Stocks of naturally formed hydrocarbon gases which are usually associated with petroleum fields. Useful for heating, they are principally methane, but can be ethane, butane, or propane.
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.
This updated global inventory reports on natural gas hydrate recovered or inferred from geophysical, geochemical, or geological evidence. Includes links to world location maps, inventories, references and posters. Also in PDF format files.
Investigation of the upper- and middle continental slope of the Mississippi Canyon, including the Gulf of Mexico, for the distribution of gas-hydrate deposits with links to a DEM image map, bathymetry data, and research technology.
Quantifies the landscape changes and consequences of natural gas extraction by digitizing indications of disturbance on NAIP aerial photographs and using these with the NLCD to show land use-land cover change.

Distribution and characteristics of natural oil and gas seeps in California, including processes of formation and effects on the environment; with discussion of tar pits and asphaltum.
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.
