Personnel monitoring the Bayou Corne sinkhole in Assumption Parish detected a small disturbance, or burp, Saturday afternoon that released debris and hydrocarbons in the center of the 22-acre sinkhole.
After researcher Stephen Horton noticed increased activity in the sinkhole about 1:30 p.m., he alerted officials the incident had taken place, said John Boudreaux, director of the Assumption Parish Homeland Security and Office of Emergency Preparedness.
Boudreaux said there are several air-monitoring sites in the vicinity and the readings after the afternoon event indicated that hydrocarbons in the atmosphere were well below harmful levels.
Boudreaux said burps occur when hydrocarbons located deep in the earth work their way upward and escape through the sinkhole into the atmosphere.

Powerful earthquakes thousands of miles (km) away can trigger swarms of minor quakes near wastewater-injection wells like those used in oil and gas recovery, scientists reported on Thursday, sometimes followed months later by quakes big enough to destroy buildings.
The discovery, published in the journal Science by one of the world's leading seismology labs, threatens to make hydraulic fracturing, or "fracking," which involves injecting fluid deep underground, even more controversial.
LOS ANGELES (AP) — The powerful earthquake that rocked Japan in 2011 set off tremors around a West Texas oil field, according to new research that suggests oil and gas drilling operations may make fault zones sensitive to shock waves from distant big quakes.
It's long been known that large quakes can trigger minor jolts thousands of miles from the epicenter. Volcanically active spots like Yellowstone National Park often experience shaking after a large distant event.
Less is known about the influence of remote quakes on fault lines that have been weakened by man-made activity like the deep disposal of wastewater at the Texas oil field. A new study led by researchers at Columbia University and published Friday in the journal Science suggests a strong quake that strikes halfway around the globe can set off small to mid-size quakes near injection wells in the U.S. heartland.
An analysis of earthquakes in the area around the Salton Sea Geothermal Field in southern California has found a strong correlation between seismic activity and operations for production of geothermal power, which involve pumping water into and out of an underground reservoir.
What confidentiality would be breached by the disclosure of this I wonder? Maybe it shows the collapse of different areas not just the area around Oxy#3 and THAT would be a concern for far more people and open them up to a MUCH bigger compensation claim. You wait, they will file for bankrupcy or do some serious company name shifting. What are the directors doing with their shares? Follow the money and the money will tell the whole story.
it sounds like the Louisianna DNR has serious issues with Texas Brine's interpretation of the 3D seismic data.
They are reprocessing & doing their own interpretation from the raw data, which TB did not want to share because of "confidentiality" concerns.

but the USGS depth is measued in tenths of a kilometre which is either unscientific or else they are able to accurately measure depths by triangulation in 3d space. I cannot imagine scientists using guestimates in this depth measurements so they probably only publish tenths of a Km when in actual fact they can probably resolve it to a few hundredths with a larger margin for error.
Most earthquakes listed on USGS have location error estimates listed in kilometers, so maybe more precision isn't possible?
Yes, I can imagine this is what would cause it. Large bubbles rising to the surface of a liquid. That in itself is very disturbing since this is probably methane and it means that the hole to the methane store is large - creating large bubbles rather than a stream of smaller ones.
I wonder what causes it to oscillate like that? Water/hydrocarbons from below bubbling up and displacing the surface water which then rushes back into the void?
