Assessment of Undiscovered Biogenic Gas Resources, North-Central Montana Province [More info]: We estimated 6,192 billion cubic feet of shallow biogenic (continuous) undiscovered gas in this area using a geology-based assessment methodology.
Assessment of Undiscovered Hydrocarbon Resources of the Western Oregon and Washington Province [More info]: We estimated mean volumes of 2.2 trillion cubic feet (TCF) of undiscovered natural gas and 15 million barrels of oil (MMBO) in the using a geology-based assessment methodology.
Assessment of Undiscovered Natural Gas Resources of the Sacramento Basin Province of California, 2006 [More info]: We estimated undiscovered, technically recoverable resources are 534 billion cubic feet of natural gas and 323 thousand barrels of natural gas liquids in this area using a geology-based assessment methodology.
Northern Gulf of Mexico ecosystem change and hazard susceptibility [More info]: Map interfaces and data in the area offshore Louisiana, Mississippi, and Alabama which was affected most by hurricane Katrina and, more recently, the oil spill.
Thermal Properties of Methane Gas Hydrates [More info]: This unusual form of hydrocarbons can alter the thermal properties of host sediments; the analysis presented here helps us understand how those sediments might behave under natural or human-induced changes in the environment.
