Where We Work

Chief Oil & Gas is engaged in the exploration, development and production of oil and natural gas reserves in several fields throughout the continental United States.

Marcellus ShaleMarcellus Shale
The Marcellus Shale runs from the southern tier of New York, through the western portion of Pennsylvania into the eastern half of Ohio and through Maryland and West Virginia. Scientists estimate that the Marcellus Shale holds 500 trillion cubic feet of clean natural gas. If even 10 percent is recovered, it could supply America's natural gas needs for 2 years, significantly reducing the nation's dependence on foreign energy sources. Shale drilling is a safe, effective and environmentally sound way to produce clean-burning natural gas. Read More.
