Environmental and Health Issues in Unconventional Oil and Gas Development offers a unique, non-partisan perspective relevant to the use of directional drilling and hydraulic fracturing, presenting clear and frank discussions on implications for a variety of stakeholders involved in unconventional oil and shale gas development. Much has changed since the first edition, including how UOGD is performed, changes in monitoring and control technologies, and new issues raised by both government and non-government stakeholders. The contributing authors address a wide range of relevant topics. The economics of hydraulic fracturing are discussed. Methane emissions, decarbonization, and responsibly sourced gas are explored in depth. The authors also look closely at climate risk and risk mitigation. Water issues are covered with a review of water quality impacts along with waste issues. This is followed by a detailed examination of health and safety in regard to occupational health, public health, risk perception, risk communication, and transportation. Finally, the editors wrap up with important discussions on environmental justice and environmental, social, and corporate governance. Readers will find much to consider and apply to their own work within this reference on the critical environmental issues facing the unconventional oil and gas industry.• Serves as a collective, up-to-date resource for academics and professionals in the oil and gas, environmental, health, and safety industries, as well as environmental scientists and policymakers• Features a multi-disciplinary and expert group of chapter authors from academia, non-governmental organizations, governmental agencies, and the oil and gas industry• Provides thoughtful discussion of the ongoing emissions intensity reduction in unconventional oil and gas from a combination of regulation, technology evolution, and voluntary efforts by operators

As the shale revolution continues in North America, unconventional resource markets are emerging on every continent. In the next eight to ten years, more than 100,000 wells and one- to two-million hydraulic fracturing stages could be executed, resulting in close to one trillion dollars in industry spending. This growth has prompted professionals ex

A comprehensive overview of the key geologic, geomechanical and engineering principles that govern the development of unconventional oil and gas reservoirs. Covering hydrocarbon-bearing formations, horizontal drilling, reservoir seismology and environmental impacts, this is an invaluable resource for geologists, geophysicists and reservoir engineers.

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.

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.
