Geophysics, a major discipline of the Earth sciences and a sub-discipline of physics, is the study of the whole Earth by the quantitative observation of its physical properties. Geophysical data are used in academics to observe tectonic plate motions, study the internal structure of the Earth, supplement data provided by geologic maps, and to nondestructively observe shallow deposits. In industries, geophysical data are used to analyze potential petroleum reservoirs and mineral deposits, to locate groundwater, and in work on environmental remediation. The theories and techniques of geophysics are employed extensively in the planetary sciences in general.

An attempt is made in this book to introduce to the readers the important aspects of Geophysics. A conceptual geophysical exploration strategy has also been attempted in this book, distilling the knowledge gained from three decades of exploration. Geophysics in the exploration for lignite, application of Geophysics in tackling problems of mining as well as environmental issues too has been considered. Thus, the roles of Geophysics in all stages are comprehensively presented in this monograph.

This book is suitable for geophysicists, geologists, scientists, universities, organizations, teachers, students and other working in different disciplines of petroleum science and engineering.
