GE Engines Powering First LNG-Fueled Drilling Rigs In Marcellus Shale

January 2013, Vol. 240 No. 1

To reduce the environmental impacts and improve the economic performance of their U.S. unconventional gas production activities, energy developer Seneca Resources Corp. and drilling partner Ensign Drilling have installed two of GE’s Jenbacher gas engines to power the first LNG-fueled drilling rigs of their kind in the Marcellus Shale region of Pennsylvania.

Seneca converted the power plants of two existing diesel-powered rigs to use LNG in GE’s 1-megawatt Jenbacher J320 turbocharged natural gas engines. The Jenbacher units were combined with Ensign Drilling-designed rig packages to provide all the electricity needed by each drilling rig. The J320 represents GE’s first U.S. Environmental Protection Agency-certified technology for mobile and stationary drilling applications.
