Officials say 11 new bubble sites have been found in inundated swampland west of an 8.5-acre sinkhole in northern Assumption Parish.
The sites are roughly in a row west of an unnamed oilfield access road extending south from La. 70 South through the wooded swamp.
The Advocate reports the sites bring to 34 the number of known bubble sites in the Bayou Corne and Grand Bayou areas in the vicinity of the sinkhole on Texas Brine Co. LLC’s leased property.
Scientists think the Houston-based company’s salt cavern in the Napoleonville Dome failed deep underground, causing the sinkhole and unleashing oil and natural gas from formations along the salt dome face. That free gas is thought to be surfacing through many bubble sites and the sinkhole.
