Environmental Aspects

The primary objective of this project is to provide information on the volume, quality, impacts, and possible uses of water produced during generation and development of energy resources (particularly hydrocarbons) as well as related fluids injected into reservoirs for energy development and associated waste disposal. The purpose of this work is to address scientific and societal questions...

The AGGER project’s purpose is to advance the understanding of geologic energy sources, generation, composition, movement, and production potential, including resource recovery from energy wastes.

Carbon Dioxide (CO2) is utilized by industry to enhance oil recovery. Subsurface CO2 storage could significantly impact reduction of CO2 emissions to the atmosphere, but the economics and potential risks associated with the practice must be understood before implementing extensive programs or regulations. Utilization of other energy-related gases such as helium (He), if separated and concentrated...

Work in this task of the Oil and Gas Waters Project focuses on quantifying the water used during hydrocarbon development and the water produced along with oil and gas. Hydraulic fracturing is an integral part of oil and gas development in many areas, and water use for this purpose has increased considerably in the last decade. Water produced from petroleum reservoirs includes hydraulic fracturing...

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.

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)...

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...

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...

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.

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...

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 (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...
