Large Sinkhole Forms – Drilling Issues Suspect

Bayou Corne South Louisiana
Sink hole develops near Bayou Corne in gas and oil field

NEAR BAYOU CORNE, LOUISIANA — A large sink hole formed Thursday night and Friday morning in the swamps below La. 70 South in a part of northern Assumption Parish where unexplained gas bubbles have been rising from nearby bayous and tremors have been felt for more than two months, a parish official said Friday. A diesel smell was present at the time but has dissipated according to a parish official.

John Boudreaux, director of the parish Office of Homeland Security and Emergency Preparedness, estimated the sinkhole is about 200 feet by 200 feet. It is on private land near the Texas Brine Co. LLC facility but it is unknown at this point on whose land the hole is actually located.

Texas Brine has yet to make a statement concerning the sink hole.

Natural gas has been seeping up from Bayou Corne and Grand Bayou, which run below and along the side of the area of the reported sink hole. A suspected water well in the same area has also been venting natural gas.

Residents have also reported contemporaneous tremors in the area, which has a known fault and a salt dome that is mined for brine and used for hydrocarbon storage.

Federal, state and parish official have been unable so far to pin down the cause of the earthquakes or the source of the natural gas releases, despite of battery of tests on the oil, gas and brine production infrastructure in the area.

It is not clear at this point whether the smell and sinkhole are related to the natural gas bubbles, the earth tremors or each other.
