Since the beginning of the US shale gas revolution in 2005, the development of unconventional oil and gas resources has gathered tremendous pace around the world. This book provides a comprehensive overview of the key geologic, geophysical, and engineering principles that govern the development of unconventional reservoirs. The book begins with a detailed characterization of unconventional reservoir rocks: their composition and microstructure, mechanical properties, and the processes controlling fault slip and fluid flow. A discussion of geomechanical principles follows, including the state of stress, pore pressure, and the importance of fractures and faults. After reviewing the fundamentals of horizontal drilling, multi-stage hydraulic fracturing, and stimulation of slip on pre-existing faults, the key factors impacting hydrocarbon production are explored. The final chapters cover environmental impacts and how to mitigate hazards associated with induced seismicity. This text provides an essential overview for students, researchers, and industry professionals interested in unconventional reservoirs.

Situated among the North Cascade Mountains of Washington State, in the Glacier Peak Wilderness Area, Miners Ridge contains vast quantities of copper. Kennecott Copper Corporation's plan to develop an open-pit mine there was, when announced in 1966, the first test of the mining provision of the Wilderness Act passed by Congress in 1964. The battle over the proposed "Open Pit, Big Enough to Be Seen from the Moon," as activists called it, drew the attention of both local and national conservationists, who vowed to stop the desecration of one of the West's most scenic places. Kennecott Copper had the full force of the law and mining industry behind it in asserting its extractive rights. Meanwhile the U.S. Forest Service was determined to defend its authority to manage wilderness. An Open Pit Visible from the Moon tells the story of this historic struggle to define the contours of the Wilderness Act-its possibilities and limits. Combining rigorous analysis and deft storytelling, Adam M. Sowards re-creates the contest between Kennecott and its shareholders on one hand and activists on the other, intent on maintaining wilderness as a place immune to the calculus of profit. A host of actors cross these pages-from cabinet secretaries and a Supreme Court justice to local doctors and college students-all contributing to a drama that made Miners Ridge a cause cElEbre for the nation's wilderness movement. As locals testified at public hearings and writers penned profiles in the nation's magazines and newspapers, the volatile political economy of copper proved equally influential in frustrating Kennecott's plans. No law or court ruling could keep Kennecott from mining copper, but the pit was never dug. Identifying the contingent factors and forces that converged and coalesced in this case, Sowards's narrative recalls a critical moment in the struggle over the nation's wild places, even as it puts the unpredictability of history on full display.

The hands of Cornish miners bore scars of one of the most sophisticated traditions of hard-rock mining in the world. Toughened "Cousin Jacks" brought generations of toilsome underground experience to the Americas from one of the oldest mining regions of the world. Once here, their skill with granite and ore won their fame as the industrial elite of western mining camps. Heirs of a perfected system of excavation, a valuable terminology, and the technical edge of a culture immersed in sinkings, stopes, and winzes, they were the world's best hard-rock miners. Pioneers in American mine operation, Cornish miners utilized tribute pay to raise output and made themselves partners with a grueling industry. Expertise made them company men, superintendents, captains, and drillers, with their success dependent almost entirely on their own initiative, coolness, and skill. They are part of a culture that has survived because its very roughness gave a resilience and durability that could be transplanted and take root in an alien soil. The courage and determination of these "Cousin Jacks" in their struggle against overwhelming odds is dramatically illustrated in numerous personal stories. The Atlantic crossing, and the journey overland to the new mining districts, were exhausting trials. Although their skill in working with rock and water was soon recognized, the extremes of weather and temperature, strange sicknesses, the constant danger of accidents, and the lawlessness of the camps, all made life hard to endure. Many did not survive to send home for their families, yet the majority persevered to spread their legendary mining skills and to bring social as well as religious stability to mining areas that extended from Wisconsin to California. In the continent-wide search for bonanzas, Cornish miners and their families played a vital part in the opening-up of the American West, and in the shaping of modern industrial America. The author follows them across the Atlantic to the lead mines and farms of Wisconsin, along the trails to Oregon and Death Valley, the Sierras and the Sacramento in California, then to the copper and iron ranges in the Hiawatha country of Upper Michigan; from there to the silver and gold canyons of the Rockies and the notorious Comstock Lode in Nevada, and finally to the deserts of Utah, Idaho, and Arizona. Originally published in 1967, this new edition contains an updated introduction by Dr. Todd. With extensive footnotes and index, handsomely printed on acid-free paper stock with cloth cover which is stamped in gold foil on the spine and cover.
