Hurricane Harvey hit Houston hard. Harder than many expected, including a number of the oil and gas companies located in the area. Some evacuated early and had no idea when they would reopen for business.
“How soon they reopen depends on the severity of flooding and the resumption of power to the areas. Experts say it's still too early to say, with the storm still moving through the region. But they believe gas prices will increase 5 cents, to 25 cents per gallon.” (CNBC.com)
