The US Energy Information Administration said in an October 9 assessment that Hurricane Isaias’s approach to the Gulf Coast had affected oil and natural gas production. Citing the Bureau of Safety and Environmental Enforcement, EIA reported that 130 production platforms and rigs had been evacuated or moved as of October 8.

The resulting shut-ins represented about 1.3 million barrels of crude oil and 1.1 billion cubic feet of natural gas per day. EIA noted that the Gulf Coast contains a large share of US refining capacity and said the storm could also affect refinery operations; the release did not quantify refinery outages already realized.
