BSEE Reports Hurricane Michael Activity Statistics: Oct. 10, 2018
https://www.bsee.gov/newsroom/latest-news/statements-and-releases/press-releases/bsee-reports-hurricane-michael-1...Based on data from offshore operator reports submitted as of 11:00 a.m. CDT today, personnel have been evacuated from a total of 89 production platforms, 13.0 percent of the 687 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 three rigs (non-dynamically positioned), equivalent to 13.6 percent of the 22 non-DP 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 four dynamically positioned rigs have moved off location out of the storm’s path as a precaution. This number represents 23.5 percent of the 17 rigs of this type currently operating in the Gulf. Dynamically positioned rigs maintain their location while conducting well operations by using thrusters and propellers, the 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. 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 42.3 percent of the current oil production in the Gulf of Mexico has been shut-in. It is also estimated that approximately 31.7 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....
