Information on coal on federally owned public lands with links to database and maps for federal coal ownership of the United States, Rocky Mountains and Great Plains, and Colorado Plateau.
The classification system by which coal is classified into resource/reserve base/reserve categories on the basis of the geologic assurance of the existence of those categories and on the economic feasibility of their recovery.
Methane (natural gas), while frequently developed with petroleum, also occurs in association with coal and accounts for about 7.5 percent of U.S. natural gas production. Links to digital publications on coalbed methane.
Geologic CO2 sequestration with enhanced oil recovery in existing hydrocarbon reservoirs can increase the U.S. hydrocarbon recoverable resource volume and prevent CO2 release to the atmosphere.
Online report summarizing the economic analysis of the U.S. Geological Survey's 2002 petroleum assessment of the Federal lands in the National Petroleum Reserve Alaska (NPRA) study area.
Reviews how coal fires occur, how they can be detected by airborne and remote surveys, and, most importantly, the impact coal-fire emissions may have on the environment and human health, especially mercury, carbon dioxide, carbon monoxide, and methane.
Field trip to Powder River Basin coalbed methane (CBM) development areas showing impacts related to drilling, facilities, pipeline networks, access roads, withdrawal, and disposal of co-produced water from CBM wells.
Brief overview of gas hydrates and current research. Site also contains links to related USGS research and publications and web sites of other groups participating in gas hydrate research.
