PITTSBURGH and LAFAYETTE, La., Sept. 16, 2013 /PRNewswire/ -- EQT Corporation
and Green Field Energy Services, Inc. today announced the successful
completion of multiple fracturing stages using pumps powered by 100% "field"
gas supplied directly from a nearby Marcellus natural gas well. The hydraulic
fracturing was conducted on a well operated by EQT Corporation and located in
the Marcellus Shale of Pennsylvania.

"We are excited to be one of the first to utilize a technology that allows us
to power our equipment from one of our producing natural gas wells," said
Steve Schlotterbeck, Senior Vice President and President, EQT Exploration &
Production. "We're continually exploring ways to minimize impact to the
environment by making our operations cleaner, greener, and more efficient. By
eliminating diesel and using 100% field gas, we're able to reduce emissions of
carbon monoxide, carbon dioxide, nitrogen, and sulfur oxides; as well as
decrease the amount of truck traffic on local roads."

Rick Fontova, President of Green Field Energy Services, stated, "Green Field
is honored to find a partner in EQT who shares our goal of utilizing 100%
clean burning natural gas for hydraulic fracturing. Our Turbine Frac Pump
technology is unique in that it is capable of running on 100% natural gas,
where others require the use of diesel. In addition, our proprietary Turbine
Frac Pumps meet all of the current EPA Tier IV level emissions standards."

In 2012, EQT launched a pilot program to begin converting drilling rigs to
natural gas, and has commissioned four to date. The first rig operates on
liquefied natural gas (LNG), while the remaining three are powered by natural
gas produced on site.
