Brief summaries of USGS projects in Texas including water quality monitoring, digital mapping, energy resources, U.S.-Mexico border mapping, fish and wildlife health, Kemp's Ridley sea turtle, and conditions affecting water quality.
Description of the Denver Organic Geochemistry Laboratory where chemical and geological data is used to research the physical and chemical processes of hydrocarbon generation, migration and accumulation, with links to programs, personnel, and products.
Part A of a complex report on the results of ROCK-EVAL and vitrinite reflectance analysis of a large sample base from more than 70 wells located in three oil-rich California petroleum basins in order to study the formation of oil deposits.
Part B of a complex report on the results of geochemical analysis of 75 shale samples from the Los Angeles, Ventura, and San Joaquin Basins to gather observations relevant to exploration regarding the formation of oil deposits in these basins.
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.
Database provides information on petroleum reservoirs, type and abundance of constituents dissolved in produced water, geochemical reactions between the water and rock, hydrology and geologic, spatial distribution of petroleum production areas.
Report on a community of microscopic organisms, Archaea, found deep in an Idaho hot spring living on hydrogen and carbon dioxide that could possibly exist on other planets. Includes links to related studies, investigators, and microbiology.
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.
Overview of volcano hazards in California with links to monitoring data including earthquakes and deformations, long-term outlook, volcano hazards in the area, USGS response plan, image gallery, monitoring and topical studies, publications and references.
The Marcellus shale is a black shale unit in the eastern US. It has economic use as a source of natural gas. Environmental concerns arising from the process of exploiting this resource include water supply and wastewater disposal.
How will the increasing use of wind turbines affect populations of wild birds and bats? This shows which birds and bats we study, and the aspects of their ecology that may be affected by wind energy development.
World Petroleum Assessment 2000 estimates of the quantities of conventional oil, gas, and natural gas liquids outside the United States that have the potential to be added to reserves in the next 30 years (1995 to 2025).
