Air and Gas Drilling Manual, Fourth Edition: Applications for Oil, Gas and Geothermal Fluid Recovery Wells, and Specialized Construction Boreholes, and the History and Advent of the Directional DTH delivers the fundamentals and current methods needed for engineers and managers engaged in drilling operations. Packed with updates, this reference discusses the engineering modelling and planning aspects of underbalanced drilling, the impacts of technological advances in high angle and horizontal drilling, and the importance of new production from shale. in addition, an in-depth discussion is included on well control model planning considerations for completions, along with detailed calculation examples using Mathcad. This book will update the petroleum and drilling engineer with a much-needed reference to stay on top of drilling methods and new applications in today's operations. - Provides key drilling concepts and applications, including unconventional activity and directional well by gas drilling - Updated with new information and data on managed pressure drilling, foam drilling, and aerated fluid drilling - Includes practical appendices with Mathcad equation solutions

William C. Lyons, Ph.D., P.E. (retired), holds nine patents in industrial drilling and has been responsible for the development of several important innovations in drilling and production technology. He is the lead Editor of the Standard Handbook of Petroleum and Gas Engineering, 3rd edition, publishing with Elsevier and co-author of several other professional books in drilling and production engineering for the petroleum industry. Dr. Lyons was a Professor in Petroleum Engineering and in Mechanical Engineering at the New Mexico Institute of Mining and Technology for 30 years. He also served two one-year tours as a Distinguished Visiting Professor in Mechanical Engineering at the U.S. Air Force Academy in Colorado Springs during his academic career. Since retiring from teaching, Dr. Lyons is currently a Technical Learning Advisor with Chevron's Clear Leader Center in Houston, TX.
