A mathematical process by which data are used to generate a
model that is consistent with the data, the process of solving the
inverse problem. In
seismology, surface
seismic data, vertical seismic profiles and
well log data can be used to perform inversion, the result of which is a model of Earth layers and their thickness, density and P- and
S-wave velocities. Successful seismic inversion usually requires a high signal-to-noise ratio and a large bandwidth.
