The Geoinformatics Technology Integration (GTI) project develops applications, databases, and other related technologies to assist Geology, Energy & Minerals Science Center (GEMSC) scientists in their research activities and distribution of their data to the public.

Potential reuse waters contained unique mixtures of organic contaminants with the greatest number detected in treated municipal wastewater treatment plant effluent, followed by urban stormwater, and agricultural runoff . This study provided information for decisions on reuse strategies to support freshwater supplies.

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.

Since its establishment in 1879, USGS geoscientists have investigated the geochemistry of energy resources. Research conducted in the Geochemistry of Energy Fuels project continues this tradition. Goals include 1) understanding the geologic, geochemical, microbiological, and other factors that control production, quality, and composition of coal, petroleum, and nuclear fuels, and 2) predicting the...

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...

This task conducts research to characterize or evaluate the economics of developing technologies or markets in geologic resources. Such research can analyze the relative risks, costs, and benefits from the utilization and not just the extraction of underground resource. Economic analysis builds upon the geologic resource assessment work by other tasks in the Utilization of Carbon and other Energy...

The United States (U.S.) domestic energy supply increasingly relies on natural gas and renewable sources; however, their efficient use is limited by supply and demand constraints. For example, a) in summer, natural gas production may outpace home heating fuel demand and b) in daytime, wind and solar electricity production may outpace industrial power requirements. Storing rather than dumping...

The primary objectives of this one-year scoping project are to determine the feasibility of extracting byproduct mineral commodities, such as critical minerals, from mine tailings. We plan to analyze the existing data and reports from an active mine site on the composition of their mill tailings pile, and collect preliminary reconnaissance samples to identify appropriate analytical techniques that...

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...

Geologic and geochemical processes that impact fuel quality, quantity, and availability can be best understood by utilizing a range of approaches, including, but not limited to isotopic signatures, inorganic and organic analyses, and neutron scattering techniques. Current work focuses on using neutron scattering to understand how fluids are stored and flow through tight continuous reservoirs and...

Funded by the USGS Energy Resource Program “Shark Tank” grant. The goal of this project is to develop a method to use remotely collected satellite and airborne data to ascertain the quantity and quality of waste at abandoned uranium mines to better estimate the resource potential, identify abandoned mines and explore potential applications to other energy resources. This is a collaborative effort...

The gas emission zone liberates and accumulates significant amounts of coal mine methane as a by-product of active mining. In most active mines, coal mine methane is controlled by wellbores, called gob gas ventholes. Despite the presence of these wellbores, it is not possible to capture all of the methane generated within the gas emission zone. As a consequence, a large amount of gas migrates into...
