Hurricane Harvey is the most powerful storm to hit Texas in over half a century, wreaking havoc across the state and causing at least two fatalities. High winds and widespread flooding have devastated the Gulf Coast, and the U.S. petroleum industry is feeling the impact as a result. Many refineries have ceased production, while several ports involved in the export of oil have closed. Reuters reports that between Texas and Louisiana, refining capacity is capped at roughly 8.9 million bpd, with Texas contributing 5.6 million bpd and Louisiana contributing 3.3 million bpd. With the arrival of Hurricane Harvey, an estimated 2 million bpd has been knocked out.
