LAFAYETTE, La., Jan. 2, 2013 /PRNewswire/ -- Green Field Energy Services
(GFES), in conjunction with Apache Corporation, performed the first-ever
operation of a Frac Pump utilizing field gas as its sole fuel source.

The GFES Turbine Frac Pump was rigged up to a production well in the Granite
Wash Field located in the Texas Panhandle and powered 100% by natural gas
produced in the field. Typical North American fracturing rates and pressures
were achieved in a simulated frac job, while maximizing fuel economy and
maintaining full pump performance.

The simple field hook-up took natural gas from a producing well on the same
location 150 feet from the Frac Pump, routed it through the field production
units, through a GFES Natural Gas Conditioning Unit, then directly to the
Turbine Frac Pump. The Turbine Frac Pump then pumped fluid from one frac tank
to another, allowing the Company to measure rates, pressures and other
important operations metrics.

Rick Fontova, President of Green Field Energy Services, stated, "This is a
significant milestone both for Green Field Energy Services and the industry.
To be able to completely power our fracturing pumps on field gas is
outstanding and moves us one step further in our gasification vision.

"Natural gas is plentiful and far more economic as a fuel source for our pumps
than traditional diesel fuel and produces far fewer air emissions than
diesel. We are very pleased with the success of this frac simulation and we
are now ready to use 100% natural gas to drive our entire frac spread,"
Fontova said.

"This operation was a major accomplishment," added Mike Bahorich, Executive
Vice President and Chief Technology Officer of Apache. "The Green Field team
demonstrated their turbine fracturing technology and ran their pumps on 100%
field gas.This is an important accomplishment in the path towards using
natural gas as a fuel source in hydraulic fracturing operations, which is a
major initiative for Apache."

Green Field Energy Services is the only fracturing services provider using
turbine driven frac pumps that have the capability of operating on 100%
natural gas.
