Texas Brine LLC fingered as culprit of gas seepage near sinkhole
A press release issued Thursday by the Louisiana Department of Natural Resources says based on samples taken from the sinkhole, Bayou Corne, and near the failed Napoleonville Salt Dome indicate Texas Brine's failed cavern is the likely source of the natural gas and crude oil that has been seeping into the area's water supply.
"We have been driven by scientific data in all of our efforts to determine the cause of the natural gas found in the aquifer, the formation of the sinkhole, and the presence of crud oil found on the surface of the sinkhole," says Commissioner of Conservation James Welsh in a prepared statement.
“Establishing how natural gas reached the aquifer and what caused the formation of the sinkhole was an important step in the process, but the work is not yet done. We will continue to hold Texas Brine accountable and ensure that this work is completed as quickly as possible, in a manner that protects their safety and the environment."
According to DNR's press release:
Welsh noted that, based on “fingerprint” analysis and other data, the source of the crude oil and natural gas that have been observed at the surface in the Bayou Corne area appears to be one or more naturally occurring oil and natural gas formations, and that the preponderance of scientific evidence indicates that the failure of the sidewall of the Texas Brine cavern provided a pathway up to the aquifer and the surface for oil and natural gas that had previously been confined thousands of feet below.
Texas Brine, according to Welsh's orders, must:
• Maintain stability of pressure in the failed cavern to prevent additional changes to the cavern or sinkhole due to pressure changes. • Install monitoring wells in the Bayou Corne community to monitor water quality and pressures, as well as elevation benchmarks within the community for subsidence monitoring. • Install pressure monitor at wellhead of the cavern re-entry well, designed to provide real-time data to parish emergency response agencies of any rapid pressure change. • Upgrade and expand seismic monitoring array to cover a wider area and include real-time data processing and interpretation of micro-seismic data, with seismic data reported in real-time to parish emergency response agencies. • Install continuous water level monitoring station at the sinkhole. • Collect and interpret geophysical data to determine the exact structure of the zone of failure and its impact on the surface and subsurface.
An effort also is under way, according to DNR, to increase the number of "observation/vent wells" in the area to aid in the removal of the natural gas that has seeped into the aquifer near Bayou Corne.

DEC 18 Here's a story in Newsweek about the Bayou Corne sinkhole (warning: autoplay video here). It is a long, detailed, very comprehensive story. It's definitely more comprehensive than the local media coverage to date. There's a lot of information about the sinkhole (new information, really) but there's also a look at the phenomenon of "Cancer Alley."
DEC 18 A recent poll of possible gubernatorial candidates has Sen. David Vitter in the lead, Jeremy Alford writes on LaPolitics. He's polling at 25 percent, followed by Mitch Landrieu at 20 percent and Jay Dardenne at 12 percent. Here's what Jeremy didn't address: did Vitter interrupt his prayerful consideration to look at these results? The world may never know. Here's something else, that we will know, eventually: how soon before the first commercial mentioning the unmentionable airs?
DEC 18 Blogger Robert Mann has some advice for Governor Jindal: take your own. Mann pulls out some 2008 quotes from the governor on health care for the poor and contrasts them against the governor's more recent actions (or inaction) in the same arena. Part of the plan? Expand Medicaid. Wait -- what??
DEC 18 Here's a sweet post on Gambit by Ken Bode about the passing of George Rodrigue. Bode met the artist 30 years ago, and has a lot of funny stories about his friend. One of the best is how much George laughed over learning that President Clinton re-gifted a set of Blue Dog earrings -- to Ken Starr. The portrait Bode paints here is one of a man who loved life, and was constantly reminding the rest of us that we should, too.
DEC 18 Conservative blogger Rod Dreher doesn't usually agree with The Advocate (the national publication, which is the largest gay magazine in the country) but in this post he does. The Advocate, like Time, has named Pope Francis its person of the year. Punctuating that are some recent moves the Pontiff has made, including the removal of a vocally anti-gay Bishop from a position of power. As usual, Dreher gives us a lot of information and raises questions, encouraging readers to think it over. But he does agree with the Advocate's selection, calling it "a savvy choice."
DEC 18 Ever since a recall election put an end to the ongoing Deedy vs. Hootie saga over in Port Allen, the City Council has been working hard to prove all the problems didn't rest with former mayor, Deedy Slaughter, by failing to appoint her temporary replacement. Gov. Jindal was stuck with the job, so he picked a former mayor to take over the reins. Let's hope that lady is eating her Wheaties; she's gonna need the energy.
DEC 18 Blogger Tom Aswell seems to hear all the good rumors, and this one is a really good one: there's a plan to get Sen. David Vitter elected governor and then appoint Gov. Bobby Jindal to serve out the last year of Vitter's Senate term. Hey, that's a great idea, and if there's anything Bobby has made clear, it's that he would prefer to live in DC anyway.
