Abstract Until now, up‐to‐date, comprehensive, spatial, national‐scale data on hydraulic fracturing water volumes have been lacking. Water used (injected) to hydraulically fracture over 263,859 oil and gas wells drilled between 2000 2014 were compiled create the first U.S. map of use. Although median annual 15,275 m 3 19,425 per well was individual horizontal wells, respectively, in 2014, about 42% actually either vertical or directional, which required less than 2600 well. The highest...
There is increasing interest in beneficial uses of large volumes wastewater co-produced with oil and gas extraction (produced water, PW) because water scarcity, potential subsurface disposal limitations, regional linkages to induced seismicity. Here we quantified PW relative demand different sectors quality treatment reuse options for the major U.S. shale plays. from these plays totaled ~600 billion liters (BL, 160 gallons, Bgal) 2017. One year equal ~60% one day freshwater use For plays,...
Radium activity data for waters co-produced with oil and gas in New York Pennsylvania have been compiled from publicly available sources are presented together new six wells, including one time series. When available, total dissolved solids (TDS), gross alpha beta particle activities also were compiled. Data the 1990s earlier sandstone limestone oil/gas reservoirs of Cambrian-Mississippian age; however, recent almost exclusively Middle Devonian Marcellus Shale. The Shale represents a vast...
The number of Marcellus Shale gas wells drilled in the Appalachian basin has increased rapidly over past decade, leading to interest highly saline water produced with natural which must be recycled, treated, or injected into deep disposal wells. New geochemical and isotopic analyses for 3 time-series 13 grab samples from southwest north central Pennsylvania (PA) are used address origin solutes long term (>12 months). question whether originated within Shale, it may have been drawn adjacent...
Wastewaters from oil and gas development pose largely unknown risks to environmental resources. In January 2015, 11.4ML (million liters) of wastewater (300g/L TDS) production in the Williston Basin was reported have leaked a pipeline, spilling into Blacktail Creek, North Dakota. Geochemical biological samples were collected February June 2015 identify geochemical signatures spilled wastewaters as well responses along 44-km river reach. water had elevated chloride (1030mg/L) bromide (7.8mg/L)...
Despite being one of the most important oil producing provinces in United States, information on basinal hydrogeology and fluid flow Permian Basin Texas New Mexico is lacking. The source geochemistry brines from basin were investigated (Ordovician- to Guadalupian-age reservoirs) by combining previously published data conventional reservoirs with geochemical results for 39 new produced water samples, a focus those shales. Salinity Ca–Cl-type generally increases depth reaching maximum Devonian...
The development of unconventional oil and gas (UOG) resources has rapidly increased in recent years; however, the environmental impacts risks are poorly understood. A single well can generate millions liters wastewater, representing a mixture formation brine injected hydraulic fracturing fluids. One most common methods for wastewater disposal is underground injection; we assessing potential this method through an intensive, interdisciplinary study at injection facility West Virginia. In June...
This study presents >5 cumulative years of tropospheric mercury (Hg) speciation measurements, over the period 2003–2009, for eight sites in central and eastern United States one site coastal Puerto Rico. The purpose this research was to identify local regional processes that impact Hg deposition (wet + dry) across a large swath North America. Sites sampled were selected represent both wide range exposure environmental conditions. Seasonal mean concentrations elemental (1.27 ± 0.31 2.94...
