Christina DeVera is a Physical Scientist with the USGS Eastern Energy Resources Science Center in Reston, VA.
Biography
Christina received a Bachelor of Science degree in Biology concentrating in environmental and conservation science from George Mason University in 2010. Since joining the USGS in 2009, Christina has been a part of numerous research efforts including methanogenesis studies, the CO2 Geologic Sequestration Assessment Project, hydraulic fracturing and effects on human health, studying microbial communities in natural CO2 systems within the United States, and more recently, source rocks in North Slope Alaska. Presently, her research is focused on driving factors of microbial communities within naturally occurring CO2 systems within the United States and gamma ray spectroscopy of source rocks in North Slope Alaska. Christina is also the LIMS Coordinator and Collateral Duty Safety Program Coordinator for EERSC.

Science and Products
Laboratory Information Management System (LIMS) Project
The ERP Laboratory Information Management System (LIMS) Project is responsible for developing, implementing, and managing a LIMS architecture that expands the LIMS capabilities to support ERP laboratory needs for capturing, tracking, reporting, and managing sample and analysis data generated in ERP laboratories as well as data for samples submitted to external laboratories. The LIMS Project ...
Microbial Communities Associated with Hot Springs and other CO2-rich Waters, Rocky Mountain Plateau
The Colorado Plateau is associated with several different commercial sources of natural CO2 and other non-hydrocarbon gases, such as noble gases. Twenty-five different hot springs, warm springs, cold springs, and/or rivers across the Utah region of the Colorado Plateau were sampled for microbial biomass. These different locations were associated with some concentration of dissolved or e
Repetitive sampling and control threshold improve 16S rRNA results from produced waters associated with hydraulically fractured shales
Sequencing microbial DNA from deep subsurface environments is complicated by a number of issues ranging from contamination to non-reproducible results. Many samples obtained from these environments - which are of great interest due to the potential to stimulate microbial methane generation - contain low biomass. Therefore, samples from these...

Compositional analysis of formation water geochemistry and microbiology of commercial and carbon dioxide-rich wells in the southwestern United States
Studies of naturally occurring subsurface carbon dioxide (CO2) accumulations can provide useful information for potential CO2 injection projects; however, the microbial communities and formation water geochemistry of most reservoirs are understudied. Formation water and microbial biomass were sampled at four CO2-rich reservoir sites: two within...

Assessment of undiscovered oil and gas resources in the Central North Slope of Alaska, 2020
Using a geology-based assessment methodology, the U.S. Geological Survey estimated undiscovered, technically recoverable mean resources of 3.6 billion barrels of oil and 8.9 trillion cubic feet of natural gas (associated and nonassociated) in conventional accumulations in Mississippian through Paleogene strata in the central North Slope...

Carbon dioxide mineralization feasibility in the United States
Geologic carbon dioxide (CO2) storage is one of many methods for stabilizing the increasing concentration of CO2 in the Earth’s atmosphere. The injection of CO2 in deep subsurface sedimentary reservoirs is the most commonly discussed method; however, the potential for CO2 leakage can create long-term stability concerns. This report discusses the...
Blondes, Madalyn S.; Merrill, Matthew D.; Anderson, Steven T.; DeVera, Christina A. Microbial community composition of a hydrocarbon reservoir 40 years after a CO2 enhanced oil recovery flood
Injecting CO2 into depleted oil reservoirs to extract additional crude oil is a common enhanced oil recovery (CO2-EOR) technique. However, little is known about how in situ microbial communities may be impacted by CO2 flooding, or if any permanent microbiological changes occur after flooding has ceased. Formation water was...

Geologic framework for the national assessment of carbon dioxide storage resources—Atlantic Coastal Plain and Eastern Mesozoic Rift Basins
This chapter presents information pertinent to the geologic carbon dioxide (CO2) sequestration potential within saline aquifers located in the Atlantic Coastal Plain and Eastern Mesozoic Rift Basins of the Eastern United States. The Atlantic Coastal Plain is underlain by a Jurassic to Quaternary succession of sedimentary strata that onlap westward...

Mantle and crustal gases of the Colorado Plateau: Geochemistry, sources, and migration pathways
The Colorado Plateau hosts several large accumulations of naturally occurring, non-hydrocarbon gases, including CO2, N2, and the noble gases, making it a good field location to study the fluxes of these gases within the crust and to the atmosphere. In this study, we present a compilation of 1252 published gas-composition ...

Atmospheric particulate matter in proximity to mountaintop coal mines: Sources and potential environmental and human health impacts
Mountaintop removal mining (MTM) is a widely used approach to surface coal mining in the US Appalachian region whereby large volumes of coal overburden are excavated using explosives, removed, and transferred to nearby drainages below MTM operations. To investigate the air quality impact of MTM, the geochemical characteristics of atmospheric...
