Description

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 experienced in conventional oil and gas exploitation and development to acquire practical knowledge of the unconventional realm.

Unconventional Oil and Gas Resources: Exploitation and Development provides a comprehensive understanding of the latest advances in the exploitation and development of unconventional resources. With an emphasis on shale, this book:

  • Addresses all aspects of the exploitation and development process, from data mining and accounting to drilling, completion, stimulation, production, and environmental issues
  • Offers in-depth coverage of sub-surface measurements (geological, geophysical, petrophysical, geochemical, and geomechanical) and their interpretation
  • Discusses the use of microseismic, fiber optic, and tracer reservoir monitoring technologies and JewelSuite™ reservoir modeling software
  • Presents the viewpoints of internationally respected experts and researchers from leading exploration and production (E&P) companies and academic institutions
  • Explores future trends in reservoir technologies for unconventional resources development

Unconventional Oil and Gas Resources: Exploitation and Development aids geologists, geophysicists, petrophysicists, geomechanic specialists, and drilling, completion, stimulation, production, and reservoir engineers in the environmentally safe exploitation and development of unconventional resources like shale.

Reviews

"This cornerstone-edited volume sets a benchmark for understanding the complexity of unconventional oil and gas resources. The breath of the topics covered and level within each topic have set a high bar for any future book in this space. If you are in this business, you need to have this book. If you are considering this business, you could stumble without this book. It should be required reading at any university with programs in petroleum science. For those that don’t know the two editors, Usman Ahmed and Dr. Nathan Meehan, we are getting a volume that is scrutinized by two top-class industry scientists with vast technology insight who know the topics covered. In my judgment, if you could only have one book on this topic, this is it."

—Dr. Raymond Levey, Director, Energy and Geoscience Institute, University of Utah, Salt Lake City, USA

"The authors should be commended for carefully and painstakingly assembling this comprehensive collection of background data, methods, and workflows current to the industry with insight into potential areas of ongoing research and investigations (e.g., emerging resource areas, formation evaluation, data analytics, etc.). For the practitioner, this text serves as a valuable reference tool and guide. For the researcher, this text provides insight into current methods and workflows, and aids further investigations into emerging areas of unconventional resources. Finally, this text is an invaluable resource to accompany advanced undergraduate and postgraduate unconventional resources coursework and lectures. Heretofore, a comprehensive unconventional resources text such as this has been unavailable."

—Dr. Raymond Johnson, Jr., Senior Lecturer, University of Queensland, and Adjunct Associate Professor, University of Adelaide, Australia
