Well more than half of the oil production in the Gulf of Mexico is now offline because of safety concerns regarding Tropical Storm Barry.
That means more than 1 million barrels of oil per day is out of commission for at least a few days - a volume that could still rise - as Barry aims for a Saturday landfall in Louisiana as either a tropical storm or hurricane, according to the federal Bureau of Safety and Environmental Enforcement.
Nearly 200 production platforms in the Gulf were evacuated this week - close to 30 percent of all manned platforms. More than 53 percent of oil output and about 45 percent of all natural gas production in the Gulf are offline as well, the federal government estimated.

The Gulf's leading producers - BP, Royal Dutch Shell and Chevron - said they evacuated much of their offshore personnel and shutting down oil and gas output at many of their sites in preparation of the strengthening storm.
Other large Gulf producers like The Woodlands-based Anadarko Petroleum and Australia's BHP evacuated multiple platforms as well.
