Abstract:
Fracking has the potential to extract hydrocarbons from previously inaccessible sources of gas and oil, but is regularly in the news because of environmental concerns surrounding the process. First used commercially in the mid-20th Century, only recently has fracking been deployed on a large scale, revolutionising the energy industry in the USA. As more nations seek to adopt or ban fracking, do the economic benefits outweigh the environmental costs? Presenting both sides of the debate, this latest volume of Issues in Environmental Science and Technology draws on a wealth of international expertise, ranging from the oil and gas industry to Friends of the Earth. The technology of fracking is examined in detail, as well as the associated economic, societal and global climate change considerations. Individual chapters focus on exploration for unconventional hydrocarbons, the hydrogeological aspects and risks of water contamination, coal seam gas extraction in Australia and current developments in China. Anyone wishing to gain a balanced view of hydraulic fracturing will benefit from reading this book, which is aimed at researchers in academia and industry, policy makers, environmental science students and the interested layman.

Summary

Fracking has the potential to extract hydrocarbons from previously inaccessible sources of gas and oil, but is regularly in the news because of environmental concerns surrounding the process. First used commercially in the mid-20th Century, only recently has fracking been deployed on a large scale, revolutionising the energy industry in the USA. As more nations seek to adopt or ban fracking, do the economic benefits outweigh the environmental costs? Presenting both sides of the debate, this latest volume of Issues in Environmental Science and Technology draws on a wealth of international expertise, ranging from the oil and gas industry to Friends of the Earth. The technology of fracking is examined in detail, as well as the associated economic, societal and global climate change considerations. Anyone wishing to gain a balanced view of hydraulic fracturing will benefit from reading this book, which is aimed at researchers in academia and industry, policy makers, environmental science students and the interested layman.


Author Notes

Issues in Environmental Science and Technology are published twice a year, with each Issue addressing a specific theme or topic. Written by world experts in their specialist fields, this series presents a multi-disciplinary approach. In addition to covering the chemistry of environmental processes, the series focuses on the broader economic, legal and political aspects, and provides assessments of possible practical solutions to perceived environmental problems.

Choice Review

Fracking is the procedure for creating fractures in rocks by injecting fluids under high pressure into cracks in order to make them wider. This collection of eight essays by 13 authors on the subject of fracking focuses primarily on stimulating production of natural gas trapped in shale. It looks at both favorable and unfavorable aspects of fracking from a wide variety of viewpoints. These include many geological, economic, and environmental factors. Each chapter goes into great depth in examining a particular part of the picture. The two chapters devoted to drilling and production procedures give details hard to find in the general literature, including just what is in the hydraulic fracturing fluids. The discussion of both short-term and long-term global economic considerations, although highly technical, looks closely at both potential benefits and potential downsides of increased reliance on shale gas. Environmental aspects, including impacts on global climate change, receive comments from both pro-industry and pro-environment sides. Though the emphasis is on Great Britain, the US, and China, one chapter addresses coal-seam gas recovery in Australia. References at the end of each article are extensive. Summing Up: Recommended. Upper-division undergraduates through professionals/practitioners. --Charles William Dimmick, emeritus, Central Connecticut State University
