There are 15 (of an original 27) municipal sewage treatment plants in Pennsylvania that still accept Marcellus Shale drilling wastewater. That is, until May 19 of this year. The plants are not fully licensed for treating drilling wastewater but were given an exception to new rules that went into effect, allowing them to continue the
Horizontal drilling and high-volume hydraulic fracturing (HVHF) are used in combination to extract natural gas, condensate, and oil from shale reservoirs in the United States at rates affecting the world economy (1 –4).In the shale gas-rich Marcellus Formation, such slick water HVHF began in 2004, leading to >8,000 Marcellus wells …

The Marcellus Shale lies under the Appalachian Basin, and spreads across New York, Pennsylvania, Ohio, West ia, Maryland, Tennessee, ia and Kentucky. The shale play is one of the largest in terms of geographic area, and the United States Geological Survey (USGS) estimates the formation's total area to be around 95,000 square miles, …
The geology and drilling trends within the Marcellus Shale suggest that areas in the southwest, north-central and northeastern regions of Pennsylvania may be especially productive. The most productive interval of the Marcellus Shale occurs at a depth of 5,000 to 8,500 feet below the ground surface, or roughly more than a mile. NATURAL GAS ...
Flowback & Brine in Pennsylvania: Someone may try to convince you that using 4-million gallons of water for fracing one gas well doesn't amount to a massive amount of water.Even if they are successful in making that argument, the next topic becomes flowback or brine. What do you do with the crap that comes back out of the ground? Early in the Marcellus …
Origin of brines, salts and carbonate from shales of the Marcellus Formation: Evidence from geochemical and Sr isotope study of sequentially extracted fluids - …
Brine water that flows back from gas wells in the Marcellus Shale region after hydraulic fracturing is many times more salty than seawater, with high contents of various elements, including radium and barium. The chemistry is consistent with brines formed during the Paleozoic era, a study by an undergraduate student and two professors in Penn State's …
The Marcellus Shale natural gas deposits are located at depths of 3,000 feet in Ohio dipping to more than 9,000 feet in depth eastward near the ia border, and the average depth of Marcellus Shale wells in West ia is 5,300 feet (Figure 2). The Marcellus Shale layer varies from between 50 to 100 feet
Abstract Flowback water is the solution that returns to the surface following completion of the hydraulic fracturing process during natural gas extraction. This study examines and analyzes the constituents that make up flowback waters collected from various drilling sites in Marcellus shale formation in the states of Pennsylvania, New …
Brine. Eight hundred-one (801) of the reported Marcellus wells produced brine, with volumes ranging from 2 to 24,165. For the moment, there is no choice but to assume that all of this is reported in the same unit, which will be assumed to be gallons.

(Marcellus Shale Energy and Environmental Laboratory) carbonate-rich sample is related to compaction of cores under stress due to matrix softening with substantial dissolution, and pore-filling ...
As a result, if oil or gas well brine were entering the waterways, TDS and Cl − levels would rise, along with other constituents of the brine. Prior to 2008, before the Marcellus Shale boom began, Pennsylvania's gas industry historically had drilled vertical wells into permeable sandstone reservoirs.

He also said the Marcellus was an unlikely source of the brine because it does not contain much water. "There is a question of time scale and what length of time matters," Engelder wrote in his ...
For example, groundwater contamination by stray natural gas and spillage of brine and other gas drilling-related fluids is known to occur. However, contamination of shallow potable aquifers by HVHF at depth has never been fully documented. ... We investigated a case where Marcellus Shale gas wells in Pennsylvania caused inundation of natural ...
Marcellus Shale gas development uses large volumes of fluid for fracturing operations (approximately 10,000 to 30,000 m 3), about 90% of which initially remains bound to the dry shale matrix (SRBC, 2010). ... Produced brine is extremely salty (>100,000 mg/L TDS), and may contain relatively high levels of metals, organic …
Radium is fairly soluble in water, and can be found in high concentrations (sometimes exceeding 10,000 pCi L-1) in Marcellus Shale brine water (Rowan et al. 2011; Warner et al. 2012). The EPA drinking water standard for Ra-226 is 5 pCi L-1, and there is evidence for transport from shale brines to shallow drinking water aquifers (Warner et al ...

The release, transport, and accumulation of Li in shale brines were numerically simulated through the basin–scale modeling, as combined with the experimental findings. The modeling results presented the potential of Marcellus Shale brines as a source of Li, depending on the dominant cation in the system. •.

subsurface in the region underlain by Marcellus Shale (Poth, 1962; Rose and Dresel, 1990; Dresel and Rose, 2010; Haluszczak et al., 2012; Warner et al., 2012). Given the ubiquity of deep brine, we assume that where water is present in the Marcellus Shale, even as capillary-bound water, it is brine. We propose a model in which the temporal
