Well Logging for Earth Scientists

Well logging lies at the intersection of applied geophysics, petroleum or geotechnical engineering, and applied geophysics. It has its roots in the tentative electrical measurements in well bores which were made by the Schlumberger brothers some 75 years ago in the earliest days of systematic petroleum exploration. Nowadays a vast variety of specialized instruments is used to obtain measurements from the borehole also during the drilling process.This readable and authoritative treatment of the physics of measurements obtained by latest generation of tools and how they relate to rock physics, dispels the "black magic" of well log interpretation. It offers a thorough expose of the physical basis of geophysical measurements in wells, as well as an introduction to practical petrophysics, extracting desired properties from well log measurements. A detailed review of the physics of measurements is combined with an extensive introduction to their interpretation."Well Logging for Earth Scientists", 2 nd edition, is thoroughly revised and extended with three new chapters, many new illustrations and expanded and updated references per chapter.
