A review of biophysical and socio-economic effects of unconventional oil and gas extraction – Implications for South Africa
Surina Esterhuyse, Marinda Avenant, Nola Redelinghuys, Andrzej Kijko, Jan Glazewski, Lisa Plit, Marthie Kemp, Ansie Smit, A. Tascha Vos, Richard Williamson (2016). Journal of Environmental Management, . 10.1016/j.jenvman.2016.09.065
Abstract:
The impacts associated with unconventional oil and gas (UOG) extraction will be cumulative in nature and will most likely occur on a regional scale, highlighting the importance of using strategic decision-making and management tools. Managing possible impacts responsibly is extremely important in a water scarce country such as South Africa, versus countries where more water may be available for UOG extraction activities. This review article explains the possible biophysical and socio-economic impacts associated with UOG extraction within the South African context and how these complex impacts interlink. Relevant policy and governance frameworks to manage these impacts are also highlighted.

The impacts of fracking on the environment: A total environmental study paradigm
Qingmin Meng (2016). Science of The Total Environment, . 10.1016/j.scitotenv.2016.12.045
Abstract:
Fracking has become a hot topic in the media and public discourse not only because of its economic benefit but also its environmental impacts. Recently, scientists have investigated the environmental impacts of fracking, and most studies focus on its air and ground water pollution. A systematic research structure and an overall evaluation of fracking's impacts on the environment are needed, because fracking does not only influence ground water but most environmental elements including but not limited to air, water, soil, rock, vegetation, wildlife, human, and many other ecosystem components. From the standpoint of the total environment, this communication assesses the overall impacts of fracking on the environment and then designs a total environmental study paradigm that effectively examines the complicated relationship among the total environment. Fracking dramatically changes the anthroposphere, which in turn significantly impacts the atmosphere, hydrosphere, lithosphere, and biosphere through the significant input or output of water, air, liquid or solid waste disposals, and the complex chemical components in fracking fluids. The proposed total environment study paradigm of fracking can be applied to other significant human activities that have dramatic impacts on the environment, such as mountain top coal mining or oil sands for environmental studies.

A systematic quality assessment of Environmental Impact Statements in the oil and gas industry

A systematic quality assessment of Environmental Impact Statements in the oil and gas industry
B. Anifowose, D. M. Lawler, D. van der Horst, L. Chapman (2016). Science of The Total Environment, 570-585. 10.1016/j.scitotenv.2016.07.083
Abstract:
The global economy relies heavily on oil and gas resources. However, hydrocarbon exploitation projects can cause significant impacts on the environment. But despite the production of numerous Environmental Impact Statements (EISs) to identify/mitigate such impacts, no study has specifically assessed the quality of EISs for both onshore and offshore oil and gas projects, with tested hypotheses. To address this research gap, our paper, for the first time, develops a modified Lee and Colley evaluation model to assess the quality of 19 sampled oil and gas project EISs produced from 1998 to 2008 in Nigeria. Our findings show that Project Description and Communication of Results are the main areas of strength. However, Environmental Impact Prediction, and Project Decommissioning, were among the key areas requiring attention. A key finding, though, is that Mann-Whitney tests suggest that there is no evidence that the quality of EISs for the latter period (2004–2008) is higher than that of the earlier period (1998–2004). We suggest that periodic systematic review of the quality of submitted/approved EISs (c. every 3–5 years) should be established to monitor trends in EIS quality and identify strong and weak areas. This would help to drive continual improvement in both the EIA processes and the resultant EISs of technical engineering projects. Such reviews have the potential to illuminate some of the underlying problems of, and solutions to, oil and gas exploration, production and transportation, and their related environmental impacts. This suggested change would also be useful internationally, including for the burgeoning exploration and production of unconventional hydrocarbon resources.

Evaluation of Environmental Hazard During Shale Gas Exploration Process in Poland in the Years 2012-2014
Monika Konieczyńska, Jan Macuda, Stanisława Nagy, Jakub Siemek (2016). Ecological Chemistry and Engineering S, 571–581. 10.1515/eces-2016-0040
Abstract:
This paper is a summary of results of environmental analysis conducted by PGI-NRI, AGH-UST within the monitoring of natural gas prospecting in unconventional deposits. All elements of natural environment were analyzed and on this basis the qualitative and quantitative impact of drilling and hydraulic fracturing of shales could be assessed. Special attention was drawn to the analysis of the physicochemical condition of post-reaction fluids, soil gas in the well pad area and drilling fluids. The results of analysis reveal that prospecting works do not create a significant environmental hazard. Some indices connected, e.g. with the noise climate lightly exceeded permissible values. Nonetheless, if extensive prospecting and production of shale gas are involved, the environmental studies need to be broadened to supplement this report.

Hydraulic fracturing: Assessing self-reported familiarity and the contributions of selected sources to self-reported knowledge
Gene L. Theodori and Colter Ellis (2016). The Extractive Industries and Society, . 10.1016/j.exis.2016.11.003
Abstract:
Data collected from a random sample of individuals in two counties in the Eagle Ford Shale region of South Texas to examine (a) respondents’ self-reported familiarity with the process of hydraulic fracturing and (b) the associations between the contributions of information sources to self-reported knowledge about hydraulic fracturing and self-reported levels of familiarity with the process of hydraulic fracturing. The results of this study revealed that survey respondents in the Eagle Ford Shale region of Texas are more familiar with the process of hydraulic fracturing than has been reported in other studies. Moreover, the findings indicated that self-reported levels of familiarity with the process of hydraulic fracturing were positively associated with certain sources of information. Among those sources that reached statistical significance, the strongest contributor to respondents’ self-reported familiarity with hydraulic fracturing was information from the oil/natural gas industry.

A risk assessment tool applied to the study of shale gas resources
Miguel Veiguela, Antonio Hurtado, Sonsoles Eguilior, Fernando Recreo, Nieves Roqueñi, Jorge Loredo (2016). Science of The Total Environment, . 10.1016/j.scitotenv.2016.07.021
Abstract:
The implementation of a risk assessment tool with the capacity to evaluate the risks for health, safety and the environment (HSE) from extraction of non-conventional fossil fuel resources by the hydraulic fracturing (fracking) technique can be a useful tool to boost development and progress of the technology and winning public trust and acceptance of this. At the early project stages, the lack of data related the selection of non-conventional gas deposits makes it difficult the use of existing approaches to risk assessment of fluids injected into geologic formations. The qualitative risk assessment tool developed in this work is based on the approach that shale gas exploitation risk is dependent on both the geologic site and the technological aspects. It follows from the Oldenburg's ‘Screening and Ranking Framework (SRF)’ developed to evaluate potential geologic carbon dioxide (CO2) storage sites. These two global characteristics: (1) characteristics centered on the natural aspects of the site and (2) characteristics centered on the technological aspects of the Project, have been evaluated through user input of Property values, which define Attributes, which define the Characteristics. In order to carry out an individual evaluation of each of the characteristics and the elements of the model, the tool has been implemented in a spreadsheet. The proposed model has been applied to a site with potential for the exploitation of shale gas in Asturias (northwestern Spain) with tree different technological options to test the approach.

Reducing the environmental impact of hydraulic fracturing through design optimisation of positive displacement pumps
Aleksandar Josifovic, Jennifer J. Roberts, Jonathan Corney, Bruce Davies, Zoe K. Shipton (2016). Energy, 1216-1233. 10.1016/j.energy.2016.09.016
Abstract:
The current approach to hydraulic fracturing requires large amounts of industrial hardware to be transported, installed and operated in temporary locations. A significant proportion of this equipment is comprised of the fleet of pumps required to provide the high pressures and flows necessary for well stimulation. Studies have shown that over 90% of the emissions of CO2 and other pollutants that occur during a hydraulic fracturing operation are associated with these pumps. Pollution and transport concerns are of paramount importance for the emerging hydraulic fracturing industry in Europe, and so it is timely to consider these factors when assessing the design of high pressure pumps for the European resources. This paper gives an overview of the industrial plant required to carry out a hydraulic fracturing operation. This is followed by an analysis of the pump's design space that could result in improved pump efficiency. We find that reducing the plunger diameter and running the pump at higher speeds can increase the overall pump efficiency by up to 4.6%. Such changes to the pump's parameters would results in several environmental benefits beyond the obvious economic gains of lower fuel consumption. The paper concludes with a case study that quantifies these benefits.

Shale gas debate in Europe: Pro-and-con dialectics and argumentative polylogues
Marcin Lewiński (2016). Discourse & Communication, 1750481316674773. 10.1177/1750481316674773
Abstract:
In this article I scrutinise a crucial tension in understanding the debate over shale gas production in Europe. On the one hand, analyses predominantly grasp the debate in terms of pro-and-con dialectics, as if the pro-shale gas camp faced the anti-shale gas camp in a dyadic clash of opposing voices. On the other hand, it is commonly recognised that this debate is driven by multi-party and multi-position argumentative dynamics. In this broader context, I focus on one pivotal contribution to the debate – Gazprom’s press release from October 2013 outlining Russia’s energy giant’s strategy of dealing with unconventional gas production. I employ concepts and methods of argumentative discourse analysis to contend that an arguer to a multi-party debate – argumentative polylogue – faces a number of constraints and opportunities that cannot be adequately grasped in terms of dyadic pro-and-con dialectics. The analysis reveals how Gazprom needs to simultaneously design its discourse to address a number of other parties who might also disagree among themselves: from Greenpeace to European Union governments to shale gas companies. I show why and how a stakeholder analysis used in organisational communication might lead to a better understanding of this form of multi-party public argumentation.

Fracking: A creature of government?
Gage Counts and Walter E. Block (2016). Energy & Environment, 0958305X16677184. 10.1177/0958305X16677184
Abstract:
Like most other things, fracking has its good and bad points. In the former regard, it is a technological breakthrough that can increase the supplies of energy of the entire economy. In the latter, it has been linked with an increased incidence of earthquakes and water pollution, surely negatives. As well, there is some evidence fracking would not exist, at least not to the present extent, were it not for government subsidies, which, we argue, misallocate resources.

The Power of Policy Regimes: Explaining Shale Gas Policy Divergence in Bulgaria and Poland
Andreas Goldthau and Michael LaBelle (2016). Review of Policy Research, 603-622. 10.1111/ropr.12204
Abstract:
Shale gas policies vary significantly across Europe, notably in Russia-dependent Central Eastern Europe. Most strikingly, Bulgaria banned shale gas, whereas Poland remains firmly committed to fostering it despite its drawbacks. This article uses a policy regime approach to explain the shale gas puzzle. Drawing on a large set of interviews, the piece investigates regime strength as the causal factor that explains the adoption of specific shale gas laws (Poland) or a fracking ban (Bulgaria). It finds that the Polish shale gas policy regime was strong, based on a powerful political narrative and characterized by an institutional process ensuring the buy-in of actors from relevant policy levels and subsystems. In Bulgaria the policy regime was weak, failed to co–opt key stakeholders, and was institutionally ill-designed. The findings show how different degrees of policy regime strength translate into diverging policy trajectories in two countries that otherwise operate in similar environments.

Shale gas and fracking: exploration for unconventional hydrocarbons
Iain C. Scotchman (2016). Proceedings of the Geologists' Association, 535-551. 10.1016/j.pgeola.2016.09.001
Abstract:
Geological perspective and discussion of shale reservoired hydrocarbons (shale gas and shale oil) and the emotive process used to produce them, hydraulic fracturing or fracking in colloquial parlance, is timely, in view of the current debate on the potential for exploitation of shales in the UK. Fracking is a long-standing oil industry process which has recently allowed unconventional hydrocarbons to dominate much of the world oil industry. This is particularly so in the USA where their development has dramatically overturned the decline in domestic production, with the current attainment of near self-sufficiency in both oil and gas production. Exploration for, and production of, shale-reservoired hydrocarbons requires a very different approach and mind-set from that required for conventional oil and gas resources, as well as raising widespread concerns around environmental aspects of fracking. The aim of this paper is to discuss the geology of shale resources and the techniques developed for their exploration and exploitation and place the environmental issues in their geological, not socio-economic context.

Energy Technology, Politics, and Interpretative Frames: Shale Gas Fracking in Eastern Europe

Energy Technology, Politics, and Interpretative Frames: Shale Gas Fracking in Eastern Europe
Andreas Goldthau and Benjamin K. Sovacool (2016). Global Environmental Politics, 50-69. 10.1162/GLEP_a_00375
Abstract:
This article explores competing interpretive frames regarding shale gas in Bulgaria, Poland, and Romania. These countries face the choice of embracing shale gas as a potential revolutionizing domestic source of energy, against the backdrop of Russia serving as the dominant gas supplier. This makes them interesting cases for studying how policy narratives and discourses coalesce around a novel technology. The findings, which are based on sixty-six semistructured research interviews, point to differing and indeed competing frames, ranging from national security, environmental boons to economic sellout and authoritarianism, with different sets of institutions sharing those frames. This suggests that enhancing energy security by way of deploying novel energy technologies such as shale gas fracking is not simply a function of resource endowments and technological progress. Instead, it is the result of complex dynamics unfolding among social stakeholders and the related discursive processes, which eventually will determine whether—or not—shale gas will go global.

Advocacy Coalition Resources and Strategies in Colorado Hydraulic Fracturing Politics
Jonathan J. Pierce (2016). Society & Natural Resources, 1154-1168. 10.1080/08941920.2015.1131876
Abstract:
This article examines how members of competing coalitions seek to influence public policy. Past research examined coalitions and policy change, but offered limited understanding about the relationships between coalitions’ resources, strategies, and policy change. The case study focuses on the establishment of various regulations related to hydraulic fracturing in Colorado. Data were collected using interviews (n = 14) and a survey (n = 137) of policy actors asking about their beliefs, resources, and strategies in April 2013. This study found that members of the coalition proposing stricter regulations were successful. This winning coalition more frequently engaged in a wider range of strategies and had greater public support compared to their opponents. The study also found that among the winning coalition members, leadership and information technology resources were associated with the majority of their strategies, but financial resources did not have a significant relationship with any strategy.

Delineating property rights in unconventional hydrocarbon resources: Concepts from the United States and Germany
Dirk Hanschel and Terence Centner (2016). Energy Research & Social Science, 149-157. 10.1016/j.erss.2016.08.004
Abstract:
The use of hydraulic fracturing (fracking) and horizontal drilling technologies for recovering unconventional hydrocarbons (oil and gas) has created issues concerning the rights of property owners, energy companies, and others involved with the development and distribution of these resources. Constitutional provisions, legislative statutes, and jurisprudence on liability in the United States and Germany affect rights to oil and gas resources and the profitability of developing these resources. Legal rules for trespass, the rule of capture, pooling, unitization, and municipal fracturing bans circumscribe property rights associated with shale gas development in the United States. Germany, until setting up a specific, long-term legal regime on hydraulic fracturing, will rely on existing mining, water, and environmental legislation (as most recently modified). The evaluation of the law and jurisprudence governing unconventional hydrocarbon development in the U.S. and Germany discloses perceptions and expectations that contribute to widespread extraction in the U.S. while Germany contemplates the safety of allowing hydraulic fracturing.

Abstract:
Many rural communities are facing complicated risks resulting from unconventional oil and gas development and hydraulic fracturing. This study focuses on residents’ experiences of risk and the factors limiting local leader’s efforts to protect residents. Data for this research were obtained through interviews with community leaders, industry officials, and focus groups with private citizens. Data collection occurred in four counties in the Eagle Ford Shale region of South Texas. Study participants shared examples of how their lives were impacted by increased truck traffic, food and housing insecurity, flaring of hydrogen sulfide (H2S) gas, and concerns about water contamination. Community leaders confront a tension between supporting economic growth and development associated with energy development, and managing these negative social and environmental outcomes. We identify three significant factors that weaken the power and limit the ability of local governments to effectively advocate for their communities. First, rural communities lack the staffing, expertise, and financial resources to properly cope with development. Second, the rural geography makes it difficult for local governments to work collaboratively across political borders. Third, the dominant conservative political values make it difficult for local leaders to advocate for increases in regional, state, or federal regulation.
Many rural communities are facing complicated risks resulting from unconventional oil and gas development and hydraulic fracturing.

Observations on risks, the social sciences, and unconventional hydrocarbons
Terence J. Centner (2016). Energy Research & Social Science, . 10.1016/j.erss.2016.08.007
Abstract:
The activities employed in the development of unconventional hydrocarbon resources have been accompanied with health and environmental damages. To address the risks and damages from these activities, social scientists are probing probabilities of harm, estimating damages, and evaluating the ability of governmental regulators to arrest conduct causing damages. This lead article for a special issue on “Risks, the Social Sciences, and Unconventional Hydrocarbons” summarizes twenty papers to offer insights for developing policies to address future unconventional hydrocarbon development. Although economic, cultural, and political distinctions mean that people in different countries have diverse expectations on how their government should regulate energy development, the experiences reported by the papers of this special issue suggest that appropriate technology and governmental oversight can minimize adverse effects. Future research on the application and incorporation of ideas and knowledge into decisions and activities present challenges that call for innovative social science research to assist policy makers in meeting the challenges presented by the world's need for energy resources.

The evolution of shale gas development and energy security in Poland: Presenting a hierarchical choice of priorities
Wiktor Adamus and Wojciech J. Florkowskib (2016). Energy Research & Social Science, . 10.1016/j.erss.2016.08.010
Abstract:
This paper uses the Analytic Hierarchy Process (AHP) to select the alternative consistent with the goal of achieving energy security in Poland. The study considers three possible alternatives: the extraction of shale gas from domestic sources (A), diversification of gas supply (B), and maintaining the status quo (C). Data for comparisons were obtained from interviews with energy sector experts after rejecting responses that did not meet consistency criteria. The alternative, which satisfies the largest number of the models' criteria and subcriteria is the alternative supporting shale gas mining (model A), while the second preferred alternative is the diversification of gas supply sources (model B). The least favorable is alternative C, maintaining the status quo. The study is the first to assess the energy security alternatives in Poland by obtaining a synthetic score reflecting multiple qualitative factors.

Statistical analysis of compliance violations for natural gas wells in Pennsylvania
Noura Abualfaraj, Mira S. Olson, Patrick L. Gurian, Anneclaire De Roos, Carol Ann Gross-Davis (2016). Energy Policy, 421-428. 10.1016/j.enpol.2016.07.051
Abstract:
Regulatory inspection and violation reports provide insight into the impact of natural gas extraction on the surrounding environment, human health, and public safety. Inspection reports for natural gas wells in Pennsylvania were collected from the Pennsylvania DEP Compliance Report from 2000 to 2014. Analysis of 215,444 inspection records for 70,043 conventional and unconventional wells was conducted in order to compare the odds of violations occurring under different circumstances. Logistic regression models were used to estimate the probability of violations occurring for both conventional and unconventional wells. When inspected, conventional wells had 40% higher odds of having a violation. However, unconventional wells had higher odds for environmental violations related to waste discharge as well as cementing and casing failures. Large operators had 40% lower odds of having any violation than smaller operators. While larger operators had fewer violations, a few of the largest companies had rates of violation much higher than the average for all operators, with some reaching violation rates as high as 1 in 4 active wells. A well also has a higher chance of being in violation if it is in the first year (85%) or second year (109%) since its spud date.

Abstract:
A growing area of research has addressed public perception of unconventional oil and natural gas development via hydraulic fracturing (“fracking”). We extend this research by examining how geographic proximity to such extraction interacts with political ideology to influence issue support. Regression analysis of data from a fall 2013 national telephone survey of United States residents reveals that as respondents’ geographic distance from areas experiencing significant development increases, political ideology becomes more strongly associated with issue support, with the liberal-partisan divide widening. Our findings support construal level theory's central premise: that people use more abstract considerations (like political ideology) the more geographically removed they are from an issue. We discuss implications for studying public opinion of energy development as well as for risk communication.

Population Size, Growth, and Environmental Justice Near Oil and Gas Wells in Colorado
Lisa M. McKenzie, William B. Allshouse, Troy Burke, Benjamin D. Blair, John L. Adgate (2016). Environmental Science & Technology, 11471-11480. 10.1021/acs.est.6b04391
Abstract:
We evaluated population size and factors influencing environmental justice near oil and gas (O&G) wells. We mapped nearest O&G well to residential properties to evaluate population size, temporal relationships between housing and O&G development, and 2012 housing market value distributions in three major Colorado O&G basins. We reviewed land use, building, real estate, and state O&G regulations to evaluate distributive and participatory justice. We found that by 2012 at least 378,000 Coloradans lived within 1-mile of an active O&G well, and this population was growing at a faster rate than the overall population. In the Denver Julesburg and San Juan basins, which experienced substantial O&G development prior to 2000, we observed a larger proportion of lower value homes within 500 feet of an O&G well and that most O&G wells predated houses. In the Piceance Basin, which had not experienced substantial prior O&G development, we observed a larger proportion of high value homes within 500 feet of an O&G well and that most houses predated O&G wells. We observed economic, rural, participatory, and/or distributive injustices that could contribute to health risk vulnerabilities in populations near O&G wells. We encourage policy makers to consider measures to reduce these injustices.

Sara Wylie, Kim Schultz, Deborah Thomas, Chris Kassotis, Susan Nagel (2016). New solutions: a journal of environmental and occupational health policy: NS, . 10.1177/1048291116666037
Abstract:
This article describes Dr Theo Colborn's legacy of inspiring complementary and synergistic environmental health research and advocacy. Colborn, a founder of endocrine disruption research, also stimulated study of hydraulic fracturing (fracking). In 2014, the United States led the world in oil and gas production, with fifteen million Americans living within one mile of an oil or gas well. Colborn pioneered efforts to understand and control the impacts of this sea change in energy production. In 2005, her research organization The Endocrine Disruption Exchange (TEDX) developed a database of chemicals used in natural gas extraction and their health effects. This database stimulated novel scientific and social scientific research and informed advocacy by (1) connecting communities' diverse health impacts to chemicals used in natural gas development, (2) inspiring social science research on open-source software and hardware for citizen science, and (3) posing new scientific questions about the endocrine-disrupting properties of fracking chemicals.

National Media Coverage of Hydraulic Fracturing in the United States: Evaluation Using Human and Automated Coding Techniques
Benjamin Blair, Tanya Heikkila, Christopher M. Weible (2016). Risk, Hazards & Crisis in Public Policy, 114-128. 10.1002/rhc3.12097
Abstract:
This article offers an analysis of the national level news media coverage of the risks and benefits surrounding hydraulic fracturing, using two different content analysis methods. First, we complete a manual content analysis on 150 articles by the New York Times, the Wall Street Journal, and USA Today. We examine differences across these newspapers in reporting on environmental, public health, and economic risks and benefits, including the actors who the newspapers cite and whether these actors convey risks and benefits with certainty or uncertainty. Second, we use a semi-automated coding technique to examine coverage of environmental, environmental damage, public health, and economic topics in 15 nationally distributed newspapers. Overall, we conclude that the two approaches to studying national media content offer some similar insights into how the political leaning of newspapers may result in different coverage of hydraulic fracturing, but manual and automated codings each present distinct strengths and weaknesses in understanding media coverage of this contentious issue.

New horizon in energy: Shale gas
Selçuk Bilgen and İkbal Sarıkaya (2016). Journal of Natural Gas Science and Engineering, . 10.1016/j.jngse.2016.09.014
Abstract:
Today shale gas is one of the fastest growing propensities in onshore domestic oil and gas exploration and production. It is accepted to be unconventional source as the gas may be attached to or adsorbed onto organic matter. Its growing importance globally has led to the requirement for a deeper meaning of shale behavior. This study gives the properties, resources, reservoirs of shale gas and present information about technologies and the environmental impacts in the development of use of shale gas as energy source.

Repurposing of disused shale gas wells for subsurface heat storage: preliminary analysis concerning UK issues
Rob Westaway (2016). Quarterly Journal of Engineering Geology and Hydrogeology, 213-227. 10.1144/qjegh2016-016
Abstract:
Development of many wells is envisaged in the UK in coming decades to exploit the abundant shale gas resource as fuel and petrochemical feedstock. Forward planning is therefore warranted regarding reuse of the resulting subsurface infrastructure after gas production has ceased. It is shown that this infrastructure might be repurposed for borehole thermal energy storage (BTES). Preliminary calculations, assuming an idealized cycle of summer heat storage and winter heat extraction, indeed demonstrate annual storage of c. 6 TJ or c. 2 GWh of energy per BTES well. Summed over the anticipated well inventory, a significant proportion of the UK's future heat demand might thus be supplied. This form of BTES technology has particular relevance to the UK, where the shale resource is located in relatively densely populated areas; it is especially significant for Scotland, where the resource coincides with a particularly high proportion of the population and heat demand.

Abstract:
Shale gas is one of the most promising unconventional resources both in China and abroad. It is known as a form of self-contained source-reservoir system with large and continuous dimensions. Through years of considerable exploration efforts, China has identified three large shale gas fields in the Fuling, Changning and Weiyuan areas of the Sichuan Basin, and has announced more than 540 billion m3 of proven shale gas reserves in marine shale systems. The geological theories for shale gas development have progressed rapidly in China as well. For example, the new depositional patterns have been introduced for deciphering the paleogeography and sedimentary systems of the Wufeng shale and Longmaxi shale in the Sichuan Basin. The shale gas storage mechanism has been widely accepted as differing from conventional natural gas in that it is adsorbed on organic matter or a mineral surface or occurs as free gas trapped in pores and fractures of the shale. Significant advances in the techniques of microstructural characterization have provided new insights on how gas molecules are stored in micro-and nano-scale porous shales. Furthermore, newly-developed concepts and practices in the petroleum industry, such as hydraulic fracturing, microseismic monitoring and multiwell horizontal drilling, have made the production of this unevenly distributed but promising unconventional natural gas a reality. China has 10–36 trillion m3 of promising shale gas among the world's whole predicted technically recoverable reserves of 206.6 trillion m3. China is on the way to achieving its goal of an annual yield of 30–50 billion m3 by launching more trials within shale gas projects.

Abstract:
Understanding how the news media portray controversial natural resource issues is an important area of environmental policy research due to the media’s ability to influence public opinion and policymaking. Automated media coding is becoming increasingly used as an alternative or supplement to the human coding of these portrayals. However, the comparability of human versus automated coding of the news media has not been well documented. This research note provides a comparison of an automated method to human coding of newspaper articles on the controversial issue of hydraulic fracturing. It describes the methods and results of coding 1,037 articles from four newspapers in New York and Pennsylvania. This research note compares the automated method to a human coding method and describes the proportion of coverage of New York and Pennsylvania newspapers on economic, environmental, and social topics related to hydraulic fracturing.

Jasmin Cooper, Laurence Stamford, Adisa Azapagic (2016). Energy Technology, 772-792. 10.1002/ente.201500464
Abstract:
The growth of the shale gas industry in the US has raised expectations that other nations could boost domestic gas production, leading to lower energy prices and improved energy security. However, the degree to which the US experience is transferable to other countries is uncertain. Furthermore, sustainability implications of shale gas development remain largely unknown. In an attempt to find out if and how shale gas could be exploited in a sustainable way, this paper reviews the economic, environmental, and social aspects of shale gas. These include costs, energy security, employment, water and land pollution, greenhouse gas emissions, earthquakes, and public perception. The literature suggests that it is possible to develop shale gas in a sustainable way, but its future will depend on the industry being able to address the environmental concerns, the political will to see the industry through to maturity, and public support, with the latter most likely being the biggest determinant.

Reducing pollution at five critical points of shale gas production: Strategies and institutional responses
Terence J. Centner (2016). Energy Policy, 40-46. 10.1016/j.enpol.2016.03.045
Abstract:
While the public and governments debate the advisability of engaging in shale gas production, the United States has proceeded to develop its resources with an accompanying remarkable increase in natural gas production. The development of shale gas has not been without problems, and some countries have decided that shale gas production should not proceed until more is known about the accompanying health issues and environmental damages. From experiences in the United States, careful consideration of five critical points relating to shale gas production can form the basis for developing strategies for reducing discharges of pollutants: (1) casing and cementing, (2) handling wastewater, (3) venting and flaring, (4) equipment with air emissions, and (5) seismic events. For each strategy, institutional responses to markedly reduce the risks of harm to people and the environment are identified. These responses offer state and local governments ideas for enabling shale gas resources to be developed without sacrificing public health and environmental quality.

Daniel Wetherell and Darrick Evensen (2016). Energy Policy, 331-335. 10.1016/j.enpol.2016.04.028
Abstract:
The increasingly growing and controversial practice of natural gas development by horizontal drilling and high volume hydraulic fracturing (‘fracking’) faces a severe environmental insurance deficit at the industry level. Part of this deficit is arguably inherent to the process, whereas another part is caused by current risk information shortfalls on the processes and impacts associated with development. In the short and long terms, there are several conventional and unconventional methods by which industry-level and governmental-level policy can insure against these risks. Whilst academic attention has been afforded to the potential risks associated with unconventional natural gas development, little consideration has been given to the lack of insurance opportunities against these risks or to the additional risks promulgated by the dearth of insurance options. We chronicle the ways in which insurance options are limited due to unconventional gas development, the problems caused by lack of insurance offerings, and we highlight potential policy remedies for addressing these gaps, including a range of government- and industry-specific approaches.

Nanostructural control of methane release in kerogen and its implications to wellbore production decline
Tuan Anh Ho, Louise J. Criscenti, Yifeng Wang (2016). Scientific Reports, . 10.1038/srep28053
Abstract:
Despite massive success of shale gas production in the US in the last few decades there are still major concerns with the steep decline in wellbore production and the large uncertainty in a long-term projection of decline curves. A reliable projection must rely on a mechanistic understanding of methane release in shale matrix–a limiting step in shale gas extraction. Using molecular simulations, we here show that methane release in nanoporous kerogen matrix is characterized by fast release of pressurized free gas (accounting for ~30–47% recovery) followed by slow release of adsorbed gas as the gas pressure decreases. The first stage is driven by the gas pressure gradient while the second stage is controlled by gas desorption and diffusion. We further show that diffusion of all methane in nanoporous kerogen behaves differently from the bulk phase, with much smaller diffusion coefficients. The MD simulations also indicate that a significant fraction (3–35%) of methane deposited in kerogen can potentially become trapped in isolated nanopores and thus not recoverable. Our results shed a new light on mechanistic understanding gas release and production decline in unconventional reservoirs. The long-term production decline appears controlled by the second stage of gas release.

A reliable projection must rely on a mechanistic understanding of methane release in shale matrix–a limiting step in shale gas extraction. Using molecular simulations, we here show that methane release in nanoporous kerogen matrix is characterized by fast release of pressurized free gas (accounting for ~30–47% recovery) followed by slow release of adsorbed gas as the gas pressure decreases. The first stage is driven by the gas pressure gradient while the second stage is controlled by gas desorption and diffusion. We further show that diffusion of all methane in nanoporous kerogen behaves differently from the bulk phase, with much smaller diffusion coefficients. The MD simulations also indicate that a significant fraction (3–35%) of methane deposited in kerogen can potentially become trapped in isolated nanopores and thus not recoverable. Our results shed a new light on mechanistic understanding gas release and production decline in unconventional reservoirs. The long-term production decline appears controlled by the second stage of gas release.

Fracking in Tight Shales: What Is It, What Does It Accomplish, and What Are Its Consequences?
J. Quinn Norris, Donald L. Turcotte, Eldridge M. Moores, Emily E. Brodsky, John B. Rundle (2016). Annual Review of Earth and Planetary Sciences, 321-351. 10.1146/annurev-earth-060115-012537
Abstract:
Fracking is a popular term referring to hydraulic fracturing when it is used to extract hydrocarbons. We distinguish between low-volume traditional fracking and the high-volume modern fracking used to recover large volumes of hydrocarbons from shales. Shales are fine-grained rocks with low granular permeabilities. During the formation of oil and gas, large fluid pressures are generated. These pressures result in natural fracking, and the resulting fracture permeability allows oil and gas to escape, reducing the fluid pressures. These fractures may subsequently be sealed by mineral deposition, resulting in tight shale formations. The objective of modern fracking is to reopen these fractures and/or create new fractures on a wide range of scales. Modern fracking has had a major impact on the availability of oil and gas globally; however, there are serious environmental objections to modern fracking, which should be weighed carefully against its benefits.

A web-based multicriteria evaluation of spatial trade-offs between environmental and economic implications from hydraulic fracturing in a shale gas region in Ohio
X. Liu, P. V. Gorsevski, M. M. Yacobucci, C. M. Onasch (2016). Environmental Monitoring and Assessment, 376. 10.1007/s10661-016-5362-8
Abstract:
Planning of shale gas infrastructure and drilling sites for hydraulic fracturing has important spatial implications. The evaluation of conflicting and competing objectives requires an explicit consideration of multiple criteria as they have important environmental and economic implications. This study presents a web-based multicriteria spatial decision support system (SDSS) prototype with a flexible and user-friendly interface that could provide educational or decision-making capabilities with respect to hydraulic fracturing site selection in eastern Ohio. One of the main features of this SDSS is to emphasize potential trade-offs between important factors of environmental and economic ramifications from hydraulic fracturing activities using a weighted linear combination (WLC) method. In the prototype, the GIS-enabled analytical components allow spontaneous visualization of available alternatives on maps which provide value-added features for decision support processes and derivation of final decision maps. The SDSS prototype also facilitates nonexpert participation capabilities using a mapping module, decision-making tool, group decision module, and social media sharing tools. The logical flow of successively presented forms and standardized criteria maps is used to generate visualization of trade-off scenarios and alternative solutions tailored to individual user's preferences that are graphed for subsequent decision-making.

Abstract:
Facing with great pressure to feed the demand outstripping the supply situation as well as alleviate the energy pollution problem, China has accelerated the pace of shale gas exploration. During the 12th Five-Year-Plan (FYP) period, Chinese government and petroleum enterprises actively promoted the development of shale gas industry, and made certain progresses in various aspects. Meanwhile, a series of preferential and supportive policies were developed to encourage shale gas exploration. However, as the shale gas industry is still in the initial stage in China, there are many challenges and difficulties existing in shale gas development. This paper presents a systematical review on the current status and policies of shale gas industry in China, aiming to provide important reference to the policy-makers for introducing and improving policies. Firstly, the current status including progresses and difficulties is presented. Subsequently, the recent policies for shale gas development are reviewed. The analyses of current policies and implementation barriers are followed. Finally, specific policy suggestions are proposed and a general conclusion is drawn.

Abstract:
Automated monitoring devices are useful technologies for communities seeking to document and solve environmental problems. However, without deeper scrutiny of their design and deployment, there is a risk that they will fail to have the impact that many of their promoters intend. We develop a rubric for analysing how different kinds of monitoring devices help environmental advocates influence public debates. We apply this rubric in a study of environmental organizations in Pennsylvania that are choosing between recruiting volunteer citizen scientists and using automated sensor-based devices to gather water quality data in streams threatened by hydraulic fracturing for natural gas. Many organizations rely on volunteers using simple monitoring tools because they are affordable and produce easily managed data sets. An argument for this method of monitoring is that volunteering in the field also fosters citizen engagement in environmental debates. By comparison, we find the increased use of automated devices tends to reinforce hierarchies of expertise and constrains the agendas of nonprofessionals who participate in monitoring projects. We argue that these findings suggest that automated technologies, however effective they may be in gathering data on environmental quality, are not well designed to support broad public participation in environmental science and politics.

Abstract:
In the context of an application for a shale gas exploration license including hydraulic fracturing, the Geological Survey of Hessen (HLNUG) has grouped and ranked structural geological regions in terms of their shale gas potential and the function of overlying rocks as barriers. Tectonic and structural features as well as the type of reservoir have been examined. Rock units overlying the shale gas layers have been classified as hydrogeological units and divided into aquifers and hydraulic barriers. Possible effects on drinking water abstraction facilities, mineral springs and water for industrial use have also been estimated, followed by an analysis of competing requirements for land use. A potential for shale gas can only be identified in a region north of Kassel, covering about 16 % of the claim area. Approximately 65 % of this region is overlapped by protection areas for drinking water and mineral springs, nature reserves and many other areas of public interest.

Abstract:
X-ray microtomography (XMT) imaging combined with a three-dimensional (3D) computational fluid dynamics (CFD) modeling technique was used to study the effect of geochemical and geomechanical processes on fracture permeability in composite Portland cement–basalt caprock core samples. The effect of fluid density and viscosity and applied pressure gradient on fracture permeability was numerically studied by using fluids with varying density and viscosity and simulating two different pressure gradient conditions. After the application of geomechanical stress but before CO2-reaction, CFD revealed fluid flow increase, which resulted in increased fracture permeability. After CO2-reaction, XMT images displayed preferential precipitation of calcium carbonate within the fractures in the cement matrix and less precipitation in fractures located at the cement–basalt interface. CFD estimated changes in flow profile and differences in absolute values of flow velocity due to different pressure gradients. CFD was able to highlight the profound effect of fluid viscosity on velocity profile and fracture permeability. This study demonstrates the applicability of XMT imaging and CFD as powerful tools for characterizing the hydraulic properties of fractures in a number of applications like geologic carbon sequestration and storage, hydraulic fracturing for shale gas production, and enhanced geothermal systems.

The costs of avoiding environmental impacts from shale-gas surface infrastructure
Austin W. Milt, Tamara D. Gagnolet, Paul R. Armsworth (2016). Conservation Biology, n/a-n/a. 10.1111/cobi.12766
Abstract:
Growing energy demand has increased the need to manage conflicts between energy production and the environment. As an example, shale gas extraction requires substantial surface infrastructure, which fragments habitats, erodes soils, degrades freshwater systems, and displaces rare species. Strategic planning of shale gas infrastructure can reduce tradeoffs between economic and environmental objectives, but the specific nature of these tradeoffs is not known. Here we estimate the cost of avoiding impacts from land use change on forests, wetlands, rare species, and streams from shale energy development within lease-holds using newly developed optimization software for development planning. Our software adds explicit infrastructure development to the conservation planner's toolkit and enables the gas industry to explore more environmentally friendly options for infrastructure placement. On average up to 38% of aggregate environmental impacts of infrastructure could be avoided for 20% greater development costs by spatially optimizing infrastructure. However, we found tradeoffs between environmental impacts and costs among sites. Using visual inspection of sites before infrastructure optimization, we could often distinguish between sites that could avoid impacts at relatively low cost and those that could not. Reductions in a metric of aggregate environmental impact could be largely attributed to a subset of the environmental impacts on which planning was based. In conclusion, there are multiple ways that planners and regulators can estimate and use heterogeneous tradeoffs among development sites to create industry-wide improvements in environmental performance and do so at reasonable costs. Doing so may not be a low-effort endeavor and would be a change from the more common enforcement of uniform standards, but the results and software we provide here should help inform that transition and make it more compelling.

Jean-Pascal Gond, Luciano Barin Cruz, Emmanuel Raufflet, Mathieu Charron (2016). Journal of Management Studies, 330-363. 10.1111/joms.12166
Abstract:
How could a de facto moratorium on shale gas exploration emerge in Québec despite the broad adoption of fracking in North American jurisdictions, support from the provincial government and a favourable power position initially enjoyed by the oil and gas industry? This paper analyses this turn of events by studying how stakeholders from government, civil society, and industry mobilized modes of justification and forms of power with the aim to influence the moral legitimacy of the fracking technology during a controversy surrounding shale gas exploration. Combining Boltanski and Thévenot's economies of worth theory with Lukes’ concept of power, we analytically induced the justification of power mechanisms whereby uses of power become justified or ‘escape’ justification, and the power of justification mechanisms by which justifications alter subsequent power dynamics. We finally explain how these mechanisms contribute to explaining the controversy's ultimate outcome, and advance current debates on political corporate social responsibility.

Abstract:
Hydraulic fracturing has become a contentious issue around the globe. In the present study, using a sample of American adults (n = 412), the role of political orientation (conservative vs. liberal) and basic knowledge about fracking on fracking risk perception attitudes, fracking economic attitudes, energy reliance attitudes, trust of energy information sources, and preferred dwelling distance from energy operations was investigated. Basic knowledge about hydraulic fracturing as a possible moderating mechanism was also explored. Correlational and regression results revealed that political ideology and basic fracking knowledge are key predictors of fracking and energy source attitudes, and that the nature of the relation between ideology and fracking risk perceptions, fracking economic attitudes, reliance on natural gas, wind and solar, and distrust of government agencies, are influenced by an individual’s basic knowledge about fracking.

Abstract:
Unconventional oil and gas development (UOGD) has recently become the subject of much research. However, neglected during this effort are the leases signed between landowner and industry that act as the foundation for development and may influence the distribution and intensity of associated impacts. These leases amount to an inscribed collection of rules and practices that define a wide variety of conditions related to development. The temporal and geographic distribution of lease terms may directly influence a number of phenomena of interest to scholars studying UOGD. In order to advance research on the subject, we (1) describe and outline research topics that could be addressed by applying social science methods to the analysis of leases and specific lease provisions, (2) discuss challenges and strategies for data collection and (3) review policy implications of lease related research.

Abstract:
The body of science evaluating the potential impacts of unconventional natural gas development (UNGD) has grown significantly in recent years, although many data gaps remain. Still, a broad empirical understanding of the impacts is beginning to emerge amidst a swell of research. The present categorical assessment provides an overview of the peer-reviewed scientific literature from 2009–2015 as it relates to the potential impacts of UNGD on public health, water quality, and air quality. We have categorized all available original research during this time period in an attempt to understand the weight and direction of the scientific literature. Our results indicate that at least 685 papers have been published in peer-reviewed scientific journals that are relevant to assessing the impacts of UNGD. 84% of public health studies contain findings that indicate public health hazards, elevated risks, or adverse health outcomes; 69% of water quality studies contain findings that indicate potential, positive association, or actual incidence of water contamination; and 87% of air quality studies contain findings that indicate elevated air pollutant emissions and/or atmospheric concentrations. This paper demonstrates that the weight of the findings in the scientific literature indicates hazards and elevated risks to human health as well as possible adverse health outcomes associated with UNGD. There are limitations to this type of assessment and it is only intended to provide a snapshot of the scientific knowledge based on the available literature. However, this work can be used to identify themes that lie in or across studies, to prioritize future research, and to provide an empirical foundation for policy decisions.

Nonita T. Yap (2016). Impact Assessment and Project Appraisal, 97-109. 10.1080/14615517.2016.1176405
Abstract:
The growth of unconventional shale gas development has been accompanied by controversy over its environmental and social impacts. This paper reviews recent literature to clarify what is known and not known about the physical, chemical and toxicological properties of the process chemicals and wastewaters generated in hydraulic fracturing, the mechanisms and pathways by which they enter surface water and groundwater aquifers and the risks posed to human and ecosystem health. Assessing the impacts of unconventional shale gas development is clearly constrained by a lack of baseline information, complex hydrogeological histories for natural migration of hydrocarbons, lack of tracers to monitor and verify the source, timing and mechanism of contaminant migration into water resources. This is compounded by lack of transparency and accountability in policy decisions. The paper argues that managing the social and environmental risks of unconventional shale gas development calls for a new generation of impact assessment, one that marries the ideals of strategic environmental assessment, cumulative effects assessment, backcasting and deliberative and inclusive processes of community engagement towards collective risk management.

Abstract:
This paper mainly discusses the industrialization progress, “sweet spot” evaluation criterion, E&P technologies, success experiences, challenges and prospects of China's shale gas. Based on the geologic and engineering parameters of the Fuling, Changning and Weiyuan shale gas fields in the Sichuan Basin, this paper points out that China's shale gas has its particularity. The discoveries of super-giant marine shale gas fields with high evolution degree (Ro=2.0%−3.5%) and ultrahigh pressure (pressure coefficient=1.3−2.1) in southern China is of important scientific significance and practical value to ancient marine shale gas exploration and development to China and even the world. It's proposed that shale gas “sweet spots” must be characterized by high gas content, excellent frackability and good economy etc. The key indicators to determine the shale gas enrichment interval and trajectory of horizontal wells include “four highs”, that is high TOC (>3.0%), high porosity (>3.0%), high gas content (>3.0 m3/t) and high formation pressure (pressure coefficient>1.3), and “two well-developed” (well-developed beddings and well-developed micro-fractures). It's suggested that horizontal well laneway be designed in the middle of high pressure compartment between the Upper Ordovician Wufeng Formation and Lower Silurian Longmaxi Formation. The mode of forming “artificial shale gas reservoir” by “fracturing micro-reservoir group” is proposed and the mechanisms of “closing-in after fracturing, limiting production through pressure control” are revealed. Several key technologies (such as three-dimensional seismic survey and micro-seismic monitoring of fracturing, horizontal wells, “factory-like” or industrialized production mode, etc.) were formed. Some successful experiences (such as “sweet spot” selection, horizontal well laneway control, horizontal length optimization and “factory-like” production mode, etc.) were obtained. The four main challenges to realize large-scale production of shale gas in China include uncertainty of shale gas resources, breakthroughs in key technologies and equipment of shale gas exploration and development below 3 500 m, lower cost of production, as well as water resources and environment protection. It is predicted that the recoverable resources of the Lower Paleozoic marine shale gas in southern China are approximately 8.8×1012 m3, among which the recoverable resources in the Sichuan Basin are 4.5×1012 m3 in the favorable area of 4.0×104 km2. The productivity of (200−300)×108 m3/a is predicted to be realized by 2020 when the integrated revolution of “theory, technology, production and cost” is realized in Chinese shale gas exploration and development. It is expected in the future to be built “Southwest Daqing Oilfield (Gas Daqing)” in Sichuan Basin with conventional and unconventional natural gas production.

Based on the geologic and engineering parameters of the Fuling, Changning and Weiyuan shale gas fields in the Sichuan Basin, this paper points out that China's shale gas has its particularity. The discoveries of super-giant marine shale gas fields with high evolution degree (Ro=2.0%−3.5%) and ultrahigh pressure (pressure coefficient=1.3−2.1) in southern China is of important scientific significance and practical value to ancient marine shale gas exploration and development to China and even the world. It's proposed that shale gas “sweet spots” must be characterized by high gas content, excellent frackability and good economy etc. The key indicators to determine the shale gas enrichment interval and trajectory of horizontal wells include “four highs”, that is high TOC (>3.0%), high porosity (>3.0%), high gas content (>3.0 m3/t) and high formation pressure (pressure coefficient>1.3), and “two well-developed” (well-developed beddings and well-developed micro-fractures). It's suggested that horizontal well laneway be designed in the middle of high pressure compartment between the Upper Ordovician Wufeng Formation and Lower Silurian Longmaxi Formation. The mode of forming “artificial shale gas reservoir” by “fracturing micro-reservoir group” is proposed and the mechanisms of “closing-in after fracturing, limiting production through pressure control” are revealed. Several key technologies (such as three-dimensional seismic survey and micro-seismic monitoring of fracturing, horizontal wells, “factory-like” or industrialized production mode, etc.) were formed. Some successful experiences (such as “sweet spot” selection, horizontal well laneway control, horizontal length optimization and “factory-like” production mode, etc.) were obtained. The four main challenges to realize large-scale production of shale gas in China include uncertainty of shale gas resources, breakthroughs in key technologies and equipment of shale gas exploration and development below 3 500 m, lower cost of production, as well as water resources and environment protection. It is predicted that the recoverable resources of the Lower Paleozoic marine shale gas in southern China are approximately 8.8×1012 m3, among which the recoverable resources in the Sichuan Basin are 4.5×1012 m3 in the favorable area of 4.0×104 km2. The productivity of (200−300)×108 m3/a is predicted to be realized by 2020 when the integrated revolution of “theory, technology, production and cost” is realized in Chinese shale gas exploration and development. It is expected in the future to be built “Southwest Daqing Oilfield (Gas Daqing)” in Sichuan Basin with conventional and unconventional natural gas production.

Abstract:
Unconventionally-produced crude oils, i.e., Bakken oil and bitumen diluted for transport and known as dilbit, have become prominent components of the North American petroleum industry. Spills of these oils have occurred during transport from production areas to refineries via pipeline, rail, and barge. Some of their physical and chemical properties are distinct and present new challenges in mitigating spill impacts on people and the environment. This paper describes the adaptation of a qualitative risk assessment process to improve spill preparedness and response decisions for these oils when transported in an estuarine area. The application of this collaborative, interdisciplinary process drew upon a literature review, the local knowledge and experience of a broad set of decision makers, practitioners, and technical experts who developed consensus-based recommendations aimed at improving response to spills of these oils. Two emphasized components of this consensus ecological risk assessment (CERA) concerned risks: (1) to human health and safety and (2) from spilled oil and the associated response actions on endangered species. Participants in the process defined levels of concern associated with Bakken and dilbit oils relative to a set of response actions in freshwater, brackish and saltwater habitats and on resources at risk.

Hydraulic fracturing for natural gas: impact on health and environment
David O. Carpenter (2016). Reviews on Environmental Health, . 10.1515/reveh-2015-0055
Abstract:
Shale deposits exist in many parts of the world and contain relatively large amounts of natural gas and oil. Recent technological developments in the process of horizontal hydraulic fracturing (hydrofracturing or fracking) have suddenly made it economically feasible to extract natural gas from shale. While natural gas is a much cleaner burning fuel than coal, there are a number of significant threats to human health from the extraction process as currently practiced. There are immediate threats to health resulting from air pollution from volatile organic compounds, which contain carcinogens such as benzene and ethyl-benzene, and which have adverse neurologic and respiratory effects. Hydrogen sulfide, a component of natural gas, is a potent neuro- and respiratory toxin. In addition, levels of formaldehyde are elevated around fracking sites due to truck traffic and conversion of methane to formaldehyde by sunlight. There are major concerns about water contamination because the chemicals used can get into both ground and surface water. Much of the produced water (up to 40% of what is injected) comes back out of the gas well with significant radioactivity because radium in subsurface rock is relatively water soluble. There are significant long-term threats beyond cancer, including exacerbation of climate change due to the release of methane into the atmosphere, and increased earthquake activity due to disruption of subsurface tectonic plates. While fracking for natural gas has significant economic benefits, and while natural gas is theoretically a better fossil fuel as compared to coal and oil, current fracking practices pose significant adverse health effects to workers and near-by residents. The health of the public should not be compromized simply for the economic benefits to the industry.

Abstract:
Strategic insights into the previous conflict between the Elsipogtog First Nation and the New Brunswick (NB) Provincial Government are presented using a formal conflict resolution technique. The conflict surrounds the prospect of widespread hydraulic fracturing in NB, one of Canada's Maritime provinces on the east coast of the country. The hydraulic fracturing technique, used for mining natural gas trapped in shale rock formations, has recently received much attention. The process is strongly opposed by some groups, including the Elsipogtog First Nation, primarily due to the potential environmental impacts associated with the technique. Through the application of the Graph Model for Conflict Resolution, it is found that the status quo at the time of the conflict was the most likely outcome in this conflict. The previous Conservative New Brunswick government had a great deal of power in this conflict and it had demonstrated its intention to develop the shale gas in the province in the face of much civil unrest. It is discovered, however, that there is a potential resolution to the conflict that will appease the residents of NB, if a moratorium is issued concerning hydraulic fracturing.

Adequacy of Current State Setbacks for Directional High-Volume Hydraulic Fracturing in the Marcellus, Barnett, and Niobrara Shale Plays

Abstract:
Background: There is an increasing awareness of the multiple potential pathways leading to human health risks from hydraulic fracturing. Setback distances are a legislative method to mitigate potential risks. Objectives: We attempted to determine whether legal setback distances between well-pad sites and the public are adequate in three shale plays. Methods: We reviewed geography, current statutes and regulations, evacuations, thermal modeling, air pollution studies, and vapor cloud modeling within the Marcellus, Barnett, and Niobrara Shale Plays. Discussion: The evidence suggests that presently utilized setbacks may leave the public vulnerable to explosions, radiant heat, toxic gas clouds, and air pollution from hydraulic fracturing activities. Conclusions: Our results suggest that setbacks may not be sufficient to reduce potential threats to human health in areas where hydraulic fracturing occurs. It is more likely that a combination of reasonable setbacks with controls for other sources of pollution associated with the process will be required.
