“The situation is degrading.” Wilma Subra who lives near the sinkhole area has been working night and day.
They are finding shallow pockets of gas, seismic activity is increasing and new bubbling areas are appearing.
There are fifty-one oil and gas-related caverns in the 1-mile by 2-mile salt dome storage facility, the source of the declared state of emergency.
Two monitoring wells hit natural gas pockets at less than 50 feet between “the western edge of the Napoleonville Salt Dome and the Bayou Corne community.” Texas Brine, the operator of the salt dome nearest the sinkhole hit a shallow pocket of gas at 120′ and another at 420′ while drilling a well to assess conditions in the salt dome.
“The data indicated pockets of natural gas within the Mississippi River Alluvial Aquifer and the cap rock above the salt dome,” DNR stated. “That data came after DNR ordered Texas Brine to evaluate below ground conditions.
Some of the new bubbling sites are near a salt cavern where Crosstex stores 1.5 million barrels of highly volatile liquid butane.
