USGS Publication: Fact Sheet 2013–3115A recent U.S. Geological Survey analysis of the Green River Formation of the Piceance Basin in western Colorado shows that about 920 and 352 billion barrels of oil are potentially recoverable from oil shale resources using oil-yield cutoffs of 15 and 25 gallons per ton (GPT), respectively.

USGS Publication: Open-File Report 2013–1257The Oligocene Frio and Anahuac Formations were assessed as part of the 2007 U.S. Geological Survey (USGS) assessment of Tertiary strata of the U.S. Gulf of Mexico Basin onshore and State waters. Estimated total mean values of technically recoverable, undiscovered resources are 172 million barrels of oil (MMBO), 9.4 trillion cubic feet of natural gas (TCFG), and 542 million barrels of natural gas liquids for all of the Frio and Anahuac assessment units.

Outside Publication: Organic Geochemistry
The gas released from coals under hydrous pyrolysis conditions represents a quantifiable mixture of ancient (270 Ma) methane (likely microbial) that was generated in situ and trapped within the rock during the rapid heating by the dike, and modern (laboratory) thermogenic methane that was generated from the indigenous organic matter due to thermal maturation induced by hydrous pyrolysis conditions. These findings provide...

Press Release & Publication
Akutan Volcano hosts a geothermal system that includes a fumarole field at about 400 meters (1312 feet) elevation on the northeast flank of the volcano and a series of hot springs that discharge close to sea level on the northeast side of the island. Numerous industry-led geophysical studies and test drilling in the past few years have proven the existence of a geothermal resource. USGS field studies completed in 2012 suggest that the available geothermal resource may be even larger than previously recognized.

USGS Publication: Open-File Report 2013–1307
We used Rock-Eval pyrolysis and vitrinite reflectance to examine the petroleum source potential of rock samples from the Sheep Creek 1 well in the Susitna basin of south-central Alaska. The results show that Miocene nonmarine coal, carbonaceous shale, and mudstone are potential sources of hydrocarbons and are thermally immature with respect to the oil window.

Outside Publication: Environmental and Ecological StatisticsHere we apply a Tucker3 model on centered log-ratio data to find low dimensional representation of latent variables as a means to simplify data processing and interpretation of three years of seasonal compositional groundwater chemistry data for 14 wells at a study site in Wyoming, USA.
