BSEE Tropical Storm Isaac Activity Statistics: September 3, 2012

NEW ORLEANS —  Offshore oil and gas operators in the Gulf of Mexico are re-boarding platforms and rigs, and restoring production following Tropical Storm Isaac. The Bureau of Safety and Environmental Enforcement (BSEE) Hurricane Response Team is activated and monitoring the operators’ activities. The team will continue to work with offshore operators and other state and federal agencies until operations return to normal.

BSEE inspectors are flying offshore and inspecting production platforms and drilling rigs. BSEE Hurricane Response Team is receiving some damage reports from oil and gas operators and is verifying and compiling the information. Initial reports indicate mainly minor damage at this point.

Based on data from offshore operator reports submitted as of 11:30 a.m. CDT today, personnel have been evacuated from a total of 71 production platforms, equivalent to 11.91 percent of the 596 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 19 rigs, equivalent to 7.89 percent of the 76 rigs currently operating in the Gulf. Rigs can include several types of self-contained offshore drilling facilities including jackup rigs, submersibles and semisubmersibles.

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. During previous hurricane seasons, the shut-in valves functioned 100 percent of the time, efficiently shutting in production from wells on the Outer Continental Shelf 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, it is estimated that approximately 58.29 percent of the current daily oil production in the Gulf of Mexico has been shut-in. It is also estimated that approximately 38.62 percent of the current daily 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.

Offshore oil and gas facilities are currently being inspected. Once all standard checks have been completed, production from undamaged facilities will be brought back on line immediately. Facilities sustaining damage may take longer to bring back on line. BSEE will continue to update the evacuation and shut-in statistics at 1:00 p.m. CDT each day as appropriate.

This survey information is reflective of 52 companies’ reports as of 11:30 a.m. CDT today.
