PORT FOURCHON, LA (NBC33) — Crews are working at a platform in the Gulf of Mexico today to create a temporary plug for a well that began leaking yesterday. 
According to the Coast Guard and Bureau of Safety and Environmental Enforcement, the leak started Tuesday, July 9 on a natural gas and crude oil platform located approximately 74 miles southwest of Port Fourchon. A temporary plug sealed Well #B2, but not before a 4 mile wide by 3 mile long oil sheen was spotted on the surface of the water.
A plan is being set in motion to create a permanent seal for the well. We’re told drilling mud will likely be pumped in to stop the small flow. They say the sheen is expected to evaporate.
The Coast Guard and BSEE will conduct an investigation to determine what caused the leak.
The platform is owned by Energy Resources Technology Gulf of Mexico, LLC.
