The explosion and fire at a natural gas rig off the Louisiana coast raise new questions about the role of blowout preventers and overall safety of drilling operations in the Gulf.

The natural gas rig that was burning and leaking off the Louisiana coast is under control, according to federal regulators.
Natural gas has stopped leaking from the well and the fire has decreased to a small flame fueled by residual gas at the top of the well, the Bureau of Safety and Environmental Enforcement (BSEE) and the Coast Guard announced Thursday. The agencies said the leak stopped due to bridging, a well condition where small pieces of sediment and sand flow into the well path and restrict and ultimately stop the flow.
Investigators are still determining what caused the natural gas blowout and subsequent fire, and don’t expect to have immediate answers. But the accident is already raising questions about the role that blowout preventers played – and whether safety standards in the Gulf Coast have improved since the 2010 Deepwater Horizon disaster.
