Title: Texas Brine: Sinkhole gas flow diminishing

[…] Scientists with the Louisiana Office of Conservation and its contracted agent, Shaw Environmental and Infrastructure, have suggested the cavern failure tapped an oil- and gas-bearing formation thousands of feet deep known as the “Big Hum.”

But officials are not able to say how much oil and gas is in the formation.

“Study is ongoing by Office of Conservation staff and Shaw E&I to determine the potential volume in place, but more work is needed to gather and analyze data to develop a useful estimate,” said Patrick Courreges, spokesman for the Louisiana Department of Natural Resources, of which the Office of Conservation is a part.

“Work is being conducted continually to get to the bottom of this situation,” Courreges said.

Officials have also not pinned down with certainty which formation or formations the gas and crude are coming from.

Courreges added the Office of Conservation and Shaw are analyzing the crude to determine the age of the formation or formations that are the source or sources of the oil and gas being stirred up by the sinkhole-forming events. […]

    Big Hum is a group of sand layers deposited by the Mississippi River eons ago. It is not a hydrocarbon *source* layer. Oil and gas were formed in deeper layers and migrated up to the Big Hum sands. Those sand layers are bent upwards by salt domes and create oil/gas traps next to them.

    The Big Hum sands are mostly filled with water in the deeper formations – the oil/gas floats on top of that water and will collect in the highest spots locally, like the ring around the Napoleonville Salt Dome.

    There is an enormous quantity of oil and gas trapped in spots throughout the Big Hum sands, but you can't drill one well and expect to suck oil from all of South Louisiana. It doesn't even work for the ring around Napoleonville. One well will only produce for a certain amount of time before the pressure drops too low to lift the oil *or* too much water comes up with the oil making it uneconomical to produce that well.

    The sinkhole could stop burping oil tomorrow, or turn into a flaming geyser for the next decade. There's really no way to tell other than identifying the source (Big Hum or whatever) and drilling into that to monitor pressure.

      They are flat out lying if they are saying they don't know the source. It would be more accurate to say they didn't know what was mixing with at least one known source, which they will not name.
      Anyone got info on the control used for this spectrograph? (page 2 through 6)

      http://www.deq.louisiana.gov/portal/Portals/0/BayouCorne/20144605FINGERPRINT_fr.pdf

      From page 2: "The combined chromatograms in Diagram 1 are the comparison of samples 041-092212-01, 041-092212-02
      and the Standard from the Alkylated PAH analysis. Samples 041-092212-01 and 041-092212-02 have the
      same chemical pattern and are contaminated with the same organic compounds. They contain components of
      the comparison standard but are also contaminated with another lighter hydrocarbon component that is not
      in the comparison standard. Samples 041-092212-01 and 041-092212-02 have a number of compounds
      present at retention time 4 to 7 minutes but the comparison standard does not, "

      They know what the control sample was which was analyzed months ago (9/22/12). I wish someone in the parish would just print off a copy and take it with them to the next meeting. Then we would know what one of the sources is, or know that they are withholding important information if they will not disclose it.

    The officials..don't know the origin..or the outcome..but things are under control?
    Is this the part where we throw up our hands..or is this is when.. the officials are told..get the hell back to the sinkhole and figure it out?

    Again!!! Low levels of H2S coming from the cavern well. "Texas Brine has reported to parish officials low levels of H2S coming from the cavern well. DNR, Shaw representatives, and the OEP Director went to the site to validate Texas Brine’s reading and found no levels of H2S on their monitors. Readings will be repeated in the morning when Texas Brine flows the cavern well again. Should H2S be present at that time, appropriate actions will be taken. We will keep you updated.

    Please note that no H2S readings were picked up on the community air monitors."

    "Based on the sinkhole water level transducer, the “burp” that occurred on 1/20/2012 @2245 moved approximately
    15,000 ft3 of water (100,000 gal; 2,700 bbls). This was 0.04 foot instantaneous water level change over the area of
    the sinkhole of about 8 acres. The 0.08 foot change on 11/27/12 moved approximately 30,000 ft3 of water (200,000
    gal; 5,400 bbls). The event on 11/20/12 was preceded by a rapid water level rise of approximately 0.01 foot when a
    gas bubble reached the surface, though the gas dissipated upon reaching surface. A similar rise was not recorded for
    the 11/27/12 seismic event . Both water level changes were recorded by the water level transducer in the one
    inclinometer equipped with such a transducer."

    This sinkhole is a scary situation here in the Louisiana area. I will be in the sinkhole (Bayou Corne) area again soon. I will be capturing some HD footage of the sinkhole. I am also reporting on this News story for a radio show out of Fresno, California. I will update you on this important News Story by providing you with NEW HD videos soon. As you can see this sinkhole is ONLY 60 miles from the Waterford 3 Nuclear Power Plant here in Louisiana!

    • markww markww

      Thought if the sinkhole blows the Butane well to the right of the water,which there re indications from the helicorders, we could be facing a nuclear type explosion see video from Dutchsinse below. as a fire captain this could totally wipe out the nuclear plant and start another Fukushima in Louisiana.

      http://www.examiner.com/article/sinkhole-h-bomb-explosion-equivalent-bayou-corne-possible

      I also believe if by the map 50 miles goes up can you imagine the force when storage tank farms refineries and underground tanks at gas stations all go up it would be a biblical fireball and kill thousands of people by incineration.

        Gee, Markww, what a cheery thought. Just teasing. Sometimes you just gotta let the doom and gloom go, when there just isn't a thing we can do about it.

        People will do what people will do and Homeland Security ignores us all, until they need a convenient domestic terrorist.

      • FREEDOMROX

        Markww, may I ask a question? If you got a call from a residence that reported a Natural Gas Leak sixteen feet down and spewing at 5 PSI…what would be your professional response?

        • rainbeaudais rainbeaudais

          Good Morning Freedom…

          I have it on video when the gas came up, (working on the video), and it didn't come spewing up. In fact, the guy squatted there for several minutes holding the gauge over the well waiting for the gauge to pick up a reading.

          So my take on it was although zero of course would be normal, 5 PSI isn't all that bad. But remember, this was a very shallow reading, and had they gone deeper, the pressures would have increased.

  • markww markww

    FreedomRox this is bigger than just one person what if is hard when there is nothing to go by.

    The animal was let out of the bag. This is going to happen everywhere.I know if things pop I am going to the balconies escarpment in Texas where it will be the new Gulf Coast. One possibility is freeze the methane, with liquid Nitrogen. One theory I had was to drill to the said of the sinkhole put nitrogen layers and try to freeze the Hum and then layer the side with a aggregate. Maybe if enough drills freeze the animal and stop the side ways drilling some of this may stop but the underground explosions up and down the new Madrid fault and Texas and AZ could be a vent system I know for a fact the Texas boom was felt 60 miles all directions. FREEDOM Rox i think everyone needs to try to come up with solutions no matter how dumb they may be they might work.

    Markww

    • @markwww : My solution is just a slight modification of the liquid nitrogen possibility… instead of filling the side with aggregate; fill it with politicians and oil & gas executives.

      What's a "helicorder"?

      • Cataclysmic Cataclysmic

        These displays digitally simulate actual seismograms that are routinely recorded at CERI. The seismograms show a record of how the ground moved at a particular seismograph station in the Southeastern U.S. during a 24-hour period. The seismogram is "read" like a book, from left to right and top to bottom (this is the direction that time increases). As with a book, the right end of any horizontal line "connects" with the left end of the line below it. The colors of the horizontal lines have no particular significance.

          wondering if these helicorders picked up Japan eq? can anybody do the time adjustment? between 2:30 and 4:30 cst or between 8:30 and 10:30 utc.. what time would that be in Japan?

    Unless I stand corrected.. the Big Hum..is at a lesser depth than the the caverns..the disturbance in the caverns is below it… it stands to reason that it would be involved.
    I also think there is another issue below the caverns going on..

      Thanks, Anne, for posts re fracking. I have concern that it's a 'sleeper'. In so many communities (globally even) it is welcomed as a needed economic boost.

      I'm puzzled alternative energy developments don't attract more interest among local citizens, local political/economic interests also. I can explain it to myself but it's still tough to watch fracking gallop forward when I imagine the same communities dealing with consequences.

    You guys seem to have a better handle on this than I do, but on a few occasions I'm reading info as to the wells 1500' east holding 1.5 mm bbls etc. This map is old ( does not even show actual sinkhole ), but zoom in & confirm if you can in real time what current net fill is on these guys. According to PDR there is POTENTIAL for up to 19 million barrels. Biggest capacity is Chevron #972568 alone at 15.51 bbls natgas.

    Louisiana sinkhole up close in HD! December 7, 2012 (TODAY) HIGH DEFINITION footage! NOTE: A few people (possibly multiple accounts don't want me to report this news story) Very aggressive individuals with some uknown agenda and or reason(s). They post harassing replies towards me and break the rules listed on this site. I inform my viewers that numerous government agencies are working in the sinkhole area and they are helping people in the community! Not sure if the individuals harassing me have ties to certain organization(s) and or possibly work for the company involved in what has occured in the sinkhole area. Government reps are now monitoring some of the postings here. So if you see any derrogatory comments posted be aware of what is occurring. This is a video link directly related to the subject posted here (Louisiana sinkhole) NO spam! For those that are interested in what is occurring in the sinkhole area I am providing you up close HD footage! Thanks! http://youtu.be/iBDUNg_s5C0
