Cabot Oil & Gas Corporation (COG): How This Company Is Using Natural Gas in Fracking

Cabot Oil & Gas Corporation (NYSE:COG), a leading independent natural gas producer with significant operations in the Marcellus, recently announced that it is using natural gas from the Marcellus to fracture wells via an innovative dual-fuel technology.

The use of this exciting technology, which uses engines that operate on a mixture of both natural gas and diesel, may help reduce the use of diesel — the traditional fuel of choice to operate hydraulic fracturing equipment — by as much as 70%.

Cabot Oil & Gas Corporation (NYSE:COG)’s efforts mark the first time “field” gas has been used in northeastern Pennsylvania for this purpose. In developing and implementing the dual-fuel technology, the Houston-based company partnered with FTS International, a leading provider of well completion services for the oil and gas industry, and Caterpillar Inc. (NYSE:CAT) Global Petroleum, the oil and gas division of manufacturing giant Caterpillar .

Cabot Oil and Gas (COG)How the technology works and its benefits
In powering its hydraulic fracturing operations with natural gas, Cabot Oil & Gas Corporation (NYSE:COG) used a mobile pressure pumping unit provided by FTSI, which was then retrofitted with a dynamic gas blending kit from Caterpillar. This system allows diesel to be substituted with natural gas during high-pressure pumping operations and is compatible with field gas, compressed natural gas, and liquefied natural gas.

“Cabot Oil & Gas Corporation (NYSE:COG) is continually searching for ways to utilize cutting-edge, environmentally friendly technology during our operations,” said Cabot President and CEO Dan O. Dinges. “We are already converting our vehicle fleet and currently have a drilling rig using natural gas as well, so the next step is to utilize the technology on a hydraulic fracturing site.”

According to a statement released by the company, dual-fuel technology offers several benefits, including “(1) Reduced air emissions for a cleaner environment, due to a reduction in diesel usage, (2) reduced truck traffic when field gas at or near the well site is used due to a reduction in the transportation of diesel fuel to site, and (3) reduced costs, as natural gas can be a less expensive fuel option than diesel, providing potential cost savings for the industry and for energy consumers.”

Final thoughts
With its foray into dual-fuel technology, Cabot Oil & Gas Corporation (NYSE:COG) joins the likes of Apache Corporation (NYSE:APA), which in January became the first energy exploration and production company to power a full hydraulic fracturing operation using natural gas-burning engines at its Granite Wash operations in Oklahoma. By switching to natural gas, Apache said it expects to reduce fuel costs by roughly 60%, while also lowering emissions.
