Impact of shale gas development on regional water quality
TLDR
Improved understanding of the fate and transport of contaminants of concern and increased long-term monitoring and data dissemination will help effectively manage water-quality risks associated with unconventional gas industry today and in the future.Abstract:
Unconventional natural gas resources offer an opportunity to access a relatively clean fossil fuel that could potentially lead to energy independence for some countries. Horizontal drilling and hydraulic fracturing make the extraction of tightly bound natural gas from shale formations economically feasible. These technologies are not free from environmental risks, however, especially those related to regional water quality, such as gas migration, contaminant transport through induced and natural fractures, wastewater discharge, and accidental spills. We review the current understanding of environmental issues associated with unconventional gas extraction. Improved understanding of the fate and transport of contaminants of concern and increased long-term monitoring and data dissemination will help manage these water-quality risks today and in the future.read more

Natural gas from shale formation – The evolution, evidences and challenges of shale gas revolution in United States
TL;DR: The history of US shale gas in this article is divided into three periods and based on the change of oil price (i.e., the period before the 1970s oil crisis, the period from 1970s to 2000, and the period since 2000), the US has moved from being one of the world's biggest importers of gas to being selfsufficient in less than a decade, with the shale gas production increasing 12fold (from 2000 to 2010).

Carbon and hydrogen isotope systematics of bacterial formation and oxidation of methane
TL;DR: In this paper, the major dissolved carbon species in diagenetic settings are represented by the two carbon redox endmembers CH4 and CO2, and they can be tracked with the aid of carbon ( 13 C / 12 C ) and hydrogen ( D/H≡ 2 H/ 1 H ) isotopes.

Methane contamination of drinking water accompanying gas-well drilling and hydraulic fracturing
TL;DR: It is concluded that greater stewardship, data, and—possibly—regulation are needed to ensure the sustainable future of shale-gas extraction and to improve public confidence in its use.

Water Management Challenges Associated with the Production of Shale Gas by Hydraulic Fracturing
TL;DR: Water management has emerged as a critical issue in the development of these inland gas reservoirs, where hydraulic fracturing is used to liberate the gas as discussed by the authors, where large volumes of water containing very high concentrations of total dissolved solids (TDS) return to the surface.
