WILLIAMSVILLE, N.Y. -- October 25, 2012

Seneca Resources Corporation ("Seneca"), the wholly-owned exploration and
production subsidiary of National Fuel Gas Company (NYSE: 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

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.

"We continually look for opportunities to improve our operations, reduce our
costs and minimize our environmental impact. The use of alternative fuels,
such as LNG and eventually field gas (natural gas produced from local wells
near the drill pad), is just one step in a broader strategic plan to expand
the use of natural gas in our drilling program," said Matthew D. Cabell,
President of Seneca. "This change will help reduce our environmental footprint
and it is also economically beneficial."

Industry studies on the use of natural gas have shown a significant reduction
in carbon dioxide (CO2), volatile organic compounds (VOCs) and nitrogen oxide
(NOX) emissions when compared to diesel. Certain emissions reductions could be
as high as 95 percent. Additionally, the operation of a drilling rig fueled by
natural gas is quieter than one utilizing diesel fuel and is virtually

At a much lower cost than diesel, natural gas-powered drilling rigs offer an
economic benefit to the company. At today's prices, the savings could be as
much as 65 percent. Longer-term, Seneca expects to see additional savings as
rigs are connected to natural gas produced from nearby wells, eliminating the
need to transport LNG to the rig site.

"National Fuel has been a diligent steward of the environment for more than
100 years and Seneca places this as a top operational priority," said David F.
Smith, Chairman and Chief Executive Officer of National Fuel. "Over the past
few years, Seneca has used coal mine drainage water in its drilling program,
instituted a 'zero surface discharge' policy for produced water and embraced
other technology to reduce its environmental footprint. Utilizing natural gas
powered drilling rigs furthers Seneca's long-standing operational excellence.”
