The development of unconventional oil and gas shales using hydraulic fracturing and directional drilling is currently a focal point of energy and climate change discussions. While this technology has provided access to substantial reserves of oil and gas, the need for large quantities of water, emissions, and infrastructure raises concerns over the environmental impacts. Written by an international consortium of experts, this book provides a comprehensive overview of the extraction from unconventional reservoirs, providing clear explanations of the technology and processes involved. Each chapter is devoted to different aspects including global reserves, the status of their development and regulatory framework, water management and contamination, air quality, earthquakes, radioactivity, isotope geochemistry, microbiology, and climate change. Case studies present baseline studies, water monitoring efforts and habitat destruction. This book is accessible to a wide audience, from academics to industry professionals and policy makers interested in environmental pollution and petroleum exploration.

The chapters in this volume represent the latest thinking on the development and exploration of unconventional energy resources in the U.S., Canada, Australia, Europe, Russia, Asia Pacific, Middle East, Latin America, and Africa and shed light on its potential and future prospects in these respective regions. The diversity of thinking about the “shale revolution” is also evident in our case studies. Throughout many countries in Europe for example, there is a strong preference for investment in renewable sources of energy over the fossil fuels. In addition to environmental concerns, the falling price of renewables, have also made them more attractive financially. Consequently, global investment in renewables is outpacing that of fossil fuel two to one. Watching this trend, in 2017, the Chinese government has pledged to invest $360 billion on renewable energy. This would make China the largest investor in development of renewables in the world. Other obstacles to development of shale oil and gas in other parts of the world include, lack of adequate shale resources (Africa), the abundance of conventional energy resources (Middle East and North Africa), high cost of production (Russia, China, Japan) and political opposition to hydraulic fracturing (France and Poland). Despite these sentiments the economic imperatives (providing employment) also play a significant role in determining the future prospects for unconventional energy resources globally.

This book discusses the economic, political, and environmental issues surrounding the international exploration and exploitation of conventional and unconventional natural gas. Shale gas development in recent years has changed the energy discussion in the US as existing reserves of natural gas coupled with horizontal drilling and hydraulic fracturing make exploitation of these reserves economically feasible; the discussion is quickly becoming international in scope. The potential expansion of natural gas development impacts many regions of the globe and spans multiple perspectives. In a volatile international climate, one of intense geopolitical conflict between Russia and the West, economic slowdowns in Europe and China, military conflicts in the Middle East and northern Africa, and widening income disparity in the U.S., a relatively inexpensive and plentiful energy source like shale gas could play a key role in mitigating such conflicts. In an energy interdependent global community, however, multiple factors such as oil prices, differing rates of exploration, environmental concerns, strategic initiatives, institutional changes, legal and regulatory issues, and actions of the nations involved all have the potential to influence future outcomes. This book discusses each of these in turn, detailing the issues most prevalent in each geographical area. The first volume to provide a comprehensive global view of the impacts of shale gas development, this book fills a gap in the current research literature, providing vital information for the scholarly community and the public alike. This book will be of interest to researchers and students of economics, energy policy, public administration, and international relations as well as policy makers and residents of the regions that are experiencing shale gas development.

The emergence of unconventional oil and gas extraction, known as the "shale revolution", since 2008 has fundamentally reshaped the global energy sector. This revolution, driven by technological advancements in hydraulic fracturing and horizontal drilling, has unlocked vast reserves of oil and gas previously deemed inaccessible.

This book delves deeply into the transformative impact of unconventional resources on international energy markets and policies, providing a comprehensive analysis of their significance. Written by over 20 experts in oil and gas law, the book offers a rich, multidisciplinary perspective. It covers topics that are "horizontal" and cut across various jurisdictions, providing a comparative approach that spans 11 different countries, including the USA, Canada, Argentina, Brazil, Colombia, Mexico, the UK, Algeria, Libya, China, and Germany. This extensive analysis ensures a broad understanding of the global landscape of unconventional resources. Main themes include: · Global Impact: Unconventional resources have not only transformed the United States into a leading oil and gas producer but have also significantly influenced energy strategies worldwide. Countries across North America, South America, Europe, and Asia have adopted various strategies to harness these resources, reshaping the global energy market. · Policy Considerations: Key policy issues addressed in the book include the environmental and social impacts of unconventional resource extraction. Topics such as water management, the coexistence of drilling operations with other land uses, and the social implications of resource extraction are thoroughly examined. · Legal Framework: The book explores the complex legal landscape governing unconventional operations, delves into stakeholder dynamics, regulatory frameworks, and the intricacies of legal provisions that vary from one jurisdiction to another. · Geographical Analysis: In its second part, the book provides an in-depth analysis of specific country regulations. This section offers comparative insights into the regulatory approaches of eleven countries, highlighting both common challenges and unique strategies. The book concludes by exploring lessons learned and future perspectives within the framework of the energy trilemma—balancing energy security, environmental sustainability, and economic affordability. It emphasizes the transformative impact of unconventional resources on energy independence and security, while also addressing the contentious environmental considerations that accompany such developments. Overall, this book aims to equip readers with a comprehensive understanding of the legal and regulatory landscape surrounding unconventional oil and gas resources.

Oil and gas well completion and stimulation technologies to develop unconventional hydrocarbon resources in the United States have evolved over the past several decades, particularly in relation to the development of shale oil and shale gas. Shale oil and shale gas resources and the technology associated with their production are often termed "unconventional" because the oil and gas trapped inside the shale or other low-permeability rock formation cannot be extracted using conventional technologies. Since about 2005, the application of these technologies to fields in the U.S. have helped produce natural gas and oil in volumes that allowed the country to reduce its crude oil imports by more than 50% and to become a net natural gas exporter. The regional and national economic and energy advances gained through production and use of these resources have been accompanied, however, by rapid expansion of the infrastructure associated with the development of these fields and public concern over the impacts to surface- and groundwater, air, land, and communities where the resources are extracted. The intent of the first day of the workshop of the National Academies of Sciences, Engineering, and Medicine's Roundtable on Unconventional Hydrocarbon Development was to discuss onshore unconventional hydrocarbon development in the context of potential environmental impacts and the ways in which the risks of these kinds of impacts can be managed. Specifically, the workshop sought to examine the lifecycle development of these fields, including decommissioning and reclamation of wells and related surface and pipeline infrastructure, and the approaches from industry practice, scientific research, and regulation that could help to ensure management of the operations in ways that minimize impacts to the environment throughout their active lifetimes and after operations have ceased. This publication summarizes the presentations and discussions from the workshop.

This book provides a systematic scientific approach to the understanding of hydraulic fracturing (fracking) as a hydrocarbon extraction technology and its impact on the environment. The book addresses research from the past decade to assess how fracking can affect air, water, landscapes and ecosystems, and presents the subject in the context of the history of fracking and shale gas development in the United States, describing what is known and not known about environmental impacts, and the broader implications of fossil energy use, climate change, and technology development. In 9 chapters, the author lays out how and why hydraulic fracturing was developed, what driving forces existed at the beginning of the so-called "shale revolution", how success was achieved, and when and why public acceptance of the technology changed. The intended audience is scientific people who are concerned about fracking, but perhaps do not know all that much about it. It is also intended for lay people who would be interested in understanding the technical details of the process and what effects it might or might not be having on the environment. The book is written at a level that is both understandable and technically correct. A further goal is to give some useful insights even to experienced petroleum geologists and engineers who have been doing fracking for many years.

This book examines the economics and related impacts of unconventional shale gas development. While focusing on the Marcellus and Utica Shales in the Mid-Atlantic region, additional insights from other regions are included to provide a broader view of these issues. Shale gas development in recent years has changed the energy discussion in the US, as existing reserves of natural gas coupled with horizontal drilling and hydraulic fracturing make exploitation of these reserves economically feasible. The importance of natural gas is seen as likely to continue to expand over the coming years, and is expected to increase even further with environmental considerations, such as greenhouse gas emissions. Horizontal drilling and hydraulic fracturing producing natural gas from deposits such as the Marcellus Shale is making the US a net producer of natural gas. Previous studies have examined the economic impact of exploration and production in the region. Other studies have addressed legal, environmental, biodiversity, and public health impacts of unconventional shale development. This is the first volume to focus solely on the economics and related financial impacts of this development. This book not only fills the research gap, but also provides information that policy makers and the public need to better understand this pressing issue.
