Formulas and Calculations for Drilling, Production, and Workover, All the Formulas You Need to Solve Drilling and Production Problems, Fourth Edition provides a convenient reference for oil field workers who do not use formulas and calculations on a regular basis, aiming to help reduce the volume of materials they must carry to the rig floor or job site. Starting with a review of basic equations, calculations, and featuring many examples, this handy reference offers a quick look-up of topics such as drilling fluids, pressure control, engineering calculations, and air and gas calculations. The formulas and calculations are provided in either English field units or in metric units. This edition includes additional coverage on cementing, subsea considerations, well hydraulics, especially calculating for hydraulic fracturing methods, and drill string design limitations. This practical guide continues to save time and money for the oil field worker or manager, with an easy layout and organization to help confidently conduct operations and evaluate the performance of wells on-the-go. - Features a new chapter focused on cementing - Includes on-the-job answers and formulas for today's hydraulic fracturing methods - Provides extra utility with an online basic equation calculator for 24/7 problem-solving access - Covers topics such as drilling fluids, pressure control, engineering calculations, and air and gas calculations

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.
