The Marcellus Shale | December 2021
Field Overview
The Marcellus Shale is the largest gas play onshore in the US. Located in the Northeast, it supplies the high-demand markets along the East Coast. Most of the basin’s gas is produced through unconventional methods, while the little oil produced is mostly by conventional means. Some of the top formations include the Onondaga and the Huntersville.

Basin Highlights
Permits to Drill New Shale Wells in PA Hit 13-Year Low in November
34 permits for wells were issued in November 2021, the lowest amount since November 2008, nearly 13 years prior. The shale boom of 2010 peaked in December with a total of 402 permits issued in the span of one month. The top producers in the Marcellus kept spending and drilling low while bringing in cash on the back of higher commodity prices.
Utica/Marcellus Gas Production Expected to Increase in January
The U.S. Energy Information Administration released a report on the Marcellus and Utica shale showing an increase in production to kick-off 2022. According to the EIA’s estimate, a 78 million cubic feet per day increase can be expected in the two shale regions. Hilcorp Energy Co. has been busy filing applications to deepen existing wells and drill new ones in Columbiana County. EAP Ohio has also filed applications for similar reasons. Not only does the EIA expect gas production to increase in the Appalachian region, but oil production too, by an estimated 1,000 barrels a day in January.
Pa. releases final rule to cut methane leaks from existing oil and gas well sites
A Pennsylvania methane-reduction strategy took a step forward when regulators finalized a new set of rules in early December. The new rules will require operators to perform four leak checks per year per well on those considered low-producing and replace old hardware that doesn’t comply with new low-leak standards. Storage tank standards will also become stricter under the new rules which require tanks to meet higher emissions standards.
