This book explains the theory, numerical modeling, and applications of a borehole electromagnetic telemetry system used for wireless communication between the downhole tool and the surface control center during oilfield drilling. The authors begin by introducing borehole electromagnetic telemetry and explaining each part of the system with schematics and illustrations. They describe the working principle and compare it with other borehole wireless communication methods, such as mud pulse telemetry. They then address 2D and 3D electromagnetic telemetry modelling, listing previous 2D and 3D modeling methods and detailing the advantages and limitations, before discussing their recent work on a novel layered finite element method for 2D electromagnetic telemetry modelling, and on 3D electromagnetic modelling based on integral equation, thin wire kernel, and layered medium Green’s functions. Lastly, the authors show applications of electromagnetic telemetry, including single well borehole wireless communication and cross well communication in pad drilling. This includes photos, figures, and field data from real oilfield jobs. This book is a useful reference for drilling engineers, well logging tool research and development scientists and researchers, as well as for students in the areas of petroleum engineering and electrical engineering.

Theory of Electromagnetic Well Logging provides a much-needed and complete analytical method for electromagnetic well logging technology. The book presents the physics and mathematics behind the effective measurement of rock properties using boreholes, allowing geophysicists, petrophysisists, geologists and engineers to interpret them in a more rigorous way. Starting with the fundamental concepts, the book then moves on to the more classic subject of wireline induction logging, before exploring the subject of LWD logging, concluding with new thoughts on electromagnetic telemetry. Theory of Electromagnetic Well Logging is the only book offering an in-depth discussion of the analytical and numerical techniques needed for expert use of those new logging techniques. - Features in-depth analysis of the analytical and numerical techniques needed for expert use of logging techniques - Includes software codes, providing a handy tool for understanding logging tool physics and design of new logging tools - Provides a detailed glossary of all key terms within the introductory chapter

The third edition of Air and Gas Drilling Manual describes the basic simulation models for drilling deep wells with air or gas drilling fluids, gasified two-phase drilling fluids, and stable foam drilling fluids. The models are the basis for the development of a systematic method for planning under balanced deep well drilling operations and for monitoring the drilling operation as well as construction project advances. Air and Gas Drilling Manual discusses both oil and natural gas industry applications, and geotechnical (water well, environmental, mining) industry applications. Important well construction and completion issues are discussed for all applications. The engineering analyses techniques are used to develop pre-operations planning methods, troubleshooting operations monitoring techniques and overall operations risk analysis. The essential objective of the book is drilling and well construction cost management control. The book is in both SI and British Imperial units. - Master the air and gas drilling techniques in construction and development of water wells, monitoring wells, geotechnical boreholes, mining operations boreholes and more - 30% of all wells drilled use gas and air, according to the U.S. Department of Energy estimates - Contains basic simulation equations with examples for direct and reverse circulation drilling models and examples for air and gas, gasified fluids, and stable foam drilling models
