BSEE Tropical Storm Isaac Activity Statistics Final Update: September 11, 2012

09/11/2012

NEW ORLEANS — The Bureau of Safety and Environmental Enforcement (BSEE) Hurricane Response Team is concluding its activities related to Tropical Storm Isaac. This is the final update of evacuation and shut-in production statistics for Tropical Storm Isaac. 

Based on data from offshore operator reports submitted as of 11:30 a.m. CDT today, personnel remain evacuated on a total of two production platforms, equivalent to .3 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 remain evacuated from one rig, equivalent to 1.32 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 4.16 percent of the current daily oil production in the Gulf of Mexico has been shut-in. It is also estimated that approximately 4.73 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. The remaining shut-in oil and gas production has been slow to return due to damage at onshore processing facilities.

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 no longer report Tropical Storm Isaac statistics.

  Total Percentage of GOM
Platforms Evacuated 2 .03%
Rigs Evacuated 1 1.32%
  Total shut-in Percentage of GOM Production

This survey information is reflective of 19 companies’ reports as of 11:30 a.m. CDT today.
