Oil & Gas Journal is reporting:
Cabot Oil & Gas Corp. said it is using natural gas from the
Marcellus shale in Susquehanna County, Pa., to fracture wells via
dual-fuel technology in a process that can displace as much as 70% of
the diesel fuel traditionally used to operate hydraulic fracturing
equipment.
The dual-fuel technology involves engines operating on a mixture of
natural gas and diesel. The effort was a partnership with FTS
International (FTSI) and Caterpillar Global Petroleum, Cabot said.
Benefits are said to include:
• Reduced air emissions for a cleaner environment, due to a reduction in diesel usage.
• 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.
• Reduced costs, as natural gas can be a less expensive fuel option
than diesel, providing potential cost savings for industry and
consumers.
