BSEE Bureau of Safety and Environmental Enforcem : Monitors Gulf of Mexico Oil and Gas Activities in Response to Hurricane Zeta

NEW ORLEANS - Bureau of Safety and Environmental Enforcement (BSEE) has activated the Hurricane Response Team as Hurricane Zeta made its way through the Gulf of Mexico. The Hurricane Response Team is monitoring offshore oil and gas operators as they evacuate platforms and rigs in the Gulf of Mexico in response to Hurricane Zeta. The team works with offshore operators and other state and federal agencies until operations return to normal and the storm is no longer a threat to Gulf of Mexico oil and gas activities.

Based on data from offshore operator reports submitted as of 11:30 CDT today, personnel have been evacuated from a total of 94 production platforms, 14.62 percent of the 643 manned platforms in the Gulf of Mexico. Production platforms are the structures located offshore from which oil and natural gas are produced. Unlike drilling rigs, which typically move from location to location, production facilities remain in the same location throughout a project's duration.

Personnel have been evacuated from one rig (non-dynamically positioned), equivalent to 10 percent of the 10 rigs of this type currently operating in the Gulf. Rigs can include several types of offshore drilling facilities including jackup rigs, platform rigs, all submersibles and moored semisubmersibles.

A total of one dynamically positioned rig has moved off location out of the hurricane's projected path as a precaution. This number represents 6.25 percent of the 16 dynamically positioned rigs currently operating in the Gulf. Dynamically positioned rigs maintain their location while conducting well operations by using thrusters and propellers. These rigs are not moored to the seafloor; therefore, they can move off location in a relatively short time frame. Personnel remain on-board and return to the location once the storm has passed.

As part of the evacuation process, personnel activate the applicable shut-in procedure, which can frequently be accomplished from a remote location. This involves closing the sub-surface safety valves located below the surface of the ocean floor to prevent the release of oil or gas, effectively shutting in production from wells in the Gulf and protecting the marine and coastal environments. Shutting-in oil and gas production is a standard procedure conducted by industry for safety and environmental reasons.

From operator reports, BSEE estimates that approximately 59.18 percent of the current oil production in the Gulf of Mexico has been shut-in. BSEE estimates that approximately 31.98 percent of the natural gas production in the Gulf of Mexico has been shut-in. The production percentages are calculated using information submitted by offshore operators in daily reports. Shut-in production information included in these reports is based on the amount of oil and gas the operator expected to produce that day. The shut-in production figures therefore are estimates, which BSEE compares to historical production reports to ensure the estimates follow a logical pattern.

After the storm has passed, facilities will be inspected. Once all standard checks have been completed, production from undamaged facilities will be brought back online immediately. Facilities sustaining damage may take longer to bring back online.

	Total	Percentage of GOM
Platforms Evacuated	94	14.62
Rigs Evacuated	1	10
DP Rigs Moved-off	1	6.25
	Total shut-in	Percentage of GOM Production
Oil, BOPD Shut-in	1,094,913	59.18
Gas, MMCFD Shut-in	866.58	31.98

BSEE will continue to update the evacuation and shut-in statistics at 1:00 p.m. CDT each day as appropriate. This survey is reflective of 36 companies' reports as of 11:30 CDT today.
