First use of natural gas to power equipment for hydraulic fracturing in northeastern Pennsylvania
SUSQUEHANNA COUNTY -- For the first time in northeastern Pennsylvania, field gas from the Marcellus shale has been used to fracture wells via dual-fuel technology, said Cabot Oil & Gas. The process of using clean-burning natural gas can displace up to 70% of the diesel fuel traditionally used to operate fracturing equipment. This successful effort was a partnership with FTS International (FTSI) and Caterpillar Global Petroleum.
The use of dual-fuel technology, where the engines operate on a mixture of natural gas and a small portion of diesel, can reduce air emissions by reducing diesel usage, reduce diesel-carrying truck traffic to well sites, and reduce fuel costs by moving from diesel to natural gas.
In order to operate using natural gas, FTSI' s mobile pressure pumping unit at the site was retrofitted with a Dynamic Gas Blending (DGB) kit from Caterpillar. The system enables substitution of diesel fuel with natural gas during high-pressure pumping operations, and is compatible with field gas, compressed natural gas (CNG) and liquefied natural gas (LNG).
