Proppants used during hydraulic fracturing of oil and gas wells are manufactured to maximize petroleum yield by controlling the size, shape, density, and strength of the proppant material. The most common types of proppants are mined silica sand and manufactured ceramics, some of which are further modified with organic resin coatings to improve performance. Much of the work on the environmental and human health effects of proppant releases into the environment has focused on occupational silicosis, with little attention given to the potential effects from the organic coatings on these materials. This oversight is especially relevant in the context of dumping of unwanted proppant on the land surface, which has been...

USGS Science Data Catalog (SDC),
Oil and gas (OG) wastewaters are commonly disposed of by underground injection and previous research showed that activities at a disposal facility in West Virginia affected stream biogeochemistry and sediment microbial communities downstream from the facility. Microorganisms can control the fate and transport of organic and inorganic components of OG wastewater highlighting the need to characterize the effects of OG wastewater components on microbial activity. We conducted a series of aerobic microcosm experiments to assess the influence of high total dissolved solids (TDS) and hydraulic fracturing fluid additives (2,2-dibromo-3-nitrilopropionamide (DBNPA), a biocide, and ethylene glycol, an anti-scaling additive),...

The Marcellus Shale Energy and Environmental Laboratory (MSEEL) field site in Morgantown, WV was established by West Virginia University in order to increase understanding of factors that affect resource recovery and environmental impacts from unconventional oil and gas development. The site, which is located in the Morgantown Industrial Park (MIP) adjacent to the Monongahela River, includes one well pad which hosts four horizontal gas wells that target the Marcellus Shale approximately 7400 ft below ground level. As part of the MSEEL study, the MIP 5H well was drilled in 2015. Water samples were collected from the holding pond used to hydraulically fracture the MIP 5H well (API 47-061-01699), and a time series...

Data on Produced Water Quality and Quantities from Hydraulically Fractured Williston Basin Oil Wells
This dataset contains compositional data on 17 produced water samples from hydraulically fractured unconventional oil wells completed in the Middle Bakken and Three Forks Formations. The oil wells are located in five different wellfields across the Williston Basin. Specific gravity, conductivity, temperature, pH and oxidation-reduction potential for each sample was measured in the field. Ions (B, Li, Cl, Na, Br), biomarkers (Pristane /n-C17 and Phytane /n-C18), glycol ether compounds, major ions, as well as radium (Ra-228/Ra-226), boron (δ11B), oxygen (δ18O) and hydrogen (δ2H) isotopic ratios were analyzed in the lab. Well profiles are provided to increase understanding of the produced waters compositions in the...
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 different Utica wells that had been in production between 1-5 years, spanning the oil and gas windows of SE Ohio. The samples were filtered for biomass, extracted, amplified, and 16S rRNA gene sequencing was performed on the Illumina MiSeq platform.
