Thus, in this course we shall primarily restrict our discussion to those inversion methods which attempt to recover a broadband pseudo-acoustic impedance log from a band-limited seismic trace.Īnother way to look at inversion is to consider it as the technique for creating a model of the earth using the seismic data as input. The above definition is so broad that it encompasses virtually all the work that is done in seismic analysis and interpretation.
Geophysical inversion involves mapping the physical structure and properties of the subsurface of the earth using measurements made on the surface of the earth. The most general definition is as fol1ows: It would therefore seem appropriate to begin by defining what is meant by seismic inversion. This course is intended as an overview of the current techniques used in the inversion of seismic data.
