Thermal Indices Innovation Project

The presence of an interconnected organic nano-porosity network has emerged as an important control on reservoir permeability and hydrocarbon storage space in shale petroleum systems. Application of SEM techniques to Ar ion-milled rock surfaces has become standard industry practice for identification of organic pore systems and mudstone reservoir characterization. There is general consensus...

Hydrous Pyrolysis and Kerogen Conversion

Vitrinite suppression/retardation, and the misidentification of solid bitumen as vitrinite, can lead to large variance in measurements of reflectance, cause trends with respect to depth that are difficult to explain by any known geologic phenomena, and cause problems in evaluation of thermal histories and timing of petroleum generation. Accordingly, experimental identification and...

Standardization of Petrographic Measurements

Advent of the "shale revolution" since about 2005 has caused increased demand for reliable petrographic measurements of thermal maturity in shale via vitrinite reflectance, long considered the "gold standard" approach (Hackley et al., 2015). A standardized methodology for organic reflectance measurement in shale first became available in 2011 (ASTM, 2016), based on prior work by task members....

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...

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...

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...

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...

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...

Geochemistry of Energy Fuels Project

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)...

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...

Trace Levels of Organic Chemicals Limited to Local Reaches of a Stream near an Oil and Gas Wastewater Disposal Facility

Organic contaminants that were present in Wolf Creek near a wastewater disposal facility were not evident farther downstream where Wolf Creek enters the New River. Wolf Creek and the New River are used for drinking water and recreational purposes.
