NEW ORLEANS—An out-of-control natural gas well off the Louisiana coast continues to burn after it caught fire following a blowout that prompted the evacuation of 44 workers, authorities said.
Meanwhile, officials stressed that the blowout wouldn’t be close to as damaging as the 2010 BP oil spill, in which an oil rig, the Deepwater Horizon, exploded off the Louisiana coast, killing 11 workers and eventually spewing millions of gallons of oil into the Gulf of Mexico.
No injuries were reported as a result of the fire, Eileen Angelico, a spokeswoman for the Bureau of Safety and Environmental Enforcement (BSEE), told The Associated Press.
She said it wasn’t known what caused the gas to ignite.
It also wasn’t clear how and when crews would attempt to extinguish the blaze.
BSEE said a firefighting vessel with water and foam capabilities had been dispatched to the scene.
Wild Well Control Inc. was hired to try to bring the well under control.
Angelico said Wild Well personnel approached the well the night the blowout, before the fire, but they determined it was unsafe to get closer when they were about 200 feet away from it.
The gas blowout was reported early July 23.
The Coast Guard kept nautical traffic out of an area within 500 metres of the site throughout the day.
The Federal Aviation Administration restricted aircraft up to 2,000 feet above the area.
BSEE said inspectors flying over the site soon after the blowout saw a light sheen covering an area about a half-mile by 50 feet.
However, it was dissipating quickly.
Earlier this month, a gas well off the Louisiana coast flowed for several days before being sealed.
The recent blowout occurred near an unmanned offshore gas platform that was not currently producing natural gas, said Angelico.
The workers were aboard a portable drilling rig known as a jackup rig, owned by Hercules Offshore Inc., which was a contractor for exploration and production company Walter Oil & Gas Corp.
Walter Oil & Gas reported to the BSEE that the rig was completing a “sidetrack well”—a means of re-entering the original well bore, Angelico said.
The purpose of the sidetrack well in this instance was not immediately clear.
A spokesman for the corporation did not have the information as of press time.
Industry websites say sidetrack wells are sometimes drilled to remedy a problem with the existing well bore.
“It’s a way to overcome an engineering problem with the original well,” Ken Medlock, an energy expert at Rice University’s Baker Institute, said. “They’re not drilled all the time, but it’s not new.”
