Seneca Resources Announces Plan to Convert Marcellus Drilling Rigs to Natural Gas

Seneca Resources Corporation ("Seneca"), the wholly-owned exploration and production subsidiary of National Fuel Gas Company NFG ("National Fuel" or the "Company") today announced plans to complete the conversion of two of its Pennsylvania drilling rigs to cleaner-burning natural gas, displacing the diesel fuel currently used to power equipment at the well site. These will be the first dedicated 100 percent liquefied natural gas (LNG)-fueled drilling rigs operating in the Marcellus Shale within Pennsylvania. The first rig was converted earlier this month in Lycoming County. The conversion of a second rig should be completed in early November. Seneca will also deploy a third rig that will run on both diesel and natural gas during this fiscal year.
