Twin Eagle Sand Logistics LLC placed its first 130-car frack sand unit train at Mission Rail in Elmendorf, Texas. The city is in the core of the Eagle Ford Shale, parent company Twin Eagle Resource Management said.

Mission Rail is a 1,000-acre Union Pacific industrial rail terminal near San Antonio, on the edges of the Eagle Ford.

The extralong unit train is one of the largest frack sand trains used in the Eagle Ford, Twin Eagle Resource said. It was offloaded into Twin Eagle Sand’s new, 60-million-pound frack sand silo system. The system can hold up to 300 rail cars’ worth of frack sand, and can load a truck in under two minutes.

Twin Eagle Sand has terminals across major U.S. basins. A terminal is under development near Big Springs, Texas. Combined, the current terminals control more than 900 rail car spaces with about 50,000 tonnes of storage capacity.

"Longer laterals, more stages and closer spacing of wells are increasingly common in today's shale plays, which is why frack sand intensity per well continues its rise," Griff Jones, Twin Eagle Sand's CEO. "We believe that world-class terminal infrastructure like what we have developed at Mission Rail is necessary to reduce logistics costs of completing wells and improving our customers' breakeven costs of completion."

Houston-based Twin Eagle Resource Management LLC is a midstream service provider.
