Shale gas reserves in the U.S. 2022, by basin

The Appalachian Marcellus basin has the greatest proved reserves of any shale play in the United States. As of 2022, proved natural gas reserves in that area amounted to 153 trillion cubic feet, nearly twice the size of the second-largest shale play in the Permian Basin. Marcellus is responsible for 10 trillion cubic feet in shale gas production per year.

阿巴拉契亚地区的马塞卢斯盆地拥有美国任何页岩气藏中最丰富的已证储量。截至2022年，该区域的已证天然气储量达到153万亿立方英尺，几乎是二叠纪盆地第二大页岩气藏的两倍。马塞卢斯盆地对每年10万亿立方英尺的页岩气产量负有责任。
