Fracking WITH Natural Gas

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.
