HUGE Methane Bubble Site Found Within 100 ft Of Bayou Corne Home…

This newest methane bubbling site is in the northwestern most edge of the Bayou Corne community.

This is the first BIG bubble site in the bayou that I am aware of on the north side of HWY 70, and so far west. [...]

    Latest OnWingsOfCare flyover is showing indications that larger problems are probably manifesting themselves (patches of brown trees scattered and the bayou itself appears unusually tan colored) http://youtu.be/LkOqwgo42-8

    What's interesting to me is the bubble sites that are leaking thru terra firma but can't be seen. Chances are there are as many release points thru soil as can be observed in the water.

    Some still morning when the escaping methane gas has concentrated low to the water/ground, I fear there will be a large explosion like what happened in Brenham, Texas. http://www.youtube.com/watch?v=IpYIvyCXv9w

      That was a pipeline rupture, not seepage. There is no comparison in the volume of gas released. Seepage releases gas far too slowly for there to be a methane/oxygen mix required for an explosion of that nature. At most, on a day where the winds were stilled, you'd have a fire smaller than the flare off vents. On a windy day, above 5 mph, a small campfire size flame is about max.

      Hey Cisco. One of my latest understanding about the methane dynamic of this is that there will be several concentric rings of leak sites where the "settlement" zone is. Before this collapse happened the land was relatively flat. Sand and Gravel that support the clay confining layer are falling in and reducing the thickness of the Miss. River Alluvial Aquifer in a rough circle around the throat of the collapse zone. This effectively forms a cone centered around the collapse zone which has concentric lines of gas pathways where the soil deformed over time, leaving concentric circles of gas leaking through these pathways of least resistance. The concentration of bubbling sites would be on or near the outside perimeter of the "settlement" zone due to the subterranean slope of the confining layer. The gas that can't go through to the sinkhole will reroute up the sides of this clay funnel. Judging from the past bubbling maps it appears that the majority of the gas travels North and West of the collapse zone.

      I agree there are certainly many bubbling sites that are not identified just because they are on "dry" land. If someone wanted to identify them all they have to do is focus on the perimeter of the "collapse" zone and work out from there. When I used to check pipes for gas leaks we used soapy water because it formed very visible bubbling where there was a leak. I am not implying that soap be used in B.C. but something which bubbles would work.

    For those of you who have it, Googleearth has 'updated' its imagery of the area.

    The sinkhole ( Lake Fubar ) & berm are now included.
