This book introduces geophysicists and geologists to the technique of interpreting 3-D seismic data. The topics it covers include basic structural interpretation and map-making; the use of 3-D visualization methods; interpretation of seismic amplitudes; the generation and use of AVO and acoustic impedance datasets; and time-lapse seismic mapping. Written by professional geophysicists with many years of working experience in the oil industry, the book will be indispensable for graduate students, researchers, and new entrants into the petroleum industry.
