Halliburton's Frac of the Future

Tools

A new dual-fuel technology has been dubbed "Halliburton's Frac of the Future." It's part of an initiative designed to address the need to shrink well site footprints, improve environmental performance, cut supply chain costs and enhance the reliability of onsite equipment.

The new dual-fuel technology is the result of a collaboration between Halliburton, Apache Corporation and Caterpillar and is hailed as being capable of safely and efficiently powering the pumping equipment used for fracturing treatments with a mixture of natural gas and diesel. The collaboration involves 12 Q-10 pumps (24,000 horsepower) and is one of the largest-scale dual-fuel projects ever seen in the oil and gas industry.

In an effort to increase the use of natural gas as a fuel for engines, 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 -- burning cleaner than using diesel alone.

Caterpillar adapted its proprietary Dynamic Gas Blending (DGB) engine technology to power Halliburton's pumps and worked closely with Halliburton and Apache to cover a wide range of performance, environmental and efficiency criteria,

Taking advantage of natural gas can lead to cost savings for industry and consumers, new jobs and a cleaner environment if used to its full potential.

"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 VPA of Halliburton's Completion and Production Division.
