Gas Continues to Escape from Rig off Louisiana Coast

The Bureau of Safety and Environmental Enforcement (BSEE) and the Coast Guard continue to oversee EnVen's efforts to stop the flow of natural gas from the A-7 well at Vermilion Block 356 in the Gulf of Mexico, approximately 108 miles southwest of Lafayette, Louisiana.

The operator, EnVen, reported Thursday that it was drilling from the jack-up rig, Rowan Louisiana, when the well began to flow natural gas. The flow was diverted overboard and work began to stop the flow. No visible sheen has been reported.

BSEE is in the final stages of reviewing EnVen's plans and procedures to use a dynamic kill process to stop the flow of natural gas. Once approved, it is anticipated that EnVen will begin the process late this afternoon. A dynamic kill involves pumping weighted drilling fluids (usually termed mud) into the well to apply pressure and stop the flow of hydrocarbons from the reservoir.

All production from the A-Platform, which is located under the jack-up rig, remains shut-in. As a precaution, personnel onboard the platform were evacuated. No injuries have been reported.

BSEE is leading a coordinated response with the Coast Guard and will continue to provide updates as they become available. BSEE will investigate the incident.
