Bayou Corne sinkhole

New sinkhole image shows ‘original edge’ of Napoleonville salt dome may be gone — Section thousands of feet tall

This is going to be really nasty.

Chris Piehler, Louisiana Department of Environmental Quality:

In fact, we got a call from down in [???] St. Vincent, “I’ve got gas in my well too.” …

Went down there and sampled his well…

I told Mr. Pate at the time that some of the samples I collected there looked very, very similar to the same samples I was collecting form those industrial wells…

That would be very remarkable [if samples are similar]…

All of a sudden that expands the reach of this thing another 4 miles from what the site is.

It's gonna get very big.

A formation whose oil and gas material might migrate to the surface and reek havoc is named Big Hum. Only in Louisiana.

I don't understand the complexity of such a geologic event. Do you know anything about this that's not exactly explained by the news?

Gary Hecox, a geologist with Shaw Environmental said: “The other likely source we’re looking at is gas and crude coming in from the gas and crude production horizons that are around the dome. Right now at the elevation of the cavern, the top to the bottom of the cavern, according to the 3-D seismic that’s been done out here, there are three historical production zones that are at the same elevation of the cavern — The Big Hum, the Cris R and the Mary V

I would surmise that part of the cavern has collapsed and is allowing the surrounding to shift and collapse into it.

Texas Brine had abandoned the cavern because it lost pressure integrity. That, to me, means a leak. That could give a path back to the cavern, as well as out, and erosion a go.

I would think the path is through the side of the salt, into the surrounding formations, deep down in the ground.

I figured last summer when the failed pressure test was mentioned, the whole sinkhole situation might well be tied to it.

They are eluding to the erosion of the salt layer?

I'm watching this:

[Pigeon]

They are eluding to the erosion of the salt layer?

Yes. A huge side of the cavern may have failed, 3000+ ft down.

They are eluding to the erosion of the salt layer?

Yes. A huge side of the cavern may have failed, 3000+ ft down.

The geologist in the video says it's completely gone. From the explanation given, the sinkhole will not stop until the cavern is filled.
