Assessment of undiscovered oil and gas resources of the Devonian Marcellus Shale of the Appalachian Basin Province [More info]

We estimated a mean undiscovered natural gas resource of 84,198 billion cubic feet and a mean undiscovered natural gas liquids resource of 3,379 million barrels using a geology-based assessment methodology.

Assessment of Undiscovered Natural Gas Resources of the Arkoma Basin Province and Geologically Related Areas [More info]

We estimated mean volumes of 38 trillion cubic feet (TCF) of undiscovered natural gas, 159 million barrels of natural gas liquid (MMBNGL), and no oil in accumulations of 0.5 million barrels (MMBO) or larger in this area.

Assessment of undiscovered oil and gas resources of the East Coast Mesozoic basins of the Piedmont, Blue Ridge Thrust Belt, Atlantic Coastal Plain, and New England Provinces, 2011 [More info]

We estimated 3,850 billion cubic feet of natural gas, 135 million barrels of natural gas liquids in this area using a geology-based assessment methodology.

Geology of the Devonian Marcellus Shale--Valley and Ridge province, Virginia and West Virginia--a field trip guidebook for the American Association of Petroleum Geologists Eastern Section Meeting, September 28-29, 2011 [More info]

Detailed background information with descriptions of sites and photos explaining the geology of this organic-rich shale unit that has recently become a significant source of natural gas resources.

Assessment of undiscovered oil and gas resources in Jurassic and Cretaceous strata of the Gulf Coast, 2010 [More info]

We estimated means of 147.4 trillion cubic feet of undiscovered natural gas, 2.4 billion barrels of undiscovered oil, and 2.96 billion barrels of undiscovered natural gas liquids in this area using a geology-based assessment methodology.
