This is the completely revised and updated version of the popular and highly regarded textbook, Applied Geophysics. It describes the physical methods involved in exploration for hydrocarbons and minerals, which include gravity, magnetic, seismic, electrical, electromagnetic, radioactivity, and well-logging methods. All aspects of these methods are described, including basic theory, field equipment, techniques of data acquisition, data processing and interpretation, with the objective of locating commercial deposits of minerals, oil, and gas and determining their extent. In the fourteen years or so since the first edition of Applied Geophysics, many changes have taken place in this field, mainly as the result of new techniques, better instrumentation, and increased use of computers in the field and in the interpretation of data. The authors describe these changes in considerable detail, including improved methods of solving the inverse problem, specialized seismic methods, magnetotellurics as a practical exploration method, time-domain electromagnetic methods, increased use of gamma-ray spectrometers, and improved well-logging methods and interpretation.

"It is an excellent text book [...] it will serve well as a reference for practising geophysicists and for other earth scientists who become closely involved with geophysical prospecting. I believe that it will be necessary for almost every practising exploration geophysicist to have a copy available to him. The book is well produced."
- G. V. Keller, EOS: Transactions, American Geophysical Union
"This book provides a thorough and comprehensive treatment of the various geophysical measurements used in the search for hydrocarbons and other materials. An obvious effort has been made to describe pertinent geologic concepts in ways that make understanding easier for physicists, mathematicians, and electrical engineers."
- Mahlon M. Ball, American Association of Petroleum Geologists Bulletin
"This particular volume is an excellent complete treatment of applied geophysics, useful both as a comprehensive textbook and as a basic reference. The knowledgeable economic geologist can be well prepared for a variety of important applications of geophysical methods. A total compilation in exploration geophysics."
- John A. Sumner, Economic Geology
