m remembering that correctly, why isn’t there a monitor there anymore? I would have to go back to older map but thought I remembered a monitor there.

    And, why did they remove the monitor at the Crosstex storage cavern? Looks like they moved it to the Chevron cavern site. There never was one at the Chevron cavern before. Does this mean that there are issues at the Crosstex cavern?

    What do they mean by “Preparing for pressure reduction operations in Oxy 3A? Not technically literate in this well business.

    BTW, the ownership trails in the industry looks to me just as much a maze as the LA pipeline maps! Miserable on my poor brain trying to keep up with who owns what or who….Same with keeping well nos., monitors, geos, etc all straight in my head!!

    Also, don’t think I understood Freedomrox. Was he saying the marker in Pierre Part was a subsidence monument; and not a monitor?

    How’s a person supposed to keep up with all of this??? 😦

    • someone got the D-Con out!
      =whew= now we have to wait til night to see what’s happening since APPJ always allows work during their Code X-Y-Z.

      • Ever seen a siphon hose? Imagine two 5 gallon gas containers, and run a hose over to the first one and put a T in the hose, and small hose into the first can, then run the straight hose into the second can….squeeze the bulb and it will create suction from the first can, then when the level of gas is lower in the first can than the second one, then you will see that the second can drains over into the first can… Oxy 3A is the siphon pump, the Sinkhole is the gravity fed first can, and The lower formations are the second can, all being controlled by the amount of pressure, (When you squeeze the bulb), and de-pressurizing (when you let go of the bulb)…this whole system works the same way. Sometimes the Sinkhole is Can 1, and sometimes it is can 2…they interchange depending upon which has the most pressure built up, when Oxy 3A is depressurizedas to which one it will be Can 1 or 2. Formations below are either can 1 or can 2, again depending upon whichever has the most amount of pressure at the time built up. Now you know how the whole system works. If Oxy 3A is not completely destroyed, and the small cone at 1000 ft to 1500 ft. is not cemented in…then Nature will never take its course. Oxy 3A prevents Nature from resolving this and LDNR and the scientists all know this…They are playing with it to see what they influence. Scientifically, I can understand the fascination, but as a human being, I cannot justify the costs to the environment or people

      • freedomrox
        Is that how a ram pump works ?
        The device uses the water hammer effect to develop pressure that allows a portion of the input water that powers the pump to be lifted to a point higher than where the water originally started.

  2. Freedom’s explanation is a little complicated for me. I’m not familiar with siphons, etc. But, I think I’m getting it. As slough-ins occur, the weight of the sediments in the sinkhole increases; pushes more sediment into the cavern, which raises the contents in the cavern. The natural cavern shrinkage (creep) over time that is caused from the weight of the salt body bearing down on the cavern causes enough pressure to build up to push the cavern contents down. A couple of more slough-ins and the weight increases…or the pressure from outside the cavern increases and if they release the pressure inside the cavern by opening the well to the atmosphere, it would allow the whole process to start again. There would have to be multiple cycles of this process before the cavern would be filled. If my understanding of this is correct 😉

  3. Fascinating stuff! Wish I would have had better science teachers when I was a child. Girls weren’t focused on much in math and science back then…at least not in my schools. I didn’t think I could understand any of it until I began trying to teach my own daughters. I realized I could “get it” if it were presented a little slower and with analogies I was familiar with. Anyway, things are much different now 🙂

  4. I like FR’s description, it ain’t happens yet though, From the latest update
    “- Preparing for pressure reduction operations in Oxy 3A (working from Oxy 9 pad), estimate moving equipment in Monday, Oct. 28, and beginning pressure reduction operation Wednesday, Oct. 30”

    I’m guessing flaring may be involved as well. Will be looking very closely at the Heli’s on Wednesday as expecting this to show up BIG TIME.
