water/brine recovered from the shale after frac fluid injection and during gas production.

aquifers suggests possible migration of Marcellus brine through naturally occurring pathways. The occurrences of saline water do not correlate with the location of shale-gas wells and are consistent with reported data before rapid shale-gas development in the re-gion; however, the presence of these fluids suggests conductive

Nov 16, 2008· The challenge ahead for Marcellus Shale gas developers is to identify techniques to deliver the water required for drilling and completion and to develop methods for the disposal of brines represented by flowback and produced water that comply with applicable environmental regulations.

Dec 26, 2012· Capillary tension and imbibition sequester frack fluid in Marcellus gas shale. In a recent issue of PNAS, Warner et al. ( 1) interpreted local ground water chemistry in the Appalachian Basin as a signal for cross-formational pathways where natural migration of brine from the …

Sep 23, 2009· Currently, it appears likely that disposal via Class II brine water disposal wells will be an important option for managing water produced from Marcellus Shale wells over the long-term. This paper is structured toward brine disposal issues in Appalachia and …

Jul 09, 2012· These pathways allowed gases and Marcellus brine to migrate up into shallow groundwater aquifers from deeper underground shale gas deposits. "This could mean that some drinking water supplies in northeastern Pennsylvania are at increased risk for contamination, particularly from fugitive gases that leak from shale gas well casings," Vengosh said.

The U. Devonian sandstone brines (Greene Co.) have δ7Li values in a narrow range (+13.7‰ to +15.4‰) and are distinct from Marcellus Shale produced waters from the same region (+7.63‰ to +10.5‰). This suggests minimal present migration of brine from Marcellus brines and deeper units upward into the overlying U. Devonian sandstones.

Along with the gas that's produced out of these wells, you get brine; that is, saltwater. Keep in mind that the Marcellus was an ancient sea deposit, so there are salts trapped in the shale itself, along with deeper fluids that were injected up into the shale from a great depth, which also contained a lot of salt.

Dec 03, 2009· Meanwhile, the Marcellus wastewater has to go somewhere. In the past, DEC has allowed brine to be spread on roads to help melt snow and keep down the dust. But public comments at DEC hearings and the recent Marcellus Shale summit held in Owego earlier this week indicate that people aren't comfortable with the idea of "hot salt" on their roads.
