Advancements in Geochemistry and Geomicrobiology of Energy Resources (AGGER)
Active
By Geology, Energy & Minerals Science Center
May 23, 2022
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.
This purpose manifests in three broad objectives:
- Assessing subsurface microorganisms in order to stimulate or retard biogenic gas production;
- Linking macroscale geologic energy phenomena (e.g., petroleum recoverability or carbon sequestration) to nanoscale parameters (e.g., pore accessibility); and
- Developing standardized approaches to evaluate both the resource potential and environmental risks of energy related wastes.
Achieving these objectives informs Congress, State and Federal agencies, private organizations, and the public on the U.S. energy endowment.
The AGGER project is currently divided into 7 research tasks, detailed below, and funds three research laboratories.
- Controls on microbial methanogenesis in shale deposits and strategies for enhancement - Task leads: Elliott Barnhart and Matthew Varonka
- Structure and composition of energy materials - Task lead: Aaron Jubb
- NORM products, byproducts and wastes from energy resource life cycles - Task lead: Bonnie McDevitt
- Spectroscopic investigations of energy materials - Task lead: Aaron Jubb
- Remote sensing techniques to quantify energy resources in wastes at abandoned mines - Task lead: Bernard Hubbard
- Scoping innovative approaches in advanced field measurements and data analysis - Task lead: Elisha ‘Eli’ Moore
- Assessing critical minerals and contaminants in coal mine drainage - Task lead: Bonnie McDevitt
The following 3 laboratories are associated with the AGGER project:
- Eastern Energy and Environmental Laboratory (EEEL)
- Raman Spectroscopy Laboratory (RSL)
- Naturally Occurring Radioactive Material Laboratory (NORM)
The data releases listed below are associated with the AGGER project.

Chemistry Data from the Birney Test Site, Montana, 2018-2020 Chemistry Data from the Birney Test Site, Montana, 2018-2020
Data were collected to monitor geochemistry before and after an injection designed to stimulate microbial methanogenesis in the shallow Flowers-Goodale coal bed, near Birney in southeastern Montana. Waters from wells completed in the Flowers-Goodale, Nance, Knobloch, and Terret coalbeds at the Birney Test Site were sampled. Geochemical characterization of the water included non-purgeable...
Microbiology of the Utica Shale Microbiology of the Utica Shale
In order to determine the innate microbial community of shale gas reservoirs and how they are impacted by hydraulic fracturing, this study analyzed biomass collected from produced water and rock from hydraulically fractured wells in the Utica Shale. The samples include rock chips from a drill core from one Utica well, produced water from that same Utica well, and produced water from 12...
Atomic Force Microscopy-based Infrared Spectroscopy Data within Immature Eagle Ford Shale at the Nanometer-scale Atomic Force Microscopy-based Infrared Spectroscopy Data within Immature Eagle Ford Shale at the Nanometer-scale
The nanoscale molecular composition of kerogen is a challenging parameter to characterize given the chemical and structural complexity exhibited by this important biopolymer. However, kerogen composition will strongly impact its reactivity and so is a critical parameter to understand petroleum generation processes during kerogen catagenesis. The recent advent of tip-enhanced analytical...
Fluorescence spectroscopy of ancient sedimentary organic matter via confocal laser scanning microscopy (CLSM) Fluorescence spectroscopy of ancient sedimentary organic matter via confocal laser scanning microscopy (CLSM)
Fluorescence spectroscopy via confocal laser scanning microscopy (CLSM) was used to analyze ancient sedimentary organic matter, including Tasmanites microfossils in Devonian shale and Gloecapsomorpha prisca (G. prisca) in Ordovician kukersite from North American basins. We examined fluorescence emission as a function of excitation laser wavelength, sample orientation, and with respect to...
Injection of Deuterium and Yeast Extract at USGS Birney Field Site, Powder River Basin, Montana, USA, 2016-2020 Injection of Deuterium and Yeast Extract at USGS Birney Field Site, Powder River Basin, Montana, USA, 2016-2020
Subsurface microbial (biogenic) methane production is an important part of the global carbon cycle and has resulted in natural gas accumulations in many coal beds worldwide. Laboratory experiments indicate coal beds can act as natural geobioreactors and produce additional low carbon renewable natural gas with algal or yeast compounds, yet the effectiveness of these nutrients in situ are...
Input Files and Code for: Machine learning can accurately assign geologic basin to produced water samples using major geochemical parameters Input Files and Code for: Machine learning can accurately assign geologic basin to produced water samples using major geochemical parameters
As more hydrocarbon production from hydraulic fracturing and other methods produce large volumes of water, innovative methods must be explored for treatment and reuse of these waters. However, understanding the general water chemistry of these fluids is essential to providing the best treatment options optimized for each producing area. Machine learning algorithms can often be applied to...

Thermal evolution of graptolite and solid bitumen properties at high maturity under natural and artificial conditions Thermal evolution of graptolite and solid bitumen properties at high maturity under natural and artificial conditions
To refine the use of graptolite and solid bitumen as thermal proxies at overmature conditions, we evaluated their evolution via Raman and infrared (IR) spectroscopies, reflectance, and geochemical screening using high-temperature pyrolysis experiments in comparison to naturally matured samples. Naturally matured samples included marine shales from the overmature Upper Ordovician Wufeng...

Algal amendment enhances biogenic methane production from coals of different thermal maturity Algal amendment enhances biogenic methane production from coals of different thermal maturity
The addition of small amounts of algal biomass to stimulate methane production in coal seams is a promising low carbon renewable coalbed methane enhancement technique. However, little is known about how the addition of algal biomass amendment affects methane production from coals of different thermal maturity. Here, we show that biogenic methane can be produced from five coals ranging in...

Mapping ancient sedimentary organic matter molecular structure at nanoscales using optical photothermal infrared spectroscopy Mapping ancient sedimentary organic matter molecular structure at nanoscales using optical photothermal infrared spectroscopy
Elucidating the molecular structure of sedimentary organic matter (SOM) is key to understanding petroleum generation processes, as well as ancient sedimentary environments. SOM structure is primarily controlled by biogenic source material (e.g., marine vs. terrigenous), depositional conditions, and subsurface thermal history. Additional factors, e.g., strain, may also impact the...

A global perspective on bacterial diversity in the terrestrial deep subsurface A global perspective on bacterial diversity in the terrestrial deep subsurface
While recent efforts to catalogue Earth’s microbial diversity have focused upon surface and marine habitats, 12–20 % of Earth’s biomass is suggested to exist in the terrestrial deep subsurface, compared to ~1.8 % in the deep subseafloor. Metagenomic studies of the terrestrial deep subsurface have yielded a trove of divergent and functionally important microbiomes from a range of...

Assessment of resource potential from mine tailings using geostatistical modeling for compositions: A methodology and application to Katherine Mine site, Arizona, USA Assessment of resource potential from mine tailings using geostatistical modeling for compositions: A methodology and application to Katherine Mine site, Arizona, USA
The mining industry, in most cases, targets a specific valuable commodity that is present in small quantities within large volumes of extracted material. After milling and processing, most of the extracted material and the effluents are stored as waste (tailings) in impoundments, such as dams or waste dumps, or are backfilled into underground mines. In time, tailing materials may become...
