Inversion can be defined as a procedure for obtaining models that adequately describe a data set. In the case of geophysical data, our observations show the effects of rock properties on physical phenomena such as seismic-wave propagation. Because geophysical inversion allows us to extract geologic-model information from these data, the procedure is of interest to earth scientists.

Fundamentals of Geophysical Interpretation, SEG Geophysical Monograph Series No. 13, is a practical handbook for the petroleum geophysicist. Fundamental concepts are explained using heuristic descriptions of seismic modeling, deconvolution, depth migration, and tomography. Pitfalls in processing and contouring are described briefly. Applications include petroleum exploration of carbonate reefs, salt intrusions, and overthrust faults. The book includes past, present, and possible future developments in time-lapse seismology, borehole geophysics, multicomponent seismology, and integrated reservoir characterization.
