Concentrations of methane, ethane and propane were found in higher levels in drinking water for homes within a kilometer of shale gas wells in parts of the Marcellus Shale in northeast Pennsylvania, according to a study released Monday. It was the third such study by Duke University’s Robert Jackson, a professor of environmental sciences.

Encana Corp. and liquefied natural gas (LNG) fueling solutions provider Ferus LNG Inc. plan to build a 190,000 liter per day LNG production facility near Grande Prairie, Alberta (AB). The facility is to be near high levels of energy industry activity in northwestern Alberta and northeastern British Columbia and is expected to be operational by the end of 2013. It would be among the first in Canada designed to produce high-quality LNG fuel specifically for high-horsepower (HHP) engines used in drilling rigs, pressure pumping services and heavy-duty highway and off-road trucks, the partners said. Other HHP applications for the LNG supply include rail, mining, and remote power generation. To support the entire LNG supply chain, Encana and Ferus LNG have also designed and are in the process of building specialized mobile storage and dispensing equipment. Ferus and Encana said they have committed to using LNG for their own fueling needs. In 2011 alone, Encana saved $12 million in fuel costs by using natural gas instead of diesel in drilling rigs and company trucks and is on track to exceed this figure in 2012, the company said (see NGI, March 26). Earlier this year Ferus said it was putting into service the first LNG-powered heavy duty truck in Alberta (see NGI, April 30).
Long-haul trucking fleets are increasingly turning to liquefied natural gas (LNG) as a fuel, and with the upcoming availability of larger (12- to 13-liter engines) next year, the U.S. market could eventually reach more than 2 Tcf annually, according to Clean Energy Fuels Corp.’s CEO.
