From the EIA’s Today in Energy:
”Monthly U.S. crude oil production fell by 276,000 barrels per day (b/d) in July 2019, based on the latest data in the U.S. Energy Information Administration’s (EIA) Petroleum Supply Monthly. This hurricane-related decrease was the largest decline in monthly crude oil production in more than a decade. The decline was temporary and geographically isolated to the Federal Offshore Gulf of Mexico. EIA expects that U.S. crude oil production will continue to increase through the remainder of 2019.
Crude oil production in the Federal Offshore Gulf of Mexico fell by 332,000 b/d in July when some production platforms were evacuated in anticipation of Hurricane Barry. According to information from the U.S. Department of the Interior’s Bureau of Safety and Environmental Enforcement (BSEE), 283 offshore oil and gas platforms in the Gulf of Mexico (about 42% of the regional total) were evacuated in mid-July as Barry approached.
BSEE estimated that about 70% of Gulf of Mexico crude oil production was shut in (i.e., not operating) at the peak of the disruption as a result of the evacuation. Excluding the Federal Offshore Gulf of Mexico, U.S. crude oil production in the rest of the United States rose by a combined 56,000 b/d in July, partially mitigating the disruption.
Historically, many of the largest monthly declines in U.S. crude oil production were the result of hurricanes. Hurricanes Gustav and Ike led to crude oil production falling by more than 1 million barrels per day in September 2008. Hurricanes Katrina and Rita led to a similar month-on-month decline in September 2005.”
