Completely revised and updated, this new edition of the popular and highly regarded textbook, Applied Geophysics, describes the physical methods involved in exploration for hydrocarbons and minerals. These tools include gravity, magnetic, seismic, electrical, electromagnetic, and radioactivity studies. All aspects of these methods are described, including theoretical considerations, data acquisition, and data processing and interpretation, with the objective of locating concentrations of natural resources and defining their extent. In the past fourteen years or so since the writing of Applied Geophysics, there have been many changes in the field of exploration geophysics. The authors give full treatment to changes in this field, which include improved techniques for calculating gravity fields, the use of proton-precession and optically-pumped magnetometers, improved quality of seismic data, magnetotelluric as a practical exploration method, new electromagnetic exploration methods, the use of gamma-ray spectrometers in radioactive exploration, and improved well-logging techniques. The intent is to be practical, and thus many actual examples and problems are given. Moreover, wherever possible in this edition the authors adopt the use of Systè me Internationale (SI) units, which were not in standared use at the time of the first edition. The reader needs only a general background knowledge of geology, physics, and mathematics. Most of the math can be skipped by those interested only in the results. Advanced mathematical concepts are explained in the appendix.

'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
