Gas

The results of all USGS oil and gas resource assessments by a USGS assessment team are subject to a scientific peer review process prior to publication; however, the volumes determined by the assessment process are not subject to approval by higher-lev
During 2010 and early 2011, the USGS examined the Devonian Marcellus Shale in the Appalachian Basin of the eastern United States using the National Oil an
The objective of the 2011 oil and gas resource assessment was to estimate the volume of undiscovered, technically recoverable oil and natural gas resources in the Marcellus shale of the Appalachian basin.  There was no other objective to this study.  T
The objective of the 2011 oil and gas resource assessment was to estimate the volume of undiscovered, technically recoverable oil and natural gas resources in the Marcellus shale of the Appalachian basin.  There was no other objective to this study.
The USGS did not assess water-borne or atmospheric emissions during its 2011 oil and gas resource assessment of the Marcellus.
Gas hydrates can be studied in the laboratory, where a machine is used to create the proper pressure and temperature conditions for hydrate formation, or it can be studied in situ using seismic data collected aboard ships and geophysical models.
The USGS shale gas resource assessments place the 2011 three Marcellus assessment units in fourth, twenty-first, and twenty-third place in a field of twenty-six U.S.
We are unable to predict a time frame for possible production of any of the volumes we mention in our fact sheet but it is likely to be many decades.
The USGS does not maintain statistics on oil production or information on consumption.  However, production information can be obtained from publicly available sources like the North Dakota Depart
