Seismic waves are primarily used to identify subsurface structure, but they also contain valuable information about the rock and fluid properties of the formations they pass through. The process of seismic inversion uses calibration information from wells to extract formation properties from seismic reflection amplitudes. This article examines inversion and presents examples from 3D, time-lapse and multicomponent surveys.
