Appalachian area natural gas producer EQT Corporation launched a pilot program to begin converting drilling rigs to liquefied natural gas (LNG), displacing the diesel used to power equipment at the well site. This program marks the first LNG rig conversion in the Marcellus Shale and will provide a cleaner burning alternative fuel for the region’s drilling operations.
The LNG being used for EQT’s pilot program is produced locally from Marcellus natural gas reserves. EQT’s initial rig conversion is now operating in Northern West Virginia; pending evaluation of the pilot program, the company hopes to convert additional rigs in West Virginia and Pennsylvania.
Compared to diesel, natural gas emits between 20% and 30% less carbon dioxide and has a fraction of the emissions of nitrogen oxides, sulfur oxides, and particulates.
