Shows where there are potential commercial sources of natural gas trapped in formations with very low permeability to gas (not necessarily shale units). Hydraulic fracturing might be needed in order to exploit these resources.
Regional studies mapping the seafloor sedimentary character and assessing marine sand and gravel resources around the United States, to inform beach nourishment and coastal restoration, benthic habitat and sediment transport studies
This study reconstructs past interactions among ecosystem factors, native species, and human land use in the Greater Yellowstone ecosystem to provide a context for future management to sustain both ecological and human communities.
Using a performance-based geological assessment methodology, we estimated mean volumes of 1,345 billion cubic feet of potentially technically recoverable gas and 168 million barrels of technically recoverable oil and natural gas liquids here.
