HOUSTON -- January 11, 2013

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

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 pumps.

“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

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
