Unconventional Oil and Gas Resources Handbook

Unconventional Oil and Gas Resources Handbook: Evaluation and Development is a must-have, helpful handbook that brings a wealth of information to engineers and geoscientists. Bridging between subsurface and production, the handbook provides engineers and geoscientists with effective methodology to better define resources and reservoirs. Better reservoir knowledge and innovative technologies are making unconventional resources economically possible, and multidisciplinary approaches in evaluating these resources are critical to successful development. Unconventional Oil and Gas Resources Handbook takes this approach, covering a wide range of topics for developing these resources including exploration, evaluation, drilling, completion, and production. Topics include theory, methodology, and case histories and will help to improve the understanding,integrated evaluation, and effective development of unconventional resources.

• Presents methods for a full development cycle of unconventional resources, from exploration through production
• Explores multidisciplinary integrations for evaluation and development of unconventional resources and covers a broad range of reservoir characterization methods and development scenarios
• Delivers balanced information with multiple contributors from both academia and industry
• Provides case histories involving geological analysis, geomechanical analysis, reservoir modeling, hydraulic fracturing treatment, microseismic monitoring, well performance and refracturing for development of unconventional reservoirs

(Primary): Petroleum Engineers, Geologists, Reservoir Engineers, Drilling Engineers, Natural Gas Engineers, Well Designers, Well Managers, Petrophysicists, Production Engineers, and Completion Engineers; (Secondary): Graduate level Petroleum Engineering Students
