Harvey's impacts on the energy sector

Harvey's devastating flooding is hitting a state and region that's a central hub for the energy sector. For instance, BP and Shell alone have roughly 11,000 employees in the Houston region combined.

The storm is closing down refineries, some crude oil production offshore in the Gulf of Mexico and onshore in the Eagle Ford shale region, pipelines, shipping, and other infrastructure networks.

Via a sobering Reuters story: "Damage assessments could take days to weeks to complete, and the storm continues to drop unprecedented levels of rain as it lingers west of Houston, home to oil, gas, pipeline and chemical plants. And restarts are dangerous periods, as fires and explosions can occur."
