“…1,2 However, hydraulic fracturing has a few drawbacks, including potential surface water shortage due to high-volume hydraulic fracturing, risks of ground and surface water contamination caused by additives in the fracturing uid, the accumulation of toxic and radioactive elements in soil, risk of induced seismicity by large-scale wastewater disposal, etc. [3][4][5] Therefore, seeking an alternative fracturing uid has received considerable attention from researchers. Meanwhile, carbon emission has been another hot topic due to the fact of global warming.…”

“…Many recent publications, such as Guo et al [34], Gao et al [35], Chebeir et al [36], Chen et al [37], Drouven and Grossmann [38], He et al [39], and Wang et al [40] have discussed different optimal modeling approaches for shale gas water management systems with socio-economic and environmental concerns. All of the above studies are confined to only uncertain modeling approaches, and have not discussed uncertainty among parameters' values; however, Zhang et al [22] incorporated vagueness among parameters and represented it by fuzzy and stochastic quantification methodology.…”

Shale gas energy is the most prominent and dominating source of power across the globe. The processes for the extraction of shale gas from shale rocks are very complex. In this study, a multiobjective optimization framework is presented for an overall water management system that includes the allocation of freshwater for hydraulic fracturing and optimal management of the resulting wastewater with different techniques. The generated wastewater from the shale fracking process contains highly toxic chemicals. The optimal control of a massive amount of contaminated water is quite a challenging task. Therefore, an on-site treatment plant, underground disposal facility, and treatment plant with expansion capacity were designed to overcome environmental issues. A multiobjective trade-off between socio-economic and environmental concerns was established under a set of conflicting constraints. A solution method—the neutrosophic goal programming approach—is suggested, inspired by independent, neutral/indeterminacy thoughts of the decision-maker(s). A theoretical computational study is presented to show the validity and applicability of the proposed multiobjective shale gas water management optimization model and solution procedure. The obtained results and conclusions, along with the significant contributions, are discussed in the context of shale gas supply chain planning policies over different time horizons.

“…For example, most previous studies that analyze the costs associated with unconventional fuel production do not address the costs (real or hidden) of accounting for the water availability required to perform fracking operations (e.g., [10], [11], [12]). Although some studies have related water-stressed regions with fracking activities [6], [13], [14], [15], only a few studies [16], [17], [18], attempted to quantify the potential impact of water used for fracking on the local and regional water resources. A recent national-scale assessment on water use for hydraulic fracturing in the US [20] calls for further studies that examine regional-scale energy and water sustainability challenges.…”

Background: Unconventional oil and gas reservoirs, frequently referred to as shale plays , have been gaining more attention in recent years. Hydraulic fracturing is performed to extract fossil fuels from unconventional reservoirs. Besides possible environmental implications, a better understanding of the potential stress that fracking may cause to water resources at the local or regional scale is still needed. The goal of this study is to assess the impact of current and projected future water demands for fracking on water resources in two main shale plays in Louisiana, USA. Methods: The analysis is performed in Louisiana’s two main shale plays, the Haynesville Shale and the Tuscaloosa Marine Shale, using the Water Supply Stress Index (WaSSI) framework. WaSSI is used to evaluate the stress at a fine watershed scale (HUC12) for annual-average conditions. The study analyzes different scenarios of historical and two future projected fracking conditions that simulate different extraction rates. In each fracking scenario, stresses on both surface and groundwater are evaluated separately. The study is based on a multitude of water supply and withdrawals datasets assembled and disaggregated to the watershed scale. Results: Under existing conditions, the impact of fracking water demands on surface water resources is within the low stress category in most watersheds in both shale plays. This impact remains low under more aggressive future fracking scenarios. In contrast, groundwater resources appear to be highly vulnerable under both the historical and projected fracking scenarios, especially in the Haynesville Shale where 20 out of the 94 watersheds become medium or highly stressed. If groundwater resources remained as a main source for fracking water, the number of stressed watersheds increased to 39 and 86 under the two projected future fracking scenarios. The least exploited Tuscaloosa Marine Shale remains mostly under low stress, except in the most aggressive future fracking scenario. Conclusions: Surface water resources in Louisiana’s shale plays seem abundant enough for fracking activities to rely on this source instead of groundwater whenever possible. Groundwater resources in Louisiana are clearly vulnerable to fracking activities, especially for the Haynesville shale play, under current and future projected fracking conditions.
