Naturally occurring hydrocarbons, typically fluid or gas, often of economic use. Includes oil, natural gas, and asphaltic compounds found in tar sands and oil shales.
Review of flow rate estimates of the Deepwater Horizon oil spill [ More info] We assess the degree to which a consensus was reached on the flow rate of the well by comparing in situ observations with a time-dependent flow rate model derived from pressure readings taken after the Macondo well was shut in for the well integrity test.
Science supporting Gulf of Mexico oil-spill response, mitigation, and restoration activities-Assessment, monitoring, mapping, and coordination [ More info] Explains and shows data and expertise we were able to provide to Federal agencies and decision makers to help them deal with this difficult situation.
Shoreline surveys of oil-impacted marsh in southern Louisiana, July to August 2010 [ More info] Locations of survey points, a photographic record of each site, field observations of vegetation cover and descriptions of oil coverage in the water and on plants, including measurements of the distance of oil penetration from the shoreline.
USGS responds to Deepwater Horizon oil spill [ More info] Imagery, sampling information, and other data intended for use in assessing and remediating environmental problems related to the oil spill in the Gulf of Mexico in 2010
An evaluation of the science needs to inform decisions on Outer Continental Shelf energy development in the Chukchi and Beaufort Seas, Alaska [ More info] We need refined regional understanding of climate change, effective oil-spill risk assessment, preparedness, and response, an analysis of cumulative effects (natural and human), better geospatial data for the area, in an integrated approach.
Assessment of Gas Hydrate Resources on the North Slope, Alaska, 2008 [ More info] We estimate that there are about 85 trillion cubic feet (TCF) of undiscovered, technically recoverable gas resources within gas hydrates in northern Alaska.
Assessment of potential shale gas resources of the Bombay, Cauvery, and Krishna-Godavari Provinces, India, 2011 [ More info] Using a performance-based geologic assessment methodology, we estimated a technically recoverable mean volume of 6.1 trillion cubic feet of potential shale gas in these areas.
Assessment of potential unconventional Carboniferous-Permian gas resources of the Liaohe Basin eastern uplift, Liaoning Province, China, 2011 [ More info] We estimated a mean of 448 billion cubic feet of potential technically recoverable unconventional natural gas in this area.
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.
