Development of unconventional, onshore natural gas resources in deep shales is rapidly expanding to meet global energy needs. 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. Following hydraulic fracturing, large volumes of water containing very high concentrations of total dissolved solids (TDS) return to the surface. The TDS concentration in this wastewater, also known as “flowback,” can reach 5 times that of sea water. Wastewaters that contain high TDS levels are challenging and costly to treat. Economical production of shale gas resources will require creative management of flowback to ensure protection of groundwater and surface water resources. Currently, deep-well injection is the primary means of management. However, in many areas where shale gas production will be abundant, deep-well injection sites are not available. With global concerns over the quality and quantity of fresh water, novel water management strategies and treatment technologies that will enable environmentally sustainable and economically feasible natural gas extraction will be critical for the development of this vast energy source.read more

Experimental study on the mechanism of coupled dynamic–static fracturing on damage evolution and crack propagation in tight shale
TL;DR: In this article , a coupled dynamic-static hydraulic fracturing technique and its mechanism for the damage evolution and crack propagation in tight shale reservoirs were investigated, and the results showed that the cumulative damage under increasing pulsation amplitude and UPL showed a trend of first increasing and then decreasing, implying that there are optimal pulsation parameters for the fracturing process.

Comparative life-cycle air emissions of coal, domestic natural gas, LNG, and SNG for electricity generation.
TL;DR: In this paper, the authors compare greenhouse gas (GHG), SOx, and NOx life-cycle emissions of electricity generated with NG/LNG/SNG and coal and show that with the current fleet of power plants, a mix of domestic NG, LNG, and SNG would have lower GHG emissions than coal.
