Beschreibung
Well logging lies at the intersection of applied geophysics, petroleum and geotechnical engineering. It has its roots in the tentative electrical measurements in well bores which were made by the Schlumberger brothers some 80 years ago in the earliest days of systematic petroleum exploration. Today, a variety of specialized instruments is used to obtain measurements from the borehole during, as well as after, the drilling process. This readable and authoritative treatment of the physics of these measurements dispels the "black magic" of well log interpretation by relating them, including those obtained by the latest generation of tools, to rock physics. It offers a thorough exposé of the physical basis of borehole geophysical measurements, as well as an introduction to practical petrophysics -- extracting desired properties from well log measurements.
"Well Logging for Earth Scientists", 2 nd edition, is thoroughly revised and extended with three new chapters, manynew illustrations and expanded and updated references in each chapter.
Audience: This graduate level textbook with many exercises can also serve as a useful handbook for practicing earth scientists (geophysicists, geologists, or petroleum engineers).
Two decades ago, the first edition of this book demystified the process of well log analysis for students, researchers and practitioners. Since then, the industry has changed enormously: technical staffs have been slashed, and hydrocarbons have become increasingly harder to locate, quantify, and produce. In addition, new techniques of drilling have engendered a whole new family of measurement devices incorporated into the drilling string. Petroleum deposits are becoming scarce, while demand steadily increases. Massive corporate restructuring and the "graying" of the workforce have caused the technical competence involved in the search and exploitation of petroleum to become scarce. In this comprehensive update, the authors include all of the new logging measurement technology developed in the last twenty years and expand the petrophysical applications of the measurements. In sum, this is a thoroughly revised graduate level textbook, as well as a useful handbook for any practicing earth scientist.
