New Dual-Fuel Technology Offers Environmental and Cost Benefits
HOUSTON--(Business Wire)--
Halliburton (NYSE: HAL), Apache Corporation and Caterpillar have developed
innovative dual-fuel technology capable of safely and efficiently powering the
pumping equipment used for fracturing treatments with a mixture of natural gas
and diesel. With 12 pumps (24,000 horsepower), this is one of the largest-scale
dual-fuel projects ever conducted in the oil and gas industry. 

G. Steven Farris, Chairman and CEO of Apache and the Chairman of America`s
Natural Gas Alliance (ANGA), encouraged Apache and the industry to increase the
use of natural gas as a fuel for engines. In response, Halliburton developed a
technical solution for converting the pumping equipment used at a typical
large-scale fracturing spread to a dual-fuel system including natural gas - one
that would be more efficient and cleaner-burning than using diesel alone. 

Halliburton and its supplier, Caterpillar, teamed up to convert the company`s
new Q-10 pumps to dual fuel with a technology that would safely and efficiently
accommodate high-quality liquefied or compressed natural gas. Collaborating
closely with Halliburton and Apache to cover a wide range of performance,
environmental and efficiency criteria, Caterpillar adapted its proprietary
Dynamic Gas Blending (DGB) engine technology to power Halliburton`s massive

"We anticipate that in the not-so-distant future, these DGB engines can be
easily retrofitted to efficiently burn available on-site conditioned field gas,
thereby saving operators additional fuel transport costs," said Marc Edwards,
Senior Vice President of Halliburton`s Completion and Production Division. 

Halliburton also worked with Linde North America to establish a safe and
efficient gas distribution system as well as the supply of the liquefied natural
gas needed for this project. 

"Apache is proud to be setting an example for the industry by using a
clean-burning, abundant and inexpensive U.S. energy source in its operations,"
said Mike Bahorich, Apache`s Executive Vice President and Chief Technology
Officer. "Taking advantage of natural gas can lead to cost savings for the
industry and for energy consumers, new jobs and a cleaner environment - it`s
time for us to use this resource to its full potential. We commend Halliburton
for its ability to take on our dual-fuel challenge and quickly make it

Apache has broadened the environmental scope of this project by showcasing at
selected work sites - including the Granite Wash site outside Oklahoma City
where the new dual-fuel technology has debuted - Halliburton`s Frac of the
Future technology. Started in 2010, Halliburton`s Frac of the Future initiative
is designed to address the need to shrink wellsite footprints, improve
environmental performance, cut supply chain costs and enhance the reliability of
the equipment on site. 


Founded in 1919, Halliburton is one of the world`s largest providers of products
and services to the energy industry. With more than 70,000 employees in
approximately 80 countries, the company serves the upstream oil and gas industry
throughout the life cycle of the reservoir - from locating hydrocarbons and
managing geological data, to drilling and formation evaluation, well
construction and completion, and optimizing production through the life of the
field. Visit the company`s website at www.halliburton.com.
