Shale Seen Shifting Flows at America’s Biggest Oil Port

For more than 30 years, the Louisiana Offshore Oil Port LLC has been a symbol of U.S. dependence on foreign oil, pumping Nigerian and Saudi Arabian crude from the world’s biggest supertankers into underground storage caverns beneath the marshes of southern Louisiana.

Now, with domestic production at a 28-year high, LOOP’s managers are thinking the previously unthinkable: They want to reverse the flows and send North American oil out as well as take foreign oil in.
