HOUSTON, Nov. 26, 2012 /PRNewswire/ -- Baker Hughes Incorporated (NYSE: BHI),
through its subsidiary Baker Hughes Oilfield Operations, has converted a fleet
of its Rhino™ hydraulic fracturing units to bifuel pumps as a way to improve
operational efficiency, lower costs, and reduce health, safety and
environmental impacts.

The new pumps use a mixture of natural gas and diesel, reducing diesel use by
up to 65 percent with no loss of hydraulic horsepower. The converted fleet,
which meets all U.S. Environmental Protection Agency emissions standards, also
can reduce a number of emissions including nitrogen oxides, carbon dioxide and
particulate matter.

Baker Hughes first converted a small fleet of its units in Canada. When
results there were successful, the decision was made to convert an entire
fleet in the United States. The global oilfield services company is in the
process of converting several more fleets of Rhino trucks to Rhino Bifuel
equipment. Additionally, Baker Hughes has a test program in Oklahoma, where a
number of light-duty vehicles have been converted to natural gas.

"Baker Hughes has seen excellent results with this initiative," said Mike
Davis, Baker Hughes' President of Pressure Pumping for U.S. Land. "The
environmental benefits are significant. We're reducing emissions from the
engines driving the stimulation pumps and less fuel is needed to keep our
pumps going. In addition, this has the added value of improving job site
safety by eliminating re-fueling demands during operations."

Using the converted Rhino Bifuel units, Baker Hughes recently completed a
hydraulic fracturing job in the Eagle Ford Shale for Cheyenne Petroleum
Company. Cheyenne was interested in using some of the converted units given
the potential savings by cutting diesel consumption, as well as the long-term
reduction in emissions. Baker Hughes was able to pump 35 stages using three of
the converted Rhinos during each stage. Throughout the job, Baker Hughes saw a
65 percent substitution (diesel fuel was replaced with liquefied natural gas)
rate with no loss of horsepower. By substituting natural gas into the
converted diesel engine, the bifuel alternative can operate twice as long as
engines running solely with the on-board diesel.

"The use of the converted Rhino Bifuel units was transparent during the job,"
said Greg Presley, Cheyenne Petroleum Company's Senior Operations Engineer.
"The job pumped the same as a 100% diesel job with many environmental
