Big Data and Data Visualization
In the “Big Data and Data Visualization” task of the Oil and Gas Waters Project, we compile and update the USGS National Produced Waters Geochemical Database and use big data approaches to provide stakeholders with effortless access and modern tools for easier use and interpretation of our data.
Characterization and Reuse of Oil and Gas Waters
In the “Characterization and Reuse of Oil and Gas Waters” task of the Oil and Gas Waters Project, we collect new water samples from conventional and hydraulically fractured unconventional plays in high priority oil and gas basins and use the geochemistry of water produced along with oil and gas (a) as a tool to interpret deep basin fluid flow and to fingerprint brines from specific reservoirs, (b)...
Induced Seismicity Associated with Carbon Dioxide Geologic Storage
As a national science agency, the USGS is responsible for assessing hazards from earthquakes throughout the United States. The USGS studies induced seismicity across the spectrum of energy issues: carbon sequestration, geothermal energy, and conventional and unconventional oil and gas. In the central and eastern United States, earthquakes induced by fluid injection activities contribute...
Geologic Carbon Dioxide and Energy-related Storage, Gas Resources, and Utilization
The objectives of this task are to conduct relevant research needed to 1) evaluate helium (He) and CO2 resources; 2) support future assessments of low-thermal gases and better understand their resources and potential for use as analogues for anthropogenic CO2 storage; 3) study the feasibility of large-scale CO2 mineralization in the United States; 4) develop pressure-limited dynamic models for...
Methodology Development and Assessment of National Carbon Dioxide Enhanced Oil Recovery and Associated Carbon Dioxide Storage Potential
The objective of this research task is to conduct a national assessment of recoverable oil related to CO2 injection. The amount of CO2 stored (utilized) during the hydrocarbon recovery process will also be evaluated.
Molecular Fingerprinting of Energy Materials
The chemical composition of complex solid organic matter (OM) from sedimentary reservoirs is a key parameter in the generation of hydrocarbon fuels. Vibrational spectroscopies such as Fourier transform infrared (FTIR) and Raman have been widely applied to understand the molecular make-up of these hydrocarbon precursors, as well as provide links to their thermal histories via correlation to proven...
NORM Byproducts of Energy Resources
Naturally Occurring Radioactive Material (NORM) is found in waste produced during the extraction of uranium, phosphate, rare earth elements (REE), coal, oil and gas resources. The focus of this effort is to understand the potential for byproduct recovery of U-235 and Th-232, the fissionable isotopes used to generate nuclear energy from wastes produced during energy resource development. The NORM...
Byproducts of Energy Fuels
This task provides detailed information on the use and resource potential of energy by-products, as well as controls on the potential mobility of contaminants resulting from transport, storage, and disposal of these byproducts. Specific topics investigated include 1) transport and fate of organic and inorganic contaminants during storage and disposal of waste coal and coal combustion byproducts...
Microbial Methanogenesis and Strategies for Enhancements
Microbial (biogenic) natural gas is present in shale, coal and petroleum reservoirs and is estimated to account for 20% of the world’s natural gas resources. We provide hydrological, geochemical and microbial information related to the production of biogenic natural gas and new methods to monitor and enhance the production of this energy resource. Generating microbial methane at a faster rate from...
Maps of Energy Occurrence
The primary objective of this task is to produce digital maps coal-bearing areas and related energy sources and materials of the U.S., and internationally. The approach for creating GIS representations of energy sources of the U.S. and the world is to use existing geologic GIS data where possible, supplemented by data on location, rank and age from published maps and reports. Each GIS database...
Trace Elements in Energy Fuels
In this task we conduct new interpretive studies of the concentration and distribution of trace metals and mercury in coal and other energy materials. Complementary studies of coal combustion products are conducted under Task 8. Together with use of existing USGS databases, we examine the potential for reducing emissions of potentially toxic substances by coal preparation, and by optimizing coal...
Controls on Unconventional Oil and Gas Production
This scoping task incorporates insights from new approaches to production of unconventional resources and currently focuses on conducting a pilot assessment of biogenic natural gas resources in the Permian Basin. For the pilot assessment to occur, we are developing a database that will host geochemical parameters known to be suggestive of microbial methanogenesis mined to the reservoir level for...
