The Marcellus Shale and Point Pleasant-Utica Shale formations of the Appalachian Basin contain an estimated mean of 214 trillion cubic feet of undiscovered, technically recoverable continuous resources of natural gas, according to new USGS assessments.
This is a significant increase from the previous USGS assessments of both formations. In 2011, the USGS estimated a mean of 84 trillion cubic feet of natural gas in the Marcellus Shale, and in 2012 the USGS estimated about 38 trillion cubic feet of natural gas in the Utica Shale.
“Since our assessments in 2011 and 2012, industry has improved upon their development techniques for continuous resources like the shale gas in the Appalachian Basin,” said Walter Guidroz, program coordinator for the USGS Energy Resources Program. “That technological advancement, plus all of the geological information we’ve gained from the last several years of production, have allowed us to greatly expand our understanding of these formations.”
