Hugh Pickens writes writes "Simone Sebastian writes in the Houston Chronicle that the nation's energy transportation network is undergoing a multibillion-dollar overhaul, as oil and natural gas production surges in new regions of the country and energy producers charge into new areas with technology that can reach oil and natural gas trapped in shale and other tight rock formations leaving pools of crude and gas stranded far from the Gulf Coast refineries and petrochemical plants that need them. "Where it used to be isn't where it is now. Where it needs to go isn't where it used to go," says Terrance McGill, president of fuel carrier Enbridge Energy. "You're seeing this fundamental shift of crude oil across the country." For example Phillips 66 CEO Greg Garland says his company is considering buying 2,000 more rail cars that could carry an additional 150,000 barrels a day from shale regions (PDF) to its refineries across the country because the glut of crude oil pouring out of the newly tapped shale oil plays like North Dakota’s Bakken has kept the price of Mid-Continent crude at a record-wide discount of up to $27 per barrel relative to its rival European benchmark Brent crude because there is not enough pipeline capacity to get Bakken crude to Gulf coast refineries. "That's a pipeline on wheels," says Garland. "You'll see us stepping out and doing some more things around infrastructure. Like everyone else, we're doing everything we can to get more barrels in front of those facilities.""
