Title: Experts face challenges with sinkhole gas
Source: The Advocate
Author: By David J. Mitchell
Date: October 28, 2012

[...] state officials and their contractors have not struck paydirt and, as a result, face uncertainty about just how much gas is underground, authorities said. [...]

At high enough pressures, the fear is that the colorless and odorless gas could escape from an aquifer through solid earth, collect unseen and present an explosive risk, though those kinds of levels are not suspected, parish and state officials have said. [...]

“One of the problems doing this stuff real time — which this is real time — sometimes you reach a conclusion that subsequent data says, ‘No, you were wrong,’” [Shaw Environmental and Infrastructure geologist Gary Hecox] told the crowd of more than 100 people. He said that some days earlier, officials found they did not have high gas pressures in three Shaw vent wells and believed that was a good thing because that meant there was not a lot gas pressure underground.

“I am here tonight to tell you I was wrong on that because what we found subsequent to that, all the perforations in those wells are clogged up, so we were reading low pressure, but it didn’t mean anything because the perforations were clogged up,” Hecox said.

“So … that’s one of things that was not correct.” [...]

    Tired of "experts" assuming the best and reporting it, then realizing later they were wrong.

    Everything from natural disasters to the stock market to the economy is being fluffed by lies and half truths to convince the sheeple everything is wonderful.

    The blab blab continues, at least THIS geologist reported he was wrong..WHERE are the others?? And still no pressure readings, reports on crude oil fingerprint..is it ONE oil deposit/shale production..or many in this mess? Because nothing is being said..one might think someone has something to hide???

    Well My 2 cents worth, this man has been the only one that has even stepped up to the Plate. he has talked and he Is using knowledge that he has. Just like ANY EMERGENCY person, we do the best that we can do. THIS DISASTER has NO BLUE PRINTS so every step is going to be something new. No ONE knows what will be the end result some good some bad and some down right Devastating. I one will do the best I know and have made allot of possible theories. Give this Geologist credit He is doing the BEST HE KNOWS he is the only voice that has stepped up to the Plate, and no one, has anything to go by as to this ongoing problem.

      Markww, i completely agree with you. Everyone down there dealing with this sinkhole are operating on a set of beliefs that have all been taught and widely held as fact and what seemed to work for them up until now. People forget that the whole point of scientific inquiry should be that you change your belief as you get better information and insights. Hecox is taking responsibility full on and acting in everyone's best interest. I want to also thank you ham radio operators getting set up for the coming storm. Time that everyone started stepping up to the plate and becoming a little expert at something like volunteering in emergency preparedness, home food gardening, cleansing the body of toxins and radiation, helping wild or domestic animals survive these coming times, write their editorial page article, personally thank people who are doing their best….

    Markww I do understand your perspective but let's think of this one:

    A young vet, his young wife, and his small kid are about to have themselves blown the fuck up because no on can figure anything out.
    They are going endure a fiery explosion of an unprecedented magnitude. The flames will be so intense that the best anyone will be able to hope for is death by vaporization. Then apply that same fire storm all the way to every citizen in Baton Rouge, shutting down all hope for emergency vehicle access or citizen escape in any direction.

    Can you hear me now?

      That's why they evacuated the nearby residents and are constantly monitoring the air all around there for hydrocarbon concentrations. That's why they want to measure, vent and flare the two big pockets of methane they found under the observation wells. That's why they need to clean out the perforations in the observation wells before they do anything else.

      Why direct your anger at the guy hired six weeks ago to fix the problem? The DNR and Texas Brine have been there for twenty years guessing how far away Oxy #3 was from the edge of the salt.

        They did not evacuate enough people as you will soon see. Now I don't give a flying fuck who did it. I just want the men, women, and children who don't know that they have to get out to SURVIVE.

        What do you really want here since you're talking instead of alerting people to evacaute?

        I'd like to hear this.

          Because alerting people to evacuate has serious damn consequences – it's not my choice or your choice to make FOR them. Like anyone else, they want to know as much as they can about the risks and consider that against the consequences of leaving their homes.

          You're insisting that there is an immediate, lethal risk over a huge area but don't care to qualify that? Yeah, everyone knows the company and DNR will downplay the risk. I just don't see how that expected reaction translates directly into an imminent, high-probability threat for everyone a few miles away that demands evacuation.

          Kalidances, how many do you propose be evacuated? Where is the boundary? Should emergency managers consider the possibility of the Madrid fault cracking wide open? That alone will vastly increase the scope of this crisis.

          Where do all these people go and for how long? Nobody knows. If I had children or grandchildren anywhere near this mess I would find a way to get them far away, but that is easier said than done. If everyone they know lives in that area, who will take them in far from the only home they know? Do they live in their car for the next two weeks or the next two months or until the 12th of Never? Who will protect their home from vandals and thieves, especially if all their neighbors have fled as well?

          It's easy to talk about what should be done—and even easier AFTER the eventual outcome is known—but the residents of that entire region are in one big crapshoot and the house always wins!

    Yes at least this guy is trying to explain an event that no one has ever had to deal with. Yes, they have had salt domes fail but nothing like it's a new and special sinkhole, salt dome, lake of hazardous waste and an all and all nasty disaster.

    Any earthquake experts out there? I am kinda curious to know what goes on with the seismogram readings from the sinkhole, where it is blindingly obvious that the waves from the Canada quakes are making themselves felt there. Not just a little bit either, A LOT. No other quake I have seen caused this degree of wave activity at the hole. Does anybody know if there is some underground connection, some reason, that would shake this Louisiana swamp from a quake in Canada? Sorta thinking anything that would shake it like that has the potential to shake things loose in the sinkhole. Any ideas?

      vivvi, current earth movement studies do not accept connections between ground-shaking unless they actually share a fault line or tectonic plate subduction zone. I believe that continental subduction is a deeply flawed theory, and staying with it will never allow geologists to see earth movement as it really occurs. As long as extraction activities remained superficial, phenomenon remained localized and things could look stable. But, that is illusory in many ways. However, if you take the theory that the continents are deeply rooted to the magma core rather than floating bumper cars colliding into one another, then you start to get the connections and natural forces you are seeing. Trust you instincts on this. The current science is incorrect. There are other, more accurate models.

        I remember seeing some patterns caused by the Costa Rica quake a while back, but nothing like this. Even the 6.3 aftershock made a huge wavy pattern that lasted quite a while. I was curious whether the type of movement of the Canada quake was affecting some underlying geology that in turn is shaking the softer ground around the sinkhole. It is behaving as if it is waves in a bathtub, not solid shaking that stops when the jolt is over.

    if the cavern is just the right size to match the frequency of the canada quake, it's a tuned resonator.

    that's all.

    now, ringing a busted bell, is never a good idea :-(

    if you want to know what's going on, they need acoustic rigs to map the structures.

    they also need to drain the product out of this asap and try and flood it with water.

      markww, this looks like land fires with a southerly wind to me, or airborne vent releases from various wells, but, i can't make a better guess than that without more views and some idea if that is gaseous or liquid. I am assuming gaseous and above ground since the camera is capturing the image. Or, is this clip from an infrared satellite camera, in which case, maybe heated methane just under the surface? Liquids and gas can present similar flow patterns, but i would assume the methane would be meeting with impediments and soil resistance and we'd see more sideways spreading here and there, and less uniformity maybe? I'm going with air born smoke from field burning or precautionary burning off methane at wellheads, or methane gas venting as seen in infrared. That doesn't narrow it down much, does it? In Oregon, we are nearing field burning season for farmers who burn off the stubble from summer's crop before planting a ground cover such as clover or have created massive debris piles out of the decaying vegetation. The plumes look similar to the ones in this video. The farmers wait to burn until the winds are such that they will let the smoke plume rise and head away from population centers, and then they all set their fires on one or two days along the whole hundreds of miles of valley at once. Sometimes the winds drive the plumes to ground, in which case, highways close, the air is miserable and we all get sore throats for a few days.

      The GOES 6km visible satellite images have been showing them for the last week or two, Mark. Your link was from yesterday. This evening (Sunday) you may just be able to catch the last of the visible frames for the day. Its aerosols if you can see them – so probably smoke. They're not on the IR images.

      They seem to be near salt domes or oil fields a lot of time, but that's also where the cane fields are in the Gulf.

    Before you make up a response based on theory RE: is the Canadian quake connected to the southern LA area, I'd suggest you look at the DATA. Go here: http://folkworm.ceri.memphis.edu/heli_bb_nsn/
    Everything along the North American craton was affected, whether you agree with "subduction zones" or NOT, doesn't alter the seismic data, including Texas, Pennsylvania, Missouri, Tennessee, even Disney World, for crying out loud. And as far as letting this so called expert geologist off the hook because the BRAND NEW wells were plugged… I seriously doubt that's what happened. Remember…this geologist is the "expert" whose AUDIENCE HE CAME TO INFORM had to tell him the sequence of events. If you were investigating a potentially catastrophic event as an expert geologist, wouldn't the first thing you asked be: What was the sequence of events? Yet he did NOT KNOW THE GAS HAD BEEN BUBBLING FOR MONTHS, but instead conjectured the earthquakes came first and released the gas. THIS IS NOT AN INSIGNIFICANT DIFFERENCE and would seem to indicate PRESSURE FROM THE GAS CAUSED the earthquakes and NOT THE OTHER WAY AROUND. And Kalidances, you are absolutely right to be outraged at the ho hum attitude for the safety of those involved. We ALREADY KNOW they're ALREADY DYING from fumes. But some here are more concerned with "but where would we house them? and for how long?" We should be organizing CHURCH GROUPS to cross match families with appropriate host families. Contact Debra Dupre…

      I'm not disagreeing with you about the connection. I disagree with the theory of continental subduction. Read what i post before going off half loaded, please. If you recall, the geologist you are dissing was given a summary brief which he went by before the townhall meeting. Has he made mistakes? Of course. But, he's being frank and honest.

    @irhologram, i watched the vid you just linked and Dutchsinse says that "I think they are coming from the ground. Just my opinion guys, but take it for…" Was there maybe a different source that actually has gone up to one of these sites and taken a look to see if field burning or volcanic venting is going on? The difference could be important, to say the least. Or, did i miss the video you meant? We get a little steam venting from Mt. St. Helens here and occasionally one of the other mountains along the Cascades here will put out some steam, but nothing much since St. Helen's blew. I think Mt. Rainier just had a little activity, but, most of this mountain range is still considered volcanically active.
