A Canadian company says it ran frac pumps on liquefied natural gas to complete a well in Texas' Eagle Ford Shale, which it said marked the first time that's been done. Frac pumps are typically driven by big diesel engines, and Ferus L.P., based in Calgary, said it used a dual-fuel approach using LNG and diesel simultaneously. Ferus said it was a pilot project for an unnamed producer and used 10,000 gallons of LNG, which has fewer emissions than diesel. The report comes the same day Exxon Mobil, in its 2013 energy outlook, said LNG for over-the-road trucks would be an expensive conversion process, but could prove economic long-term.
