Global trader Trafigura AG is seeking potential investors to buy a stake in its oil terminal and storage facility in Corpus Christi, Texas, a once-quiet port that has become a bustling hub for shipping Eagle Ford shale crude. Trafigura, which like other big commodity merchants has in recent years moved to buy key infrastructure assets to support its trading business, bought Texas Dock & Rail in early 2012, just as Eagle Ford production was emerging as the next big U.S. shale play after North Dakota's Bakken. It has since built the facility, once home to a failed steel plant, into a major gateway for shipping rapidly growing U.S. oil production as far as Canada, with two deepwater tanker berths and an expanding suite of logistical assets.
