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. 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) to better understand produced water impacts at the surface or in shallow subsurface aquifers, and (c) to help inform treatment and reuse options.

Utica shale play oil and gas brines: Geochemistry and factors influencing wastewater management
The Utica and Marcellus Shale Plays in the Appalachian Basin are the fourth and first largest natural gas producing plays in the United States, respectively. Hydrocarbon production generates large volumes of brine (“produced water”) that must be disposed of, treated, or reused. Though Marcellus brines have been studied extensively, there are few studies from the Utica Shale Play. This study presen

Geophysical mapping of produced water in near-surface environments
This task within the Oil and Gas Waters Project focuses on the development of oil and gas resources results in substantial volumes of produced water. Particularly when produced from deep geologic formations, these waters can exhibit elevated salinity in comparison to shallow groundwater at the same location. Knowing the spatial and temporal occurrence of high salinity produced water in groundwater...Quantities of water associated with oil and gas development
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...Hydraulic Fracturing
Hydraulic fracturing, commonly known as fracking, is the process of injecting water, sand, and/or chemicals into a well to break up underground bedrock to free up oil or gas reserves. The USGS monitors the environmental impact of this practice across the country, from potential earthquakes to degraded groundwater quality.Oil and Gas Waters Project
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... - Data
Absorbance and Fluorescence Excitation-Emission Matrix Data for Produced Waters from Oil and Gas Producing Basins in the United States
Waters co-produced during petroleum extraction are normally considered wastes but are also possible resources, especially in water-stressed regions. Produced waters can be chemically complex. High salinity, naturally occurring radioactive materials, and organic substances derived from the producing formation can complicate treatment processes. Rapid screening methods to characterize produced waterLow biomass microbiology samples collected from a hydraulically fractured well producing from the Niobrara Shale in Colorado
Low biomass waters provide a unique challenge in the field of microbial ecology. It is difficult to determine, when biomass concentrations are extremely low, whether or not the sequencing data received are of good quality and representative of the waters sampled. Fifty-nine samples including 8 blanks were collected from a low biomass hydraulically fractured well producing from the Niobrara Shale i - Publications

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 Bravo Dome, a commercial CO2 field in New Mexico; oneAuthorsJenna L. Shelton, Robert S.

The Piper diagram has been a staple for the analysis of water chemistry data since its introduction in 1944. It was conceived to be a method for water classification, determination of potential water mixing between end-members, and to aid in the identification of chemical reactions controlling a sample set. This study uses the information gleaned over the years since the release of the Piper diagrAuthorsJenna L. Shelton, Mark A. Engle, Antonella Buccianti, Madalyn S.

Despite being one of the most important oil producing provinces in the United States, information on basinal hydrogeology and fluid flow in the Permian Basin of Texas and New Mexico is lacking.

In the geosciences, isotopic ratios and trace element concentrations are often used along with major element concentrations to help determine sources of and processes affecting geochemical variation. Compositional Data Analysis (CoDA) is a set of tools, generally attuned to major element data, concerned with the proper statistical treatment and removal of spurious correlations from compositional dAuthorsMadalyn S.

Natural gas produced from coal beds (coal-bed methane, CBM) accounts for about 7.5 percent of the total natural gas production in the United States. Along with this gas, water is also brought to the surface. The amount of water produced from most CBM wells is relatively high compared to conventional natural gas wells because coal beds contain many fractures and pores that can contain and transmitAuthors - Web Tools
