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).
