Measurement While Drilling (MWD) Signal Analysis, Optimization and Design


Book Description

Trade magazines and review articles describe MWD in casualterms, e.g., positive versus negative pulsers, continuous wavesystems, drilling channel noise and attenuation, in very simpleterms absent of technical rigor. However, few trulyscientific discussions are available on existing methods, let alonethe advances necessary for high-data-rate telemetry. Withouta strong foundation building on solid acoustic principles, rigorousmathematics, and of course, fast, inexpensive and efficient testingof mechanical designs, low data rates will impose unacceptablequality issues to real-time formation evaluation for years tocome. This book promises to change all of this. The lead authorand M.I.T. educated scientist, Wilson Chin, and Yinao Su,Academician, Chinese Academy of Engineering, and other teammembers, have written the only book available that developsmud pulse telemetry from first principles, adapting sound acousticprinciples to rigorous signal processing and efficient wind tunneltesting. In fact, the methods and telemetry principlesdeveloped in the book were recently adopted by one of theworld’s largest industrial corporations in its mission toredefine the face of MWD. The entire engineering history for continuous wave telemetry iscovered: anecdotal stories and their fallacies, original hardwareproblems and their solutions, different noise mechanisms and theirsignal processing solutions, apparent paradoxes encountered infield tests and simple explanations to complicated questions, andso on, are discussed in complete “tell all” detail forstudents, research professors and professional engineersalike. These include signal processing algorithms, signalenhancement methods, and highly efficient “short” and“long wind tunnel” test methods, whose results can bedynamically re-scaled to real muds flowing at any speed. Amust read for all petroleum engineering professionals!




Measurement While Drilling


Book Description

Trade magazines and review articles describe MWD in casual terms, e.g., positive versus negative pulsers, continuous wave systems, drilling channel noise and attenuation, in very simple terms absent of technical rigor. However, few truly scientific discussions are available on existing methods, let alone the advances necessary for high-data-rate telemetry. Without a strong foundation building on solid acoustic principles, rigorous mathematics, and of course, fast, inexpensive and efficient testing of mechanical designs, low data rates will impose unacceptable quality issues to real-time formation evaluation for years to come. This all-new revised second edition of an instant classic promises to change all of this. The lead author and M.I.T.-educated scientist, Wilson Chin, has written the only book available that develops mud pulse telemetry from first principles, adapting sound acoustic principles to rigorous signal processing and efficient wind tunnel testing. In fact, the methods and telemetry principles developed in the book were recently adopted by one of the world's largest industrial corporations in its mission to redefine the face of MWD. The entire engineering history for continuous wave telemetry is covered: anecdotal stories and their fallacies, original hardware problems and their solutions, different noise mechanisms and their signal processing solutions, apparent paradoxes encountered in field tests and simple explanations to complicated questions, and so on, are discussed in complete "tell all" detail for students, research professors and professional engineers alike. These include signal processing algorithms, signal enhancement methods, and highly efficient "short" and "long wind tunnel" test methods, whose results can be dynamically re-scaled to real muds flowing at any speed. A must read for all petroleum engineering professionals!

Borehole Electromagnetic Telemetry System


Book Description

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.
