Over 330 clear color photos display the wide array of equipment once used to log high timber that are now eminently collectible, including axes, saws, filing tools, springboards, oil bottles, undercutters, wedges, marlin spikes, drag saws, and venerable chainsaws. Historical photos display towering giants of old growth forests where loggers toiled decades ago. An informative text provides useful information on cleaning and preserving the antique logging tools, descriptions of them, values, and a bibliography. This book will be treasured by all who share a fascination for logging as it was done by the lumberjack, bucker, and high climber.

This book primarily focuses on the principles and applications of electric logging, sonic logging, nuclear logging, production logging and NMR logging, especially LWD tools, Sondex production logging tools and other advanced image logging techniques, such as ECLIPS 5700, EXCELL 2000 etc. that have been developed and used in the last two decades. Moreover, it examines the fundamentals of rock mechanics, which contribute to applications concerning the stability of borehole sidewall, safety density window of drilling fluid, fracturing etc. As such, the book offers a valuable resource for a wide range of readers, including students majoring in petrophysics, geophysics, geology and seismology, and engineers working in well logging and exploitation.

A comprehensive history: from rough and tough handlogging to modern day helicopter and skyline logging. With generous oral histories and photographs old and new.

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

Logging has been a way of life in the Pacific Northwest, a thread woven into the character of communities, for more than a century. And in this far corner, James LeMonds's family has done about every job in the woods-working as high climbers and whistle p

Formation Evaluation with Pre-Digital Well Logs covers the practical use of legacy materials for formation evaluation using wireline logging equipment from 1927 until the introduction of digital logging in the 1960s and '70s. The book provides powerful interpretation techniques that can be applied today when an analyst is faced with a drawer full of old "E logs." It arms the engineer, geologist and petrophysicist with the tools needed to profitably plan re-completions or in-fill drilling in old fields that may have been acquired for modern deeper and/or horizontal drilling. - Includes more than 150 figures, log examples, charts and graphs - Provides work exercises for the reader to practice log analysis and formation evaluation - Presents an important source for academia, oil and gas professionals, service company personnel and the banking and asset evaluation teams at consultancies involved in reserve and other property evaluation
