Here's the latest. Breakdown delays drill in sinkhole probe The Advocate. Excerpts:
..
The sinkhole was found Aug. 3 in Texas Brine swampland property between the Bayou Corne and Grand Bayou communities south of La. 70 South, prompting the evacuation of residents from about 150 homes in the vicinity. The sinkhole appeared after two months of natural gas releases in area waterways and earth tremors, both of which have continued.
The sinkhole, which has grown larger as dirt and trees on its rim have sloughed off and fallen into the water since it emerged, including this week, is now about 475 feet across and an estimated 4 acres in size, according to new parish dimensions.
The Louisiana Department of Natural Resources ordered the well be drilled after scientists suspected a nearby company salt cavern in the Napoleonville Dome failed, released its brine contents and caused the sinkhole.
John Boudreaux, director of the parish Office of Homeland Security and Emergency Preparedness, said Friday’s mechanical failure involved a mud pump near the bit at the tip of the drill pipe.
He said the failure forced the entire drill pipe to be removed Friday so the bit and pump could be replaced and reinserted in the drill hole, which has reached 3,180 feet in depth. The bit had reached a point about 300 feet above the cavern roof, Texas Brine officials said.
The videographer recorded two men at the site of the sinkhole. That's it? Two guys? Shouldn't the EPA be studying the fuck out of this thing? Also: There's still no coherent crisis response from any of the parties involved. Anything else you can tell us, other than "Mud pump broke!,"? Anything? Anyone?
