Seneca Boasts First 100% LNG-Powered Drill Rig in Marcellus

EQT was the first driller in the Marcellus Shale to convert a drilling rig to run on electricity produced by LNG, or “liquefied natural gas” (see this MDN story). CONSOL has also been experimenting with converting some of their rigs to use LNG too (see this MDN story). You may now add a third driller to the list: Seneca Resources. Seneca is the gas drilling arm of National Fuel Gas Company.

Yesterday, Seneca announced they are converting two of their rigs to run on LNG. But unlike EQT and CONSOL which mix LNG with diesel fuel in a blend, Seneca is using 100% LNG to power their rigs—a first for drilling rigs in the Marcellus Shale. Seneca says they’ve already converted one rig that’s now in operation, a second rig will be finished in November, and a third rig is coming later this year. Seneca also says someday they’d like to use the gas coming out of the ground to power the rig that’s drilling it. Cool.
